In addition to the purpose outlined in Section 18.02.020, the residential zones are included in the zoning regulations to achieve the following objectives:
A. 
To reserve appropriately located areas for family living at a broad range of dwelling unit densities consistent with the General Plan and with sound standards of public health, safety and welfare.
B. 
To ensure adequate light, air, privacy and open space for each dwelling.
C. 
To minimize traffic congestion and to avoid the overloading of utilities by preventing the construction of buildings of excessive bulk or number in relation to the land area around them.
D. 
To protect residential properties from noise, illumination, unsightliness, odors, smoke and other objectionable influences.
E. 
To facilitate the provision of utility services and other public facilities commensurate with anticipated population, dwelling unit densities, and service requirements.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for general agricultural purposes and low density residential uses with a minimum lot size of one acre and maximum density of one unit per acre. Only those additional uses are permitted that are complementary to, can exist in harmony with, an agricultural residential neighborhood. The areas included within this land use designation are characterized by large lots, and may consist of large rural estates with abundant open space on each lot, or large parcels devoted to commercial or non-commercial agriculture and/or grazing, which may have a residence and other accessory buildings such as barns, equipment sheds, and other similar buildings. The district also includes the keeping of equine, clefthoofed and other animals either as accessory to a residential use, or as the primary use, such as an equestrian center. Farms, ranches, and wholesale nurseries as well as single family residential, are all permitted uses within the R-A zone.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for low-density residential use with a minimum lot size of 39,000 square feet and maximum density of one unit per acre. Only those additional uses are permitted that are complementary to, and can exist in harmony with, low-density neighborhoods. Large estate and equestrian-oriented estates are characteristic uses within the RLD zone. The residential neighborhoods within this zone district are usually characterized by ample setbacks, and may include agricultural or other agrarian uses such as commercial farms or ranches, wholesale nurseries, and the keeping of equine or cleft-hoofed animals, although the RLD zone tends to be more residentially oriented than the R-A zone district.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for residential estates with minimum lot sizes of 15,000 square feet and maximum densities of 1.8 units per acre. Only those additional uses are permitted that are complementary to, and can exist in harmony with, a residential neighborhood. While agrarian uses and the keeping of equine, cleft-hoofed and other animals is permitted in this zone district, these uses are clearly incidental and accessory to the primary single-family residential use. Residential areas within the R-E zone are characterized by large, custom and semi-custom homes.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for suburban residential development on minimum lot sizes of 10,000 square feet and maximum densities of three units per acre. Only those additional uses are permitted that are complementary to, and can exist in harmony with, a residential neighborhood. The homes in the R-S zone district neighborhoods, while not necessarily custom, are individually constructed, often have the appearance of custom homes and are located on large lots.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for urban residential development on minimum lot sizes of 7,500 square feet and maximum densities of four units per acre. Only those additional uses are permitted that are complementary to, and can exist in harmony with, a residential neighborhood. Homes within the R-U zone are characterized as tract construction with entire neighborhoods built in the same time period. While individual homes may appear the same as those constructed in the R-S zone, the R-U zone dwellings are on smaller lots, giving the appearance of a slightly denser neighborhood. Some R-U zone neighborhoods have been constructed as "townhouse" units, which share common walls, but are located on individual lots, often with small rear yards, and/or front and rear courtyards.
(Ord. 2004-884; Ord. 2019-1056 § 3)
This zone is intended as an area for the development of garden apartments with provisions for adequate light, air, open space and landscaped areas at maximum densities of 10 units per acre. The required minimum lot size is 7,500 square feet. Only those additional uses are permitted that are complementary to, and can exist in harmony with, such residential developments. In addition to garden apartments, the R-M zone permits construction of clustered single-family dwellings, townhouses and, in some cases, stacked condominiums. In the latter examples, residential neighborhoods are characterized with common open areas and homeowner park and recreational facilities, such as swimming pools, tennis courts and clubhouses.
(Ord. 2004-884; Ord. 2011-968 § 2; Ord. 2019-1056 § 3)
This district is intended to promote the development of multi-family rental as well as ownership dwelling units up to 20 units per acre. The required minimum lot size is one acre. Permitted uses include cluster homes, townhouses, rowhouses, triplexes, fourplexes, apartments, stacked condominiums, and group housing. RM-20 residential neighborhoods are characterized as either individually owned or as rental units. Attached units include common open areas and recreational facilities, such as swimming pools, tennis courts and clubhouses.
