Manufactured Home Foundation Inspections

All foundation systems, new and existing, must meet the guidelines published in the Permanent Foundation Guide for Manufactured Housing (HUD-7584), dated September 1996.  A certification attesting to compliance with this handbook must be obtained from a licensed professional engineer.

It means that the foundation must meet the criteria as set forth in HUD manual Permanent Foundations Guide for Manufactured Housing, September 1996. This manual requires a site specific design for every manufactured home. Dead loads, snow loads, wind loads and seismic loads must all be taken into account. There must be a perimeter, frost line protected strip foundation as well as frost line protected piers under the chassis.

The stacked blocks that the unit actually sits on must not only be mortared, they must be attached with rebar to the footing and bolted and/or welded to the chassis frame, unless there is an alternate, site specific engineered design (which Hayman can provide).  The design must include protection against horizontal shearing forces and uplifting forces. This can require additional strapping between the stacked blocks. Finally, it means that this design must be stamped by a licensed professional engineer verifying that HUD requirements are met.

Pacific Crest Inspections and Hayman Residential Engineering  provides these inspections and reports meeting the FHA and HUD requirements.  Reports are ready in 3-5 days after inspection.

Some of the items that are inspected and verified are:
Site layout, drainage and flood-prone area identification.

Building permit and inspection record.
Foundation size and tie down placement.
Applicable loads on the foundations.
