Section 535-X-13-.07 - Minimum Anchoring Standards

(1) No anchors shall be used for anchoring a manufactured home or building to the ground unless the anchor has been tested by a third party testing agency to the required holding power of the anchors. All anchors tested must then have the approval of the Commission. All ground anchors must be installed in the soil classification in which the anchor has been approved. It is the responsibility of the installer to ascertain the soil class and to make sure the anchor is installed in the correct soil. All shear wall locations must have an anchor and support pier installed. Manufactured required longitudinal ties must be installed.

(2) All manufactured homes and buildings shall have anchors spaced as evenly as practical with the piers.

(3) The required number of anchors per each side of each manufactured home and building are shown below:

WIND ZONE II HURRICANE ZONE
*Length of Mobile Home (ft)	**No. of Vertical Ties	No. of Diagonal Ties
0-40	5	5
41 - 60	7	7
61 - 90	9	9

WIND ZONE I NON-HURRICANE ZONE
* * * *No. of Vertical Ties	***No. of Diagonal Ties
0	4
0	6
0	8

*Length of mobile home (as used in this table) means length excluding draw bar.

**The federal manufactured home construction and safety standards require all manufactured homes designed to be located in wind zones II and III to have a vertical tie installed at each diagonal tie location.

***If pier height is over 24", an additional diagonal tie must be added for every additional 12" or a portion thereof.

****Manufactured homes that do not have a HUD label must have three (3) vertical ties per side in zone 1.

(4) Manufactured homes (with HUD labels) and manufactured buildings are not required to have vertical ties in wind zone 1.

(5) All multi section homes shall be lagged and sealed together in accordance with the home manufacturer's instructions.

(6) A zone 1 home cannot be installed in zone 2.

(7) An optional anchoring system that has been approved by the Commission in accordance with 535-X-13-.09 may be used if its use does not conflict with 535-X-13-.06(11).

(8) These minimum anchoring standards are based on the premise that all manufacturers doing business in Alabama have built their homes in compliance with the federal manufactured home construction and safety standards.
