Metal building contractors in Wilson County, Texas

Permitting and Development, 800 Tenth Street, Bldg B, Floresville, 830-393-8357. It publishes three permits: development, septic and driveway. No page checked on the county site names a county building permit for a commercial or accessory structure as such, and no page checked states an adopted building code edition (Wilson County, Permitting and Development, checked 2026-09-13).

Read that as a list, not a pass. Texas gives a county no general commercial building code, so the missing page is normal. The one county power that reaches a commercial building is a fire code, and Wilson adopted one in 2025. County against city is in the San Antonio and Bexar County permit sheet.

Whole chapter checked; it gives counties no such power. Checked at Texas Legislature Online, Local Government Code Chapter 233, county regulation of housing and other structures, 2026-09-13.

It is the commercial trigger inside a routine application. The packet also requires a drainage study on a footprint of three acres or more, and an elevation certificate in a Special Flood Hazard Area. The authorization to construct runs twelve months, and a new application and fee are due if no final inspection happens in that year (Wilson County development permit packet, checked 2026-09-13).

Commissioners Court signed an order on October 27, 2025 adopting the 2021 International Fire Code in its entirety, citing Health and Safety Code Section 775.036 as the county authority, and the Fire Marshal Office is at 802 10th St., Floresville, 830-259-5612. Under Local Government Code Chapter 233, a county fire code reaches three kinds of building (commercial establishments, public buildings, and multifamily residential dwellings of at least four units), and only a county of more than 250,000 people, or one bordering a county that size, may adopt one. The certificate at the end of the job is a county fee line, not a guess: the Fire Marshal fee schedule prices a commercial building permit as plan review, inspection, and final inspection or certificate of compliance (Wilson County Fire Marshal Appendix A fee schedule, checked 2026-09-13).

Square footage sets it. The county calculates project valuation at $75.00 per square foot, a project valued under $6,250.00 pays a flat $200.00, and at that rate a small shop clears the flat-fee line fast. The $50,000 mark is a separate clock, in the TDLR sheet. The permit itself is three fees (Wilson County Fire Marshal Appendix A fee schedule, revised November 30, 2025, checked 2026-09-13):

• Plan review, a $100.00 minimum.

• Inspection, covering a minimum of three construction site visits.

• Final inspection or certificate of compliance.

It changes field to field, and none of it is rock. The soil survey splits the county three ways: Wilco-Floresville-Miguel at about 35 percent, sandy and loamy over clayey lower layers, slowly permeable; Eufaula-Patilo at about 20 percent, deep sand that drains nothing like the clay nearby; and Elmendorf-Luling-Denhawken at about 15 percent, where the survey names shrink-swell and corrosivity to uncoated steel pipe (USDA Soil Survey of Wilson County, Texas, 1977, checked 2026-09-13).

There is no limestone shelf to bear on: sand, silt and clay from Eocene to Recent, dipping southeast about 150 feet per mile and cut by many normal faults (Texas Board of Water Engineers, Bulletin 5710, checked 2026-09-13). Design the foundation off a soil report for that tract, not the last job two roads over: the slab and foundation sheet.

Into a county determination, $100.00, rising to $300.00 inside a Special Flood Hazard Area, plus a $500.00 drainage review and a $200.00 elevation certificate review when they apply. A newer fee list effective May 11, 2026 does not render as readable text, so confirm amounts on 830-393-8357 (Wilson County fee sheet, March 1, 2022, checked 2026-09-13).

Acreage adds a state layer: one acre or more of disturbance needs TCEQ construction general permit coverage, five acres or more a Notice of Intent. Wilson is not among the San Antonio-region Edwards Aquifer counties TCEQ names.

Septic is a county permit, and a metal building counts as commercial: state rule treats any building that is not a single-family dwelling or duplex as commercial, and an engineer or sanitarian seals the planning materials for non-standard treatment. The Wilson County authorized agent on the TCEQ record covers the unincorporated county only and the record does not say who permits inside the cities, so a city address is confirmed with that city, and the county fee is $400.00 for a commercial or alternative system (county fee sheet, checked 2026-09-13).

Power starts with a questionnaire and a 911 address; Karnes Electric Cooperative serves 12 counties including Wilson. The order is in the septic, water and power sheet. The way in is its own permit: onto a county road the PIPROW permit, $750.00 for a commercial driveway of 24 to 100 feet; onto a state highway Form 1058 to the TxDOT San Antonio District, 210-615-1110.

City limits hand the permit to the city, and the four towns here answer differently (city pages, checked 2026-09-13, linked under the permit stack below).

• Floresville charges a permit fee on new building, additions, remodels and alterations, residential or commercial, by declared valuation, adopted the International Building Code and the International Residential Code without naming an edition year, and prices fire code plan review at $500.00 and inspection at $750.00 to a $250,000 valuation. Buildings and Permits, 830-393-3105.

• La Vernia publishes a Commercial Building Packet and a separate Residential Accessory Building packet, uses the 2018 International Building Code and the 2021 International Fire Code, and sends plan review and field inspections to one outside company, 830-779-4541.

• Stockdale and Poth are incorporated too, and no permit page was read for either.

The Wilson question to ask a bidder first is who takes the fire safety meeting to the county Fire Marshal, because the development permit is not approved for a commercial structure until that meeting is scheduled (Wilson County development permit packet, checked 2026-09-13). Then ask who seals the foundation plan for ground that runs from deep sand to shrink-swell clay inside one county line.

Each request lands with one independent metal building contractor, who picks which jobs to take on and prices those, and Texas issues no builder license to check first, which the San Antonio and Bexar County permit sheet covers once for the whole footprint. Neighbors differ: Guadalupe County permits a commercial building under a county fire code order, Karnes County its own stack. The build order is in the start-to-finish San Antonio guide; the common types are commercial steel buildings and metal shop buildings.
