All foundation systems, new and existing, must meet the guidelines published in the Permanent Foundations 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 and included in the insuring file. This procedure does not apply when the current FHA borrower refinances their loan. It is applicable for all re-sales.

HUD Handbook 4145.1, Rev-2, Section 3-4. C. "Criteria for Existing Properties", dated Feb. 1990 states: "The foundation design information in HUD Handbook 4930.3G, Permanent Foundations Guide for Manufactured Housing, Appendices A, B and C, may be used to verify the design of the existing system. Provide a licensed professional engineer's certification to verify compliance with the handbook guidelines and with the requirements set forth in paragraph 3-4.B." Note: HUD Handbook 4930.3G was replaced by as HUD-7584, Permanent Foundation Guide for Manufactured Housing.
