How do you check if work on a house was done with a permit before you buy it?
One of the smartest things you can do before buying a house is verify that major work was completed with the proper permits. Unpermitted renovations aren’t always deal-breakers, but they can lead to safety concerns, insurance issues, financing complications, and unexpected expenses down the road.
Here’s the approach I’d recommend:
Start with the local building department. Most cities and counties keep permit records that are publicly available online or through a simple records request. Look up the property’s address and compare the permit history to what you’re seeing in the home.
Pay close attention to major projects such as:
- Room additions
- Finished basements
- Decks and patios
- Electrical upgrades
- Plumbing work
- Roofing replacements
- HVAC installations
- Garage conversions
If the home has a newly finished basement but no permit record for the work, that’s worth investigating further.
Next, ask the seller directly for documentation. A reputable homeowner should be able to provide permit approvals, inspection reports, contractor invoices, or final sign-offs for significant renovations.
A good home inspector can also help spot red flags. While inspectors can’t always determine whether a permit was obtained, they often notice signs of amateur workmanship, code violations, or modifications that don’t appear original to the house.
Another useful clue is comparing property records to the actual home. If county records show a 1,800-square-foot house but you’re standing in what appears to be a 2,200-square-foot home, there may have been additions or conversions that weren’t properly documented.
If you discover unpermitted work, don’t panic. Many homes have minor improvements completed without permits. The key is understanding the scope of the work, the potential risks, and whether the seller can resolve any issues before closing.
As a buyer, I’d rather uncover permit problems before making an offer than inherit them after moving in. A few hours of research can save you thousands of dollars and a lot of headaches later.
