Permit timeline

Across Los Angeles, a ADU permit stays open about about 12 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 ADU jobs take.

  • Do you handle the plans, engineering and utility hookups, or do I?
  • How long from permit to the final inspection on your last three ADUs?
  • What is the payment schedule, and what is extra?
