During a recent inspection on a manufactured home, I took the opportunity to document two very common conditions I see during foundation certifications: This situation comes up all the time—especially with homes that are 10–30+ years old. The big question homeowners ask is: “If my deck or stairs are old or not built to today’s code, will that ruin my loan or foundation letter?” The Short Answer Not automatically.But it depends on how the structure relates to the manufactured home and how it’s addressed. What a Manufactured Home Foundation Letter Actually Covers A manufactured home foundation letter (HUD Permanent Foundation Certification) is focused on one thing: 👉 Whether the manufactured home itself is properly supported, anchored, and performing as a permanent foundation system per HUD requirements.

The purpose of the foundation letter is not to certify every structure on the property. The manufactured home’s primary structural support and permanent foundation system are not negatively affected by accessory structures such as decks, stairs, or porches.

Problems arise when: A properly written engineering letter: This approach protects: How I Handle This in My Foundation Letters When I encounter aging or sub-standard stairs or decks, I typically: This keeps the letter: And most importantly—it keeps loans moving. Any visible safety-related conditions observed during the site visit are communicated to the owner for maintenance or repair consideration and are documented separately from the manufactured home foundation certification scope.
