Permit timeline

Across San Francisco, a remodel permit stays open about about 6 months, from permit to final inspection

This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. The permit itself is usually issued the same day. How long remodel jobs take.
