California is its own beast. Container homes are legal but the path depends on county. Rural counties like Kern or Modoc? Easy. Treat it like any building. Standard permit. Central Valley like Fresno or Sacramento? Moderate. They want engineered plans and energy compliance docs but it goes through. LA, Orange County, Bay Area? Hard mode. Coastal restrictions and design review boards. Your best bet there is the ADU route. California passed AB 68 and AB 881. A container home under 1,200 sq ft on a single family lot often qualifies for fast track approval. The energy code is strict here. Title 24 means R-19 wall insulation, R-38 roof, double pane low-E windows, high efficiency HVAC. Our insulated models meet those numbers. For seismic most of California is Zone 4. Steel handles earthquakes well because it flexes instead of cracking. You just need engineered foundation plans with tie-downs. Send me your county and I will tell you what other buyers did. info@atvworldwide.com.
