Los Angeles ADU Frequently Asked Questions

Can I sell my ADU as a separate condo in Los Angeles?

California passed AB 1033 allowing cities to permit ADUs to be sold separately as condominiums. Check with LADBS as local ordinances implement this opt-in policy.

Do I have to pay impact fees for an ADU in Los Angeles?

No, California state law completely exempts ADUs under 750 sq ft from all local development impact fees. For ADUs 750 sq ft or larger, impact fees are assessed proportionally to the main home size.

What is the standard setback for an ADU in LA?

Rear and side setbacks are standard 4 feet. Converted existing structures (such as garages) maintain existing setbacks down to 0 feet.
