Built for San Antonio
Local conditions, codes & permits
Every building is specified for where it will sit. Commercial modular buildings in Texas are built to the same codes as site-built structures and inspected under the state's industrialized building program, while the City of San Antonio or Bexar County handles site permits, foundations and utility connections.
Texas heat
HVAC sized for 100°F+ summer days, added insulation, reflective roofing and shaded entries keep buildings comfortable and efficient.
Expansive clay soils
Much of North and Central Texas sits on clay that swells when wet and shrinks in drought. Blocking, piers or foundations are engineered for the soil, and units can be re-leveled if the ground moves.
Buy, lease or rent
Choose the option that fits
| Option | Best for |
|---|---|
| Rent | Short projects, events, construction sites and temporary overflow |
| Lease | Multi-year needs without a large up-front cost; classroom and office expansions |
| Lease-to-own | Growing organizations that want to own later (where available) |
| Buy | Long-term or permanent use; usually the lowest total cost over time |
