Can a mobile home permanent foundation be concrete blocks on pads and screw-in anchors?

Friday, June 17, 2022

HUD requires that a "permanent foundation" for a manufactured/mobile home must be built of durable materials at the homesite. It also has specific, detailed requirements for the foundation construction. And Florida has more stringent standards, known as the “Florida Override,” that must be met for installations within the state. "Crawl space” type foundations utilizing stacked concrete blocks on pads and tie-down straps secured with screw-in soil anchors are acceptable as a permanent foundation, but only if installed per HUD and State of Florida standards, or a design by a licensed professional engineer. 

    Most mortgage lenders and insurance companies require certification that the installation meets permanent foundation standards by a licensed professional engineer, often called a “foundation cert," before lending or issuing homeowners insurance. These standards were updated by the State of Florida in 1999 and HUD in 2009, so older mobile homes that have not had their foundation upgraded likely will not meet the current standards.
