Selling a house with unpermitted additions or work
A basement finished or a deck added without permits won't stop a sale. It gives buyers questions, and it helps to have answers.
No obligation. No pressure. Takes about 2 minutes.
The short answer
Unpermitted work doesn't stop a sale, but it raises questions for buyers and their lenders. You can apply for a permit after the fact and get the work inspected, list with a price or credit that reflects the risk, or sell as-is to a buyer who'll deal with it. Before choosing, ask your local permit office what legalizing the work would take: in Baltimore, for example, work done without a permit needs one, with fees and penalties, and can be ordered restored unless it meets the rules and the building official lets it stay.
Step by step
-
1
Find out what was permitted
Ask your city or county permit office for the permit history of the house. Compare it with what's actually there: additions, finished basements, decks, electrical or plumbing changes.
-
2
Ask what legalizing would take
The permit office can tell you whether an after-the-fact permit is possible and what inspectors would need to see. Sometimes that means opening walls or ceilings; sometimes it's paperwork and a visit.

Be straight with buyers
Maryland's disclosure form asks whether improvements you or a contractor made had the required permits and passed inspection. Our Virginia, Maryland and DC seller disclosure guides explain what each state requires.

Weigh the options
An after-the-fact permit costs time and money but can clear the question for good. A price adjustment or credit keeps the sale moving without the work. Selling as-is for cash puts the permit question on the buyer.

We'll show the cash offer next to what listing could net after legalizing the work, so you can see whether the permit process pays for itself.
Frequently asked questions
Can I sell a house with an unpermitted addition?
Yes. You can permit it after the fact, price it in, or sell as-is. What changes is who deals with the permit question and what that costs.
The previous owner did the work. Is it still my problem?
Often, yes. In Baltimore, for example, the owner is responsible for building code compliance on the property, whoever did the work. Check your own city or county's rules.
Should I get a permit after the fact before listing?
It makes sense when the permit office's requirements are modest and you plan to list. If it would mean opening walls or major changes, compare that cost against a cash offer.
