Built for San Diego
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 Diego County building department handles site permits, foundations and utility connections.
Seismic
Foundations and anchorage are designed for the local seismic design category.
Coastal air
Corrosion-resistant fasteners, coatings and HVAC components for salt air.
Buy, lease or rent
Choose the option that fits

| Lease | Multi-year needs without a large up-front cost; classroom and office expansions |
