This Chapter regulates new and existing structures and land uses in the combining districts established by Section 20-20.020 (Zoning Map and Zoning Districts). The provisions of this Chapter provide guidance for development in addition to the standards and regulations of the primary zoning districts, where important site, environmental, safety, compatibility, or design issues require particular attention in project planning.
(Ord. 3677 § 1, 2004)
The provisions of this Chapter apply to proposed land uses and development in addition to all other applicable requirements of this Zoning Code. Any perceived conflict between the provisions of this Chapter and any other provision of this Zoning Ordinance shall be resolved in compliance with Section 20-12.020.D (Rules of Interpretation—Conflicting requirements).
A. 
Mapping of combining districts. The applicability of any combining district to a specific site is shown by the combining district Zoning Map symbol established by Section 20-20.020 (Zoning Map and Zoning Districts), being appended as a suffix to the symbol for the primary zoning district on the Zoning Map. The combining districts are applied to property through the rezoning process (Chapter 20-64), subject to any specific rezoning Requirements of the applicable combining district.
B. 
Allowed land uses, permit requirements, development standards. Except as may be otherwise provided by this Chapter for a specific combining district:
1. 
Any land use normally allowed in the primary zoning district by this Division may be allowed within a combining district, subject to any additional requirements of the combining district;
2. 
Development and new land uses within a combining district shall obtain the land use permits required by this Division for the primary zoning district; and
3. 
Development and new land uses within a combining district shall comply with all applicable development standards of the primary zoning district, except as modified by this Chapter.
(Ord. 3677 § 1, 2004)
A. 
Purpose. The Gateway (-G) combining district is intended to identify areas designated by the General Plan as visual entries into the City, and to provide special design criteria for proposed development at each entry.
B. 
Applicability. Implementation of the design criteria shall be through private and public development and improvement plans. Landscaping features may be a requirement of private development while signing and other public improvements shall be provided by public resources and completed on a phasing or priority basis.
C. 
Locations of combining district. The standards of this Section apply to the following identified entry ways; affected properties are designated within the -G combining district on the Zoning Map.
1. 
Major entries:
North—Highway 101 at the at the northern Urban Boundary;
South—Highway 101 at the intersection of Santa Rosa Avenue and 101;
East—Highway 12 at the intersection of North Melita Road;
West—Highway 12 Urban Boundary, i.e., Fulton Road.
2. 
Minor entries:
a. 
Urban arterials:
Old Redwood Highway;
Guerneville Road;
Santa Rosa Avenue.
b. 
Rural roads:
Petaluma Hill Road;
Calistoga Road;
Bennett Valley Road;
Piner Road;
Fulton Road;
Stony Point Road;
Hall Road.
D. 
Development standards and guidelines. The following standards apply to public and private development proposed within the -G combining district, as noted.
1. 
Major entries—Highway 101. The northern entry along Highway 101 should be at the urban boundary line and will be a stark transition where rural countryside abuts the urban edge. Significant setbacks and dense landscaping will soften the visual transition.
The southern entry shall occur at the urban boundary when Santa Rosa Avenue meets Highway 101. The community separator shall divide this area from the north end of Rohnert Park. The transition from rural to urban will be assisted by significant setbacks and dense landscaping. The triangular, remnant Caltrans property shall be landscaped by the City and have a sign introducing Santa Rosa at its foreground.
a. 
Setbacks. Setbacks to buildings for new projects along Highway 101, at both the north and the south entries to the City shall be 100 feet from the freeway right-of-way. Substantial landscaping and parking (if adequately screened), may be used in the setback areas. Entry length shall be the equivalent of one parcel or approximately 200 feet in length.
b. 
Landscaping. Landscaping within setbacks shall provide a minimum of 20 feet of on-site planting in addition to any existing or proposed freeway landscaping.
c. 
Screening. Rear service yards, project storage areas, and parking lots adjacent to Highways 101 shall be adequately screened. Screening may be by landscaped berms and dense tree planting or combination of fences and landscaping.
2. 
Major entries—Highway 12. The eastern entry shall occur at Highway 12, at the urban boundary line, approximately North Melita Road. A sign denoting entrance to Santa Rosa should be placed here.
The western major entry is at the urban boundary where Highway 12 meets Fulton Road. The entry is emphasized by the community separation to the west and the abrupt urban edge at Fulton Road. Setbacks to structures are the primary design criteria to be considered at this City entrance. Setbacks to structures on the north side of Highway 12 are controlled by the frontage road (Occidental Road). Setbacks on the south side have been significant due to the non-development of the old railroad right-of-way. Should the railroad right-of-way be in public use, it should be appropriately landscaped and a sign installed to denote entrance to Santa Rosa. Signing and area landscaping would then occur on State property with State permission.
a. 
Setbacks. Setbacks to buildings for new projects along Highway 12 east and west shall observe a minimum 50-foot setback. A minimum of 20 feet of dense landscaping shall also be required from the highway right-of-way.
b. 
Landscaping. Landscaping within setbacks shall provide a minimum of 20 feet of on-site planting in addition to any existing or proposed freeway landscaping.
c. 
Screening. Rear service yards, project storage areas, and parking lots adjacent to Highway 12 shall be adequately screened. Screening may be by landscaped berms and dense tree planting or combination of fences and landscaping.
3. 
Minor entries.
a. 
Bennett Valley Road. The secondary eastern entry to the City is from Bennett Valley Road. The entry point on Bennett Valley Road shall occur at the urban boundary which is adjacent to the Bennett Valley Golf Course. This entry, like the other secondary City entries is dramatic in its change from urban to rural. It is a natural to man-made demarcation that should remain for many years to come. Like the other entry treatments, special landscape and sign features announcing the entrance to the City should occur.
b. 
Hall Road—Guerneville Road—Piner Road. The City entry from the west, other than Highway 12, is by way of Hall, Guerneville or Piner Roads. Each entry should occur at the urban boundary which is either at Fulton Road or just gradually west of Fulton Road. At each location the distinction of City entry should be discernable due to the sharp change that occurs between rural and urban land use, and development improvements. Guerneville and West Third Street (opposite Hall Road) are slated to have landscape median strips. The design criteria for each of these entry ways shall be to have a special landscape feature, including signing at the intersection where each intersects with Fulton Road.
c. 
Old Redwood Highway. Entering the city from Old Redwood Highway presently has no clear presence. This is primarily due to the absence of urban level development. Existing development is rural in nature. The entry should occur at the urban boundary, which is located at the north end of the former Stevenson Equipment property. Urban level landscaping at the street frontage, signing announcing entering Santa Rosa.
d. 
Santa Rosa Avenue. As one enters the City on Santa Rosa Avenue, a landscape median shall be provided down the center of the street. Twenty feet of landscape setbacks shall be required along each property frontage. A dual row of unified street trees shall be planted across the frontage as required by the County's South Santa Rosa Avenue Design Guidelines.
e. 
Stony Point Road and Petaluma Hill Road. Secondary southern entry ways should occur at Stony Point Road and Petaluma Hill Road, each at the urban boundary line. Each are rural roads that connect to outside communities and towns. Each, like other rural roads, transitions sharply as one enters the City from the County area. Design criteria for each of these entry ways is to feature landscaped yards and signing announcing Santa Rosa. Landscape setbacks of at least 15 feet should be provided along each street frontage with common street trees provided.
(Ord. 3677 § 1, 2004)
A. 
Purpose. The -H combining district is intended to recognize, preserve, and enhance Santa Rosa's locally designated historic resources.
B. 
Applicability. The -H combining district shall apply to all properties within designated preservation districts, including both contributing and non-contributing parcels. Additionally, the -H combining district shall apply to all locally designated landmark properties. The -H combining district may be combined with any primary zoning district established by Section 20-20.020 (Zoning Map and zoning districts).
C. 
Allowed land uses and permit requirements. Any land use normally allowed in the primary zoning district by this Division may be allowed within the -H combining district, subject to the land use permit requirements of the primary district, the procedural requirements of Chapter 20-58 (Historic and Cultural Preservation), and any district specific standards as outlined below.
D. 
Character defining elements.
1. 
Purpose. Character defining elements are specific to each preservation district and are intended to identify those physical aspects that represent the historical significance of the district and are essential to maintaining and enhancing the unique character of the individual district. On March 15, 2006, Cultural Heritage Board Resolution No. 209, adopted character defining elements for the Burbank Gardens, Cherry Street, Ridgway, McDonald, Olive Park, St. Rose, West End and Railroad Square Preservation Districts, reflected in the subsections below.
2. 
Applicability. The character defining elements provide an outline of the historic context for each preservation district to project sponsors such as developers, property owners, architects, and designers. These district specific frameworks will be used by City staff, boards and commissions, and the City Council when evaluating project proposals that impact properties or existing buildings within designated preservation districts. Although each individual element may not be appropriate to each project, each project shall enhance the contextual framework of the district.
3. 
Elements to consider in all preservation districts include:
a. 
Architecture.
Residential structures relate to each other in terms of size, scale, mass and rhythm.
Buildings in preservation districts utilize traditional building materials.
In general, buildings do not exceed 35 feet in height.
Houses have articulated, pedestrian-friendly frontages and are not dominated by garages.
Most houses have front porches.
b. 
Hardscape.
Residential driveways are generally single wide rather than double wide.
Concrete sidewalks are scored in one- to two-foot squares.
Traditional light standards are found in each preservation district.
c. 
Landscape.
Mature landscape predominates in preservation districts.
Landscaping typically does not obscure buildings.
d. 
Site planning.
Garages and parking are located to the rear of the property.
Houses are typically set back from the sidewalk a minimum of 15 feet.
Houses typically maintain a minimum of five-foot side yard setback.
Each preservation district offers a community-serving facility within a short walking distance.
E. 
Site planning and development standards. Development within the -H combining district shall comply with the following standards, and the requirements of Chapter 20-58 (Historic and Cultural Preservation). In the event of any conflict between the following standards and those of the primary zoning district, those applicable to the -H combining district shall apply.
1. 
Processing Review Procedures. The Processing Review Procedures for Owners of Historic Properties were adopted by the City Council as Santa Rosa's local guidelines for alterations to properties within designated preservation districts or individually designated landmark properties. These guidelines are referred to in findings for approval of a Landmark Alteration Permit and provide a basis for objective and consistent decision-making by the review authority.
2. 
Secretary of the Interior's Standards. The Secretary of the Interior's Standards for Rehabilitation are the accepted standards used on the national, state, and local level for assessing the impacts of alterations to historic resources and their significance. These standards have been adopted by reference within the Processing Review Procedures, and consistency with applicable standards is a required finding for approval of a Landmark Alteration Permit.
3. 
Height limits.
a. 
Purpose. In an effort to preserve and enhance neighborhood character within designated preservation districts, height limits within the combining district are more restrictive than the height limits of the primary zoning district.
b. 
Height limit. No structure within the -H combining district shall exceed a maximum height of 35 feet and two stories, except as provided in Subsection E.3.c.
c. 
Increased height. A structure may be approved with a height over 35 feet or two stories provided that:
(1) 
The review authority finds that the increased height does not detract from the character of the preservation district or any adjacent contributing properties; and
(2) 
The review authority may require conditions of approval that pertain to the placement of screens, the location and type of openings, the location and projections of sun decks, porches, balconies, patios, and similar architectural amenities, to enhance or preserve the residential privacy of the proposed structures and of any adjacent existing or anticipated residential structures or uses.
4. 
Setbacks.
a. 
Purpose. The historic development pattern is a unique and defining feature in each of the City's preservation districts and on each landmark property. Standard setback requirements may not be sensitive to such unique attributes and therefore it is important to allow flexibility in determining appropriate setbacks to preserve and enhance existing conditions or character.
b. 
Applicability. Reduced setbacks may be applied to development within a designated preservation District or on a designated local landmark. The reduced setback may be applied to new buildings as well as the addition or expansion of an existing building.
c. 
Reduced setbacks. A reduction of setbacks required by the primary zoning district may be approved provided that:
(1) 
The review authority first finds that the reduced setback will not significantly impair the Residential privacy of the proposed structures or any adjacent existing or anticipated residential structures or use; and
(2) 
The review authority first finds that the reduced setback enhances and protects the historic development pattern of the preservation district or any adjacent contributing properties and that approving a reduced setback facilitates a superior project.
F. 
West End Preservation District.
1. 
Designation. The West End Preservation District was designated by the City Council on August 13, 1996 (Resolution #22811) after recommendation by the Cultural Heritage Board on May 28, 1996 (Resolution #0063).
2. 
Boundaries. The West End Preservation District is bounded by West 9th Street on the north; Santa Rosa Creek and West 6th Street on the south; Northwestern Pacific Railroad tracks on the east; and North Dutton Avenue on the west. See Figure 2-2.
Figure 2-2—West End Preservation District
3. 
Context statement. The West End Preservation District is significant for architecture as a large and reasonably intact 19th and early 20th century working-class residential district comprised of small houses on the "wrong side of the tracks," and for its ethnic history as Santa Rosa's large and long-standing Italian neighborhood. The large 'Italian Town' in and around the West End district is Santa Rosa's only historic ethnic neighborhood. Besides representing a good cross section of very modest residential architecture of the 1870s through the 1940s, the West End shows traces of its heritage in its rustic landscaping, stonework and folk art, and the generally handmade character of the home improvements.
The residential development of the District can be seen in the architectural progression of West 6th, 7th, and 8th Streets. Early construction can be found on West 6th Street, examples of the late 1890s on West 7th Street, and earth 20th century styles are visible on West 8th Street. These streets combined with others in the District are an important part of the historic building fabric. The DeTurk Winery and the Burris Distillery buildings are important early commercial/industrial buildings. The DeTurk Round Barn, which is unusual in its design and one of few in the country, is currently used as a public assembly facility.
4. 
Period of significance. 1870s to1940s.
5. 
Neighborhood character. The West End Preservation District is significant as a predominantly single-family residential neighborhood made up of modest houses on narrow, deep lots. Although a variety of architectural styles are found within the neighborhood, as listed below, homes are predominately bungalows and Queen Anne or Colonial cottages. Although not uniform, front setbacks are generally similar, with some articulation on any given blockface.
Commercial buildings including Franco American Bakery, Starks Steakhouse, Western Farms Center, and community facilities including CHOPS, DeTurk Round Barn, and DeMeo Park contribute to the character of the neighborhood.

