What the work involves

For FHA-insured and many other mortgages on manufactured homes, HUD requires a foundation certification from a licensed professional engineer or registered architect stating the foundation complies with the Permanent Foundations Guide for Manufactured Housing. The engineer inspects piers, footings, anchors and tie-downs, notes deficiencies and issues a stamped certification once compliant.
