Alamo Metal Buildings

Metal building contractors in Medina County, Texas

Medina County publishes a list of exactly five permits it requires, and a building permit is not one of them: 911 addressing, water well, floodplain, septic, and driveway and utility (Medina County, What Type of Permits Are Required In Medina County?, checked 2026-09-13). That is what the county lists, not permission to skip everything else.

More on this

Septic, floodplain, an Edwards Aquifer plan on a regulated zone, stormwater coverage from one acre and TDLR registration at $50,000 all still land, and Hondo, Castroville, Devine and Lytle permit buildings inside their own limits.

Long white metal building beside a plowed field in Medina County, Texas

Which office signs off on a metal building in Medina County, TX?

Outside the cities, the county's list does not include one. A building permit for a commercial or accessory structure is not among the five numbered items, and no page checked on the county site names a building department, a code edition, a plan review or a certificate of occupancy (Medina County, checked 2026-09-13). Confirm before relying on it: 1100 16th Street, Hondo, 830-741-6000.

The Fire Marshal answer points the same way. That role is combined with Emergency Management at 925 Avenue Y, Hondo, and the permit content published there covers outdoor burning: no fire code edition, no plan review, no county building permit.

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.

What still applies when no county building permit does

The $50,000 line is the big one. Any building job with $50,000 or more in total estimated construction cost must be registered with TDLR, with the construction documents going to a registered accessibility specialist for review; under that, a project still complies with the Texas Accessibility Standards without registering. Stormwater runs on acreage, not county lines: one acre or more of disturbance needs coverage under the TCEQ construction general permit, five acres or more a Notice of Intent first. The full sequence is in the San Antonio and Bexar County permit sheet.

Is your Medina County site on the Edwards Aquifer?

Medina is one of the two counties on this site the aquifer program names. TCEQ requires an approved Edwards Aquifer protection plan before construction begins on the recharge, transition or contributing zone, and in the San Antonio region the program pages name Bexar, Medina, Comal, Uvalde and Kinney counties. Only portions are regulated, so TCEQ points to its map viewer for a specific site.

The approval comes before the dozer: TCEQ regulates clearing and excavation alongside buildings. The zones, the review clock and the acreage fees are in the Edwards Aquifer sheet; the other named county here is Bexar County, which does run a county building permit.

The ground under a slab in Medina County

It changes halfway down the county. The northern hills are shallow soil over fractured limestone: Tarrant soils carry about 16 inches of cobbly clay over bedrock, with coarse fragments covering 35 to 90 percent of the surface. South of the hills it is Rio Grande Plain, whose largest association, about 30 percent of the county, is deep loamy and clayey calcareous soil on broad, smooth uplands (USDA Soil Conservation Service, Soil Survey of Medina County, Texas, 1977, checked 2026-09-13).

Two sites 20 miles apart here can need two different foundations, so the soil report comes before the slab drawing, and Hondo asks for a sealed engineered foundation plan with a geotechnical survey or soil test. What the erector needs from the concrete is in the slab and foundation sheet.

Floodplain, septic, driveway, water and power: five offices

Two of them are one county office. Environmental Health in Hondo takes the floodplain development permit, required for any man-made change to real estate in the floodplain, filling, grading and paving included, and the septic permit, required for every on-site sewage system. The driveway is a third county answer, not a central office: the county permits driveways and utilities through the individual Precinct Commissioner (Medina County, checked 2026-09-13).

The state adds a designer rule on the aquifer: a professional engineer or a professional sanitarian seals the septic planning materials for all new construction on the recharge zone. A lot with no public or community water means a registered well through the Medina County Ground Water Conservation District, and a well into or through the Edwards Aquifer takes a $25 permit application to the Edwards Aquifer Authority first. Medina Electric Cooperative charges a non-refundable $100 engineering fee before the site visit and takes four to six weeks once a job goes to construction. The county list itself is five items, each with its own office (Medina County permit list and the county Environmental Health fee schedule, checked 2026-09-13):

  • 911 addressing, from the county 911 addressing department, 830-741-8997.

  • Water well, registered through the Medina County Ground Water Conservation District, 830-741-3162.

  • Floodplain development, from Environmental Health in Hondo, 830-741-6195, at $45.00.

  • Septic, from that same Environmental Health office, at $200.00 for a conventional system and $400.00 for an aerobic one.

  • Driveway and utility, from the Precinct Commissioner the property sits in: Precinct 1 on 830-741-6016, Precinct 2 on 830-931-4000, Precinct 3 on 830-741-6006, Precinct 4 on 830-665-8015.

What is different inside Hondo, Castroville, Devine and Lytle?

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

  • Hondo. The Non-Residential Permit Checklist asks for three copies of the construction and site plans, a sealed engineered foundation plan with a geotechnical survey or soil test, sealed engineered mechanical, electrical and plumbing plans above 5,000 square feet, and TDLR registration over $50,000.00, on the 2015 International Building Code. City Hall, 830-426-3378. The carport setback, the permit fee table and the Knippa clay under most of the city are on the Hondo metal building sheet.

