Permit timeline

Across New York, a addition permit stays open about about 15 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 6 months. How long addition jobs take.

Worth asking any home addition contractor

  • Can you show me proof of liability insurance and your bond?
  • Do you handle the plans and engineering, or do I hire them?
  • Who will run the job day to day, and who are the subcontractors?
  • Who pulls the permits, and what is the payment schedule?
