Ala. Admin. Code r. 535-X-13 § 535-X-13-.07
Minimum Anchoring Standards
Operative Text
(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 II 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.
Ala. Admin. Code r. 535-X-13 § 535-X-13-.07 establishes minimum anchoring standards for manufactured homes and buildings in Alabama, specifying that all ground anchors must be third-party tested, Commission-approved, and matched to the correct soil classification. The rule sets out required numbers of vertical and diagonal ties based on the home's length and wind or hurricane zone, with stricter requirements for taller pier heights and homes lacking a HUD label. Multi-section homes must be lagged and sealed per manufacturer instructions, and a home rated for Wind Zone 1 cannot be placed in a Wind Zone 2 location.

Property owners and managers overseeing the installation of manufactured homes in Alabama generally ensure compliance with Ala. Admin. Code r. 535-X-13 § 535-X-13-.07 by verifying that all anchors carry both third-party testing certification and Commission approval before installation begins. Compliant operators confirm the soil classification at the site and select anchors specifically approved for that classification, then space anchors as evenly as practical with the piers and install the correct number of vertical and diagonal ties for the home's length and wind zone. For multi-section homes, lagging and sealing in accordance with the manufacturer's instructions is also part of standard compliant practice.

Tenants living in manufactured homes in Alabama have an interest in knowing that Ala. Admin. Code r. 535-X-13 § 535-X-13-.07 requires installers—not tenants—to bear responsibility for verifying soil classification and using properly tested, Commission-approved anchors suited to the home's wind zone and length. If a tenant has concerns that a home may not have been anchored in accordance with these minimum standards, general enforcement paths include contacting the Alabama Manufactured Housing Commission, which oversees compliance with these rules, or reaching out to a tenant-rights organization for guidance. Documenting the home's installation details and any observable anchoring conditions can be a useful step when exploring available options.
