Suppliers and builders within manufactured housing are now making industry professionals aware of a new vertical anchoring system for factory-built home foundations, aiming to strengthen stability and safety in high-wind areas, though the change is not currently mandatory under federal rules.
The recommendation, introduced in November, encourages installers using a “pan-system” or alternative foundation systems in Wind Zone I to include vertical anchors in new home installations. Companies, including Minute Man Anchors, Oliver Technologies Inc., and Tie Down Engineering, collaborated in the development of the updated guidelines for the approach to improve performance against wind uplift and shifting.
Under the guidance, installers are urged to follow the manufacturer’s instructions, which now include vertical anchoring as an optional enhancement. The approach goes beyond federal requirements set by the U.S. Department of Housing and Urban Development installation and safety standards.
Standard installation practices for homes using traditional block-and-tie-down systems remain unchanged. For pre-owned homes, installers may continue to rely on existing manufacturer or state standards without modification.
Industry experts say the recommendation reflects a growing effort within manufactured housing to promote stronger, more resilient installation practices, particularly in regions that experience periodic high winds.
While the new vertical anchoring guidance is voluntary, many installers and foundation manufacturers are expected to adopt the measure as a best practice in 2026 and beyond.
