Ground-up commercial, tenant build-outs and franchise locations in San Antonio, TX — estimating, permitting, construction and closeout under one contract.
What We Build in San Antonio
San Antonio commercial work runs to distribution and manufacturing along the I-35 and I-10 corridors, military-adjacent service and support facilities, and a steady retail and restaurant build-out market. Projects frequently sit inside the city, in unincorporated Bexar County, or in a neighboring county — and the review path differs in each.
San Antonio is roughly four and a half hours from our Richardson office, mobilized on a project basis with the cost stated 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 jurisdiction is the first question on any San Antonio project.
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 rather than the city's.
What drives cost and schedule
Which jurisdiction a site falls in changes the amendments a plan is drawn to, so it has to be settled before design rather than at review. On ground-up work, Bexar County soils are genuinely mixed — expansive clay in some areas, shallow rock in others, occasionally both on one site — which makes a geotechnical investigation matter more here than in a market with uniform soils.
