Every manufactured home is built to a HUD Code wind zone. Mobile homes, which were built before 1976, are not actually built to a wind zone because federal mobile home safety standards weren't in place before 1976.
However, all manufactured homes, which were built after 1976 to HUD Code, are built to specific wind safety standards.
The HUD Code has even gotten revised since 1976! After major storms like Hurricane Andrew, HUD studied different building standards and updated requirements for snow, seismic activity and wind safety to ensure that manufactured homes are built with safety, strength and durability in mind.
The HUD Code wind zones are NOT based on where your home is built, but on where your manufactured home will be placed. The wind zones are designated by the U.S. Department of Housing and Urban Development as seen in the picture below.

The above zones indicate how much wind pressure a home must withstand. The wind zone determines how the home is built and, just as importantly, how the home is anchored to the ground.
Building For Different Wind Zones
For your safety, a home built to wind zone I cannot be placed in zones II or III, but a home built to wind zone III can be placed in lower wind zones.
Most homes that need to be built to wind zone III are located in Florida or Louisiana because of obvious hurricane exposure. If you’re worried about high winds for any reason, asking for your home to be built and installed to wind zone III standards could be a great precaution to take.
Since all manufactured homes are now built and permanently affixed to land according to federal wind regulations, they are a very safe and reliable housing option for families across the country.
Manufacturedhomes.com notes that not one manufactured home built after the 1994 HUD Code changes was destroyed by the hurricanes that hit Florida in 2004. I’d say that’s pretty safe!
How to Find Your Home’s Wind Zone
To find your manufactured home’s wind zone, you can look at the HUD data plate that is posted inside your home. Usually, you can find the data plate inside a kitchen cabinet, bedroom closet or the electrical box. It will tell you not only your home’s wind zone, but also information like your snow load and roof load.
If you can’t find your data plate, you can also look up your serial number on your HUD tag, also called a HUD Certification Label, which is a metal plate attached to your home’s exterior. You can use the serial number on your HUD tag to look up information about your home like the wind zone it was built for.
One way home builders ensure your home is safe for your zone is the materials with which your home is built, but another way is the type of anchoring or foundation your manufactured home has.
