For any lot designated as Public, Quasi-Public, Public/Quasi-Public Use, Other Public, or Open Space on the land use map of the applicable community or district plan; any lot shown on the map as having existing lakes, waterways, reservoirs, debris basins, or similar facilities; any lot shown on the map as the location of a freeway right-of-way; and any property annexed to the City of Los Angeles where a plan amendment was not adopted as part of the annexation proceedings:
Any of the uses permitted by Subsection A. of this section shall require prior approval in accordance with the provisions of Section 12.24.1 of this Code.
C. Area (Development Standards). No building or structure nor the enlargement of any building or structure shall be erected or maintained unless the following yards, lot areas, and floor area limitations are provided and maintained in connection with the building, structure, or enlargement: (Amended by Ord. No. 179,883, Eff. 6/29/08.)
1. Front Yard. There shall be a front yard of not less than 20% of the depth of the lot, but such front yard need not exceed 25 feet; provided, however, that where all of the developed lots which have front yards that vary in depth by not more than ten feet comprise 40% or more of the frontage, the minimum front yard depth shall be the average depth of the front yards of each such lot. Where there are two or more possible combinations of developed lots comprising 40% or more of the frontage, each of which has front yards that vary in depth by not more than ten feet, the minimum front yard depth shall be the average depth of the front yards of that combination which has the shallowest average depth. In determining the required front yard buildings located on key lots, entirely on the rear half of lots, or on lots in the “C” or “M” Zones, shall not be counted, provided, however, that nothing contained in this paragraph shall be deemed to require front yards which exceed 40 feet in depth. (Amended by Ord. No. 139,155, Eff. 10/16/69.)
On key lots the minimum front yard may be the average of the required front yard for the adjoining interior lot and the required side yard along the street side of a reversed corner lot, but such minimum front yard may apply for a distance of not more than 85 feet from the rear lot line of the reversed corner lot, beyond which point the front yard specified in the above paragraph shall apply. Where existing buildings on either or both of said adjoining lots are located nearer to the front or side lot lines than the yard required by this article, the yards established by such existing buildings may be used in computing the required front yard for a key lot.
2. Side Yards. (Amended by Ord. No. 169,775, Eff. 6/2/94.)
(a) RE9, RE11, RE15 Zones. On a lot in the RE9 or RE11 Zone, there shall be a side yard on each side of a main building of not less than five feet, except that, where the lot is less than 50 feet in width, the side yard may be reduced to ten percent of the width of the lot, but in no event less than three feet. On a lot designated RE15, there shall be a side yard on each side of a main building of not less than ten percent of the lot width, but in no event less than five feet, however, the side yard need not exceed ten feet.
Notwithstanding the above paragraph, on a lot in the RE9 or RE11 Zone which is not located in a Hillside Area or Coastal Zone, there shall be a side yard on each side of a main building of not less than seven feet, except that where the lot is less than 70 feet in width, the side yard may be reduced to ten percent of the width of the lot, but in no event to less than three feet.
(b) RE20, and RE40 Zones. On a lot in the RE20 or RE40 Zone, there shall be a side yard of not less than ten feet on each side of a main building.
(c) For a building more than two- stories in height, one-foot shall be added to the width of each required side yard for each additional story above the second story.
In lieu of the additional side yard requirement in the above paragraph, for new construction of a main building or a ground floor addition to the main building on a lot in the RE9, RE11, RE15, or RE20 Zone which is not located in a Hillside Area or Coastal Zone, if the main building exceeds 18 feet in height, then one-foot shall be added to the width of each required side yard for each increment of ten feet or fraction thereof above the first 18 feet of height of the main building.
(d) Side yard requirements in specific plans, Historic Preservation Overlay Zones or in subdivision approvals shall take precedence over this subdivision. This subdivision shall apply in these areas, however, when there are no such side yard requirements.
