For the public safety and welfare of all mobile home occupants, it is hereby determined, deemed necessary on and after November 1, 1976, all owners and occupants, individually and jointly, of mobile homes are required to provide tie-downs, skirting, and approved foundation piers for the mobile home owned and/or occupied by them.
(a) Steel auger anchors, cast in place concrete “deadman” eyelets embedded in concrete foundations, or arrowhead augers are permitted, subject to approval of the City Building Inspector. Screw augers shall be sunk to a depth of at least four feet.
(b) Each tie-down shall have a minimum tensile strength of 4,800 pounds.
(c) Woven wire cable of galvanized steel or stainless steel three-eighths inch in diameter or larger, or one-fourth inch aircraft cable, or equivalent galvanized strap, with turnbuckles, or the equivalent, shall be attached as tie-downs.
(d) All mobile homes shall have at least two over-the-top tie-downs placed as close to each end of the mobile home as practicable, and one tie-down shall be located as close to the center of the mobile home as possible. The distance between all such adjacent tie-downs shall be as nearly equal as practicable.
(e) For mobile homes, 32 feet to 50 feet in length, three frame tie-downs shall be placed on each side, or three over-the-top tie-downs shall be used; more than 50 feet in length and not more than 70 feet in length, four frame tie-downs shall be placed on each side, or four over-the-top tie-downs shall be used; more than 70 feet in length, five frame tie-downs shall be placed on each side, or five over-the-top tie downs shall be used.
(f) Roof protectors shall be used with all tie-downs securing mobile homes not equipped with tie-downs by the manufacturer. Roof protectors shall be made of rust-resistant material and placed at stud and rafter locations on a mobile home.
(g) Over-the-top tie-downs may be attached to the same ground anchor as frame tie-downs.
(h) Every mobile home shall be skirted with noncombustible material that is approved by the City Building Inspector.
(i) Foundations for piers shall be installed directly under the main frame or chassis of the mobile home. All grass and organic material shall be removed and the pier foundation placed on stable soil. The piers shall not be farther apart than ten feet on centers, and the main frame of the mobile home shall not extend farther than one foot beyond the centerline of the end of the piers. Each pier foundation shall consist of two concrete blocks, and each such block shall be eight inches wide, eight inches high and 16 inches long.
(j) Piers shall be constructed of either open cell or solid concrete blocks, each which shall be eight inches wide, eight inches high and 16 inches long, with open cells vertical or in combination with solid concrete blocks which are two inches thick, eight inches high and 16 inches long placed above the foundation block. A wood plate which is at least one inch in actual thickness, eight inches high and 16 inches long shall be placed on top of the pier, with weather proof wood shims, when needed, fitted and driven tightly between the wood plate and the main frame. Such shims shall not occupy more than one inch of vertical space. Piers shall be installed perpendicular to the i-beam. All piers over 30 inches in height, measured from the top of the foundation block to the i-beam, shall be double tiered with blocks interlocked and capped with a solid concrete block, which shall be four inches high, 16 inches wide and 16 inches long, cushioned with wood blocking as required. Piers shall not exceed 48 inches in height, unless designed by a registered professional engineer or architect.
