HUD/FHA Manufactured Home Permanent Foundation Certification

Mortgages are available for the purchase of new or existing manufactured homes. Most mortgages written by a lender are almost certain to be insured by the Federal Housing Administration (FHA), a division of the U.S. Department of Housing and Urban Development (HUD).

As a condition of providing insurance, the FHA requires that the foundation for new homes be designed by, and the design sealed by a licensed Professional Engineer. The design must comply with FHA guidelines. For existing homes, a Professional Engineer is required to certify that the foundation meets the FHA requirements.

A permanent foundation is one that is “constructed of durable materials (concrete, mortared masonry, treated wood) and be site built. It shall have attachment points to anchor and stabilize the manufactured home to transfer all loads to underlying soil or rock. The permanent foundations shall be structurally developed in accordance with this document or be structurally designed by a licensed professional engineer.” Although the design must comply with the manufacturer’s instructions, doing so does not guaranty that it complies with the HUD Guide.

The design must provide vertical stability.

There are two methods to prepare acceptable design solutions. The first is to offer an engineered solution using the Guide criteria. The second is to use the appendices in the guide and the worksheets offered to select and document a design of an approved type.