(Ord. 2011-968 § 3; Ord. 2019-1056 § 3)
The purpose of the Multi-Family Residential district, also known as the R-M-30 district, is to provide space for multiple family residential developments commonly found in a dense urban environment. The R-M-30 district is intended for intensive residential uses up to 30 dwelling units per acre at readily accessible urban locations. With the exception of the Yorba Linda Water District (YLWD) Site, located at 4622 Plumosa Drive, the required minimum lot size is one acre. Permitted uses include apartments, stacked condominiums, studios, and group housing. R-M-30 residential neighborhoods are characterized as either individually owned or as rental units with common open areas and homeowner park and recreational facilities, such as swimming pools, tennis courts and clubhouses.
(Ord. 2011-968 § 4; Ord. 2019-1056 § 3)
Table 18.10-01 contains a listing of permitted uses and accessory uses within the various residential zones. Uses in the table are permitted subject to the permit criteria referenced. Any use not included shall be considered prohibited.

Transitional and supportive housing are permitted in residential zoning districts subject to the same standards as similar residential uses. Thus, if transitional or supportive housing is configured as a multi-family structure it would be regulated as such, WHEREAS if it is configured as a single-family structure, it would be subject to single-family regulations.

NOTES:
1
Any legally established lot that is at least 4,000 sq. ft. and has a minimum 20-foot-wide vehicular access to a street may be used as a building site.
2
Steeples, crosses and other religious symbols on churches and religious institutions may exceed the height limit in accordance with Section 18.24.110. See also Section 18.10.110.H and Section 18.26.030 of the Zoning Code for additional design standards related to height determinations for structures.
3
Side yard setbacks in R-A, RLD and R-E zones shall be 10 percent of the lot width, but not less than 10 feet, and need be no more than 20 feet.
4
Interior side yard setbacks in R-U and R-M, R-M-20, and R-M-30 zones shall have a cumulative total of both side yards of 20 feet; however, in no case shall a side yard be less than five feet.
5
Front yard setback requirements shall be applied to all property frontages facing public streets for the R-M, R-M-20, and R-M-30 zones.
6
The required 10-foot building separation standard shall not apply to small accessory structures as defined in Section 18.10.120.B. However, if the combined area of multiple small accessory structures located within three feet of each other exceeds a combined 120 square feet, each structure shall be considered a large accessory structure.
7
Residential properties having a slope gradient of 15 percent or greater shall comply with the regulations contained in Chapter 18.30 of this title.
(Ord. 2004-884; Ord. 2011-968 § 6; Ord. 2014-1005 § 5; Ord. 2014-1011 § 5; Ord. 2019-1056 § 3; Ord. 2024-1111, 7/16/2024)
A. 
Setbacks. In addition to those setbacks set forth in Table 18.10-02, the following additional requirements shall apply:
1. 
Buildings Exceeding 15 Feet in Height. In any R-M zone, any building exceeding 15 feet in height shall maintain a minimum setback of 50 feet from any single-family zone: any building less than 15 feet in height shall maintain a minimum setback of 20 feet from any single-family zone.
2. 
Public or Semi-Public Uses. In any residential zone, public or semi-public uses shall maintain a setback of 50 feet from an adjacent residential property line.
3. 
Front Setback Averaging. In any residential zone, front yard setbacks in subdivision developments may be reduced by 25 percent on individual lots provided the average of all setbacks in the development is not less than the minimum required for the zone.
4. 
Setback from Active Railroad Track. In any residential zone, the dwelling structure shall maintain a minimum distance of 225 feet from any active railroad track.
5. 
A minimum setback of five feet shall be maintained for any structure from any driveway, trail or ingress-egress easement, except that a minimum setback of 25 feet shall be maintained from a public trail for any habitable multiple-family dwelling. Exceptions may be approved by the Planning Commission during Design Review.
6. 
Projections. Porches, steps, architectural features, such as eaves, awnings, chimneys, balconies, exterior stairways, wing walls, elevator shafts or bay windows may project not more than four feet into any required front or rear yard area, nor into any required side yard area more than one-half of said required side yard.
7. 