G. 
Railroad Square Preservation District.
1. 
Designation. The Railroad Square Preservation District was designated by the Cultural Heritage Board on November 14, 1990 (Resolution #0026). The Railroad Square National Register Historic District was listed on the National Register of Historic Places in 1979.
2. 
Boundaries. The Railroad Square Preservation District is bounded by 6th Street on the north; 3rd Street on the south; U.S. 101 Freeway on the east; and Santa Rosa Creek on the west. The locally designated Preservation District encompasses and expands the boundaries of the National Register District. See Figure 2-3.
Figure 2-3—Railroad Square Preservation District
3. 
Context statement. The Railroad Square Preservation District is a homogeneous mixture of building styles and construction techniques, not found elsewhere in the City, that reflect its commercial development during the railroad era, and the final onslaught of post World War II freeway systems which effectively divided the district from the central downtown area and allowed it to retain its links with transportation systems of the past. The district maintains most of its original composition and the commercial storefronts, hotels, and remaining warehouses represent a fairly accurate snapshot of Railroad Square during the height of rail travel and commerce and its rebirth after the 1906 earthquake.
Fourth Street, the main thoroughfare through the District, begins as a tree shaded park located next to a 1904 Railroad Depot (4th Street and Wilson Street) constructed from locally quarried basalt. The Depot is one of four such blue basalt buildings located within the District, all of which are of significant historic and architectural value (Western Hotel at 10 4th Street, LaRose Hotel at 100 5th Street, and REA Express Building at 9-11 5th Street). Along 4th Street is a series of one-story brick commercial buildings built from 1915 to 1925. Adjacent to the railroad tracks, which form a ribbon through the western end of the District, is a series of brick warehouses built from 1888 to 1914. The commercial brick buildings located in the District are of particular importance because the 1906 and 1969 earthquakes, as well as urban renewal, destroyed most of those found within Santa Rosa City limits.
4. 
Period of significance. 1888 to1923.
5. 
District character. Railroad Square is comprised of five distinct architectural areas which reflect the evolution of this historic commercial district: west of the tracks with brick warehouses and wooden loading docks (1888 to 1915); 3rd Street between Wilson and Davis Streets with newer buildings; South side of 4th Street with predominately painted brick storefronts built after the 1906 earthquake; and the north side of 4th Street with Mission Revival Style false front buildings built between 1911 and 1913. The signature blue basalt buildings built between 1903 and 1915 and surrounding Depot Park are the architecturally significant buildings that qualified the District for its National Register designation.
Existing buildings in the District are typically single-story, with heights ranging from 22 to 27 feet. The dominant building materials are brick, painted and unpainted, stone masonry (basalt), and stucco. The color palette of the district is generally muted. Glass transoms and large storefront windows are typical of store-fronts. Historic window types are generally wood, painted metal, or copper.
Roof parapets are found on most commercial storefronts, obstructing flat or low pitched roofs and screening roof equipment from street level view. Although the heights of the parapets vary, they are usually harmonious with adjacent buildings. Windows on the upper façades are regularly spaced.
Buildings reflect a commercial theme with simple detailing and human scale. In addition to the commercial brick buildings on the south side of 4th Street and the four basalt buildings in the district, common architectural themes are rooted in the Mission Revival and Spanish Revival architectural styles.

