Does my mobile home meet wind zone 2 standards?

Data Plate Will Tell You The Wind Zone Rating
Look at manufacturer’s data plate to determine which wind zone standard your home was constructed to meet. It’s a paper sticker that is typically located on the wall of the master bedroom closet, inside a cabinet door in the kitchen, or near the electric panel. Here’s a photo of one below, with a red box around the wind zone part of the sticker.
Shown below is an enlargement of that area. The wind zones are noted in Roman numerals, so an X in the box next to it indicates that this home is in “Zone II.” There is also a map showing the parts of the states that each wind zone covers, and a note that states that Wind Zone II and III homes should not be located within 1500 feet of the coastline unless the home and its anchoring and foundation system have been designed for the increased requires specified for Exposure D in ANSI/ASCE 7-88. Homes designed for Exposure D, also called “D-sticker” homes, have additional storm-resistant construction features.
If your data plate has been removed or you can’t find, there is still hope: if you can locate either the HUD certification number or the serial number, then you can obtain the original data plate info from the Institute for Business Technology and Safety, a HUD contractor that maintains a database back to 1976 of HUD-code manufactured homes. There’s a fee of $100 for a replacement data plate by email. See our blog post What is a "HUD data plate/performance certificate" for a mobile/manufactured home? for details.
The HUD certification number is etched into a 2” by 4” metal plate (called the “HUD tag”) riveted to the exterior wall of each section of a mobile on the long side at a corner near the bottom. There’s a picture of one below. It starts off life bright red, but will likely be faded when you find it. If even the HUD tag is gone, crawl under the home with a flashlight and look for the serial number on the forward cross-member of the steel I-beam frame. It is required by HUD to stamped into the metal by the manufacturer in letters a minimum of 3/8” high.
If your mobile home was manufactured before June 15, 1976, when HUD-Code regulations went into effect, there will not be a HUD data plate in the home and HUD will not certify pre-1976 mobile homes for a wind zone, no matter how storm-resistant the construction.
