Div. 6C.1. MAXIMUM DENSITY

The maximum number of dwelling units allowed on a lot.

A. Intent

The intent of regulating the number of dwelling units based on a fixed number per lot is to provide a method to establish a specific maximum number of dwelling units, regardless of lot area.

B. Applicability

Dwelling units per lot applies to any project that includes dwelling units and is constructed in a Lot-Limited Density District .

C. Standards

1. Regardless of lot area, the number of dwelling units is limited to the maximum dwelling units per lot outlined in Div. 6B.1 (Lot-Limited Density Districts) above.

2. Where a lot is large enough to be subdivided following the applied Form District (Part 2B.) lot area standards and the subdivision requirements in Article 11. (Division of Land), each new lot is entitled to the dwelling units per lot established by the applied Density District.

D. Measurement

1. Dwelling units per lot is measured as the cumulative number of dwelling units on a lot.

E. Exceptions

Accessory dwelling units and junior accessory dwelling units, compliant with Div. 9.5. (Accessory Dwelling Unit Incentive Programs), are exempt from the density limit for lots having one or more dwelling units.

F. Relief

1. An increase in the dwelling units per lot may be granted as a variance in accordance with Sec. 13B.5.3. (Variance).

[ FORM - FRONTAGE - STANDARDS ] [ USE - DENSITY ] City of Los Angeles Div. 6C.1. (Maximum Density) Zoning Code Chapter 1A

The maximum number of household dwelling units allowed on a lot based on lot area.

A. Intent

The intent of regulating the lot area per household dwelling unit is to provide a method that
ensures there is a specified maximum ratio of household dwelling units in relation to the size of a
lot.

B. Applicability

Lot area per household dwelling unit applies to any project that includes household dwelling units
in a Lot Area-Based Density District (Div. 6B.2.).

C. Standards

The number of household dwelling units on a lot shall not exceed the maximum established by the
applied Density District in Div. 6B.2. (Lot Area-Based Density Districts).

D. Measurement

1. The maximum number of household dwelling units is calculated by dividing the lot area by
the lot area per household dwelling unit value outlined in Div. 6B.2. (Lot Area-Based Density
Districts), and can be provided in combination with efficiency dwelling units where permitted,
as calculated in Sec. 6C.1.3. (Lot Area Per Efficiency Dwelling Unit).

a. Lot area that has been committed to the minimum lot area required per household
dwelling unit cannot be counted toward the minimum lot area required for an efficiency
dwelling unit.

b. Example:

i. A 5,000 square-foot lot with a 10 Density District could have five household dwelling
units, or three household dwelling units plus four efficiency dwelling units, or any
combination that does not exceed the maximum number of dwelling units permitted
by the ratios.

ii. If this same lot had five household dwelling units, it would not be able to add any
efficiency dwelling units, as the 5,000 square feet of the lot would have been
committed to the minimum lot area required for the allowance of the five household
dwelling units.

2. For lots that are adjacent to one or more alley, the maximum number of household dwelling
units may be calculated using the lot area plus the area between the exterior lot lines and the
centerline of the alley.

3. Fractions of units do not count towards an additional household dwelling unit, except as
permitted in Article 9. (Public Benefit Systems).

[ FORM - FRONTAGE - STANDARDS ] [ USE - DENSITY ] City of Los Angeles Div. 6C.1. (Maximum Density) Zoning Code Chapter 1A

4. When density is designated as "Limited by floor area", there is no maximum density. Household dwelling units are limited only by the physical constraints of the applied Form District (Part 2B.). 5. When density is designated as "Not Permitted", household dwelling units are not permitted. E. Exceptions Accessory dwelling units and junior accessory dwelling units, that comply with Div. 9.5. (Accessory Dwelling Unit Incentive Programs) are exempt from the density limit for lots having one or more dwelling units. F. Relief 1. A decrease in the minimum lot area per household dwelling unit may be granted as a variance pursuant to Sec. 13B.5.3. (Variance). 2. For projects that include multiple parcels with different applied Density Districts (Part 6B.), the transfer of density across the development site may be granted, in accordance with Sec. 13B.2.2. (Class 2 Conditional Use Permit). a. Supplemental Findings In addition to the findings in Sec. 13B.2.2. (Class 2 Conditional Use Permit), the Zoning Administrator shall also find that the project meets the following conditions: i. The project meets the definition of unified development. ii. All lots included in the project have Commercial-Mixed Use Districts (Div. 5B.5.), Industrial-Mixed Use Districts (Div. 5B.6.), or Industrial Use Districts (Div. 5B.7.) applied, or the project is located entirely in the Downtown Community Plan Area and all lots included in the project have Residential-Mixed Use Districts (Div. 5B.4.), Commercial- Mixed Use Districts (Div. 5B.5.), Industrial-Mixed Use Districts (Div. 5B.6.), or Industrial Use Districts (Div. 5B.7.) applied. iii. Where any individual lot exceeds the maximum density specified by the applied Density District (Part 6B.), the total number of dwelling units across all lots included in the unified development shall not exceed the sum of the maximum number of dwelling units allowed across all lots as calculated based on the maximum density specified by each applied Density District (Part 6B.). b. Supplemental Procedures If the Zoning Administrator approves the density transfer, then prior to the issuance of any building permit, the property owner shall file with the Department of Building and Safety a covenant running with the land that specifies the following obligations: i. The operation and maintenance of the development as a unified development is continued in perpetuity;

Div. 6C.2. MINIMUM DENSITY

A. Intent

The Minimum Dwelling Units per Lot Area standard is intended to implement State housing element law requirements for designated Lower Income Housing Element Rezoning Sites, and to advance the goals, policies, and objectives identified in the 2021-2029 Housing Element.

