Our national organization, the Manufactured Housing Institute (MHI), issued the following notice yesterday afternoon:

Starting September 17, 2025, the manufactured housing industry will implement a safety enhancement for homes installed in Wind Zone I.  This change is being made to align with the timing of upcoming updates to the HUD Code and will result in alternative foundation designs exceeding HUD Code requirements by including specific uplift protection.



This change reflects the industry’s ongoing commitment to improving the safety and resilience of manufactured homes. While homes built to the HUD Code have consistently demonstrated strong performance in severe weather, this new uplift protection measure adds an additional layer of security for homeowners in Wind Zone I areas.



MHI commends the industry for coming together to recognize that additional vertical anchorage is a meaningful enhancement to storm safety. The manufactured housing industry has a long-standing track record of coming together to improve the performance, efficiency and resilience of our homes, including with respect to severe weather.



Homes built to the HUD Code have proven their improved durability in storms, and the industry continues to analyze performance data and implement innovations that further improve safety and reliability. In keeping with this tradition of proactive improvement, the industry has come together to enhance protections against uplift in Wind Zone I installations. This underscores the industry's dedication to continuous improvement and homeowner safety.

This morning, a letter was forwarded to the Association issued by your three Service/Supplier companies [Minute Man, Oliver Technologies, and Tie Down), which provides further clarification on moving forward with the implementation of this requirement. Installers and inspectors should refer to updated installation instructions provided by the anchor system manufacturers to ensure full compliance with the revised standards by November 3, 2025. (More details below.)

To Whom it May Concern

Following the recommendation of the Alabama Manufactured Housing Installation Task Force, along with a growing consensus among industry professionals, vertical anchorage for uplift resistance is recognized as a safety enhancement to any home installation.

Effective September 17, 2025, aligning with the updates to the HUD Code and supported by Industry professionals, alternative foundation designs will now exceed HUD Code requirements and include specific uplift protection for all homes being placed in Wind Zone I.

To support a smooth transition and allow distributors and installers to familiarize themselves with this change and align inventories of product, we will allow a grace period through November 3, 2025. During this time, both the prior and updated instructions will be accepted.

Installers and inspectors should refer to the updated installation instructions provided by the anchor system manufacturers to ensure full compliance with the revised standards by November 3, 2025.

Contact your local supplier for updated manufacturer’s installation instruction updates or questions regarding this change.