3. Rear Yard. There shall be a rear yard of not less than 25% of the depth of the lot, but such rear yard need not exceed 25 feet.
4. Lot Area. Every lot classified in the RE Zone is, according to the lot area requirements, further designated as RE9, RE11, RE15, RE20 or RE40. Where the Zoning Map shows only the designation RE, the land shall be considered as being classified as RE11, and the Zoning Map, heretofore made a part of Section 12.04 of this Code, is hereby amended to indicate said designation without additional procedure. (Amended by Ord. No. 137,892, Eff. 2/7/69.)
Every lot shall have a minimum width and area as follows:
[LOT SIZE “RE” ZONE]
(Amended by Ord No. 137,892, Eff. 2/7/69.)
[Zone] | Minimum Lot Width | Minimum Lot Area |
RE9 | 65 feet | 9,000 square feet |
RE11 | 70 feet | 11,000 square feet |
RE15 | 80 feet | 15,000 square feet |
RE20 | 80 feet | 20,000 square feet |
RE40 | 80 feet | 40,000 square feet |
The minimum lot area per dwelling unit shall be the same as the minimum lot area, except for two-family dwellings on lots having a side lot line adjoining a lot in a commercial or industrial Zone as provided for in Subsection A. of this section.
Provided, however, that on the property located within the RE Zone and also within an “H” Hillside or Mountainous Area for which a General Plan including dwelling unit densities has been adopted by the Council, the number of lots may be limited and the minimum area may be increased so that the number of dwelling units permitted will not substantially exceed the densities shown on the plan. (Amended by Ord. No. 141,821, Eff. 5/24/71.)
There may be lots with less than the minimum width and area, as provided by Section 17.05 H. of this Code, and there may be a single- family dwelling on each such lot if the lot is shown with a separate letter or lot number on a recorded Subdivision Tract Map or a Parcel Map. (Amended by Ord. No. 130,871, Eff. 9/20/65.)
Exceptions to area regulations are provided for in Sec. 12.22 C.
5. Maximum Residential Floor Area. (Amended by Ord. No. 184,802, Eff. 3/17/17.) For a lot located in a Hillside Area or Coastal Zone, the maximum Residential Floor Area shall comply with Section 12.21.1 A.1. of this Code.
For all other lots, the maximum Residential Floor Area contained in all buildings and accessory buildings shall be as follows: In the RE9 and RE11 Zones, the maximum Residential Floor Area shall be 40 percent of the lot area when the lot is less than 15,000 square feet. For lots 15,000 square feet or greater in the RE9 and RE11 Zones, the maximum Residential Floor Area shall be 35 percent of the lot area or 6,000 square feet, whichever is greater. For lots in the RE15, RE20 and RE40 Zones, the maximum Residential Floor Area shall be 35 percent of the lot area.
An additional 20 percent of the maximum Residential Floor Area for that lot shall be allowed if any of the methods listed below are utilized. Only one 20 percent bonus per property is allowed.
(a) The total Residential Floor Area of each story other than the base floor in a multi-story building does not exceed 75 percent of the base floor area; or
(b) The cumulative length of the exterior walls facing the front lot line, equal to a minimum of 25 percent of the building width shall be stepped-back a distance of at least 20 percent of the building depth from a plane parallel to the lot width established at the point of the building closest to the front lot line. When the front lot line is not straight, a line connecting the points where the side lot lines and the front lot line intersect shall be used. When through-lots have two front yards, the step-back shall be provided along both front lot lines.
For the purposes of this provision, all exterior walls that intersect a plane parallel to the front lot line at 45 degrees or less shall be considered to be facing the front lot line. The building width shall be the greatest distance between the exterior walls of the building measured parallel to the lot width. The building depth shall be the greatest distance between the exterior walls of the building measured parallel to the lot depth.
