Question 4

How long does it take to build an ADU or complete a remodel in the Bay Area?

Accepted Answer

Timelines vary by project type. Garage conversion ADU: 4–7 months. Detached ADU: 9–14 months. Kitchen remodel: 4–8 weeks. Bathroom remodel: 2–4 weeks. Room addition: 3–6 months. Every CoGeneral project includes a specific written timeline before work begins.

Question 5

How long does the permitting process take in the Bay Area?

Accepted Answer

Permitting timelines vary by city. Sunnyvale and Mountain View are among the fastest — typically 4–6 weeks. San Jose runs 6–8 weeks for standard applications. Palo Alto and Los Gatos can take longer due to additional review requirements, often 8–16 weeks. Cities are required by California law to act on complete ADU permit applications within 60 days. The most common cause of delays is incomplete or incorrect applications — which is why we handle the entire process and submit correctly the first time.