Large storefront windows are 10 feet with transoms above and a wood panel or glazed tile kickplate beneath.
Storefront have single light wood framed entry doors that are recessed.
Glazed decorative tile detailing and wood paneling below windows is typical.
Heights of the parapets vary, but they are usually harmonious with adjacent buildings.
Signage appropriate to the era.
Period light fixtures.
Sidewalks with brushed cement and two-foot squares.
7. 
Signs. Retaining and restoring original signs which have traditionally linked Railroad Square buildings to their environment is a primary goal. New signs shall be designed to be compatible with the character of Railroad Square in size, scale, material, and color. In approving sign permits for Railroad Square, the review authority shall make the consider the following criteria:
a. 
The original signs and building graphics have been restored wherever possible. The size, type, location and quantity shall be calculated in compliance with Zoning Code Chapter 20-38, which regulates signs;
b. 
The proposed signs are compatible with the character of the building and the district in terms of scale, materials, and color;
c. 
The proposed sign adheres to Railroad Square's overall design concept of retaining and enhancing the distinctive architectural character that existed between 1900 and the1930s;
d. 
The proposed signage is oriented to the pedestrian as the primary user of the Railroad Square historic specialty shopping area; and
e. 
Signage for upper story tenants is comprised of painted lettered window signs similar to the gold-leaf type or similarly compatible.
H. 
St. Rose Preservation District.
1. 
Designation. The St. Rose Preservation District was designated by the Cultural Heritage Board on November 28, 1990 (Resolution #0027).
2. 
Boundaries. The St. Rose Preservation District is bounded by Lincoln Street (properties on both sides) on the north; 6th and 7th Streets on the south; B Street (properties on both sides) on the east; and Morgan Street on the west. See Figure 2-4.
Figure 2-4—St. Rose Preservation District
3. 
Context statement. The St. Rose Preservation District is significant for its architecture as a cross-section of Santa Rosa's residential building types and some institutional and commercial types. Though primarily residential, the district has this variety because it is adjacent to Santa Rosa's commercial core, and because similar variety, perhaps less intense, used to exist in most residential neighborhoods prior to the advent of zoning restrictions. Dates of construction vary from 1872 to 1948, but the big growth came in the early 1920s with nearly 40 new houses, all single-story, mostly bungalows along Lincoln St. Notable exceptions to the modest residences are some of Santa Rosa's grandest surviving 19th century residences.
The district grew up around St. Rose Church and school, but its main cohesiveness today results from its surroundings. In addition to the houses, the residential building types found in the district include duplexes, small apartment buildings, and a small late bungalow court. Commercial types include three Art Deco office buildings. The most prominent institution is St. Rose Church, a Romanesque Revival stone structure built by local Italian stone masons in 1900. The large St. Rose School is on another face of the same block. The Santa Rosa Post Office relocated to the St. Rose Preservation District in 1979 and is listed on the Na-tional Register; it is one of more than 12 buildings that have been moved into the district.
4. 
Period of significance. 1872 to 1948.
5. 
Neighborhood character. The St. Rose Preservation District is primarily residential with a wide range of architectural styles as shown below. The northern portion of the district has vernacular versions of the architecture reflective of residential growth in the 1920s. Houses in the southern portion of the district were built in the 1800s and reflect an older period of development.
Residential parcels are generally 40 to 50 feet wide. Single car detached garages are located on rear lot lines with narrow driveway access. Generally uniform front setbacks are found on any given block face. When found, front yard fences are typically three-foot tall picket. St. Rose has maintained the traditional two-foot sidewalk squares within the public right-of-way.
Houses are typically small, simple, and one story with stylistic elements appropriate to their dates of construction. There are several large and elaborate houses sprinkled throughout the district (Italianate, Stick, and Queen Anne). Houses are generally wood framed with narrow clapboard or shingle exteriors, although some examples of stucco exterior are found. Full or partial width porches with orientation toward the street are typical. Double hung wood sash windows in simple rectangular form are common.
Multi-pane windows are also typical. Front doors generally include windows.

