The short answer
Inside Austin city limits, most foundation repairs need a building permit. The city’s Types of Permits page lists foundation repair under the residential Minor Repairs permit, also called the Express permit. Only a repair of no more than 128 square feet is exempt. The neighboring cities run their own permit offices, and we couldn’t confirm their rules, so check with them directly.
| City | Permit for foundation repair? | Exemption | Engineer’s letter | What to do |
|---|---|---|---|---|
| Austin | yes (Minor Repairs / Express permit) | Repairs up to 128 square feet | Not mentioned on the pages we read | Have the contractor pull it; ask for the number |
| Cedar Park | Not confirmed: the city’s site blocked our requests | Unknown | Unknown | Call the city’s building office before work starts |
| Pflugerville | Not confirmed: the city’s site wasn’t readable to our tools | Unknown | Unknown | Call the city’s building office before work starts |
| Leander | Not confirmed: the city’s site blocked our requests | Unknown | Unknown | Call the city’s building office before work starts |
“Not confirmed” means we couldn’t read the rule, not that there isn’t one. Many Texas cities require a permit for foundation repair, and some require an engineer’s letter.
Austin’s Express permit, step by step
The City of Austin’s Express Permits page sets out how a Minor Repairs permit works:
- A registered general contractor. A registered general contractor must be assigned and linked to the permit. A homeowner can act as the general contractor after registering, which is separate from trade registrations for plumbing or electrical work.
- A portal account. Whoever is listed on the permit needs an account on the city’s Austin Build + Connect portal to pay fees, manage the permit and schedule inspections.
- The application. The contractor completes the Residential Express Permit application and submits it online with the required documents.
- Review and issue. The city says most Express permits are issued in about one business day, though timing may differ in a floodplain or historic district.
- Post and inspect. The permit is printed and posted at the house, and the required inspections are scheduled as the work goes.
If the work turns out bigger than an Express permit allows, the city requires a new residential permit application and fees, and says the Express fees aren’t refunded. Ask the contractor whether your job fits the Express category before work starts.
Plumbing permits
The Express page adds that for foundation repair a plumbing permit may be required depending on the work, and asks applicants to say so on the application. Any plumbing repair under the slab is a job for a licensed plumber under Texas law (state plumbing license required), who pulls the plumbing permit. If the plan includes a plumbing test or leak repair, ask who arranges it.
What about an engineer?
Austin’s Express pages ask for a sealed engineer’s report for fire and vehicle damage repairs, but the pages we read don’t mention one for foundation repair. That’s different from several North Texas cities, which require an engineer’s letter or sealed pier drawings with the permit application. An engineer may still review your plan, either because the contractor uses one or because you hire one. The engineer guide explains when that’s worth paying for.
Why the permit matters to you
Texas doesn’t license foundation repair contractors. A Senate bill analysis found no state regulation of foundation repair contractors (2011), and that bill was not enacted. The state also stopped registering home builders when the Texas Residential Construction Commission was abolished on September 1, 2009. A city permit is one of the few outside checks on the work: a registered contractor on record, and an inspection by the city.
It also matters when you sell. The Texas seller’s disclosure notice asks about any Previous Structural or Roof Repair, and buyers’ inspectors and lenders often ask for the permit and final inspection. The selling guide covers that side.
Outside city limits
Some Austin-area addresses are outside any city’s limits, in unincorporated parts of Travis or Williamson County. We haven’t researched county rules for foundation repair. If your address is outside a city, ask the contractor what applies and confirm with the county.
Before you sign
- Ask who pulls the permit, and get the permit number.
- Ask whether a plumbing permit is needed too, and who handles it.
- Ask whether an engineer reviews the plan, and whether you get a copy of anything they write.
- In Cedar Park, Pflugerville or Leander, call the city to confirm its rule.
- Keep the permit, inspection results and plan with your house records.
