What to ask before you hire

About Woolsey Construction

  • Ask what the warranty covers and for how long, in writing.

Worth asking any ADU builder

  • Can you show me proof of liability insurance and your bond?
  • 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?
