The Department of Housing and Urban Development (HUD) sets strict standards for the design, construction, and installation of manufactured homes to ensure quality, durability, safety, and affordability. The foundation certification ensures that the manufactured is permanently tied down, will not float off the piers or foundation, and the drainage of the home will not flood the crawlspace or basement. HUD prohibits selling, leasing, or offering for sale or lease, homes that do not meet the standards. Civil and criminal penalties may be sought for violations. You can read more about this here
This is often referred to as a Foundation Inspection, Permanent Foundation Certification, or Engineering Certification. This inspection is required by most mortgage lenders and in some cases insurance providers if you are purchasing a manufactured home. This inspection verifies that the foundation of the manufactured home meets HUD requirements. This report will be prepared by a Licensed Professional Engineer.
This inspection is required in some cases by mortgage lenders to verify that any structures (steps, decks, screen porches, etc.) that may have been added to the manufactured home meet the HUD requirements. This inspection may also include structures that are not in contact with the home but are in close proximity to the home. This report will be prepared by a Licensed Professional Engineer.