Cherry Street Preservation District.
1. 
Designation. The Cherry Street Preservation District was designated by the City Council on March 24, 1992 (Resolution #20725) after recommendation by the Cultural Heritage Board on January 8, 1992 (Resolution #0039).
2. 
Boundaries. The Cherry Street Preservation District is bounded by Cherry Street (properties on both sides) on the north; 7th Street on the south; west of "E" Street on the east; and Riley Street and east of Mendocino Avenue on the west. See Figure 2-5.
Figure 2-5—Cherry Street Preservation District
3. 
Context statement. The Cherry Street Preservation District is significant for its architecture as a cross section of Santa Rosa's residential building types between 1870 and 1946. In addition to the many examples of modest 19th and 20th century dwellings, there are a large number of Victorian era mansions scattered throughout the district. Some institutional and commercial uses are found here as well. The Cherry Street District reflects the kind of diversity often found in older portions of American towns. The district derives additional significance from being the home of many early Santa Rosa leaders of commerce, government, religion and education.
The Cherry Street District is one of the oldest neighborhoods in Santa Rosa and contains the highest concentration of 19th century buildings in the City. Particularly noteworthy are the remaining Queen Anne and Stick style mansions scattered throughout the neighborhood. The district also contains fine examples of early 20th century dwellings, although these usually are of a more modest scale than their Victorian counter-parts.
For the district as a whole, the integrity is above average. Relatively little large scale exterior remodeling has occurred over the years and most structures retain stylistic elements appropriate to their dates of construction. The structural condition of most buildings appears quite sound. Cherry Street itself, the center-piece of the neighborhood, is four blocks long and is contained entirely within the confines of the district.
The irregular street pattern of the neighborhood results from conflicting grids. The grid along 7th Street follows the original downtown grid system laid out parallel to Santa Rosa Creek.
4. 
Period of significance. 1870 to 1946.
5. 
District character. The Cherry Street Preservation District is predominately made up of single-family homes and showcases a range of architectural styles. Generally, the homes in the Cherry Street District are one- or two-story and sited on original 50-foot by 100-or 150-foot lots, with lawns and mature landscaping surround the houses. Many of the larger trees in the neighborhood were planted at the time of house construction and contribute to the neighborhood character.
Cherry Street itself is the spine of the district. The district's larger homes are located on Cherry Street and the properties on the north side are alley loaded. Many of the homes on Cherry Street appear taller than more contemporary two stories due to attic space.
Defined front entries with orientation to the street are typical. Front setbacks are 15 to 20 feet with some variation on each block face, and five-foot side yard setbacks are typical. The majority of the houses are wood framed with clap board, shiplap, and shingle exteriors. Some examples of stucco are found throughout the district. Steep pitched roofs and basements are also common features of existing single-family dwellings.
There are many examples of historic double-hung wood sash windows, found both as singles and in pairs. Detached garages are located on rear and/or side property lines with narrow driveway access. Generally, accessory structures are single story, although some examples of two stories with second units above the garage are found.

Context statement. The Olive Park District is a homogeneous group of 43 residential properties and a park, and is significant as an example of Santa Rosa's residential context. The District demonstrates the housing chosen by middle-class shopkeepers and craftsmen in the early 20th century. Early residents included proprietors of a furniture store, liquor stores, gas stations, plumbing shops, an auto repair shop, a photographer, and a general contractor; as well as various craftsmen. The district also displays strong family ties to the neighborhood. The historic houses are remarkably intact and represent a fine collection of turn-of-the century styles. The feeling of a historic neighborhood is very strong here. The public park is one of Santa Rosa's oldest.
4. 
Period of significance. 1891 to 1926.
5. 
District character. Olive Park Preservation District is a quiet residential enclave bordered by bustling downtown and at the intersection of Highway 12 and Highway 101. There are a variety of architectural styles found in the District, most of which remain remarkably intact, and no two homes are alike.

Burbank Gardens Preservation District.
1. 
Designation. The Burbank Gardens Preservation District was designated by the City Council on March 25, 2003 (Resolution #25606) with recommendation of the Cultural Heritage Board on January 22, 2003 (Resolution #145).
2. 
Boundaries. The Burbank Gardens Preservation District is bounded by Sonoma Avenue and Tupper Street (east of Hendley Street) to the north, Santa Rosa Avenue to the west, Maple Street to the south, and South E Street on the east. See Figure 2-7.
Figure 2-7—Burbank Gardens Preservation District
3. 
Context statement. The Burbank Gardens Preservation District is significant in the context of the residential development of Santa Rosa. The district includes the small Riverside (1904), Freeman (1875), and Tupper (1873) additions and the larger Wheeler (1875) addition south of Charles Street. The name Burbank Gardens comes from Luther Burbank's home and gardens located in the northwest corner of the district (a City Park and local landmark, and listed on both the State and National Registers), which served as the focal point for the area's residential development between 1875 to 1903. Some of the lots on Tupper Street, closest to the Burbank House, are said to be on former Burbank property, developed by Burbank or his widow.
An 1896 Directory lists 11 residences including that of Luther Burbank. By 1903, 15 residences were listed and in six years the total had doubled to 30. Many of the early houses are found in the area of Burbank's home and gardens. Early residents included a nurseryman, railroad men, carpenters, and a paper hanger. Houses built in the northern section include examples of single-story with raised basements, reflecting not only the architectural style of the time but also their proximity to the flooding creek.
The southern section has many cottages and bungalows, all built in a modest scale.
4. 
Period of significance. 1875 to 1940s.
5. 
District character. The Burbank Gardens Preservation District is a fairly homogenous district of small single-family homes, predominately Bungalows representing the bulk of development that occurred in the 1920s and 1930s with a mix of other architectural as shown below, as well as some duplexes, apartment buildings, small commercial buildings and Burbank Home and Gardens.
Houses are generally single-story with some exceptions found in the northern portion of the district, closer to Santa Rosa Creek. Architectural detailing is minimal and simple. Double hung wood windows are common.
Typical lots are narrow, generally measuring 40 to 50 feet. Houses generally follow a similar front setback on any given block face and front stoops or small porches create clearly defined entries with orientation to the street. Front yard fencing is generally three-foot tall picket fencing if any at all. Small front yards include informal landscaping. Single car garages are located at the rear of property, often on a side property line with narrow driveway access.
Although some houses are found on Santa Rosa Avenue, in general the character along this outer edge of the district is different. Most district properties along Santa Rosa Avenue are considered noncontributing properties, although two National Register properties (Luther Burbank Home and Gardens and Park Apartments) are found along this strip.

