Permit timeline
Across Los Angeles, a addition permit stays open about about 13 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. Waiting for the permit adds about about 4 months. How long addition jobs take.