  • Castroville requires a permit for any accessory structure over 200 square feet, naming carports, garages, sheds and storage buildings, and its exclusions pertain to residential permits only, so commercial work gets no exemption. Community Development, 830-931-4090. The Highway 90 rule on metal walls, the historic district review and the ground inside the city are on the Castroville metal building sheet.

  • Devine approves plans and collects all fees before issuing a permit, on the 2021 International codes effective March 1, 2024, and building without one doubles the fees. Code Compliance, 830-663-2804.

  • Lytle runs a Fire Marshal plan review and inspection on every commercial application before a certificate of occupancy, 830-709-3692.

  • Natalia is incorporated too, and no permit page was read for it.

Hiring metal building contractors in Medina County, TX

Ask first who holds the Edwards Aquifer approval where the site sits on a regulated zone, because Medina is one of the two counties on this site the TCEQ program names and nothing starts on the ground until that plan is approved. Then ask who seals the foundation plan with the geotechnical survey or soil test Hondo asks for by name (city pages, checked 2026-09-13), who prepares the septic planning materials, and what the bid assumes about the clocks.

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, and the San Antonio and Bexar County permit sheet carries that statewide picture. Start at commercial steel buildings or metal shop buildings, the build order is in the start-to-finish San Antonio guide, and the sheet south is Frio County.

Medina County, TX permits, row by row

Each permit and rule the county's own site posts for work outside city limits: who to call, the number, where it was checked and when.

Building permit outside city limits

Not on the county site

Medina County publishes a one-page list titled What Type of Permits Are Required In Medina County? It carries five numbered items: 911 addressing, water well, floodplain, septic, and driveway and utility. A building permit for a commercial or accessory structure is not one of them, and no page checked on the county site names a building department, a building code edition, a commercial plan review or a certificate of occupancy at the county level. Confirm with the county before relying on that, and note that a city inside the county runs its own permits.

Fire code

Not on the county site

Medina County's Fire Marshal role is combined with the Emergency Management Coordinator role and sits at 925 Avenue Y, Hondo. The permit content published on that page covers outdoor burning. The page states no adopted fire code edition and names no fire code plan review, no fire code inspection and no commercial building permit at the county level.

Each row comes off Medina County's own site, on the date printed beside it. None is copied from a neighboring county. A blank on the county site means the county posts nothing on that item; it does not mean a building goes up unregulated. The state $50,000 registration and the acre-based stormwater rules hold no matter what the county posts, and so do the six rules above that Medina County does post, each on the terms in its own row. Cities inside the county permit for themselves, so an address inside a city limit gets confirmed at that city hall; the only cities described here are the ones whose own pages were checked.

Medina publishes five permits for the unincorporated area and no building permit among them, while Atascosa County requires one before a new commercial building goes up. Both rows sit side by side on the seven-county permit office list, with the floodplain, septic and driveway office for each.

What owners ask

Is a building permit required for a metal building in Medina County, TX?

Outside the city limits, Medina County's own list of required permits does not include one. Its five items are 911 addressing, water well, floodplain, septic, and driveway and utility, and no page checked on the county site names a building department, a code edition or a county plan review. That is what the county lists, not a finding that a building there is unregulated. The county septic and floodplain permits, TCEQ stormwater coverage from one acre of disturbance, an Edwards Aquifer plan on a regulated zone and TDLR registration at $50,000 all still apply, and inside Hondo, Castroville, Devine or Lytle the city permits the building. Confirm on 830-741-6000. Checked at the county permit list and the TDLR Architectural Barriers pages, 2026-09-13.

Does Castroville require a permit for a metal storage building?

Castroville requires a permit for any accessory structure over 200 square feet, and the city names carports, garages, sheds and storage buildings as its examples. An accessory structure under 200 square feet is exempt only where it carries no electric, plumbing or mechanical work. The city states that its permit exclusions pertain only to residential permits and that all other zonings contact the Community Development Department, 830-931-4090, so commercial work is covered by no exemption. The page names the International Building Code and states no year edition. Outside the city limits the county list applies instead, and it carries no building permit. Checked at the Castroville permits and development page, 2026-09-13.

What do county permits cost in Medina County?

Medina County publishes four figures at its Environmental Health office in Hondo, 830-741-6195: a floodplain development permit at $45.00, a conventional septic system permit at $200.00, an aerobic septic system permit at $400.00 and a septic reinspection at $50.00. The county has adopted the 2020 FEMA maps and does not accept the older ones with either application. Driveway and utility permits come from the individual Precinct Commissioner rather than a central office and the county publishes no amount for them, so ask the commissioner for that precinct. Checked at the Medina County Environmental Health Group page and the county permit list, 2026-09-13.

Does a metal building in Medina County need an Edwards Aquifer plan?

It does where the site sits on a regulated zone. TCEQ requires an approved Edwards Aquifer protection plan before construction begins on the recharge, transition or contributing zone, and in the San Antonio region the program pages name Bexar, Medina, Comal, Uvalde and Kinney counties. Only portions are regulated, so being in Medina County does not answer it: TCEQ points to its own map viewer to settle a specific site. Clearing and excavation are regulated alongside buildings, so on the recharge zone the approval comes before site prep, whatever the county permits. Checked at the TCEQ Edwards Aquifer Protection Program pages, 2026-09-13.