1. 
Designation. The Ridgway Preservation District was designated by the City Council on March 6, 2007 (Resolution #3818) with recommendation of the Cultural Heritage Board on November 15, 2006 (Resolution #0225).
2. 
Boundaries. The Ridgway Preservation District is bounded by Ridgway Avenue on the north; College Avenue on the south; Mendocino Avenue on the east; and U.S. Highway 101 freeway on the west. See Figure 2-8.
Figure 2-8—Ridgway Preservation District
3. 
Context statement. Architecturally, the Ridgway Preservation District provides a panoramic view of historic progression of building styles. The District has some particularly good examples of modest, well-designed 1920s residences as well as newer dwellings constructed in the 1930s, 1940s and even the 1950s. The District encompasses an architectural time span of Santa Rosa starting with early hip roof residences, through to the Spanish or Mission Revival homes, which are found in the northeast section. Much of the early construction done in the district was the work of Roberts and Simpson who worked locally as contractors and carpenters. A number of the larger homes within the area were converted to multiple living units, probably during World War II.
There are two particularly distinctive structures on Mendocino Avenue, both designed by Petaluma architect Brainerd Jones. One is the Belvedere, a late Queen Anne built for W. H. Lumsden, now an excellent example of adaptive re-use that retains the integrity of its design both inside and out. The other is the Oates/Comstock residence, an outstanding Shingle Style house with Colonial Revival elements.

A. 
Purpose. The -SR combining district is intended to enhance and preserve the natural and constructed features that contribute to the character of scenic roads. Natural and constructed features include trees, rock walls, view corridors, road configuration and tree canopy.
B. 
Applicability. The -SR combining district may be combined with any primary zoning district established by Section 20-20.020 (Zoning Map and Zoning Districts), provided that the standards of this Section shall apply only to the portions of parcels within 125 feet or less from the edge of the pavement of the designated scenic road. All portions of a parcel more than 125 feet from the edge of the pavement of a designated scenic road shall be regulated by the standards of the primary zoning district.
C. 
Allowed land uses and permit requirements. Any land use normally allowed in the primary zoning district by this Division may be allowed within the -SR combining district, subject to the land use permit requirements of the primary district.
D. 
Site planning and development standards. Proposed development and new land uses shall comply with the following standards, as applicable. In the event of any conflict between the following standards and those of the primary zoning district, the most restrictive shall apply.
1. 
Brush Creek Road and Wallace Road. Scenic characteristics consist of the many native and ornamental trees that line the roadway as well as groups of trees found immediately adjacent to the roadway. Numerous dry-laid rock walls formed from native field stone are along properties fronting Brush Creek Road. Development density is very low and low density with varied setbacks creating a rural to semi-rural character.
a. 
Minimum Brush Creek Road-Wallace Road lot frontage: 100 feet measured at property line, provided that the access strip of a flag lot is exempt from this requirement.
b. 
Minimum setback from Brush Creek Road-Wallace Road:
(1) 
50 feet measured from edge of pavement to a one-story structure with a maximum height not exceeding 25 feet;
(2) 
100 feet measured from edge of pavement to a two-story structure, or a one-story structure with a height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Brush Creek Road or Wallace Road than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Fences, walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district.
2. 
Calistoga Road (North of Badger Avenue). Scenic characteristics consist of views over Rincon Valley as one enters Santa Rosa from the northeast. This portion of Calistoga Road is very picturesque due to the proximity of the hills and the open pasture land. Most of the area has a semirural character due to the very low density development consisting of low ranch style homes on large lots. In addition the road surface is relatively narrow with few urban improvements which reinforces the semi-rural image as one enters and leaves Santa Rosa.
a. 
Minimum Calistoga Road lot frontage:
(1) 
150 feet when a home fronts Calistoga Road;
(2) 
100 feet when a home backs or sides on Calistoga Road.
b. 
Minimum setback from Calistoga Road:
(1) 
50 feet measured from edge of pavement to back-on fencing or a one-story structure with a maximum height not exceeding 25 feet;
(2) 
100 feet measured from edge of pavement to a two-story structure or a one-story structure with a height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Calistoga Road than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Nonback-on fences and walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district
3. 
Highway 12 (Calistoga Road to Oakmont). Scenic characteristics consist of the picturesque views of the surrounding hills from the valley floor as one enters and leaves Santa Rosa. The area has a semi-rural character due to the variations in development patterns consisting of rural homes on large lots and suburban subdivisions separated by open pasture. The highway has a boulevard character due to the urban improvements with a landscaped median. As the highway leaves Santa Rosa, the character changes to a rural highway.
a. 
Minimum setback from Highway 12. The setback shall be measured from the Highway 12 right-of-way, or the back of sidewalk, whichever provides the greater setback:
(1) 
50 feet to back-on fencing or one-story structure with a maximum height not exceeding 25 feet;
(2) 
100 feet to a two-story structure or one-story with height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Highway 12 than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Nonback-on fences and walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district.
b. 
Require back-on landscaping to include dense planting of coniferous tree and shrubs to screen development from view from Highway 12.
4. 
Los Alamos Road. Scenic characteristics consist of the picturesque views of hills and valleys from the road as one enters or leaves Santa Rosa. Development along the road has a semi-rural-suburban character due to the very low density development, consisting mostly of low ranch style homes on large lots. Existing road improvements enhance the semi-rural character due to the lack of urban improvements.
a. 
Minimum lot frontage: 100 feet measured at property line; provided that the access strip of a flag lot is exempt from this requirement.
b. 
Minimum setback from Los Alamos Road:
(1) 
30 feet measured from edge of pavement to back-on fencing or one-story structure with a maximum height not exceeding 25 feet;
(2) 
100 feet measured from edge of pavement to a two-story structure or one-story structure with a height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Los Alamos Road than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Nonback-on fences and walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district.
5. 
Los Olivos Road (entire length). Scenic characteristics consist of the many native and ornamental trees that line the roadway that give the roadway a sense of shelter and offer varied patterns in light and shadow as one travels along the corridor. The very low density development and large setbacks help to establish a setting that is rural in character. In addition the road surface is relatively narrow with minimal urban improvements alone, most of its length which reinforces the image of a rural environment.
a. 
Minimum Los Olivos Road lot frontage: 100 feet measured at property line; provided that the access strip of a flag lot is exempt from this requirement.
b. 
Minimum setback from Los Olivos Road:
(1) 
50 feet measured from edge of pavement to a one-story structure with a maximum height not exceeding 25 feet;
(2) 
100 feet measured from edge of pavement to a two-story structure, or one-story structure with a height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Los Olivos Road than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Fences, walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district.
6. 
Manzanita Avenue (Entire Length). Scenic characteristics consist of the many native and ornamental trees that line the roadway that give the roadway a sense of shelter and offer varied patterns in light and shadow as one travels along the corridor. The very low density development and large setbacks help to establish a setting that is rural in character. The road surface is also relatively narrow with no urban improvements, which reinforces the image of a rural environment.
a. 
Minimum Manzanita Avenue lot frontage: 100 feet measured at property line; provided that the access strip of a flag lot is exempt from this requirement.
b. 
Minimum setback from Manzanita Avenue:
(1)

