Short answer
Frisco requires a residential building permit for foundation repair, with a stamped engineer letter and stamped pier drawings, and the engineer must provide an inspection report when the work is finished. The city's fee schedule lists $75 for a foundation repair permit plus a $50 non-refundable application fee. About 34% of Frisco's land is Houston Black clay, and another 30% is Heiden or Branyon, both high shrink-swell clays.
Frisco at a glance for foundations
Frisco is young: nearly half its homes were built in 2010 or later. Its soils are also different from the older cities to the east. Plano and Allen sit mostly on Houston Black clay and chalk-derived soils; Frisco has a much bigger share of Heiden and Branyon clays. None of that tells you anything about a particular house, but it does shape the questions worth asking. This page covers what is specific to Frisco. For a diagnosis of your home, you need a Texas-licensed professional engineer.

The soil under Frisco
We calculated soil shares for land inside Frisco's city limits from the USDA's Collin County soil survey (NRCS Web Soil Survey; data pulled through Soil Data Access, survey area TX085). The result:
- Houston Black: about 34%
- Heiden: about 18%
- Branyon: about 12%
- Austin: about 12%
- Stephen: about 6%
- Eddy: about 4%
A lower Houston Black share doesn't mean gentler soil. Heiden is classified in the same clay family as Houston Black, with high shrink-swell potential and cracks up to about 3 inches wide at a foot deep in dry periods (USDA Heiden series description). Branyon is a clay formed in alluvium on old stream terraces, and like Houston Black, the USDA notes that water enters it rapidly when it is dry and cracked and very slowly when it is moist (Branyon series description). Together, Heiden and Branyon cover about 30% of Frisco's mapped land, more than in any other city this guide covers.
The Austin, Stephen and Eddy soils formed over chalk and are thinner, with lower shrink-swell ratings in the USDA's engineering data. Soil maps can't resolve a single lot, so treat these as a picture of the city, not of your yard.
Permits for foundation repair in Frisco
Frisco's Residential Alteration Submittal Requirements (Form 4038, February 2026) has a foundation repair section:
- Apply online with a Residential Building Permit Application (Other Home Improvements).
- Upload a stamped engineer letter and stamped pier drawings in PDF format.
- The engineer must provide an inspection report at the time of completion, emailed to the city's building inspections address listed on the form.
- Some subdivisions require HOA approval, so check with your HOA.
Fees. Frisco's consolidated permit fee schedule lists $75 for a foundation repair permit and a $50 non-refundable application fee for residential permits. Fee schedules change, so confirm the amount when applying.
Contractor registration. Frisco's contractor registration page says contractors must be registered before most permits can be submitted, and lists general contractors and the engineer of record for residential structural and foundation work among the trades that must register. Registration is tied to proof of insurance and gives a registration number. It is a city requirement, not a state license; Texas has no license for foundation repair contractors.
For permit questions, Frisco lists Customer Service, Plans and Permits at 972-292-5301 (Residential Permits).
Frisco's housing age
The Census Bureau's American Community Survey puts the median year built for Frisco homes at 2009 (ACS 2020 to 2024, table B25035). The breakdown (table B25034) shows about 47% of homes built in 2010 or later, about 35% in the 2000s, and fewer than 5% before 1990.
In general terms, that makes Frisco a city of relatively new slabs. For many owners the first questions are about the builder: what the written warranty covers, when it expires, and how claims must be made. Read the warranty and note any deadlines before paying for outside repairs. Frisco's PTI report requirement is a clue that many of these newer homes sit on post-tensioned slabs. The Post-Tensioning Institute explains that the steel tendons put the concrete in compression to resist the stresses that shrinking and swelling soil creates (PTI on slab-on-ground foundations). Those tendons are under high tension, so anyone planning to cut or drill into the slab should know first whether it is post-tensioned. Our slab foundation repair page explains how slab repairs generally work.
Watering foundations in Frisco
Frisco's Water Efficiency Plan sets a seasonal sprinkler schedule tied to your regular trash day:
- Spring (April 1 to May 31) and fall (September 1 to October 31): one day a week, on trash day.
- Summer (June 1 to August 31): two days a week, trash day plus a designated second day.
- Winter (November 1 to March 31): no spray or rotor watering of turf.
- No watering between 10 a.m. and 6 p.m. from April 1 to October 31.
The same plan allows a hand-held hose with a shut-off nozzle, soaker hoses, drip irrigation or bubblers when needed, for no more than two hours per day, and says runoff should not occur. The city's watering schedule page has the map for your assigned day. Frisco doesn't define a foundation zone the way Plano does, so our foundation watering guide covers placement in general terms. After the 2026 dry spell, when Collin County reached 79% extreme drought by September 22 (US Drought Monitor county data), check the city's current rules before changing your routine.
Getting a Frisco foundation evaluated
Frisco's permit process already requires a stamped engineer letter and a completion report, but those engineers may be hired through the repair company. You can hire your own engineer first. Texas's engineering board has said that analyzing the cause of a foundation problem and recommending repairs is the practice of engineering (TBPELS advisory opinion 43), so a free inspection from a salesperson is a sales visit, not an engineering opinion. Check any engineer's license on the TBPELS roster, and see our engineer report vs free inspection guide.

Frequently asked questions
Do I need a permit for foundation repair in Frisco?
Yes. Frisco's Form 4038 says to apply online with a Residential Building Permit Application (Other Home Improvements) and upload a stamped engineer letter and stamped pier drawings. The engineer must provide an inspection report when the work is complete.
How much is a foundation repair permit in Frisco?
Frisco's consolidated fee schedule lists $75 for a foundation repair permit plus a $50 non-refundable application fee for residential permits. Confirm with Plans and Permits on 972-292-5301 before applying, since fee schedules change.
Is Frisco's soil less expansive because it has less Houston Black?
Not necessarily. Our calculation from USDA soil data puts about 34% of Frisco's land on Houston Black, but another 30% is Heiden or Branyon, which are also high shrink-swell clays. Only an engineer can speak to the soil under a specific house.
Can I water my foundation outside my Frisco watering day?
Frisco's Water Efficiency Plan allows a hand-held hose with shut-off nozzle, soaker hoses, drip or bubblers when needed, for no more than two hours a day, with no runoff. Sprinklers follow the seasonal trash-day schedule.
My Frisco home is only a few years old. Where do I start?
Read your builder's written warranty and note any deadlines. Frisco requires a post-tension report or soils report for new-home foundations, so ask the builder for that paperwork. An independent Texas-licensed engineer can then evaluate the house.