When the property contains a City trail, landscape, open space, recreational or similar easement, or a private street easement, the reference point for determining setback distance shall be the edge of the City easement or private street easement, unless, based on the configuration of the City easement or private street easement, or other circumstance, an alternate point of reference is determined appropriate by the Community Development Director.
B. 
Two-Story Buildings/Additions. In any residential zone, a two-story building or two-story room addition closer than 70 feet to an existing single-family residence shall require that a conditional use permit be approved by the Planning Commission or Zoning Administrator, per the requirements of Chapter 18.38, prior to the issuance of a building permit. The 70 feet shall be measured from the edge of any new two-story construction to the closest edge of any existing single-family residence exclusive of the garage. When reviewing a second story room addition application, the Planning Commission or Zoning Administrator shall make the mandatory findings as follows:
1. 
That the two-story construction does not result in any significant loss of privacy for adjacent residences in a manner that would compromise the neighbors' ability to obtain reasonable and enjoyable use of their own property.
2. 
For a building addition, that the design of the two-story construction be architecturally integrated with that of the existing house as to be made to appear as part of the original construction.
3. 
That the design of the structure is sensitive to its environs such that it is architecturally compatible with the neighborhood.
4. 
For any second story addition to any attached single-family structure, the Planning Commission or Zoning Administrator shall encourage construction which has the least impact on the neighboring attached dwelling unit and which is most structurally sound.
Figure 18.10-1 Sample Residential Lot Plan
C. 
Parking. In any residential zone, parking of motor vehicles shall be subject to the requirements of the Sample Residential Lot Plan (Figure 18.10-1) and subject to the following:
1. 
No vehicle, boat, or trailer may be parked in the front yard, except on paved driveways. The parking of vehicles elsewhere on a residential lot is prohibited unless the vehicle is enclosed within a building or kept under a carport in a lawful manner, or parked on a fenced side or rear yard area on a paved surface and in a manner that eliminates or reduces visibility of the vehicle from surrounding properties or streets to the greatest extent feasible. Acceptable screening methods shall include solid walls and fencing, landscaping, etc., as determined by the Community Development Director.
2. 
The parking of any inoperable, wrecked or dismantled vehicle on a residential property is prohibited, except as provided in Chapter 8.08 of the Yorba Linda Municipal Code.
3. 
The parking of any Class 5 truck (based on gross vehicle weight rating) or larger, or any other similar commercial vehicle, including special equipment and truck-tractors, in or on any part of residentially-zoned property is prohibited except as is reasonably necessary to pick up or deliver goods, wares, or merchandise from or to any structure located in such zone, or for such time as is reasonably necessary for the purpose of delivering materials to be used in the actual repair, alteration, remodeling, or construction of any building or structure in such zone for which a building permit has previously been obtained from the City.
4. 
Recreational Vehicle Parking. Recreational vehicles, including motorhomes, boats, trailers and other similar vehicles, may be stored on any residential zoned property which is developed as single-family detached, subject to the following standards (See Figure 18.10-1):
a. 
The vehicle shall be parked on a paved surface.
b. 
If parked in the front yard setback, the vehicle shall be parked at a perpendicular angle to the street, including those vehicles parked on circular drives, or driveways heading to side-entry garages.
c. 
If parked in side yards, the vehicle shall be placed behind a six-foot high solid wall or fence, including six-foot high solid gate(s).
d. 
No vehicle shall be parked or stored in street side yards of corner lots.
e. 
No parked or stored vehicle shall encroach into the public right-of-way or onto any public or private access drive, street or pedestrian walkway.
f. 
The parking of recreational vehicles shall be limited to only those vehicles that are owned by the property owner and/or tenant residing on the property.
Figure 18.10-2 RV Parking
5. 
As depicted in Figure 18.10-3, driveway curb cuts for single-family detached residential units shall be limited to one such curb cut leading to a garage or carport, or an accessory dwelling unit legally converted from an existing garage or carport in accordance with Article 11 of Chapter 18.20, with the exception that one additional curb cut may be provided where a circular driveway is provided, or in other appropriate cases, and subject to the approval of the Community Development Director and City Engineer. All driveway surfaces shall be paved, surfaced in concrete cement or other permanent material, as approved by the Community Development Director.
6. 
The minimum driveway width shall be 16 feet; however, flag lots shall maintain a minimum driveway width of 20 feet. The Community Development Director, in consultation with the Fire Marshall, may authorize a narrower driveway width under certain circumstances, including, but not limited to, when secondary access is provided, or when other mitigating factors make the minimum driveway width unnecessary.
