The Tie Down Law for Manufactured Homes in Florida


Mobile homes manufactured in a factory and towed to their ultimate destination are lightweight, square in shape and set on raised piers. This creates a need for them to be anchored securely to the ground. Manufacturers usually specify the tie down requirements for each model in the home's manual. Florida weather often includes extremely high winds. Chapter 15C-1 of the Florida Administrative Code lays out the minimum requirements, but mobile home owners should check with their local counties before commencing with the tie-down procedures.


  • Homes manufactured prior to July 13, 1994, must be anchored using Type I anchors, tested at a working load of 3,150 lb. with an ultimate load of 4,725 lb. Homes manufactured after that date must be anchored with Type II anchors, tested with a holding power of 4,000 lb. with an ultimate load of 6,000 lb. Anchors can be purchased at mobile-home supply stores.

Frame Ties

  • Frame ties on both new and used mobile homes in Florida are required to have an approved strap connected to an I-beam clamp at the top of the I-beam. Frame ties must be installed following the manufacturer's directions.

Diagonal Tie-Downs

  • Diagonal tie-downs must not be spaced further apart than 5 feet 4 inches on center; anchors must be placed within 2 feet of each end. If the sidewall strap is further apart, the diagonal tie-downs must be tied individually.

Longitudinal Tie-Downs

  • All new mobile homes installed must have longitudinal tie-downs designed to resist wind loads affecting each end of the home. At least four anchors and straps are required at each end or section of the mobile home.

Centerline Ties

  • Centerline ties must be used for all multiple-section homes, such as double- and triple-wides. A centerline tie must be attached within 2 feet of each end of each section. If the manufacturer did not install a bracket for this purpose, the installer must add one. Centerline tie connections must be able to swivel, at the point of connection to the home, and should be attached using grade #5 bolts that are at least 1/2 inch in diameter.

Roof Ties

  • Roof ties are required for all mobile homes manufactured prior to June 15, 1976, except those officially designated "hurricane resistant." All homes manufactured before July 13, 1994, require roof ties.
