How long does an ADU permit take in Los Angeles?

Two numbers float around, and both are real. California ADU law requires the city to approve or deny a COMPLETE application within 60 days. The city's own permit records show the median time from application to issued permit in Valley ZIP codes running around 4 to 5 months. The gap between those numbers is the story.

The 60-day clock only starts when your application is complete, and most first submissions aren't. Plan check sends corrections, your designer responds, and each round trip adds weeks. Utility clearances, school fees, and any overlay review (historic zones, hillside, fire severity) run on their own clocks. None of that violates the 60-day rule; it just doesn't count against it.

What actually shortens the calendar: a designer who has permitted ADUs in your exact jurisdiction (their first submission comes back with fewer corrections), a pre-approved standard plan where one fits your lot (the city of LA's program includes a free one, and plan check shrinks to site-specific review), and answering corrections in days instead of weeks. The slowest projects are usually slow between the city's turns, not during them.

One thing that surprises people: the permit clock is separate from the decision clock. You can spend months deciding, designing, and pricing before anything is submitted. Homeowners who confirm feasibility first, then design against a real budget, tend to submit once and correct once.

The permit counts and median approval times on this site come from the city's own building records, refreshed weekly, broken out by ZIP code. Look up your ZIP on the ADU market page and you'll see how long your actual neighbors waited, not an estimate.