(2) 
125 feet measured from edge of pavement to a two-story structure or a one-story structure over 25 feet in height;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Manzanita Avenue than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Fences, walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative accessory structures need only comply with the setbacks and other standards of the primary zoning district.
7. 
Melita Road. Scenic characteristics consist of the many native and ornamental trees that the line the road-way that give the roadway a sense of shelter and offer varied patterns in light and shadow as one travels along the corridor. The rural character is enhanced by the very narrow width and curves of the road. In addition, portions of the road parallel Santa Rosa Creek. The most scenic areas of the road lack urban street improvements. Most of the area has a very low density rural character with relatively small homes on large lots. The road has an historic feel due to the rock walls and former stagecoach station.
a. 
Minimum Melita Road lot frontage: 100 feet measured at property line; provided that the access strip of a flag lot is exempt from this requirement.
b. 
Minimum setback from Melita Road:
(1)

(2) 
100 feet measured from edge of pavement to a two-story structure or to a one-story structure with a height over 25 feet;
(3) 
Where an existing dwelling does not comply with the above setbacks, single story additions and single story accessory structures are allowed within the above setbacks provided that an addition or accessory structure does not extend closer to Melita Road than the existing dwelling, and complies with the setbacks of the primary zoning district;
(4) 
Fences, walls, hedges, swimming pools, uncovered parking, uncovered decks, gazebos, and other decorative type accessory structures need only comply with the setbacks and other standards of the primary zoning district.
c. 
Minimum lot area. The minimum area of lots that border on Melita Road and are located in the Very Low Density General Plan designation shall be 40,000 square feet. This requirement does not apply to existing or new flag lots where only the access strip has frontage on Melita Road or the creation of a new lot where the new lot does not border on Melita Road.
8. 
Montecito Avenue (Norte Way to Chanate Avenue). Scenic characteristics consist of the many native and ornamental trees that line the roadway that give the roadway a sense of shelter and offer varied patterns in light and shadow as one travels along the corridor. The very low density development and large setbacks help to establish a setting that is rural in character. In addition the road surface is relatively narrow with no urban improvements which reinforces the image of a rural environment

9. 
Francisco Avenue (east/west portion). Scenic characteristics consist of the picturesque views of the surrounding hills from the valley floor from the northern edge of the City of Santa Rosa. The area has a semi-rural character due to the transition from the City of Santa Rosa into Sonoma County. The transition primarily consists of rural county land, characterized by rural residential development, to the north, and more urbanized subdivisions to the south.
a. 
Minimum setback from Francisco Avenue. The setback shall be measured from the Francisco Avenue back of side walk:
(1) 
14 feet to back-on fencing or one-story structure or element with a maximum height not exceeding 25 feet;

Require an 8-foot planter on the south side of the street, with trees and other low plantings, to transition from the urban characteristics of the City of Santa Rosa into the rural setting to the north. The plantings are not intended to screen the urban development, but to assist the transition.
10. 
Burbank Avenue (from the northerly boundary of Roseland Creek Community Park to Hearn Avenue). Scenic characteristics consist of larger front setbacks than typically found in low density, single-family residential areas, and a narrow roadway width that provides a "country road" feel, as well as roadside trees that create an occasional wooded "tunnel" effect. The area has a semi-rural residential character, with more urbanized subdivisions to the north and south.

As development occurs in the creek and trail activation areas shown in Figure 2-26, lighting should be provided consistent with Santa Rosa Creek Design Guidelines.
5. 
Blank façades at ground level and above should be avoided. Windows, doors and transparent opening are encouraged to provide "eyes on the creek" and heighten sense of security. To the extent feasible, surface and structured parking should not front onto the creek or trail.
H. 
Active Ground Floor Overlay. Within the Downtown Station Area Specific Plan area, active ground floor frontages are key to creating the vibrant character envisioned for the Downtown Station Area. All proposed development on a parcel designated Active Ground Floor Overlay in Figure 2-26 shall comply with the following development standards. In the event of any conflict between the following development standards and those of the primary zoning district, the most restrictive shall apply.
1. 
On corner lots where only one frontage is in the Active Ground Floor Overlay, ground floor activating strategies shall also be applied to the intersecting street frontage as appropriate, subject to review by the review authority.
2. 
New development with frontage on streets in the Active Ground Floor Overlay as shown on Figure 2-26 shall provide design features that optimize the pedestrian experience. To comply with this requirement, developments with up to 90 linear feet of frontage must provide two or more of the following and Developments with over 90 linear feet of frontage must provide three or more of the following:
Awnings or overhangs over all ground floor entrances;
One piece of street furniture per 15 linear feet of street frontage. Street furniture may include seating, ornamental planting boxes, informational kiosks, bicycle racks, or trash/recycling receptacles integrated into front setbacks where sidewalk width is not sufficient to accommodate street furniture;
Integrated public art in the form of a mural, sculpture, light display, or other original work of a permanent nature as defined in the City Code;
At least 600 square feet of publicly accessible active or passive recreational space on-site, or in the form of a curbside parklet;
A green/living wall of a size equivalent to at least 15 percent of the building façade as measured between two and 12 feet above sidewalk level;
Innovative alternative strategies to optimize the pedestrian experience along Active Ground Floor Overlay streets. Staff will evaluate proposals on a case by case basis for compliance with applicable DSASP Urban Design Principles and development standards.

