- 3. Submit through the Detroit permit portal and pay the review fee.
- 4. Schedule each required inspection as the work reaches that stage.
- 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.
