Many lenders require a foundation certification when purchasing a manufactured home, and attached porches, decks, or steps can create a problem.
Manufactured homes are not designed to carry additional structural loads from site-built additions. Porches, decks, and steps should be independently supported and free-standing so they do not transfer loads to the home.
In this example, the deck was attached directly to the manufactured home, altering the original engineered foundation conditions and preventing certification until properly addressed.
