Where are Wind Zone 2 and Wind Zone 3 for mobile homes located?
Tuesday, October 2, 2018
The three wind zones for mobile homes are noted with Roman Numerals: I, II, and III. Most of the U.S. is in Zone I, with coastal and southern, hurricane-prone areas upgraded to Zones II (rated to withstand 100-mph winds) and III (up to 110-mph winds). See the map below for a general idea of the location of each zone.
All of the counties in Florida are in Zone II, except the following Zone III counties, which are primarily South Florida, plus two counties at the bump-out in the Panhandle Gulf coastline: Broward, Charlotte, Collier, Dade, Franklin, Gulf, Hendry, Lee, Martin, Manatee, Monroe, Palm Beach, Pinellas, and Sarasota.
You should expect to pay several thousand dollars per step to upgrade to each higher wind zone. And, although you can’t place a mobile home constructed to Zone I standards in Zone II, you can upgrade to higher than the required rating: Zone II homes can be sited in Zone I (although there is no Zone I in Florida), and Zone III homes can be put in Zone II.
Want a sturdier mobile home? Upgrade to the next higher wind zone rating. If you are checking out a used mobile home, the wind zone rating is noted on the home’s data plate.

There is also a special category for manufactured homes to be sited within 1500 feet of the coastline in hurricane-prone areas of the country. It’s called a “D-sticker” home, and means that it has been designed to meet the wind resistance requirement of ASCE 7-88, Exposure D—which is a standard referenced in the HUD Code.