(Ord. 2020-014 § 15)
A. 
Purpose. The Senior Housing (-SH) combining district is intended to create a new zoning district for senior housing and to set forth a process through which property may be rezoned specifically as housing for older persons within the City in compliance with Federal and State Fair Housing Law by establishing a clear set of requirements for senior housing.
B. 
Applicability.
1. 
The -SH combining district shall only apply to residential developments within the City of Santa Rosa proposed as senior housing that seek automobile and bicycle parking allowances based on the "senior housing project" parking requirements, pursuant to Section 20-36.040, Table 3-4 (Automobile and Bicycle Parking Requirements by Land Use Type), or any other allowances from the City based on the senior housing status. Such projects shall also include an application to be rezoned, pursuant to Chapter 20-64 (Amendments), to add the -SH combining district to the base zone for the property.
2. 
Nothing in this section shall limit the ability of a housing provider to operate housing exclusively for persons 62 years and older, or housing for persons 55 and older as otherwise permitted by and consistent with Federal and State law requirements.
C. 
Occupancy requirement. Residential units within the -SH combining district shall be occupied so that at least 80 percent of the occupied units are occupied by at least one person who is age 55 or older. The age restriction stated herein does not apply to or affect ownership of the residential units, but is an occupancy requirement.
D. 
Notification. The signage, advertising, covenant, regulations and restrictions, and leases for occupancy for all residential units within the -SH combining district shall state that the residential units are senior housing as defined in this Zoning Code.
E. 
Senior housing regulatory agreement.
1. 
Application to the Housing Authority. Once property has been zoned to the -SH combining district, the developer, owner, or homeowners' association shall file an application with the Housing Authority for the purpose of entering into a senior housing regulatory agreement, including the payment of any processing and monitoring fees. The senior housing regulatory agreement shall require that the development is at all times occupied in compliance with the requirements of this section and shall be reviewed and approved by the Executive Director of the Housing Authority.
2. 
Execution of a senior housing regulatory agreement. The owner(s) of the senior housing development shall execute a senior housing regulatory agreement prior to recording any final map or the issuance of any building permits, as applicable. The senior housing regulatory agreement shall be recorded in the Official Records of Sonoma County against each residential unit within the -SH combining district. The senior housing regulatory agreement shall be binding on future owners of the residential development.
3. 
Projects with a density bonus. A project providing residential units pursuant to the City's density bonus ordinance or the City's Housing Allocation Plan ordinance may enter into a single agreement for purposes of regulating and monitoring the senior residential units and other restrictions applicable under those chapters in accordance with the most restrictive requirements.
F. 
Verification of occupancy.
1. 
Biennial verification. As part of the senior housing regulatory agreement, the owner, or homeowners' association shall submit verification of occupancy to confirm its status as senior housing, not less frequently than biennially, through survey or affidavits, in a form to be determined by the Executive Director of the Housing Authority, which shall be consistent with the requirements and applicable regulations of the Federal Fair Housing Act and shall be submitted to and reviewed by the Housing Authority Director, or designee. The Housing Authority is hereby expressly authorized to act as the City's agent for purposes of monitoring compliance with this chapter, including enforcement pursuant to the regulatory agreement.
2. 
Failure to verify status of senior housing. Failure to submit the verification required by this section or failure of the verification to confirm that the development meets the senior housing requirements as defined in this section and consistent with Federal and State law, shall constitute a violation of the City's Zoning Code, in addition to violations under the senior housing regulatory agreement, and may be subject to enforcement pursuant to the City Code, including specifically the applicable provisions of Chapter 1-30 (Administrative Review of Ordinance Violations).
(Ord. 3997 § 2, 2012)

Note: Former Section 20-28.100 Resilient City (-RC) combining district, consisting of Ord. 2017-018 § 3; Ord. 2018-015 § 3; Ord. 2019-006 § 3; Ord. 2019-013 § 3; Ord. 2020-011 § 1; Ord. 2020-012 § 2; Ord. 2023-015, 11/28/2023 was repealed by Ord. 2024-012, 11/19/2024.
A. 
Purpose. The -MMH combining district is intended to enable the development of multifamily housing types, compatible in scale with single-family houses, in Santa Rosa's walkable neighborhoods. Housing units in Missing Middle building types offer a wide range of choices for residents and can be either rented or owned according to a condominium/airspace model; fee-simple ownership is also possible for types that do not incorporate stacked units. Deed-restricted affordable ownership and rental options are compatible with all Missing Middle Housing types.
B. 
Applicability. The -MMH combining district may be combined with any residential or mixed-use primary zoning district established by Section 20-20.020 (Zoning Map and zoning districts), provided that the standards of this section shall apply as directed.
1. 
Applicability by Location.
a. 
Eligibility for the Missing Middle Housing Bonus ("MMH Bonus") is limited to sites located in the MMH Small or MMH Medium zones ("MMH zones")—including the MMH Small Flex and MMH Medium Flex sub-zones. Projects using the MMH Bonus shall comply with the standards for the applicable MMH zone or sub-zone, as provided in Subsection C. Projects located outside of the MMH zones shall be regulated by the standards of the primary zoning district and Division 3.
b. 
The -MMH combining district, with its associated MMH zones, may be applied to additional areas in accordance with the General Plan and applicable legislation.
2. 
Applicability Limited to Missing Middle Housing Bonus Projects. Compliance with the standards in Subsections C through I is required for a project to be entitled under the MMH Bonus (Missing Middle Housing Bonus).
a. 
For projects using the MMH Bonus, the standards in this Section shall replace the corresponding standards in Chapters 20-20 through 20-24 and Division 3. This means that where a standard in this Section conflicts with a standard elsewhere in Title 20, the standard in this Section shall apply.
b. 
Projects not using the MMH Bonus entitlement shall be regulated by the standards of the primary zoning district and Division 3.
3. 
Applicability to Redevelopment of Existing Buildings. Redevelopment of existing structure(s) that results in at least two dwelling units and not more than 18 dwelling units per building may qualify for a MMH Bonus, subject to the standards pertaining to existing structures in Subsections C through E. Standards in this Section that would require exterior or interior demolition of the existing structure, in whole or in part, do not apply.
C. 
Missing Middle Housing Zones (MMH Zones).
1. 
Purpose. This Subsection provides zones and standards to implement the City of Santa Rosa's vision of enabling Missing Middle Housing.
2. 
Zones Overview. The -MMH combining district includes two MMH zones, each with one sub-zone. Table 2-18 provides an overview of each zone/sub-zone and its intent. This information is to describe the intended physical character and direction for the detailed standards in each zone. For further information, refer to Section 1.4 in the Guidance Document.[1]

3. 
MMH Zone Standards.
a. 
General Standards. Tables 2-19 through 2-23 contain standards applicable within the MMH zones.
b. 
Existing Structures. Standards for Building Placement (Table 2-20), Building Form (Table 2-21), and Vehicular and Bicycle Parking (Table 2-23) that would require exterior or interior demolition of the existing structure, in whole or in part, do not apply.
c. 
Design Sites. All new primary structures are required to use design sites in compliance with the standards in this Section.
1) 
Definition. A design site is a portion of land within a project site that is delineated from other design sites to accommodate a single primary structure or building type. Design sites are considered lots for the purpose of applying development standards, though legal subdivision is not required.
2) 
If only one primary structure is proposed, the lot and the design site are identical.
3) 
On an existing parcel whose width and/or depth do not meet the minimum design site dimensions for any building types allowed by the zone, any building type identified in Subsection D (Building Types) may be selected, provided that all other MMH zone standards and building type standards are satisfied.
4) 
Parcels with enough land area to accommodate multiple primary structures can have multiple design sites—see Subsection C.5 (Multiple Building Site Design).
d. 
Building Types and Frontage Types. From the allowed types in the MMH zone, and in compliance with the listed standards, the following shall be selected for each design site:
1) 
Only one primary building type per design site, except that an Accessory Dwelling Unit/Junior Accessory Dwelling Unit, in compliance with Section 20-42.130 (Accessory dwelling units), may be included within a design site in addition to the primary building type; and
2) 
One frontage type for each primary entrance to a building or unit.
e. 
Building types and frontage types not identified in the MMH zone's standards are not allowed in that zone.
f. 
Allowed Uses. Uses shall comply with the allowable uses for the primary zoning district established by Section 20-20.020 (Zoning Map and zoning districts), except that multifamily dwellings in compliance with this Section shall be permitted in any residential or mixed-use zoning district. Standards for individual building types and frontage types regulate physical form only and impose no additional limitations on allowed uses.
g. 
Fences. For the purposes of this Section, the term "fence" includes fences, hedges, walls or structures in the nature of a fence.
1) 
On design sites containing multifamily dwellings that comply with the building type standards of Subsection D (Building Types), fences are allowed subject to the standards given for single-family dwellings in Section 20-30.060 (Fences, walls, and screening) and the height allowances in Table 3-1 (Maximum Height of Fences).
2) 
All other standards in Section 20-30.060 (Fences, walls, and screening) shall apply.

