California eases factory-built housing rules as states move ahead of Congress
California Gov. Gavin Newsom signed laws that ease local rules for factory-built housing, as industry leaders say state action matters more than federal policy.
Key facts
- California Gov. Gavin Newsom signed laws that limit local building standards above state rules for qualifying factory-built projects and change inspection and fee procedures.
- Tom Hardiman, who heads both the Modular Home Builders Association and the Modular Building Institute, said state and local rules have had more effect on projects than federal policy.
- The 21st Century ROAD to Housing Act directs federal agencies to study financing and regulatory barriers and includes changes for manufactured housing.
- Connecticut lawmakers did not pass added safety-review rules for some prefabricated affordable projects; the bill's sponsors started a working group that may recommend changes before the 2027 legislative session.
- Hardiman said seven states have adopted ICC/MBI 1200 standards covering factory inspections and quality control.
