Legislative Progress
Key Points
- Expands the federal definition of “manufactured home” to include homes built with or without a permanent chassis (the built-in frame).
- Requires the Housing Department to write updated national construction and safety standards for manufactured homes built without a permanent chassis, including special labels and paperwork so they’re clearly identified.
- Pushes states to treat these no-chassis manufactured homes the same as other manufactured homes for things like financing, title, insurance, taxes, transport, and installation.
- If a state doesn’t certify on time that it treats these homes equally, the state must block new no-chassis manufactured homes from being made, installed, or sold there.
- Directs the Housing Department to publish a public list of states that are up to date, and to provide model guidance to help states file the required certifications.
