There are many additional questions that need to be asked in order to give a proper answer to this question; in any case, FHA mortgage loans require all manufactured housing to be permanently affixed to an approved foundation. The FHA/HUD official site does have this to say about tie-downs: “ …

Use of Tiedowns The number of diagonal tie downs range from three to five per side in less storm danger areas. In coastal areas, four to seven per side are used to serve the greater need. For single-wide homes, vertical ties (on the roof area) required are two to four, depending on the length of the home.

A diagonal or frame tie-down is needed to compensate for both lateral and uplift forces. Singlewide manufactured homes need both types of tie-downs. Doublewide homes only need the diagonal ties.

Tie-downs are systems of heavy-duty straps and anchors designed to stabilize manufactured homes (also known as mobile homes) during high winds. Failure to properly install and maintain tie-downs results in reduced capacity to resist sliding and overturning.

The base cost of installing tie-downs on a mobile home often hovers around $2000. Numerous factors can cause that number to go up including the current status of your roof. Your plumbing may also have to be reconfigured in order to accommodate the tie-downs. Installing tie-downs on a mobile home is a necessary expense.

Keep Your Mobile Home in Good Repair

1. Make sure your address number is clearly marked on your mobile home.
2. Check and secure all of your mobile home’s tie-downs.
3. Secure any loose roofing and siding.
4. Trim dead or broken branches from trees.
5. Purchase these materials to secure your mobile home:

70-mph
The manufactured home producer designs the home to resist the wind load, which is measured in pounds per square foot. Wind Zone I equates to a 70-mph fastest-mile wind speed. Wind Zone II equates to a 100-mph fastest-mile wind speed. Wind Zone III equates to a 110-mph fastest-mile wind speed.

To level a single-wide mobile home, expect to pay between $450 to $600, while leveling a double-wide mobile home can cost up to $900. Expect to pay $1,000+ for leveling wider mobile homes.

Anchoring straps connect to the steel frame chassis rails to keep the home wind-resistant. These anchoring straps are simply called frame anchors and you can find them used in both new single wide and double wide homes.

by Nick Gromicko and Kenton Shepard. Tie-downs are systems of heavy-duty straps and anchors designed to stabilize manufactured homes (also known as mobile homes) during high winds. Failure to properly install and maintain tie-downs results in reduced capacity to resist sliding and overturning.

How Is The Anchoring System Installed? Anchors are driven into the ground to hold your home down against wind forces. They go into the ground first and then steel straps are attached. The straps connect the anchors to a main I-beam on your home’s steel frame.

For instance, additional anchors and straps may be required along your marriage line wall if you have a double wide or triple wide home. If your home comes with a porch, some of the porch’s posts will also be tied down. And those are the basics of how a manufactured home is tied down to protect the home against wind forces for safety.
