Subject: Wind Zone Requirements for Manufactured (Mobile) Homes and HUD Park Trailers

Advisory Date: 10/13/04 Implementation Date: Immediately

Advisory Number: MH04-01


This technical advisory supercedes TA# MH94-04 "Wind Zone Requirements for Manufactured/Mobile Homes and HUD Park Trailers," dated June 24, 1994.

In an effort to protect the safety and property of Florida residents living in manufactured/mobile homes, all new and used manufactured/mobile homes installed in Florida can only be placed or re-sited within the Wind Zone area for which the home was constructed and designated, as indicated on the data plate or other document(s) evidencing the Wind Zone construction designation.

In July 1994, the U.S. Department of Housing and Urban Development (HUD) amended the Federal Manufactured Home Construction and Safety Standards and subdivided the State of Florida into two (2) "Wind Zones;" Wind Zone II and Wind Zone III. Prior to that date all Florida was designated Wind Zone II.

The Florida counties that were included and continue to be included in the Wind Zone III designated area are: Martin, Palm Beach, Broward, Dade, Monroe, Collier, Hendry, Lee, Charlotte, Sarasota, Manatee, Pinellas, Gulf and Franklin. All other counties remain Wind Zone II designated counties (see the attached exhibit).

Existing manufactured/mobile homes built to Wind Zone II standards may only be initially placed or re-sited in a Wind Zone II area. Homes built to Wind Zone III construction standards may be initially placed or re-sited in any Wind Zone area in Florida. Any new or existing Wind Zone I designated homes may not be placed or re-sited anywhere in the State of Florida.

All homes installed within 1,500 feet of the coastline in Wind Zones II and III continue to be required to be designed for the increased requirements specified for exposure D in ASCE 7-88.
