U.S. Senators Mike Crapo (R-Idaho), Thom Tillis (R-North Carolina), Tim Scott (R-South Carolina), Ruben Gallego (D-Arizona), Katie Britt (R-Alabama), Brian Schatz (D-Hawaii) and Alex Padilla (D-California) have introduced the bipartisan Housing Supply Expansion Act of 2025. The proposed legislation aims to update the federal definition of “manufactured housing” to include modular or prefabricated homes that are built without a permanent chassis.
Supporters say this change would allow for off-chassis manufactured homes, broadening consumer access to more efficient and cost-effective housing designs. The bill is intended to provide greater architectural flexibility, making it easier for these homes to fit into existing neighborhoods.
“We must find new, innovative ways to expand affordable housing venues so more individuals can achieve the American Dream of owning their home,” said Senator Crapo. “It is time to throw out established norms and cut bureaucratic hurdles that stand in the way of innovative designs to increasing affordable housing.”
Senator Tillis added, “I’m proud to support this commonsense legislation that expands housing options for hardworking families in North Carolina and across the country. By modernizing the definition of manufactured homes, we can encourage innovative and affordable designs and help more Americans achieve the dream of homeownership.”
Senator Scott stated, “Manufactured housing plays an important role in helping more Americans access homeownership, but we need to make sure outdated regulations aren’t preventing newer, potentially more innovative models from coming to market. This legislation will remove red tape and lower the costs of building these types of homes, increasing access to affordable housing opportunities for Americans across the country.”
“Manufactured homes are some of the most affordable housing solutions on the market, but outdated laws are preventing newer, safer models from becoming widely available,” said Senator Gallego. “Our bipartisan bill makes a simple update to allow for greater design flexibility and bring down the cost of manufactured homes.”
Senator Schatz commented, “We need to build as many homes as we can to address our national shortage, and we can’t let outdated rules needlessly constrain supply. Our bill will unlock manufactured homes in both urban and rural areas around the country, making manufactured homes and all housing more accessible and affordable.”
“With this small adjustment, our legislation would help increase the production of affordable housing in California during a historic housing crisis,” said Senator Padilla. “Simply modifying the definition of manufactured houses would cost the government nothing and could unlock greater design flexibility while increasing the desperately needed affordable housing supply.”
