Metal building contractors in Guadalupe County, Texas

The Guadalupe County Fire Marshal Office, 830-303-8856, in the unincorporated county. The order adopts the 2024 International Fire Code with Appendices A through N, effective February 1, 2026, and defines a multi-family dwelling as four or more units and substantial improvement as work costing more than 50 percent of the building value or touching 30 percent or more of the original square footage (county order, checked 2026-09-13).

Those three types are the whole reach of the order. Texas gives a county no general commercial building code, and a fire code is the one county power that reaches a commercial building, open only where the county population tops 250,000 or the county borders one that big. County against city: 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 exempts the ones it names, and the wording is narrow. The order does not apply to an agricultural building used specifically to produce or process food products, shelter livestock, or shelter tools and equipment essential to a farm or ranch operation, and it does not apply to an industrial facility with a fire brigade conforming to Occupational Safety and Health Administration requirements (county order, checked 2026-09-13). Use is what the clause turns on, not acreage.

It also stops at the fire code. The septic, floodplain and driveway permits run through other offices and none of them reads that clause, and a clear span over 24 feet puts the roof supporting members under the state engineering chapter either way.

Thirty calendar days is the outside limit and the clock has teeth: no decision within 30 days of a complete application and the fees, and the project is approved for the purposes of the order. Four drawings go with it, filed at the Development Center, 310 IH-10 West in Seguin: a floor plan showing exits, an elevation plan, an electrical plan showing the panel, and a site plan showing every structure and the nearest fire hydrant. At $50,000 of estimated construction cost the state step comes first, because a permitting official may not accept the application without verifying TDLR registration: the TDLR sheet.

The county values a project at $75.00 per square foot where construction cost is in question, a project valued under $6,250.00 pays a flat $200.00 plus a technology fee, and a separate building permit is required for each structure. From the fee schedule effective February 1, 2026 (Guadalupe County Appendix A fee schedule, checked 2026-09-13):

• Plans review, a $100.00 minimum.

• The building permit and inspection, covering a minimum of three construction site visits.

• Final inspection with certificate of compliance, $125.00.

• Site preparation and foundation, a $500.00 permit of its own.

• A permit renewal for a further 180 days, $200.00, where work has not started in the first 180.

Close to half of it is deep clay. Houston Black-Heiden on uplands is about 22 percent of the county with shrink-swell rated very high, and Branyon-Barbarosa-Lewisville, deep clayey soils on broad ancient stream terraces, is another 23 percent (USDA Soil Survey of Guadalupe County, Texas, 1977, checked 2026-09-13).

The rest is not clay. Crockett-Demona-Windthorst is the largest association at about 33 percent, loamy to sandy upland known locally as mesquite land, and about 13 percent is Patilo-Arenosa, the deep sands called the sandhills. Rock shows up in the west, where the Austin Chalk is exposed on the upthrown sides of faults in contact with the Taylor Marl (Texas Water Development Board Report 19, checked 2026-09-13). Two tracts a few miles apart can need two different foundations: the slab and foundation sheet.

Not on the TCEQ program county list. The Edwards and associated limestones sit under Guadalupe County only in the subsurface (Texas Water Development Board Report 19, checked 2026-09-13). In the San Antonio region the TCEQ Edwards Aquifer program names Bexar, Medina, Comal, Uvalde and Kinney, and Guadalupe is not among them (Texas Commission on Environmental Quality, Edwards Aquifer Protection Program, checked 2026-09-13). Balcones faults cut the northwest, Luling-Mexia faults the east and south.

A floodplain development permit from the Environmental Health floodplain manager, 830-303-8858, comes before new construction, an addition or any activity inside the regulated floodplain, and the county counts grading, filling, paving, excavation and drilling as development. It is $300 and construction has to start within 180 days. One acre of disturbance adds TCEQ construction general permit coverage, and five acres makes it large construction with a $225 electronic Notice of Intent.

Septic has no acreage escape here. The county requires an on-site sewage facility permit whatever the lot size or acreage, and a License to Operate is held before a system is built, altered, extended or operated. Environmental Health charges $600 for a commercial, multi-unit or rental community system, and building without the permit is fined double the permit fee. The county authorized agent covers everywhere except the City of Marion, while Seguin, New Braunfels and San Marcos hold their own jurisdiction.

Power starts early: Guadalupe Valley Electric Cooperative asks three to five weeks from request to connection and charges builders a $6,000 engineering deposit applied toward the final invoice (the septic, water and power sheet has the order of those calls). Road and Bridge, 830-379-9721, charges $100 for a private or temporary driveway simple crossing and $500 for a commercial driveway, doubled where work starts first, and a new access onto a state highway is TxDOT Form 1058 at the San Antonio District, 210-615-1110.

City limits hand the permit to the city, and these four towns do it four ways (city pages, checked 2026-09-13, linked under the permit stack below).

• Seguin takes the application to the Building Official, runs the 2021 International Building Code and the 2018 International Fire Code, prices permits by square footage under Texas House Bill 852 without publishing the amounts, and registers contractors first, 830-401-2435. The corridor rule on metal walls, the plat rule and the ground inside the city are on the Seguin metal building sheet.

• Schertz reviews plans in the city and its extraterritorial jurisdiction, quotes 30 days for an initial commercial review and 14 days for each one after, and permits an accessory building of 120 square feet or larger, 210-619-1750. The wall offset rule for commercial steel, the height cap on backyard buildings and the three-county split of the city are on the Schertz metal building sheet.

• Cibolo wants a pre-application conference before a commercial submittal, runs site plan review for a minimum of 45 business days, and asks for a TDLR registration number over $50,000.00, 210-658-4175. The backyard height caps, the street-front roof rule and the Branyon clay under the city are on the Cibolo metal building sheet.

• Marion uses a third-party inspector and names no code edition, 830-914-2391.

Ask who files the four drawings with the County Fire Marshal inside the 30-day clock, because a complete application and the fees start it and no decision in that window approves the project for the purposes of the order (Guadalupe County Commissioners Court order, checked 2026-09-13). Then ask who seals the foundation plan for a tract that may be very high shrink-swell clay or deep sand.

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 behind that title, which the San Antonio and Bexar County permit sheet states once for the whole footprint. Neighbors differ: Bexar County permits through Public Works and its Fire Marshal, Wilson County through a development permit. The build order is in the start-to-finish San Antonio guide; the types here are commercial steel buildings and metal shop buildings.