Figure 18.10-3 Driveway Types
D. 
Manufactured Homes. Any manufactured home which is certified under the National Manufactured Housing Construction and Safety Standards Act of 1974 is permitted on any lot within any residential zone, providing the following criteria are met:
1. 
The application shall be reviewed in accordance with the design review provisions of Section 18.36.100 of this title.
2. 
The structure shall comply with all setback, height and other property development standards of the zone in which it is placed.
3. 
The manufactured home shall be placed on a solid concrete or masonry foundation.
4. 
The exterior siding shall be wood or other material customarily used in conventionally built single-family dwellings.
5. 
Roofs shall be in compliance with the City Building Code and shall consist of fire-retardant composition shingles or tile, and roof pitch shall be similar to those roofs of the same material on conventionally built single-family dwellings in the neighborhood, but in no case shall roof pitch be less than a ratio of 3:12.
6. 
Roofs shall have eave and gable-end overhangs of not less than 12 inches.
7. 
Carports or garages with the same dimensions and number of spaces shall be provided in accordance with Chapter 18.22 and Section 18.10.090 of this chapter.
E. 
In any RM zone, PD zone allowing multi-family uses, or any overlay zone, the City of Yorba Linda Multi-Family Residential Design Guidelines shall be utilized as additional objective development standards for multi-family development in producing high-quality development.
(Ord. 2004-884; Ord. 2019-1056 § 3; Ord. 2020-1074 § 4; Ord. 2024-1110, 7/16/2024)
A. 
Mechanical Equipment. In all residential zones, air conditioners, pool equipment, heating, cooling, ventilating equipment and all other mechanical devices shall not be located within the required street side yard (unless screened by a solid block wall or fence) or front yard. Such equipment shall be located at least 15 feet from any habitable opening of a structure on an adjacent property, and shall be so operated that they do not disturb the peace, quiet and comfort of neighboring residents and shall be screened from surrounding properties and streets per Section 18.26.080 of this title. Additionally, all such equipment shall be installed and operated in accordance with the noise ordinance (Chapter 8.32, Noise Control) of the City Municipal Code and with all other applicable ordinances and regulations. Deviations to the locational requirements of this subsection may be approved with an Administrative Adjustment in accordance with Section 18.38.070.
B. 
Lighting. All light fixtures, except street lamps, shall be aimed or shielded so that direct illumination is confined to the property boundaries of the source. Particular care shall be taken to ensure that direct illumination does not spill onto or across any public or private street or road, or adjacent property. To reduce glare disturbance, light fixtures shall be designed such that direct views of luminaires from off site are minimized. For security lighting, motion sensing lighting fixtures are encouraged, and shall be properly adjusted, according to the manufacturer's instructions, to turn off when detected motion ceases. Exceptions to this provision are:
1. 
Seasonal holiday lighting between Thanksgiving Day and January 15th;
2. 
No more than 14 additional days in any given calendar year for any other seasonal holiday lighting as approved by the Community Development Director; and
3. 
Any lighting approved by the Planning Commission as a part of a conditional use permit process.
C. 
Landscaping.
1. 
In all residential zones, front and street side yards shall be landscaped and shall consist of a minimum of 51 percent of plant materials except for necessary walks, drives and fences. For newly constructed homes, the front and street side yard landscaping shall be installed within 12 months from the date of the issuance of final certificate of occupancy.

A. 
Habitable accessory structures shall meet the setbacks required for main buildings. For the purposes of this subsection, classification of an accessory structure as habitable shall include structures with heating, sleeping, living or cooking facilities, unless the Community Development Director determines that the accessory structure is clearly not intended to be used for sleeping unit or dwelling unit purposes.
B. 
Small accessory structures (e.g., gardening and tool sheds) which are single-story and not greater than eight feet in height, or greater than 120 square feet in area, shall maintain required setback for the main building within the front yard area, and shall maintain a minimum five-foot setback on a side or rear yard adjacent to a street, or from a City landscape easement. Within an interior side or rear yard area, a minimum three-foot setback shall be provided, unless one-hour fire construction is provided in which case no setback shall be required. If greater than eight feet in height or 120 square feet in area, then required setbacks for larger accessory structures shall apply as stipulated in subsection C or D below, as applicable, depending on the size and height of the structure. Shipping containers are specifically prohibited in any residential zone.
