Who reviews house plans in Galveston County?
Coastal construction adds layers most inland buyers never see. Expect floodplain review, finished floor elevation requirements, and in many areas a coastal construction setback. The windstorm process runs in parallel with the building permit and has to start before construction, not after.
What is the soil like in Galveston County?
Coastal soils with high water tables and, on the island, significant elevation requirements. Pier and beam or elevated construction is common and often required.
Does Galveston County require windstorm certification?
The entire county is in the TDI designated catastrophe area. You file a WPI-1 before construction, get inspections during the build from either a free TDI inspector or a TDI appointed Texas PE, and the resulting WPI-8 certificate is what makes the structure eligible for TWIA wind and hail coverage.

US Census Bureau, Building Permits Survey, 2025. Permit values are what builders declare and usually run below the full cost to build.
We do not publish a cost per square foot. Every plan page gives the Census line for a lot ZIP's county, and a local builder prices the plan for your lot.
Will the plan fit the lot
Every plan page draws the smallest lot the house fits on with typical setbacks: 5 ft each side, 25 ft front and 20 ft rear, plus 20 ft to turn into a side entry garage. The plans filter takes a lot width and shows only the plans that fit it. Setbacks, easements and deed restrictions vary by city, subdivision and county. Check yours before you buy. In Galveston County, ask the city, the subdivision or its HOA for the recorded setbacks and deed restrictions before you buy.