6. Verification of Existing Residential Floor Area. (Amended by Ord. No. 184,802, Eff. 3/17/17.) For additions with cumulative Residential Floor Area of less than 1,000 square feet constructed after January 1, 2008, or remodels of buildings built prior to January 1, 2008, the existing Residential Floor Area shall be determined based on the building records or the building square footage shown on the most recent Los Angeles County Tax Assessor’s records at the time the plans are submitted to the Department of Building and Safety and a plan check fee is paid. Except that Residential Floor Area may be calculated as defined in Section 12.03 of this Code when a complete set of fully dimensioned plans with area calculations of all the structures on the lot, prepared by a licensed architect or engineer, is submitted by the applicant.
Any work that does not qualify as a remodel, as defined in the paragraph below, or additions that are 1,000 square feet or larger shall require a complete set of fully dimensioned plans with area calculations of all the structures on the lot prepared by a licensed architect or engineer.
For the purposes of implementing this subdivision, a remodel shall mean the alteration of an existing building or structure provided that at least 50 percent of the perimeter length of the contiguous exterior walls and 50 percent of the roof are retained.
The following regulations shall apply in the “RS” Suburban Zone:
A. Use — No building, structure or land shall be used and no building or structure shall be erected, structurally altered, enlarged, or maintained, except for the following uses, and when a “Supplemental Use District” is created by the provisions of Article 3 of this chapter, for such uses as may be permitted therein:

All portions of a building that have a side wall exceeding 14 feet in height and a continuous length greater than 45 feet shall have an offset/plane break that is a minimum depth of five feet beyond the required yard and a minimum length of 10 feet. For the purpose of this Subdivision, height shall be measured from the existing or finished grade, whichever is lower, at each point along the perimeter of the building.
(b) In lieu of the additional one-foot side yard for each story above the second story as required above, for new construction of a main building or a ground floor addition to the main building on a lot not located in a Hillside Area or Coastal Zone, one-foot shall be added to each required side yard for each increment of ten feet or fraction thereof above the first 18 feet.
(c) Side yard requirements in specific plans, Historic Preservation Overlay Zones or in subdivision approvals shall take precedence over this subdivision. This subdivision shall apply in these areas, however, when there are no such side yard requirements.
(d) Any occupied rooftop deck shall be set back at least three feet from the minimum required side yard. This provision shall not apply to any rooftop deck located on the street side of a Corner Lot.
3. Rear Yard. There shall be a rear yard of not less than 15 feet in depth. (Amended by Ord. No. 121,925, Eff. 6/4/62.)
4. Lot Area. (Amended by Ord. No. 153,478, Eff. 4/12/80.). Every lot shall have a minimum width of 50 feet and a minimum area of 5,000 square feet. The minimum lot area per dwelling unit shall also be 5,000 square feet, except for two-family dwellings on lots having a side lot line adjoining a lot in a commercial or industrial zone as provided for in Subsection A. of this section.
There may be lots with less than the minimum required area and there may be a single dwelling on each such lot if the lot is shown with a separate letter or lot number on a recorded Subdivision Tract Map or a Parcel Map.
5. Maximum Residential Floor Area and Massing. (Amended by Ord. No. 184,802, Eff. 3/17/17.)
(a) R1. For a lot located in a Hillside Area or Coastal Zone, the maximum floor area shall comply with Section 12.21.1 A.1. of this Code.
For lots outside of a Hillside Area or Coastal Zone, the maximum Residential Floor Area contained in all buildings and accessory buildings shall not exceed 45 percent of the lot area (a Residential Floor Area ratio of 0.45).
The encroachment plane shall originate from a point that is 20 feet in height from the existing or finished grade, whichever is lower, along the required front and side yard setbacks.
(b) R1V, Variable-Mass. These zones are intended to address issues of neighborhood character and to facilitate the compatibility of new construction, additions, and alterations in single-family neighborhoods having an existing variety of building forms. The intent of this variation is to allow flexibility in the location of massing within a maximum building envelope that respects the scale of other houses in the vicinity.
