How to Fix It

If you've already built without a permit:

1. Stop work immediately 2. Contact the building department 3. Apply for a retroactive permit 4. Be prepared for inspections - May need to open walls 5. Pay any penalties assessed 6. Complete required corrections

The city generally wants to help you get compliant rather than punish you, but the process is more expensive than getting the permit upfront.
