Manufactured Home Foundation Certification
Engineer certification that a manufactured home's foundation meets HUD permanent foundation guidance, often required for FHA and VA loans.
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.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- FHA, VA or conventional loan on a manufactured home
- Lender requests engineer foundation certification
- Relocating or re-setting a manufactured home
- Prior certification missing or outdated
Frequently asked questions
How much does manufactured Home Foundation Certification cost?
Across the US, manufactured Home Foundation Certification usually costs $300 to $1,000 per inspection. Estimate. No authoritative national price survey was found; local quotes vary widely, and homes needing tie-down or pier upgrades cost more.
How long does manufactured Home Foundation Certification take?
Plan on Inspection within 1 to 2 weeks; letter in days from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for manufactured Home Foundation Certification?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
