Okla. Admin. Code § 765:37-7-4
Current through Vol. 42, No. 7, December 16, 2024
Section 765:37-7-4 - Anchoring for previously occupied manufactured homes(a) Ties shall be as evenly spaced as practicable along the length of the home, and the distance from each end of the home and the diagonal tie nearest that end shall not exceed 2 feet. Ties will be spaced no more than 11 feet apart on a side, allowing adjustment for obstructions (any strap spacing may be exceeded by 10%, so long as the average strap spacing does not exceed 11 feet). The number of ties per side will be calculated by the formula: section-length , divided by the spacing of 11 feet (rounded to next whole number), plus 1 tie. [The result for a 16'x80' (overall length) would be 8 diagonal ties per side.] (b) Over-the-top vertical ties will not be necessary for home 13.5 feet or wider, with 10 feet or less wall height, with I-beams that are 96 inches or more apart, with no evidence that vertical ties have been cut or removed and with diagonal ties installed extending to the nearest I-beam. (c) Where a vertical tie and diagonal tie are located at the same place, both ties may be connected to a single anchor, provided that the anchor used is capable of carrying both loadings. (d) Anchors shall be capable of resisting a minimum total load capacity of 4,725 pounds (2,143 kg) and a working capacity of 3,150 pounds (1,429kg). (e) All anchoring devices shall be installed in accordance with the anchor manufacturer's instructions, including, but not limited to, the use of approved stabilizer plates or 10" diameter x 18" deep poured concrete cylinders to prevent lateral movement of the anchor through the soil. (f) Tie down anchors are not required when the home is installed on a FOUNDATION SYSTEM designed by an architect or registered engineer, which is designed to resist all tributary vertical live and dead loads, as well as lateral loads (wind or seismic), for the local conditions.