The maximum Residential Floor Area contained in all buildings on a lot shall not exceed the specified Residential Floor Area ratio for the corresponding zone per size of the lot as listed in Table 12.08 C.5.(b). The maximum lot coverage, maximum Height of Building, and maximum height at which the encroachment plane begins shall not exceed the amounts specified for each zone in Table 12.08 C.5.(b).

(e) R1H, Hillside Area. These zones are intended to address issues of neighborhood character and to facilitate the compatibility of new construction, additions and alterations to one-family houses in Hillside Areas having an existing variety of building forms. The intent of this variation is to allow flexibility in the location of massing within a maximum building envelope that respects the scale of other houses in the vicinity. A lot designated an R1H Zone shall comply with all of the R1 Hillside Area Development Standards pursuant to Section 12.21 C.10., except that R1H lots shall be subject to the Residential Floor Area ratios in Table 12.21 C.10-2b of their corresponding zone.
6. Verification of Existing Residential Floor Area. (Amended by Ord. No. 184,802, Eff. 3/17/17.) For additions with cumulative Residential Floor Area of less than 1,000 square feet constructed after January 1, 2008, or remodels of buildings built prior to January 1, 2008, the existing Residential Floor Area shall be determined based on the building records or the building square footage shown on the most recent Los Angeles County Tax Assessor’s records at the time the plans are submitted to the Department of Building and Safety and a plan check fee is paid. Except that Residential Floor Area may be calculated as defined in Section 12.03 of this Code when a complete set of fully dimensioned plans with area calculations of all the structures on the lot, prepared by a licensed architect or engineer, is submitted by the applicant.
Any work that does not qualify as a remodel, as defined in the paragraph below, or additions that are 1,000 square feet or larger shall require a complete set of fully dimensioned plans with area calculations of all the structures on the lot prepared by a licensed architect or engineer.
For the purposes of implementing this subdivision, a remodel shall mean the alteration of an existing building or structure provided that at least 50 percent of the perimeter length of the contiguous exterior walls and 50 percent of the roof are retained.
7. Definitions and Standards. (Added by Ord. No. 184,802, Eff. 3/17/17.) For the purposes of this Subsection the following definitions and standards shall apply:
a. Height of Mass, Front or Rear. The height of the front mass is the vertical distance above Grade measured to the highest point of the roof, structure, or parapet wall, whichever is highest of the front mass. The height of the rear mass is the vertical distance above Grade measured to the highest point of the roof, structure, or parapet wall, whichever is highest of the rear mass. Retaining walls shall not be used for the purpose of raising the effective elevation of the finished grade for purposes of measuring the height of either mass.
However, whenever the highest point of elevation of the adjoining sidewalk or ground surface within a 5-foot horizontal distance measured from the exterior wall of a building exceeds grade level by more than 20 feet, a building or structure may exceed the maximum front or rear mass height in number of feet prescribed in this section by not more than 12 feet. However, such additional height shall not be permitted to the extent that such additional height causes any portion of the building or structure to exceed a front or rear mass height in number of feet as prescribed by this section as measured from the highest point of the front or rear mass roof structure or parapet wall to the elevation of the ground surface which is vertically below this point of measurement.
b. Lot Coverage is the area of a parcel covered by any structures extending more than six feet above grade. However, 400 square feet of required covered parking that is detached and located within the rear half of the lot shall be exempt from lot coverage calculations.
(Added by Ord. No. 161,716, Eff. 12/6/86.)
The following regulations shall apply in the RU Residential Urban Zone:
A. Purpose. The regulations set forth in this section are designed to encourage the subdivision of small single-family residential lots for development with manufactured homes, including mobilehomes installed on permanent foundations, factory-built homes, or conventional site built homes.

Any of the uses permitted by Subsection B. of this section shall require prior approval in accordance with the provisions of Section 12.24.1 of this Code.