4. 
Multiple Building Site Design.
a. 
Purpose. The purpose of this Subsection is to establish site planning standards for projects which include multiple primary structures. These standards help ensure a pattern of walkable development that maintains consistency of form and scale between new development and existing neighborhoods.
b. 
Applicability. The standards of this Subsection apply to any project which proposes more than one primary structure.
c. 
Sites of Four Acres or More. Parcels of four acres or more shall be designed according to the standards provided in Subsection F (Requirements for Sites of Four Acres or More). For more information and for an example of how these standards are applied, see Section 4.2 (Designing Large Sites as Walkable Neighborhoods) in the Guidance Document.
d. 
Design Sites for Multiple Primary Structures. If more than one primary structure is proposed on an existing parcel, design sites shall be used to organize the project site, according to the standards in Subsection 20-28.100.C.5.e (Lots and the Configuration of Design Sites). For more information and for an example of how design sites are applied, see Section 4.1 (Design Sites for Multiple Buildings) in the Guidance Document.
1) 
Exception: An existing parcel 100 feet or less in width along the street frontage and at least 175 feet deep that is not a corner lot, reverse corner lot, or through lot—see Figure 7-1 (Lot Types) in Section 20-70.020 for more information on identifying lot types—may include more than one building type without using design sites to organize the project site, if all of the following standards are met:
(a) 
New primary structures shall be arranged around a common space that accommodates both vehicles and pedestrians—see Figure 2-23 (Multiple Buildings on a Lot Without Design Sites).
(b) 
Primary entrance(s) to the building(s) closest to the street shall orient toward and be accessed from the street (see Figure 2-23).
(c) 
Each primary entrance shall include a frontage type meeting the standards provided in Subsection E (Frontage Types).
(d) 
At least 50% of the ground floor space of each building shall be habitable.
(e) 
The area between all habitable space and the pavement of the common space shall be landscaped, averaging at least 2 feet in width along each facade.
(f) 
Pavement surfaces may be stamped concrete, pavers, brick, and/or grasscrete. No more than 20% of the surface area may be asphalt or untextured concrete.

Lots and the Configuration of Design Sites.
1) 
Legal Status and Ownership. Design sites provide a way of organizing multiple primary units on a single development site and may either remain under single ownership, be subject to a condominium agreement, or be subdivided and sold as individual lots.
2) 
Public Realm. Elements constituting the public realm may be either publicly or privately owned but must be accessible to the public between the hours of 7 AM and 9 PM, 7 days a week. For the purposes of this Section, the public realm consists of any of the following elements:
(a) 
Existing rights-of-way, not including alleys or driveways;
(b) 
Existing public park(s) and/or civic space(s);
(c) 
Thoroughfare types identified in Subsection H (Thoroughfare Types), not including alleys or driveways; and/or
(d) 
Civic space types identified in Subsection G (Civic Space Types).
3) 
The public realm determines where design sites may be located. Design site(s) that do not front onto the public right-of-way shall front onto extension(s) of the public realm into the project site. See the sidebar on p. 55 of the Guidance Document (Example Applications of Design Sites) for an explanation of this technique. For an example of how new thoroughfares and civic space may be used to organize a site, see the sidebar on p. 57 of the Guidance Document (Example Application of Walkable Neighborhood Design Standards).
(a) 
Each design site shall abut the public realm along the front design site line;
(b) 
The side and/or side street design site line(s) shall abut the public realm, an alley or driveway, or another design site;
(c) 
The rear design site line(s) shall abut an alley, driveway or another design site.
D. 
Building Types.
1. 
Purpose. This Subsection provides the standards for development of individual building types to achieve the intended physical character of each zone, offering a greater range of housing choices, unit sizes, and price points within walkable neighborhoods. Building types are used to articulate size, scale, and intensity according to the intent of each zone. For more information, see Chapter 2 (Building Types) in the Guidance Document.
2. 
Applicability. The standards of Subsection D (Building Types) apply to new buildings and additions using the MMH Bonus entitlement for the purpose of allowing the proposed total number of dwelling units.
a. 
Existing Structures.
1) 
If the existing structure's height, Main Body, and/or Wing(s) exceed the maximum dimensions given for the selected building type, the maximum dimensions shall not apply, provided that no additional height is added and no additional square footage is added to the Main Body footprint. Wing(s) may be added up to the full dimensions given for Wings, as allowed by the building type and setback standards.
2) 
Primary Entrance Location standards for the selected building type shall not apply to existing primary entrances.
3) 
Minimum open space dimensions do not apply to existing structures.
3. 
General Standards.
a. 
Each design site shall have only one primary building type. Standards for multiple primary structures on a site are provided as follows:
1) 
The Cottage Court building type may consist of up to nine individual buildings. See Table 2-26—Cottage Court;
2) 
More than one building type is allowed on a parcel that identifies multiple proposed design sites that meet the standards of this Section, or which meets the exception criteria under Subsection 20-28.100.C.5.d.1. See Subsection 20-28.100.C.5 (Multiple Building Site Design).
b. 
The maximum number of units identified for each building type is subject to the design site's capacity to comply with all applicable standards. The maximum listed unit count may not be achievable on all design sites.
c. 
Main Body and Wings.
1) 
A Main Body is required for each building type. Wings are optional for the building types for which Wing standards are provided.
2) 
An internal connection is allowed but not required between the Main Body and Wing(s).
3) 
Separation between Wings applies only between Wings of the same building, not between adjacent design sites.
d. 
On-Site Open Space. Open space shall be provided on the design site for each building type according to the open space type (private or common) and amount indicated. The identified amount is for the entire building type unless otherwise specified. Open space types not listed are not required for that building type.
e. 
Individual building designs may vary from the diagrams for each building type in compliance with the standards of this Section.
f. 
New buildings and their improvements are subject to the City's local standards for Fire Safety and Building Safety.
