Median months from application to permit, one mark per ranked city, 2023–2025.
Building permits issued for ADUs, from state housing reports.
Estimates come from the Bay Area ADU Permit Clock. Waits run from the application date to the building permit date and include correction rounds and your own revision time, so a complete first submission is the best way to land nearer the fast date. The state review limit is in Government Code section 66317. Everything runs in your browser; nothing you pick is saved or sent.
Common questions
How is the ADU timeline estimated?
From the real waits of ADUs permitted in your city in 2023–2025, matched from the application date to the building permit date in state housing reports. "Likely" is the median, "fast" the 25th percentile and "slow" the 75th. Move-in adds the median time from permit to certificate of occupancy.
Why is my estimate longer than the 60 days in state law?
The 60-day clock in Government Code section 66317 starts only once the city deems your application complete. Real waits include rounds of corrections, your own redesign time, and paying fees before the permit is issued.
What if my city has no data?
We fall back to the Bay Area figures (median 6.0 months to permit) and say so in the result.
