Mixed-use zone refers to any zone classification that allows for both residential and nonresidential uses on the same lot.

Car share means a vehicle rental program designed for people to rent vehicles for short periods of time, such as a few hours, pay only for their usage, and access the car at any hour, not just  during business hours. The vehicles may be commercially or personally owned. Commercial car share companies generally offer a fleet of vehicles which may be picked up and returned to a designated parking spot, or are picked up and returned to non-designated parking spots.

The minimum size of an efficiency unit is 220 square feet, plus a code compliant closet and bathroom; however, the Ordinance does not specify any minimum square footage requirements  for an ADU or JADU, except for Movable Tiny Houses (MTHs). This provision refers to any other current or future zoning ordinances that would prohibit an efficiency unit ADU

A JADU shall be identified as a JADU on Building Permits, Certificate of Occupancy and other pertinent City records. The addition of a JADU changes the designation of the One-Family  Dwelling to a One-Family Dwelling and JADU. For purposes of any fire or life protection ordinance or regulation, a JADU shall not be considered a separate or new dwelling unit per GC 65852.22(d).  However, JADUs may be counted as housing units in reports to the Department of Finance as well as for the Regional Housing Needs Assessment (RHNA) and other housing unit reporting.

Los Angeles County Tax Assessor’s records may be used to establish the square footage of the single-family dwelling for the purpose of calculating the required impact fee for the ADU.

The fee must be proportional to the average size of all dwelling units on the Lot. Floor plans showing the sizes of all units may be required to make this determination. An applicant may  choose to pay the full fee in lieu of providing these plans.

Height of an ADU is generally measured as any other structure would be measured under the LAMC, given the governing height limit standards in the applicable zone, Height District, Hillside Area, Specific Plan area, or other Overlay. For the purposes of applying the 16 feet maximum height standard as required by state law (referenced in LAMC Section 12.22 A.33(c)(1)(iii), (g)(1), and GC Section 65852.2(e)(1)(D)), height shall be measured according to the standard Zoning Code definition of Height of Building or Structure in LAMC Section 12.03.

Living area is defined in state ADU law as “the interior habitable area of a dwelling unit, including basements and attics, but does not include a garage or any accessory structure.”

Square footage, square-feet and size are used in the ADU Ordinance to refer to various direct ADU size regulations (such as the 1,200 square foot limitation). These terms refer to the definition of Floor Area in LAMC 12.03, but does not include the definition of Residential Floor Area (RFA), nor does it include any non-conditioned spaces such as porches, patios or breezeways with solid or lattice roofs. Physically connected spaces that are conditioned but do not have an interior connection to the ADU are also not counted as ADU square footage.

A single-family dwelling or use means a Dwelling, One-Family. A multifamily dwelling or use means any Structure with more than one Dwelling Unit or Guest Room, and used for long-term dwelling. Transient short-term rental uses established or used for less than 30 days are not considered dwellings for the purpose of implementing LAMC 12.22 A.33. Areas zoned for these uses means zones in which these uses are a permitted use in the respective zone classification.
