15C-1.0104 Installation Standards for Anchors and Tie-downs.These specifications are standards set by the Department of Highway Safety and MotorVehicles for new and used mobile/manufactured homes or park trailers.(1) Anchors:(a) Type I anchor holding power for homes manufactured before July 13, 1994, shall betested to a working load of three thousand one hundred fifty (3,150) pounds, with anultimate load of four thousand seven hundred twenty-five (4,725) pounds.(b) Type II anchor holding power for homes manufactured after July 13, 1994, shall betested to a working load of four thousand (4,000 pounds, with an ultimate load of sixthousand (6,000) pounds.(2) Frame Ties:(a) All frame ties for new and used mobile/manufactured homes must have a factoryfabricated strap connected at the top of the I-beam to an I-beam clamp approved bythe department. Diagonal tie-downs for new and used mobile/manufactured homes,in all wind zones, shall be spaced no farther apart than five feet four inches (5’4”) oncenter with anchors placed within two feet (2’) of each end. Note: Where sidewallstrap separation is greater, they must be tied individually. Each frame tie shall beinstalled to the component manufacturer’s instructions. (Refer to below drawing)StrapBeam Clamp DetailPivoting Frame Tie Beam Clamp
(3) (a) Longitudinal Tie-downs. All new and used mobile/manufactured homes, installedsixty (60) days after the effective date of this rule, must have longitudinal tie-downsor other approved longitudinal stabilizing systems designed to resist horizontal windloads in the long direction of the home (i.e. wind load applied to each end of thehome). The longitudinal tie-downs are in addition to the anchoring systems requiredalong the exterior sidewalls and/or marriage walls of the mobile/manufactured home.(b) When anchors and straps are used for stabilizing the home in the longitudinal directionthe strap must connect to a clip welded onto the I-beam or other device connectedmechanically. Unless factory installed, the department must approve the connectiondevice. At least four (4) anchors and straps are required (i.e., 16 per double-widehome) at the end of each section of the mobile/manufactured home.(4) Marriage Wall/Centerline Ridge Beam Column Ties, Shear Wall Ties and Frames Ties:(a) Centerline ties are required for all new and used multiple section homes.(b) Multiple-section homes are to be secured at the centerline with straps to thespecifications in the manufacturer’s manual or at the locations designated on thehome. In addition to centerline ties specified by the manufacturer, a centerline tiemust be attached within two feet (2’) of each end of each section of the mobile/manufactured home. Where necessary, an approved bracket shall be added by theinstaller.(5) Roof Ties:(a) Homes manufactured after June 15, 1976, without over-the-roof ties, but designated“Hurricane Resistant” per for Federal Manufactured Home Construction and SafetyStandards, section 3280.305(c)(2), as hereby incorporated by reference, shall notrequire roof ties. All manufactured homes manufactured after July 13, 1994, shallrequire vertical and frame tie points.
(b) Homes manufactured before July 13, 1994, where factory installed roof ties are notevident and it cannot be determined that the mobile/manufactured home is “HurricaneResistant” without such ties, then the number of roof ties, as required by the tablebelow, shall be installed so as to not contact with the structure, except at adequatelyreinforced areas, where additional load will not damage the structure.1. Single-wide homes less than or equal to sixty feet (60’)–three (3) roof ties.2. Single-wide homes greater than or equal to sixty-one feet (61”)–four (4) roof ties.3. Double-wide homes–roof ties required only if installed by the manufacturer.(c) All new park trailers manufactured after January 2, 1995, shall have at least three(3) factory installed vertical tie points in addition to the required frame ties.(d) End roof ties or vertical ties shall be installed at not more than twenty-four inches(24”) from the end of the structure or at the first stud and truss and attached to thesame anchor as the frame tie. If the frame does not extend to the back end wall, thenthe roof tie shall be within six inches (6”) of the end of the chassis.(e) Intermediate roof ties or vertical ties shall then be located at midway or equallyspaced between the end roof ties, as feasible.(f) Double-wide homes manufactured before July 13, 1994, may not require roof ties,unless such ties are installed or provided by the manufacturer. However, additionsor canopies may require such ties depending on the type of construction. All aresubject to the same frame tie requirements as single-wide homes.(g) Over-the-roof tie-down straps or tie points shall be connected to a ground anchor. Ifa strap has been damaged, cut off or removed, a replacement strap shall be installedor spliced using two (2) listed strap seals affixed to twelve inch (12”) overlap ofstrap with two (2) crimps evenly spaced on the seal.(h) Used homes designed and requiring over-the-roof tie-downs and having a permanenttype structure adequate to provide structural rigidity and stability, meeting the designloads as required by the Standard Building Code, as hereby incorporated by reference,shall not be required to have over-the-roof ties in the area of the addition, but shallrequire one at each end.(6) Center Line Fastening: multiple section homes shall be mechanically fastened everytwenty-four inches (24”) at the bottom, end walls and roof. A minimum thirty (30)gauge, eight inches (8”) wide, galvanized strip shall be centered over the peak andfastened with galvanized roofing nails at two inches (2”) on center at both sides ofcenter line.Specific Authority 320.011,320.824(1),320.8325(2) FS.Law .835(2)FS history-new 1-10-94,amended 10/2/95
(h) The minimum distance between the finished grade under all new and used mobile/manufactured homes and the bottom of the I-beam shall be eighteen inches (18”).Where the grade is sloped, twenty-five (25%) of the lowest member of the mainframe may be set below eighteen inches (18”); however, under no circumstancesmay the bottom of the I-beam be set below twelve inches (12”) from the finishedgrade.(2) Foundations:(a) Concrete pads or foundations shall be a minimum of two thousand five hundred(2,500) pounds per square inch (psi).(b) Plastic pads or foundations shall be tested in the lower fifty percent (50%) of eachsoil class.Pier Spacing TableTABLE AFooterLoadSizeBeaningCapacity16” x 16”18-1/2” x 18-1/2”20” x 20”26” x 26”1000 psf3’4’5’8’1500 psf4’ 6”6’7’2000 psf6’2500 psf7’ 6”3000 psf3500 psfShaded areas are at the maximum eight feet spacingFigure ABlocking (Single Tiered)I-Beam (Frame)Wood Shims or other material approved and listed by the departmentpursuant to rules 15C-1.0105 and 15C-1.0108 (1-1/2” Maximum)Cap - 2” x 8” x 16” Pressure Treated Wood or other material approvedand listed by the departmentCelled Concrete BlockGround LevelFooter or Pier Foundation4” x 16” x 16” Solid (One Piece) or other material approved and listed by thedepartmentSod and Organic Material Removed
