Understanding ADU Requirements in Los Angeles

Los Angeles has been at the forefront of promoting ADU development as a solution to the city’s housing crisis. The city’s ADU ordinance, which aligns with California state law, sets forth specific requirements for building an ADU on your property.

Size and Location Requirements

1. Detached ADUs: Can be up to 1,200 square feet or 50% of the primary dwelling’s floor area, whichever is less.
2. Attached ADUs: Limited to 50% of the primary dwelling’s floor area or 1,200 square feet, whichever is less.
3. Converted ADUs: No size limit if converted from existing space within the primary residence or accessory structure.
4. Junior ADUs (JADUs): Limited to 500 square feet and must be within the walls of the primary residence.

Setback Requirements

1. Side and Rear Setbacks: Minimum of 4 feet for new ADUs.
2. Front Setback: Must comply with underlying zone requirements.
3. Converted ADUs: No new setbacks required if the existing structure complies with building and safety codes.

ADU Rules Los Angeles Homeowners Should Know

Parking Requirements

1. Generally, no additional parking is required for ADUs in Los Angeles.
2. If you demolish existing parking to build an ADU, you must replace those spaces.

Owner-Occupancy

1. As of January 1, 2020, owner-occupancy is not required for ADUs in Los Angeles until January 1, 2025.
2. JADUs still require owner-occupancy in either the primary residence or the JADU.

Short-Term Rentals

ADUs in Los Angeles cannot be used for short-term rentals (less than 30 days).

Los Angeles ADU Laws: Recent Changes and Updates

The ADU landscape in Los Angeles has evolved rapidly in recent years. Here are some key changes:

1. Increased Size Allowances: The maximum size for detached ADUs increased from 1,200 square feet to 1,200 square feet or 50% of the primary dwelling’s floor area, whichever is less.
2. Relaxed Parking Requirements: The city no longer requires additional parking for most ADUs.
3. Multiple ADUs: Properties can now have both an ADU and a JADU.
4. Conversions of Unpermitted Units: Los Angeles now has a program to help homeowners legalize existing unpermitted ADUs.

The Los Angeles ADU Ordinance: Key Provisions

The Los Angeles ADU Ordinance, which was last updated in 2020, includes several important provisions:

1. Streamlined Approval: ADUs that meet all requirements are eligible for ministerial approval, meaning faster processing times.
2. Conversions of Existing Structures: Garages, basements, and other existing structures can be converted to ADUs without meeting current setback requirements.
3. ADUs in Multi-Family Zones: The ordinance allows for ADUs to be built in multi-family zones, not just single-family residential areas.
4. Design Standards: While the city encourages ADUs to match the design of the primary residence, there are no strict requirements for architectural style.

ADU Grants in Los Angeles: Financial Assistance Options

While Los Angeles doesn’t currently offer a city-specific ADU grant program, there are other financial assistance options available:

1. CalHFA ADU Grant Program: The California Housing Finance Agency offers grants of up to $40,000 for pre-development costs associated with ADU construction.
2. Los Angeles ADU Accelerator Program: While not a grant, this program offers incentives for homeowners who agree to rent their ADUs to Section 8 voucher holders.
3. FHA 203(k) Rehabilitation Loan: This federal program can be used to finance both the purchase of a home and the costs of its rehabilitation, including ADU construction.
4. Residential Seismic Retrofit Program: If your ADU project includes seismic upgrades, you may be eligible for financial incentives through this program.
