ADU Construction in Los Angeles: Regulations & Opportunities

California has the most ADU-friendly legislation in the country. AB 68 and SB 13 (2020) streamlined ADU permitting, eliminated many local barriers, and capped impact fees for ADUs under 750 sq ft. Los Angeles has embraced these changes — LADBS processed over 5,000 ADU permits in 2025 alone.

LA homeowners can build one ADU and one Junior ADU (JADU) on most single-family lots. Detached ADUs up to 1,200 sq ft are permitted with 4-foot rear and side setbacks. JADUs (up to 500 sq ft) must be converted from existing space within the primary dwelling.

The rental income potential is substantial. A well-designed 600 sq ft ADU in a desirable LA neighborhood can generate $2,000–$3,500/month in rental income, making it one of the best investments available to LA homeowners.

Key Local Factors

AB 68/SB 13 eliminates most local barriers to ADU construction
Maximum size: 1,200 sq ft detached, 500 sq ft JADU
Setbacks: 4 ft rear and side for detached ADUs
Impact fees waived for ADUs under 750 sq ft
No parking required within ½ mile of public transit
Separate utility meters may be required for rental ADUs
HOA restrictions on ADUs severely limited by state law
