What happens if I start work without a permit?
Immediate Consequences
If a local building department discovers unpermitted work, they can issue a stop-work order, fine you, and require you to remove or correct the work at your own expense. Fines vary widely by city and state, often starting around $100 and going up to $1,000 or more per day or per violation.
In some cases, the work may be unsafe and need to be torn out so inspectors can verify what's behind the walls. This can double or triple your original project cost.
Long-Term Problems
Unpermitted work can complicate selling your home. Buyers' lenders may refuse to finance a home with unpermitted additions, and title issues can arise. You might have to get a retroactive permit or tear out the work before closing.
Your homeowner's insurance may also deny claims for damage related to unpermitted work. For example, if an unpermitted electrical job causes a fire, the insurer could refuse to pay.
- Fines and penalties
- Stop-work orders
- Forced removal or correction
- Difficulty selling or refinancing
- Insurance claim denials
- Potential liability if someone is injured
Common mistakes
- Thinking you won't get caught—neighbors, buyers, and inspectors often report unpermitted work.
- Assuming a retroactive permit is guaranteed; many jurisdictions can refuse if the work doesn't meet current codes.
- Believing that minor work never needs a permit; even small electrical or plumbing changes often require one.
