Built for San Francisco
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 San Francisco County building department handles site permits, foundations and utility connections.
Seismic
Foundations and anchorage are designed for the local seismic design category.
Rain
Roof drainage, sealed envelopes and covered entries keep buildings dry through wet seasons.
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 |
