Housing Supply Expansion Act of 2025

Key Points

• This bill changes the legal definition of a manufactured home. Currently, these homes must be built on a permanent metal frame with wheels. This new rule would allow homes built in factories to be counted as manufactured homes even if they do not have that permanent frame.
• The goal is to make it easier and cheaper to build more houses. By removing the requirement for a heavy metal frame, builders can create factory-made homes that look more like traditional houses but cost less to produce and move.
• States would have one to two years to update their own laws. They must prove to the federal government that they treat these new types of homes the same as older manufactured homes when it comes to getting a loan, buying insurance, and paying taxes.
• If a state does not update its rules, it will be banned from selling or installing these new types of factory-built homes. This is meant to make sure the rules are the same across the country so builders and buyers know what to expect.
• The Department of Housing and Urban Development will provide guides to help states follow the new rules. They will also work with other federal agencies to make sure everyone is using the same definition for these houses.
