Texas's dominant soil condition is expansive clay, which swells when wet and contracts when dry, creating significant foundation movement. Post-tension slab foundations are standard in most of the state's major metros, adding $1-3 per square foot over conventional slabs. In the Houston area, high water tables can require pier-and-beam construction or extensive drainage systems. Sandy soils along the Gulf Coast may need compaction or soil stabilization for structural support. Foundation repair is a major industry in Texas, as the Dallas and Houston areas lead the nation in foundation repair claims driven by cyclical drought-and-rain patterns in clay soils.

Structural wind resistance requirements in Texas vary dramatically by location. Coastal counties within the Texas Department of Insurance Windstorm Inspection Program zone require WPI-8 inspections and certification for all structural connections, from foundation anchor bolts through roof framing. The Texas Windstorm Insurance Association (TWIA) requires compliance with building standards before offering wind coverage. Inland areas generally follow IRC prescriptive wind design for 90-110 mph basic wind speeds. Tornado shelters conforming to ICC 500 or FEMA P-320 are increasingly incorporated into new residential construction throughout Tornado Alley areas of North Texas.
