Building an ADU in the City of Los Angeles
We've built 200+ ADUs across Los Angeles — navigating LADBS, LA-specific zoning codes, and the city's permitting system so you don't have to.
Why Los Angeles Is One of the Best Cities in California to Build an ADU
Los Angeles has undergone a dramatic ADU reform since 2019. The city eliminated many of the restrictions that previously made ADUs impractical — including owner-occupancy requirements, minimum lot sizes, and excessive setback rules. Today, most single-family lots in the City of LA are eligible to add at least one ADU, and many can accommodate both an ADU and a Junior ADU on the same property.
With some of the highest rental demand in the country and median rents of $2,200–$3,500/month for a studio or one-bedroom, an ADU in Los Angeles can generate $26,000–$42,000+ in annual rental income. That's a compelling return on a $150,000–$280,000 investment — and one that compounds as property values rise.
- Highest rental demand in California — ADUs rent quickly in most LA neighborhoods
- No owner-occupancy requirement — rent both your home and your ADU
- LADBS Expedited ADU Plan Check Program significantly reduces permit wait times
- No minimum lot size requirement for ADUs under California state law
- Most lots can build both one ADU and one Junior ADU simultaneously
- ADUs are largely exempt from school and utility impact fees in the City of LA
