Foundation Repair in Galveston, TX

The island's water history and the sinking ground around it

Galveston once drew all of its water supply from groundwater wells. A 1984 U.S. Geological Survey report for the state says that until late 1973 the City of Galveston depended entirely on wells in the Alta Loma area, pumping about 13 million gallons a day, then began buying surface water from Lake Houston; by 1978, groundwater pumping in that area had fallen to 2.7 million gallons a day (Report 287, Ground-Water Withdrawals and Land-Surface Subsidence in the Houston-Galveston Region, 1906-80 (USGS for the Texas Department of Water Resources, 1984), state agency report, checked 2026-10-17). The same report describes a center of subsidence in the Texas City area, where local groundwater withdrawals caused as much as 6 feet of land sinking. The Harris-Galveston Subsidence District tells the same story from its side: by 1973 the City of Galveston, working with the City of Houston and the Coastal Water Authority, had started switching to Lake Houston water, and in May 1975 the Legislature created the District (Harris-Galveston Subsidence District, Our History, checked 2026-10-17). Today it regulates groundwater pumping in Harris and Galveston counties and publishes an interactive subsidence map from satellite and GPS data (Harris-Galveston Subsidence District, checked 2026-10-17). That history describes land across a region, not your lot. A cracked slab on the island still needs its own evaluation.

City of Galveston permits for foundation repair

• When a permit applies. The City's permitting FAQ says a project valued at $500 or more will typically need a permit. Valuation means all labor and materials, with no discount for donated materials or your own labor; paint, new flooring, cabinets and interior trim are given as examples that don't need one (City of Galveston, Building Codes & Permitting, checked 2026-10-17).
• Who is responsible. The City says the property owner is responsible for getting all required permits, that construction without one brings double or triple permit fees and may lead to Municipal Court action, and that questions go to the Building Division at (409) 797-3620 (City of Galveston, Applications, Fees, and FAQs, checked 2026-10-17).
• Engineering. "Engineering is required on all structural projects within the City of Galveston," the City says. It suggests an engineer from Galveston County for local familiarity but says owners are free to use whomever they want (City of Galveston, Contractors & Engineers, checked 2026-10-17).
• On the job site. Permits must be displayed where they're visible from the street, with the plan set the City reviewed kept on site; missing either can bring a Red Tag violation with a fee of at least $50. The City says it has adopted the 2021 International Residential Code (City of Galveston, Building Inspections, checked 2026-10-17).
• Inspections. The City's residential inspection list includes a foundation inspection, and requests are made through the City's ePortal or by email (City of Galveston, Building Inspections, checked 2026-10-17).
• Where to apply. Building permit applications go through the City's ePortal (City of Galveston, Development Services, checked 2026-10-17).

Contractor registration with the City

The City's contractor registration asks for a $200 fee, a $25 annual fee, liability insurance of at least $300,000 naming the City as additional insured, and an original surety bond of at least $25,000 (City of Galveston, Contractors & Engineers, checked 2026-10-17). That's a City requirement, and SteadyHomeHouston doesn't check whether a contractor is registered; ask the Building Division.

Historic districts

Development Services lists East End, Lost Bayou, Strand/Mechanic and Silk Stocking under historic preservation, and its applications page includes a Landmark Commission Certificate of Appropriateness (City of Galveston, Development Services, checked 2026-10-17; City of Galveston, Applications, Fees, and FAQs, checked 2026-10-17). If your house is in one of those districts, ask the City before foundation work starts.

Flood rules and big repairs

The City's Flood Damage Prevention Ordinance (No. 18-032) requires a Floodplain Development Permit to make sure work conforms with it. It defines "substantial improvement" as work costing 50 percent or more of a structure's market value before the work starts, and "substantial damage" as damage that would cost 50 percent or more of that value to restore (City of Galveston, Flood Damage Prevention Ordinance, checked 2026-10-17). This is the ordinance posted on the City's site; ask the Building Division whether it has been amended. For new construction and substantial improvements, it requires anchoring against flotation, collapse or lateral movement, and flood-resistant materials and methods. If a foundation job is large relative to your home's value, ask the Building Division whether those rules apply before you sign.
