Selling a House With Unpermitted Work in Texas: What to Disclose

Finished garages. A second bathroom. A panel upgrade nobody inspected. A deck that's stood for 15 years without a permit. Unpermitted work shows up in a lot of Texas homes, and it doesn't stop you from selling. It does change what you have to disclose, who can buy, and what the house is worth.

What Is Unpermitted Work?

Unpermitted work is any construction, repair, or installation that required a city building permit but was done without one, or where a permit was pulled and never closed out with a final inspection. It doesn't matter who did it. If you bought the house with a garage conversion the last owner never permitted, it's your unpermitted work now.

Painting, flooring, and cabinet swaps don't need permits. Anything touching structure, electrical, plumbing, gas, or livable square footage usually does:

• Additions and conversions: garage-to-living-space, new bedrooms or bathrooms, enclosed patios
• Electrical: new circuits, panel upgrades, major rewiring
• Plumbing and gas: moved fixtures, new bathrooms, gas water heaters
• Structural: removed load-bearing walls, roof changes, foundation work
• HVAC: new systems, ductwork, gas furnace replacements
• Decks and outbuildings: elevated decks, detached structures

Rules vary by city. A call to your city's building department will tell you what needed a permit when the work was done.

Selling a House Without Permits: What Texas Requires You to Disclose

Under Texas Property Code Section 5.008, most sellers of single-family homes must give the buyer a Seller's Disclosure Notice. The form asks directly whether there have been "room additions, structural modifications, or other alterations or repairs made without necessary permits." If you know about unpermitted work, you check yes and describe it.

Be specific. "Bathroom updates" isn't a disclosure. This is: "Added second bathroom to primary bedroom in 2018. Licensed plumber did the work. No building permit was pulled." Vague answers leave room for a buyer to argue they weren't told.

Timing matters too. Deliver the notice before the contract's effective date. If the buyer gets it afterward, §5.008(f) gives them 7 days to terminate for any reason.

How to Find Out What's Unpermitted on Your Property

Pull your permit history. Houston, Dallas, Austin, and San Antonio all have searchable permit records online, and smaller cities will pull them if you call. Compare every permit on file to the work you know was done.

Look for the tells. A room that looks newer than the rest of the house, outlets in odd places, plumbing that doesn't line up with the original layout.

Get a pre-listing inspection. $300 to $600. Better to hear about it now than from the buyer's inspector during the option period.

Your Three Options

Option 1: Get Retroactive Permits

Most Texas cities, including the Houston suburbs, will permit work after the fact. You apply, the city inspects, and you fix anything that doesn't pass. Some cities may require opening walls so the inspector can see wiring or plumbing.

The catch is that the work has to meet today's code, not the code from when it was built. Older electrical work often needs upgrades. Budget a few hundred dollars in permit fees plus whatever corrections the inspector calls for, and plan on several weeks depending on your city's backlog.

Makes sense when: the work is solid, you have time before you need to close, and the cost is less than the discount you'd take selling it unpermitted.

Option 2: Disclose and List As-Is

You disclose, price the house to reflect the work, and list it. Expect a smaller buyer pool. FHA and VA appraisers may flag unpermitted additions for safety issues or leave the square footage out of the value, and some conventional lenders will require permits before they fund. That leaves cash buyers and motivated owner-occupants, and usually more time on the market.

Insurance can also come up. Some Texas insurers won't cover unpermitted structures, and a buyer who can't get a policy can't close. Disclosing early gives them time to shop insurers during the option period.

Makes sense when: permitting would be expensive, the work is minor, and you can accept a lower price and a longer sale.

Option 3: Sell to a Cash Buyer

Cash buyers like Bodebuilders buy homes with unpermitted work as-is. No permits, no appraisal, no lender conditions. Closings typically take 10 to 14 days. You still disclose, but you skip the permit costs, the financing fallout, and the repair negotiations.

The offer will be below retail. Whether that's worth it depends on how extensive the work is and what else is wrong with the house. When unpermitted work comes with other problems, like mold, water damage, or other damage, a traditional sale gets much harder and a cash sale usually makes more sense.

Makes sense when: you need to close fast, the work is extensive, or the house has other issues on top of it.

Which Unpermitted Work Causes the Most Problems

High risk: structural changes, additions that add livable square footage, and panel upgrades. Lenders balk and buyers walk.

Medium risk: new bathrooms, HVAC with gas connections, and decks with structural footings. These become negotiating points.

Lower risk: added outlets, replaced fixtures, and small changes that look professionally done.

Unpermitted work can also lead to open code cases. If the city has already cited the property, see how to sell a house with code violations in Texas. In extreme cases a city can condemn a house.

What Happens During the Sale and at Closing

Option period. Texas contracts usually include an option period where the buyer can walk for any reason. If their inspector finds unpermitted work you didn't list, expect them to renegotiate or terminate.

Appraisal. An appraiser generally won't count an unpermitted garage conversion as living space. If that pushes the value below the contract price, the buyer's loan has a problem. Cash sales skip the appraisal.

Title. The sale won't be blocked, but some title policies may exclude coverage for the unpermitted structure.

Will the city find out? Not automatically. Texas cities don't inspect at sale. But a buyer's future permit application, a renovation, or a neighbor complaint can trigger a review. Disclosure is what keeps that from coming back to you.

HOAs. If the work also breaks HOA rules, like a garage conversion that changed the exterior, the HOA can require restoration. Disclose both the permit issue and any HOA issue.

Property taxes. Once an addition is on record, the appraisal district may raise the home's value, and the buyer's tax bill goes up.

After closing. If you disclosed fully and the buyer signed with that knowledge, your exposure is limited. An as-is addendum helps, but it won't protect a seller who left something out.
