The number of tie-downs required is dependent on two criteria:

1) The Wind Zone where the home is located. To determine which zone your home is designed to be located in, look on the home’s data plate. Here’s a link to our blog about how to find and interpret the data plate:

“How do I find out how old a mobile home is and who manufactured it?”

   To make sure that your home is located in the wind zone that it was designed for, check our blog with a wind zone map at:

“Where are wind zone 2 and wind zone 3 for mobile homes located?”

   If your home is a “D-sticker,” meaning that it was designed to be installed within 1500 feet of the coastline in Wind Zone 3, there are additional installation requirements in Section 15C-1.01031. To learn more about D-sticker homes, go to our blog at:

“What is a D-sticker mobile home?”

  1. 2)The year the home was built. HUD tightened the spacing requirements in the mid-1990s, following the devastation caused by Hurricane Andrew in South Florida, where 97% of all manufactured homes in Homestead were destroyed. In our area, located in Wind Zone II, homes manufactured after the original HUD standards went into effect in July, 1976 and before the upgraded standards enforced beginning in July, 1994, had tie-downs spaced approximately eight feet apart on average. After 1994, tie-downs are placed approximately five feet apart. Additional stabilization bracing is also now required on double-wides. Florida Administrative Code 15C-1, upgraded in 1999, added further standards for wind-resistant mobile home installation. More recently, HUD standardized installation guidelines nationwide in 2009.
       If you are financing an older mobile home purchase, and the financial institution requests a foundation inspection as a requirement for the loan, it is because they want to verify that the home meets the newer tie-down standards. The inspection must be done by a licensed engineer (not a home inspector).

   The installation of a mobile home, including the tie-downs, is required by Florida law to be done by a professional installer licensed by the Florida Department of Highway Safety and Motor Vehicles, with a final inspection by the local building department. Here are some of the defects we typically find in an inspection of a mobile home foundation:

  1. Corroded and loose anchor straps.

  2. Anchor straps that have been cut or removed.

  3. Anchor straps installed at more or less than the specified angle.

  4. Tilting piers, no longer in direct contract with steel frame.

  5. Site-built additions (including porches) that bear on the structure of the mobile home.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
