What the TREC rule makes an inspector give you
The rule text on TREC's standards page reads: the inspector shall "render a written opinion as to the performance of the foundation." TREC's guide, dated April 29, 2025, says inspectors must rely on visual inspection only. They're required to generally report present and visible indications of adverse performance. Doors that bind, framing separations, sloping floors, cracks and buckling masonry are its examples.
Elevation readings aren't part of it. The rule doesn't require thermal imaging, elevation measurement or load tests, so a buyer who wants a floor survey has to order one.
Foundation inspection prices in Texas: our estimate
We estimate an inspection at $300 to $1,100 per inspection. It's a model, not a quote, built from 2 national published ranges, scaled by the Texas civil engineer wage ratio, and stretched to cover the lowest and highest of two Texas company prices. A home-sale inspection and an engineer's sealed report are different jobs. Ask which one the price is for.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $300 to $1,100 per inspection | Built from 2 national published ranges, adjusted by the Texas civil engineer wage ratio (0.96), then widened to take in the lowest and highest of the two Texas company prices for this job ($300 to $1,100). Ten Texas foundation companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Basis: small sample (2), national estimate joined with the company range. |
| Civil engineers, mean hourly pay in Texas | $50.12 an hour | BLS figure for May 2025, the occupation nearest to an engineer's foundation visit; pay, not a fee. |
| Civil engineers, mean hourly pay nationwide | $52.24 an hour | Same BLS release for the whole country; Texas pay over this gives the ratio. |
Estimated range. Built from national published ranges (2 sources), adjusted by Texas's civil engineer wage ratio to the US (0.96, BLS May 2025). Not a quote. Ten Texas foundation companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Only two Texas companies publish a price we could count for this job, too few for a range of their own, so the range is our national estimate widened to take in their lowest and highest prices. Full method. Prices as of Oct 23, 2026.
The ASCE Texas Section guidelines
The Texas Section of the American Society of Civil Engineers publishes Guidelines for the Evaluation and Repair of Residential Foundations, Version 3, effective April 1, 2022. Its page says they "are not intended to be Standards but are guidelines only," written to guide the engineering board in evaluating complaints against engineers.
None of the 25 cities' permit pages, fee schedules or forms names them. Amarillo's 2017 Panhandle Residential Foundation Manual reprints a different Texas Section document, the 2007 design practice for new foundations.
When the report should come from an engineer
TBPELS's Policy Advisory Opinions index lists number 43, on whether TREC inspectors do engineers' work when they give a foundation opinion (closed November 16, 2017), and number 44, on foundation repair methods (closed January 23, 2018). The index prints titles, not the Board's answers, so read the opinions themselves on that TBPELS page before you lean on either.
At the city counter it's settled in writing. San Antonio wants an Assumption as Engineer of Record letter, Garland an engineer's final report, and Denton an engineer-sealed letter and plan before a residential foundation repair goes ahead.
Inspecting a house you're buying
The seller's side comes on TREC Form 55-1, effective 05/28/2026. It asks about Foundation/Slab(s) defects, previous structural repair, and landfill, settling, soil movement or fault lines, each answered yes if the seller knows of it.
When an inspection can't wait for a convenient day
- A section of floor or wall has dropped or leaned within the last few days.
- A beam, post or lintel is visibly bending or has cracked through.
- Water is reaching an outlet, the panel or a wall with wiring in it.
- A pre-purchase opinion before closing, on a house where nothing is moving.
Before you book an inspection
- Ask the inspector to confirm the foundation opinion will be in writing, as 535.228(a) requires.
- Ask whether whoever writes the report would also be paid for a repair.
- Keep the seller's Form 55-1 with the report, and show both to every company that quotes.
Permits and who regulates the person inspecting
Texas cities print permits for the repair that may follow an inspection. Denton, for one, wants the final engineered seal report uploaded to eTRAKiT before its final inspection. The inspector answers to TREC under 16 TAC 535.228, and an engineer to TBPELS.
Texas has no state license for foundation repair, so ask for the contractor's certificate of insurance and call the insurer listed on it before you sign anything.
Questions people ask
What does a Texas home inspector have to say about the foundation?
A written opinion on how it's performing, from visual inspection only. 16 TAC 535.228(a) requires that opinion. TREC adds that the inspector reports present and visible indications of adverse performance, with no duty to measure elevations or run load tests.
What does a foundation inspection cost in Texas?
Our model gives $300 to $1,100 per inspection for an inspection, and it isn't a quote. Two Texas companies publish a price for this job, short of the five it takes to set a range of their own. Ask if the price buys an inspector's visit or an engineer's sealed report.
Do cities have to follow the ASCE foundation guidelines?
The Texas Section calls them guidelines only. Its page says Version 3 isn't intended to be a standard, and no permit page, fee schedule or form from the 25 cities names it.
Is an engineer needed for a foundation inspection?
For a sale, the TREC inspector's opinion is the one the rule requires; for a repair permit, cities ask for an engineer. San Antonio, Garland, Grand Prairie and Denton print engineer letter or plan requirements for their foundation repair permits.
What does the seller's disclosure ask about the foundation?
Form 55-1 covers Foundation/Slab(s) defects, past structural repair and soil movement. Item 9 on the same form asks about alterations or repairs made without necessary permits.
