Built for St. Louis
Local conditions, codes & permits
Every building is specified for where it will sit. In most states, commercial modular buildings are built to the same building codes as site-built structures and inspected at the factory under a state program or third-party agency, while the city or St. Louis County building department handles site permits, foundations and utility connections.
Snow load
Roofs are specified for the local design snow load, with skirting and entries planned for drifting snow.
Cold
Higher insulation values, cold-rated HVAC or heat, and freeze-protected plumbing keep buildings usable all winter.
Heat
HVAC sized for summer peaks, extra insulation, reflective roofing and shaded entries keep buildings comfortable and efficient.
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 |
