City of Santa Rosa, CA Chapter 20-22 RESIDENTIAL ZONING DISTRICTS

§ 20-22.010 Purpose.

This chapter lists the land uses that may be allowed within the residential zoning districts established by Section 20-20.020 (Zoning Map and Zoning Districts), determines the type of land use permit/approval required for each use, and provides basic standards for site layout and building size.

(Ord. 3677 § 1, 2004; Ord. 3968 § 1, 2011)

§ 20-22.020 Purposes of the residential zoning districts.

The purposes of the individual residential zoning districts and the manner in which they are applied are as follows.

A. RR (Rural Residential) district. The RR zoning district is applied to areas of the City intended to accommodate residential neighborhoods with compatible agricultural uses, but where the primary uses are residential, and compatible accessory uses. The maximum allowable density ranges from 0.2 to two dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the RR map symbol (see Section 20-22.040). The RR zoning district implements and is consistent with the Residential—Very Low Density land use classification of the General Plan.

B. R-1 (Single-Family Residential) district. The R-1 zoning district is applied to areas of the City intended to be maintained as residential neighborhoods comprised of detached and attached single-family houses, clustered Residential hillside projects, and small multi-family projects, together with compatible accessory uses. The maximum allowable density ranges from two to 13 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-1 map symbol (see Section 20-22.040). The R-1 zoning district implements and is consistent with the Residential—Very Low Density (where residential clustered on hillsides is desirable), Low Density/Open Space, Low Density, and Medium Low Density land use classifications of the General Plan.

C. R-2 (Medium Density Multi-Family Residential) and R-3 (Multi-Family Residential) districts. The R-2 and R-3 zoning districts are applied to areas of the City appropriate for residential neighborhoods with medium and higher residential densities, to provide home rental and ownership opportunities, and to provide a full range of choices in housing types to improve access to affordable housing. The maximum allowable density ranges from eight to 30 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-3 map symbol (see Section 20-22.040). Densities of more than 30 dwellings per acre may be allowed within the Mixed Use land use designation of the General Plan. The R-2 and R-3 zoning districts implement and are consistent with the Residential—Medium Density and Medium High Density land use classifications of the General Plan.

D. TV-R (Transit Village-Residential) district. The TV-R zoning district is applied to areas within approximately one-half mile of a transit facility that is appropriate for mixed use development. Development should transition from less intense uses at the outlying edges to higher intensity uses near the transit facility. Residential uses are required, and ground floor neighborhood serving retail and live-work uses are encouraged. The maximum allowable density ranges from 25 to 40 dwellings per acre. The TV-R zoning district is consistent with and implements the Transit Village Medium land use classification of the General Plan.

E. MH (Mobile Home Park) district. The MH zoning district is applied to areas of the City occupied by and intended to be maintained as mobile home parks. The maximum allowable density ranges from four to 18 dwellings per acre. The MH zoning district implements and is consistent with the Residential—Mobile Home Park land use classification of the General Plan.

§ 20-22.040 Residential district subdivision and density standards.

The minimum parcel size requirements for new subdivisions in the residential zoning districts and maximum allowable residential densities are established by Table 2-3.

A. Application of requirements to property. The application of minimum parcel size requirements to property within the City is shown on the Zoning Map (Chapter 20-20) by means of a numerical or alphabetical suffix appended to the residential Zoning Map symbols (e.g., R-1-9, R-3-HD). Each applicable suffix is shown in the "Zoning District and Suffix" column of Table 2-3.

B. Attached housing projects. A condominium, townhome, or planned development project may be subdivided for ownership purposes into smaller parcels than allowed by Table 2-3, with the minimum lot area requirement, maximum lot coverage, and dimensions determined through the subdivision review process, provided that the overall development site complies with the lot area and width requirements of this Chapter, and the total number of dwellings does not exceed the maximum density established by the applicable zoning district.

C. Small lot residential projects. Small lot residential projects are allowed in compliance with Section 20-42.140 (Residential Small Lot Projects), instead of the requirements in Table 2-3.

MH	5 acres for mobile home park; as determined by mobile home park Conditional Use Permit for individual mobile home sites within a mobile home park.		4 to 18 units per acre
TV-R	None required.		25 to 40 units per acre (3)

Notes:
(1)	Minimum lot width shall be measured midway between the front and rear lot lines.
(2)	The density requirement is expressed as the minimum number of square feet of gross site area required for each dwelling unit.
(3)	A Missing Middle Housing development designed in accordance with Section 20-28.100 is not subject to the unit per square footage requirement.

D. Development in all R-3 and TV-R districts shall provide at least the midpoint of the allowed density, unless topography, parcel configuration, heritage trees, historic preservation, or utility constraints make the midpoint impossible to achieve.

(Ord. 3677 § 1, 2004; Ord. 3711 § 1 Exh. A, 2005; Ord. 3950 § 5, 2010; Ord. 2020-014 § 7; Ord. 2025-014, 11/18/2025)

§ 20-22.050 Residential district general development standards.

New land uses, structures, and site development, and alterations to existing land uses, structures, and site development within the residential zoning districts shall be designed, constructed, and established in compliance with the following re-quirements, and all applicable standards in Divisions 3 (Site Planning and General Development Standards) and 4 (Standards for Specific Land Uses) of this Zoning Code.

A. RR and R-1 zoning districts. See the requirements in Tables 2-3 and 2-4.

B. R-2 and R-3 zoning districts. See the requirements in Tables 2-3 and 2-5.

C. MH zoning district. See the requirements in Section 20-42.100 (Mobile Home Parks).

D. TV-R zoning district. See the requirements in Tables 2-3 and 2-5. The standards of this district are intended to support a diverse mix of multi-family housing, live-work housing and mixed-use residential with neighborhood serving retail. See also the General Plan, Downtown Station Area Specific Plan and Section 2 (Core Area) of the City's Design Guidelines.

1. Residential required. Each new development shall be a residential project, with a ground floor neighborhood serving retail or live-work component encouraged, in compliance with the residential density requirements of the TV zoning district in Table 2-3.

2. Height limit. There is a four-story height limit for new buildings within this zoning district, with the exception of those projects located adjacent to existing residential zones or residential uses where the maximum height shall transition down to a maximum of three stories adjacent to the residential property.

3. Development adjacent to residential zones and residential uses. Development located adjacent to a Residential zone or residential use shall be compatible in both scale and design with the adjacent neighborhood.

4. Site design, hours of operation. Site design and hours of operation shall be as determined by the review authority to be compatible with surrounding neighborhood uses.

5. Setbacks for noise and air quality impacts. To facilitate the planned transition to a more compact Development pattern within the TV-R zoning district, increased setback distances shall not be used as a measure to mitigate potential noise and air quality impacts when new development is proposed adjacent to nonconforming industrial or light industrial uses.

E. NMU zoning district. See the requirements in Tables 2-6 and 2-8. The standards of this district allow for new multi-family residential development and other neighborhood-scale supporting uses in all-residential or mixed-use buildings.

See also Sections 2 (Core Area), 3.1 (Single-Family Residential), 3.2 (Multiple-Family Residential), and 4.3 (Infill Development), of the City's Design Guidelines.