The Community Development Director shall determine whether minor decorative landscape features and structures, such as small benches, statues, light posts, bird baths, fountains, or arbors, shall be subject to the front yard setbacks required for main buildings. This determination shall be made based on the size and type of structure, taking into account whether or not a particular structure falls within the category of structures that generally are considered customary or appropriate within a typical residential front yard landscape/hardscape design.
C. 
Large accessory structures (e.g., non-habitable garages, barns, cabañas, game rooms, etc.), which are single-story and not greater than 15 feet in height, or greater than 1,000 square feet in area, shall maintain the required setback for the main building within the front yard area, and shall maintain a minimum 10-foot setback on a side or rear yard adjacent to a street. Within interior side or rear yard areas, a minimum five-foot setback shall be provided. Shipping containers are specifically prohibited in any residential zone. Furthermore, the following standards shall apply:
1. 
The required five-foot setback for outdoor fireplaces shall be measured from the nearest edge of the stack portion of the fireplace at the height of the property line wall or fence to the nearest portion of the property line. The entire structure shall maintain a minimum three-foot setback from the property line and must comply with the Section R302.1 of the California Residential Code (see Figure 18.10-4).
Figure 18.10-4 Outdoor Fireplace Setback
2. 
The required five-foot setback for water slides and waterfalls shall be measured from the nearest edge of the water slide/waterfall at the height of the property line wall or fence to the nearest portion of the property line. The entire structure shall maintain a minimum three-foot setback from the property line and must comply with Section R302.1 of the California Residential Code and Section 3109 of the California Building Code (see Figure 18.10-5).
Figure 18.10-5 Waterslide/Water Fall Setback
D. 
Two-story accessory structures, and one-story accessory structures greater than 15 feet in height or 1,000 square feet in area, shall meet the setbacks required for main buildings, with the exception that such structures in RA and RLD zones may maintain a 25-foot rear yard setback. The provisions of Section 18.10.100.B shall apply to two-story structures where applicable. Shipping containers are specifically prohibited in any residential zone.
E. 
Architectural Design Standards. Accessory structures classified pursuant to subsections A, C and D of this section shall also adhere to the following design criteria:
1. 
The structure shall be designed to create a unified, functional and comprehensive site plan with an integrated architectural theme that is compatible with and will complement and enhance the subject and surrounding properties.
2. 
With the intent of protecting sensitive land uses, and preserving the aesthetic quality of the street scene, the proposed design shall promote a harmonious and compatible transition in terms of scale and character between the subject property and adjoining properties, and the street. Design considerations in this regard include, but shall not be limited to, roof design, height, slope and materials, window location and treatment, exterior wall cladding, and landscaping.
The Community Development Director shall determine conformance with the foregoing design criteria.
F. 
Landscaping Required. Accessory structures that side or rear along a City landscape easement or a street shall provide screen landscaping within the setback area as approved by the Community Development Director. The type, amount, size and location of landscaping shall be sufficient to adequately diffuse visibility of the structure(s) as seen from the street to prevent degradation of the overall visual quality of the roadway.
G. 
Setbacks When Slope Present. When a side or rear yard contains a slope down to a street, and the property line is located somewhere other than at the top of the slope, the reference point for determining accessory structure setback distance shall be the top of the slope, unless, based on the configuration of the slope, or other circumstance, an alternate point of reference is determined appropriate by the Community Development Director.
H. 
Deviations. Accessory structures that do not conform to the requirements of subsection C or D may be approved by the Planning Commission, subject to the granting of a conditional use permit. Minor deviations may be approved by the Zoning Administrator subject to the requirements of Section 18.38.070 of this title.
I. 
Canopies, patio covers and other similar roofed structures, either freestanding or attached to the main building, or connecting the main building with a detached accessory building shall meet the setbacks for the main structure within the required front and street side yards, but may extend into a required rear or interior side yard provided that portions of such structures extending into the yard:
1. 
Shall not exceed 12 feet in height or project closer than three feet from an interior side or rear property line. Taller structures up to 15 feet in height may be permitted based on, but not limited to, building design, roof slope and design, location, topography or other criteria and subject to approval by the Community Development Director.
