   1. (1)

      1. (A) Multisection manufactured homes require only diagonal frame ties and anchoring.
      2. (B) Such ties shall be installed according to the manufacturer's DAPIA-approved anchoring instructions.
      3. (C) In the case of used multisection homes, the anchoring shall be done according to the rules and specifications set forth in this section.
   2. (2) The number and spacing of frame ties and anchors required for multisection manufactured homes shall be based upon the length of the home and shall be the same spacing as that specified for single-section manufactured homes in subdivision (b)(2)(A) of this section.

4. (d) Anchoring — Installation of ground, rock, and concrete anchors.

   1. (1)

      1. (A) All ground anchor systems and each component as used in each ground system (soil, gravel, rock, etc.) shall be capable of withstanding without failure a vertical and diagonal pull of four thousand seven hundred twenty-five pounds (4,725 lbs.) at each tie for single‑headed anchors or nine thousand four hundred fifty pounds (9,450 lbs.) for double‑headed anchors.