B. Applicability

1. The Minimum Dwelling Units per Lot Area standard applies when a project involves the following project activities: new construction, major remodel, exterior modification, use modification, temporary use, demolition, renovation.

2. The minimum density rules in this Section (Minimum Dwelling Units Per Lot Area) apply to any project that includes dwelling units located on a lot where Minimum Dwelling Units per Lot Area is listed in Div. 6B.2. (Lot Area-Based Districts) as “Applicable”, “Market-Contingent”, or “As Mapped” by the applied Density District (Part 6B.).

C. Standards

1. Applicable

Where the applied Density District specifies Minimum Dwelling Units per Lot Area as “Applicable” any project on the lot must propose a minimum of one dwelling unit per 2,000 square feet of lot area, which can be a combination of household dwelling units and efficiency dwelling units where permitted. Dwelling units provided as accessory dwelling units, pursuant to Div. 9.5. (Accessory Dwelling Unit Incentive Program), count toward the required minimum density on the lot.

2. Market Contingent

   a. Where the applied Density District specifies Minimum Density as “Market-Contingent,” any project on a lot that is located within a High or Medium High Residential Market Area as identified by City Council resolution pursuant to Sec. 15.4.3.C.1. (Affordable Housing Linkage Fee), must propose a minimum of one dwelling unit per 2,000 square feet of lot area, which can be a combination of household dwelling units and efficiency dwelling units where permitted. Dwelling units provided as accessory dwelling units, pursuant to Div. 9.5. (Accessory Dwelling Unit Incentive Program), count toward the required minimum density on the lot.

   b. Where the applied Density District specifies Minimum Density as “Market-Contingent,” any project on a lot that is located within a Low, Medium, or Not Applicable Market Area as identified by City Council resolution pursuant to Sec. 15.4.3.C.1. (Affordable Housing Linkage Fee), are not subject to any minimum density requirements, unless they are located on a lot mapped on the Lower Income Rezoning Housing Element Sites Map

[ FORM - FRONTAGE - STANDARDS ] [ USE - DENSITY ] City of Los Angeles Div. 6C.2. (Minimum Density) Zoning Code Chapter 1A

(Sec. 1.5.15.). If the project is located on a lot mapped on the Lower Income Rezoning
Housing Element Sites Map (Sec. 1.5.15.), the project shall include a minimum density of 20
dwelling units per acre, which may include a combination of household dwelling units and
efficiency dwelling units where permitted. Dwelling units provided as accessory dwelling
units, pursuant to Div. 9.5. (Accessory Dwelling Unit Incentive Program), count toward the
required minimum density on the lot.

3. As Mapped

a. Where the applied Density District (Part 6B.) specifies Minimum Density as “As Mapped,”
any project on a lot mapped on the Lower Income Rezoning Housing Element Sites Map
(Sec. 1.5.15.) shall include a minimum density of 20 dwelling units per acre, which may
include a combination of household dwelling units and efficiency dwelling units where
permitted. Dwelling units provided as accessory dwelling units, pursuant to Div. 9.5.
(Accessory Dwelling Unit Incentive Program), count toward the required minimum density
on the lot.

b. Where the applied Density District specifies Minimum Density as “As Mapped,” any project
on a lot that is not mapped on the Lower Income Rezoning Housing Element Sites Map
(Sec. 1.5.15.) is not subject to any minimum density requirements.

D. Measurement

1. The required minimum number of household dwelling units is calculated by dividing the lot
area by 2,000 square feet, and can be provided in combination with efficiency dwelling units
where permitted, as calculated in Sec. 6C.1.3. (Lot Area per Efficiency Dwelling Unit). Lot area
that has been committed to the minimum lot area required per household dwelling unit does
not count toward the minimum lot area required for an efficiency dwelling unit. An Accessory
Dwelling Unit counts toward the required minimum number of household dwelling units.

2. For lots that are adjacent to one or more alleys, the minimum number of household dwelling
units may be calculated using the lot area plus the area between the exterior lot lines and the
centerline of the alley.

3. If the minimum number of household dwelling units is a fraction, the minimum density
required shall be rounded up to the nearest unit.

4. When density is designated as "Not Permitted," household dwelling units are not permitted.

E. Exceptions

A project or lot that meets any of the following criteria is exempt from the minimum density
requirement established in Subsection C. (Standards), above. However, a project or a lot located
on the Lower Income Rezoning Housing Element Sites Map (Sec. 1.5.15.) is not subject to the
exceptions listed below and must comply in all cases with the requirements of Subsection C.
