Metal Building Contractor in San Antonio
Veteran-owned steel building construction in San Antonio, TX — design, engineering, permitting, foundation and erection under one contract.
Typical turnkey cost
$60–$150
per sq ft, turnkey
That is the all-in range: foundation, erection, insulation, electrical, doors and permitting. Shell-only advertisements quote $22–$40 per sq ft for the steel alone, and the finished building typically lands three to four times that — which is where most first-time budgets go wrong. Your number depends on size, site and finish level, and we quote it line by line.
What We Build in San Antonio
San Antonio metal building work runs to distribution and manufacturing along the I-35 and I-10 corridors, military-adjacent service and support facilities, and a large volume of agricultural and ranch structures in the surrounding counties. It is a market where a single project may sit inside the city, in unincorporated Bexar County, or in a neighboring county — and the review path is different in each.
San Antonio is roughly four and a half hours from our Richardson office. Projects there are mobilized on a project basis with the cost stated openly in the estimate.
Permitting & Code in San Antonio
Who issues the permit
Inside the city, permits are issued by the City of San Antonio Development Services Department. Outside it, Bexar County reviews under its own Rules for the Enforcement of the International Fire Code and International Building Code, and the county does not enforce San Antonio's local amendments. Establishing which jurisdiction a site falls in is the first question on any San Antonio project, because it changes the amendments that apply.
Which code applies
San Antonio has adopted the 2021 International Building Code, 2021 International Residential Code and 2020 National Electrical Code with local amendments. Bexar County references the 2021 International Code series with its own county rules and amendments, not the city's.
What drives the engineering
South Central Texas brings its own foundation problem. Parts of Bexar County have expansive clay and parts have shallow rock, sometimes on the same site, and the two demand opposite foundation solutions. That makes a geotechnical investigation less optional here than almost anywhere else we work. Sun exposure and cooling load also push insulation specification harder than the code minimum on any conditioned building.

San Antonio Metal Building Questions
Yes, and which office issues it depends on where the site sits. Inside the city, the City of San Antonio Development Services Department issues the permit. In unincorporated Bexar County, the county reviews it under its own Rules for the Enforcement of the International Fire Code and International Building Code — and the county does not enforce San Antonio's local amendments. Confirming jurisdiction is the first step, because it changes which amendments the plans are drawn to.
The City of San Antonio has adopted the 2021 International Building Code, 2021 International Residential Code and 2020 National Electrical Code with local amendments. Bexar County references the 2021 International Code series with county rules and amendments of its own rather than the city's.
Bexar County soils are genuinely mixed — expansive clay in some areas, shallow rock in others, occasionally both on one site. Those two conditions call for opposite foundation designs, which is why a geotechnical investigation matters more here than in a market with uniform soils. Designing a San Antonio slab without one is a gamble on which half of the county you are standing in.
Yes. Equipment barns, hay storage and covered working facilities in the counties around San Antonio are a regular part of our metal building work. Rural sites are usually reviewed by the county rather than a city, which typically means a shorter permitting cycle than an in-city commercial project.
