FAQs about Mobile Home Wind Zones

1. What wind zone is my mobile home?

To find out what wind zone your mobile home is located in you will have to call your local building department or fire department. 

This information can usually be found on the official paperwork filed with your local government when your home was built.

2. What are the requirements for mobile homes in high-risk zones?

Homes located in heavy wind areas are required to meet much higher standards than those in lower-risk zones. 

Not only must they be anchored but because of their extreme vulnerability, mobile homes in these high wind areas must also follow specific guidelines for construction depending on where they were manufactured and who manufactured them. 

For example, if a mobile home was manufactured by a company that holds an AISC (American Institute of Steel Construction) certificate then it will be required to meet certain criteria that may not apply to homes manufactured by companies that do not hold this distinction.

Please note: If you live in a mobile home and plan on selling it, property appraisers will most likely require proof of wind zone information as part of the sale process. 

This is why you should have this information on hand before making an offer so you can avoid having your sale delayed unnecessarily.

3.How does wind affect mobile homes?

It is common knowledge that mobile homes are especially susceptible to damage in high winds because they are not anchored in the ground. 

They are built on top of a series of steel beams called skirting which allows them to be situated in areas where there is no available land for conventional foundations. 

If you live in an area where high winds are a concern, you should make sure that your home is securely anchored to at least one of these beams. Checking with a mobile home repairman can help with this process.
