Florida container homes are absolutely legal but the building code is strict here. Florida follows the Florida Building Code which is one of the toughest in the country because of hurricanes. The good news: steel containers handle wind better than wood frame houses. Our units ship at 120 mph wind rating which covers most of Florida. The Panhandle and coastal areas need 140-160 mph rating which means impact windows and reinforced anchoring. Most Florida counties require a building permit. The process is: submit engineered plans, pass wind mitigation review, pass foundation inspection, pass final inspection. Counties like Polk, Lake, Marion, and Hernando are the most container-friendly. Miami-Dade and Broward are the strictest. Every container home in Florida needs a permanent foundation. Concrete slab minimum. Pier blocks work for temporary structures but not permanent dwellings. Flood zones require elevation above base flood elevation. If your land is in a flood zone factor in piling costs. Septic requires a percolation test and Department of Health approval. Most of our Florida buyers go through the permit process without major issues. Email info@atvworldwide.com and I will share what buyers in your county submitted.
