Permit History: What a House's Paper Trail Tells You Before You Buy

The listing calls it "newly renovated." The building department has an opinion about that, written in permits — and it is one of the few opinions in real estate that is entirely public. Checking a home's permit history takes one request to the county or city, and it can change what you offer, what your insurer charges, and what you inherit.

The three states of a permit

• Finaled (closed). The work was inspected and signed off. This is what you want behind every renovated kitchen and added bathroom.
• Open or expired. Work was started — or at least permitted — and never passed final inspection. An open permit can become your problem at resale, refinance, or when the next job's inspector notices it. Sellers should close these before closing; make it a contract item, not a hope.
• Missing entirely. A visibly renovated home with no permit record for the work is the classic trap: the flip was cosmetic by design, or the work is unpermitted and uninspected. Either way, the burden of proof shifts to the seller.

What to ask for, exactly

Ask the building department for the permit history at the address — most counties offer it online. Match what you find against what you see: roof age versus roof permits, the "new panel" versus an electrical permit, the finished basement or garage conversion versus any permit at all. A finished space that was never permitted may not count as legal living area in an appraisal, which can collapse your loan math late in the process.

The insurance angle nobody mentions

Unpermitted work is an insurance problem waiting for a claim. If a fire traces to unpermitted wiring, the carrier has an argument you do not want to fund. Insurers increasingly ask about renovation permits on new policies in high-risk states — one more reason the file belongs in your pre-offer homework, not your post-closing surprises.

Frequently asked questions

How far back does the permit record go?

It varies by jurisdiction; digitized records often cover a few decades, older work may need an in-person file pull. Even a partial record is useful — recent work is where the risk concentrates.

The seller says the work predates permits being required. Possible?

For genuinely old work, possible. For a 2024 kitchen, no. Dates are on the record; compare them to the listing's claims.

Can I make the seller close open permits before closing?

Yes — it is a common contract contingency and a reasonable one. Get it in the contract, with final inspection sign-offs as the evidence.