(Added by Ord. No. 159,532, Eff. 1/3/85.)
The following regulations shall apply in the RZ Residential Zero Side Yard Zone.
A. Purpose. The regulations set forth in this section are to provide for a 0-foot side yard, single- family residential zone.
B. Use. No building, structure or land shall be used and no building or structure shall be erected, structurally altered, enlarged, or maintained, except for the following uses, and, when a “Supplemental Use District” is created by the provisions of Article 3 of this chapter, for such uses as may be permitted therein:
1. Dwellings constructed across not more than five contiguous lots with no more than one dwelling unit on each lot, provided that:
a. The dwelling unit on each lot shall be structurally separated from the dwelling unit on the adjacent lot, provided, however, that footings slab foundations, roof sheathing, roofing and exterior wall coverings may cross the lot lines. Adjacent dwelling units shall be separated by walls which comply with the provisions of the exception of Section 91.0502 (h)2.A. of this Code and which extend from the slab foundation to the roof sheathing. Common footings on the lot lines shall underlie and support said walls between dwelling units.
b. Electrical, plumbing, heating, air conditioning and sewer systems for each dwelling unit shall be separate and independent of such system for each other dwelling unit.
c. Prior to the issuance of any building permit for such development, the owner or owners shall execute and record a declaration of covenants, conditions and servitudes in a form designed to run with the land and satisfactory to the City Attorney, binding themselves and all future owners and inuring to their mutual benefit and that of the City of Los Angeles.

(Added by Ord. No. 138,095, Eff. 4/19/69.)
The following regulations shall apply in the “RW1” Residential Waterways Zone:
A. Purpose. The regulations set forth in this section are to make possible the utilization of certain lots fronting on navigable public canals or waterways, or separated therefrom only by a public street, which make up, or are a portion of, a sizeable system of recreational waterways when such lots are predominantly those which were recorded prior to June 1, 1946.
Because of exceptional past history, present conditions, the proximity of such lots to recreational water areas, and their usual location in areas which enjoy optimum climatic conditions, the best development of the property may require variation from some of the standard housing requirements necessary or desirable in the rest of the City.
B. Use. No building, structure or land shall be used and no building or structure shall be erected, structurally altered, enlarged, or maintained, except for the following uses, and when a “Supplemental Use District” is created by the provisions of Article 3 of this chapter, for such uses as may be permitted therein:
1. One-family dwelling.
2. Accessory buildings, including private garages, accessory living quarters, servants quarters, or recreation rooms, provided that:
(a) No accessory living quarters nor servants quarters are located or maintained on a lot having an area of less than 4,600 square feet.
3. Conditional uses enumerated in Section 12.24 when the location is approved pursuant to the provisions of said section.

5. Name plates and signs, and required automobile parking spaces as provided for in Section 12.21 A. of this Code. (Added by Ord. No. 171,427, Eff. 1/4/97, Oper. 3/5/97.)
C. Area. No building or structure shall be erected or maintained nor shall any building or structure be enlarged unless the following yards and lot areas are provided and maintained in connection with such building, structure or enlargement:
1. Front Yard – There shall be a front yard of not less than ten feet in depth. Notwithstanding any provisions of this article to the contrary;
(a) The front yard shall be measured from the lot line nearest to, or separating the lot from, the navigable public canal or waterway, and in the case of a corner lot, from the line separating the narrowest canal frontage of the lot from the navigable public canal or waterway, or from the public street lying between the lot and the navigable public canal or waterway, except in those cases where the latest tract deed restrictions specify another line as the front lot line.
(b) No stairway, platform, landing, or porch shall extend or project into said required front yard space more than 48 inches, and in no case shall any such stairway, platform, landing, or porch exceed a height of 30 inches above the finished ground level adjacent thereto in said front yard space.
(c) No cornice, belt course, still or other similar architectural projection, but not including eaves, shall project into said required front yard space more than 12 inches.
