Frisco’s houses are young
Census figures put the median Frisco home’s construction year at 2009. Of its 80,353 housing units, 82% were built in 2000 or later and just 2% before 1980. Single-family detached houses make up 69% of the city’s housing.
A young house changes the questions you ask about a crack:
- Is it still settling in? New houses shrink as framing lumber dries. The Foundation Performance Association lists drywall tape and crown molding separations in new houses among the things mistaken for foundation movement, and suggests waiting approximately two years for that shrinkage to settle before repairing.
- Is it a slab curing crack? If the slab is post-tensioned, FPA says early surface cracks from curing typically close once the cables are stressed, and no repair is usually required.
- Is it movement? Cracks that grow, doors that start binding and floors that slope together are the pattern to take seriously. The warning signs page has the full list, with lookalikes.
If the builder may owe the repair
Before you pay for a repair on a newer house, find your closing documents. Many new homes come with a written builder’s warranty, sometimes backed by a third-party warranty company, and any structural coverage in it will have its own claim steps and deadlines. Read it before anyone drills a hole, because unapproved repairs can complicate a claim.
If you end up in a dispute, Texas’s Residential Construction Liability Act sets the steps. It covers builders and repair contractors. Before suing over a construction defect, a homeowner must send the contractor written notice by certified mail at least 60 days beforehand, and the contractor gets a chance to inspect within 35 days of receiving it. That’s information, not legal advice; a lawyer who handles construction claims can tell you how it fits your house.
An independent engineer’s report is useful here. It records what moved and why, from someone with no stake in the repair or the warranty. The inspection page explains the levels of report and what each costs.

What Frisco’s engineers say about its ground
Frisco’s own engineering standards, updated in October 2025, treat the city’s subgrade as one of two formations, Eagle Ford and Austin Chalk, and require swell testing on both before streets are built. The rules show how much the city expects that ground to move:
| Frisco requirement for street subgrade | Why it matters for a house |
|---|---|
| Moisture treatment deep enough to hold potential vertical rise to 4.5 inches | The city plans for its soil to swell that much |
| Weathered Eagle Ford shale within 8 feet of the surface dug out and replaced | Weathered shale is treated as unfit to build on as it is |
| Double lime treatment for soils with more than 6,000 ppm of sulfates | Sulfates complicate the usual lime treatment |
A 2022 regional presentation by McKinney’s engineering director lists Frisco among three area cities that require moisture conditioning of subgrade. Houses don’t get that treatment once they’re built, which is why the slab design, the drainage and the watering do the work instead.
Older soil surveys add the west side’s story. The USDA’s 1930 survey of Collin County put the largest areas of one soil (Bell clay, high-terrace phase) along the county’s western edge between Celina and Frisco. Bell clay is a black clay the survey called very similar to Houston black clay, the county’s most common soil.
Frisco’s permit: stamped letter and pier drawings
Frisco wants an engineer involved from the start. Its residential alteration submittal requirements call for a stamped engineer’s letter and stamped pier drawings with the application, and the engineer must provide an inspection report when the repair is complete. The permit fee is $75.00.
For you, that means two things. A quote should say who hires the engineer and whether the letter, drawings and final report are in the price. And when the work is done, you should get copies of all three, plus the permit number. The permit guide compares Frisco with McKinney, Allen and Plano.

Watering in Frisco
Frisco’s watering schedule is tighter than most. Sprinklers run once per week, on your trash day, with a second day in summer, and the city bans watering 10 a.m. to 6 p.m. from April 1 to October 31. The exception that matters for foundations: hand-held hoses with a shut-off nozzle, soaker hoses, drip and bubblers can be used when needed, no more than 2 hours per day.
A soaker hose run along the dry sides of a slab in a long summer fits within that. The watering guide covers placement and how to tell when you’re overdoing it.
Getting a Frisco house inspected
Call or send a request, and a local foundation contractor who serves Frisco confirms a time, inspects and measures the floor, and gives you a written plan and price. If the house is under a builder’s warranty, say so when you call. Work is done by independent local contractors. Pricing and availability are set by the contractor serving your area.
