Manufactured Home Foundation Certifications in Texas, FHA and VA

What the certification is measured against

Both FHA and VA point at the same technical document: the HUD Permanent Foundations Guide for Manufactured Housing, published as HUD-7584. FHA carries the requirement in Handbook 4000.1, which asks for a certification by a licensed professional engineer or registered architect that the foundation complies with that guide. VA carries an equivalent requirement in its own lender handbook.

This matters because it defines what the engineer is looking at. The certification is not a home inspection and it is not an appraisal. It is an observation of the foundation system against a published federal standard, and the answer is either that it complies or that specific items do not.

What gets looked at on site

The observation is of the foundation system as built, which means somebody has to be under the home with a light. The items below are the recurring ones in Texas, and the last three are the ones that most often come back as deficiencies.

• Footings: type, size, and bearing, and whether they extend below the local frost or design depth.
• Piers: spacing, height, construction, and whether piers over a certain height are reinforced.
• Anchorage and tie-downs: presence, type, condition, and connection to both the frame and the footing.
• Perimeter enclosure: a continuous, permanent enclosure of the crawl space, properly vented and accessible.
• The HUD data plate and certification labels, and the home's serial and HUD label numbers, which have to match the loan file.
• Site drainage away from the foundation, which is a real structural item in Texas clay and not a cosmetic note.
• Evidence that the towing hitch, axles, and wheels have been removed, which is part of what makes the home real property.

Why a Texas engineer, specifically

The certification must be sealed by an engineer licensed in the state where the property sits. A certification from an out of state engineer is not a document a Texas underwriter can accept, and discovering that late is expensive.

Texas also has its own soil problem. Large parts of the state sit on highly expansive clay, and a pier and anchor system that would be unremarkable in a stable soil region behaves differently through a Texas summer. That shows up in the observation as differential movement, and it is worth an engineer who reads it as a soil signal rather than as a construction defect.

When the foundation does not comply

A deficient foundation is a common outcome, particularly on older homes and on homes that were sited before the current guide existed. What comes back in that case is a list of the specific items that do not comply and what would bring each into compliance. Once the corrections are made, the home is re-observed and the certification is issued against what is actually there.

Nobody will tell a loan officer in advance that a certification will be issued. The seal means the engineer observed the foundation and found that it complies. That statement is worth something precisely because it is not available on request.