Any two-story gazebo, palapa, pavilion, or similar open-air canopy structure, any second story deck/balcony addition, including landings and stairs, or any single-story canopy structure that is 24 feet in height or higher shall require the approval of a conditional use permit by the Zoning Administrator prior to construction.
A conditional use permit shall not apply to detached ground-level decks which cantilever over a slope when the finished floor height does not exceed nine feet above grade at the point with the greatest vertical distance between finished floor and grade.
In addition to consideration of building design, massing, roof slope and design, location, topography or other criteria, in evaluating such structures, the Zoning Administrator shall take into consideration the potential for undue impact to privacy on adjoining properties. Single-story structures, greater than 15 feet in height or two-story structures shall meet the setbacks for the main building.
2. 
Shall be entirely open on at least three sides except for necessary supporting columns: except that a roof connecting a main building and an accessory building shall be open on two sides.
Car tents and other similar temporary sheltering devices are not considered a canopy or patio cover. Such devices shall not be permitted in any areas between property lines abutting streets and the main structure. Furthermore, such structures shall not exceed 12 feet in height and shall provide a minimum five-foot setback from interior side or rear property lines. (See Figure 18.10-6).
Figure 18.10-6 Prohibited Areas for Car Tents
J. 
Patio Enclosures/Sun Rooms. A patio enclosure/sun room is a solid roofed structure that has a maximum height of 12 feet with at least two side walls having 65 percent or greater screened openable area. Openable area means readily removable windows. The interior space shall not be temperature controlled by mechanical means for either heating or cooling. Qualifying structures may encroach no more than 50 percent into the required rear yard setback of the main building for that zone district. All patio enclosures/sun rooms built prior to the effective date of the ordinance codified in this title with valid building permits that exceed this maximum encroachment standard shall be construed as legally nonconforming structures.
(Ord. 2004-884; Ord. 2005-887; Ord. 2009-937 § 3; Ord. 2019-1056 § 3)
A. 
A wall or fence shall not exceed 36 inches in height for any portion of the required front yard located directly in front of the dwelling and for a width equal to the minimum lot width for the zone; however, the Community Development Director may approve minor increases in height up to 42 inches for decorative elements, such as pilasters, after review by the City Traffic Engineer. All other portions of the required front yard may have a wrought iron fence not exceeding five feet in height or a combination five-foot-high masonry and wrought iron, where the masonry portion does not exceed three feet in height. In order to fence or wall in the required front yard to exceed these requirements, a conditional use permit shall be approved by the Planning Commission after review by the City Traffic Engineer (see Figure 18.10-7).
B. 
A wall or fence not more than six feet in height may be maintained along a side or rear property line provided it is not adjacent to a public street, and further provided that such wall or fence does not extend into the required front yard (see Figure 18.10-7). The Community Development Director may approve minor adjustments to fence height to ensure pool-safe barrier compliance without the need for formal review of an administrative adjustment or variance application.
Figure 18.10-7 Fences and Walls
C. 
A wall or fence adjacent to any public street shall be set back a minimum of five feet from the street-abutting side or rear property lines. The Community Development Director may approve deviations from this standard based on property line location, topography or other unique site conditions. Any deviation shall be provided in writing. The area between the fence and the property line shall be landscaped and maintained by the property owner.
The Community Development Director may administratively approve a deviation of 10 percent or less to the provisions contained in subsections A and B above. A deviation of 11 percent to 20 percent over the prescribed standards contained in subsections A and B above, and/or retaining walls and/or combination retaining and screen walls up to a maximum height of nine feet may be approved subject to the granting of an administrative adjustment in accordance with the provisions of Chapter 18.38 of this title. The Community Development Director shall have the authority to administratively approve walls and fences that comply with Section 18.26.090 of this title.
D. 
The height of any wall and/or fence shall be measured from the lowest side of the wall/fence, from finished grade to the top of said wall/fence at the point of measurement. Further, when a wall and/or fence immediately abuts another wall/fence, the measurement for determining wall height shall be measured from the lowest side of the wall/fence, from finished grade to the top of the highest abutting wall/fence at the point of measurement.
When a wall and/or fence is separated by at least three feet (see Figure 18.10-8), then each wall/fence shall be considered an independent structure and the measurement for determining wall/fence height shall be from finished grade to the top of each respective wall/fence at the point of measurement.
