  3. 3. Submit through the West Palm Beach permit portal and pay the review fee.
  4. 4. Schedule each required inspection as the work reaches that stage.
  5. 5. Get the final inspection signed off. An open permit can surface in a title search and often has to be closed before a sale completes, so do not leave it open.
