Independent Structural Engineer Foundation Evaluation in Collin County

What an engineer's evaluation is

A foundation evaluation by a structural engineer is a site visit and a written report. Engineers commonly walk the outside and inside of the house, note cracks, doors, drainage and trees, and take a set of relative floor elevations with a level or survey instrument to map how the foundation has moved. The report gives the engineer's professional opinion on the foundation's condition and, where repair is warranted, what it should involve. If repair goes ahead, the same engineer can prepare the sealed repair plan the city asks for, inspect the work, and write the final letter.

The scope varies from firm to firm. Some offer a short walk-through letter, others a fuller report with an elevation map and photos. Ask what you will get in writing before you book.

Why it matters in Texas

Diagnosing a foundation is engineering

In February 2018 the Texas Board of Professional Engineers (now the Texas Board of Professional Engineers and Land Surveyors, TBPELS) issued advisory opinion 43. It says:

"Analyzing the cause of a condition, recommendations for repair, or providing any other expert engineering opinion associated with a foundation ... would be considered the practice of engineering ... and could warrant disciplinary action ... if conducted by an individual unlicensed as a Professional Engineer (PE)."

The same opinion explains that a real estate inspector licensed by the Texas Real Estate Commission reports visible conditions, but is not required to determine "the cause or source of a condition," and may not give an engineering opinion on a foundation without a PE license. In other words, the home inspector flags symptoms, and the engineer interprets them.

There's no state license for the repair company

Texas does not license foundation repair companies. Bills to create a license failed in 2011 and 2013. The engineer is the licensed professional in the process, which makes their independence more important.

Cities require a sealed design

Every Collin County city checked for this guide ties the repair permit to an engineer:

• McKinney: an engineer's letter and drawings to get the permit, and a Final Engineer's Report uploaded to close it. The city says repaired foundations "are required to be engineered by a licensed professional registered in the state of Texas" (McKinney guidelines).
• Plano: foundation plan, pier details and engineer's letter, all "dated, designed, sealed and signed by a State of Texas Registered Engineer" (Plano handout).
• Frisco: stamped engineer letter and stamped pier drawings, plus an engineer's inspection report at completion (Frisco submittal requirements).
• Prosper: an original engineer-sealed design, and a second sealed letter at inspection confirming the work matched the design (Prosper FAQ).

Allen's rules couldn't be confirmed for this page, so check with the city.

State law also speaks to this. The Texas Engineering Practice Act generally exempts work on a private home, but it carves out "engineering design relating to constructing, enlarging, altering, or repairing ... a residential dwelling slab located on expansive soil" unless the work meets International Residential Code requirements (Occupations Code section 1001.056). How that applies to a given house is a question for the engineer or the city, and in practice the city permit rules above already require an engineer.

Independent vs company-arranged engineers

Many repair companies arrange the engineer themselves. That is legal and common, and many of those engineers do careful work. The concern is incentive. In 2017 a Dallas engineer asked the state board to address engineers "working on behalf of, or ... recommended by, the Foundation company who directly benefits" from the engineer's sign-off. The Board declined to issue an opinion but said it will investigate substantiated complaints against engineers who design repairs "without proper analysis."

Hiring your own engineer first has practical benefits:

• Every company bids the same design, so you can compare prices fairly.
• The engineer can tell you if repair isn't needed yet, or if drainage or plumbing should come first.
• The engineer inspects the finished work on your behalf.
• The reports stay with you for resale and warranty questions; see warranties and resale.

How to find and check an engineer

1. Search for structural or forensic engineers who do residential foundation evaluations in Collin County. Real estate agents, home inspectors and neighbors are common sources of names.
2. Check the license. Look the engineer up on the TBPELS PE roster search. Confirm the license is active and the name matches the one on the report.
3. Ask about independence. Ask whether the engineer or firm receives work or payment from repair companies, and whether they'll inspect the repair and write the final letter if you hire a company they didn't pick.
4. Ask what the fee covers: the evaluation, an elevation survey, a written report, a repair design for permitting, post-repair inspection and final letter. These are often priced separately.
5. Read the report. It should carry the engineer's seal and signature, describe what was observed and measured, and state its limits.

The Texas Section of the American Society of Civil Engineers publishes guidelines for evaluating and repairing residential foundations, written by engineers for engineers. It's fair to ask an engineer whether they follow them.

What it costs

HomeAdvisor's foundation repair cost guide (updated June 20, 2026) puts a structural engineer's inspection at $340 to $780. That is a national figure, not a Collin County quote. A repair design, post-repair inspection and final letter can be separate fees, so ask for the total for the whole job. For how this fits into a full repair budget, see the cost guide.

This guide refers homeowners to foundation repair companies, not to engineers. Once you have an engineer's report, you can ask for bids through how it works.
