I didn't know that. Probably more homes have been built to that code in Miami/Dade than have been built in New Orleans. But I didn't even know it was possible to think a home could be built to withstand a Cat. 4 hurricane.
I've been thru Andrew and two cat 5's overseas (Guam and Okinawa). We had CBS construction in all 3 and faired well.
We put on an addition a couple years ago, and we had to bring the entire house up to Miami/Dade code (we're in Pinellas and that's the building code our county has adopted.) Everything from windows to doors, hurricane straps for the roof, etc. is rated for a Cat 4, but like I said, whether it will work or not hasn't been proven.
