ADU permits and local rules in Eagle Rock
Who runs permits
LA Department of Building and Safety (LADBS) handles building permits. LA City Planning handles zoning.
Pre-approved ADU plans
Yes. LA's ADU Standard Plan Program lists dozens of plans already checked by LADBS for building code. The city's own plan is free; the rest are bought from their designers. LADBS still checks your lot for zoning and foundation.
What can slow you down
- LA has had limits on ADUs on lots that are both hillside and very high fire zone. Check your lot first.
- Steep lots often need soil reports and extra grading work.
- If your lot has rent-stabilized units, LA tenant rules can add steps.
