Effective 8/10/2022, state bill HB22-1242 regulates the sale and manufacturing of movable tiny homes. The bill requires the development of rules to ensure consumer safety, registration of manufactured home installers, and development of uniform standards for foundation systems and installation.

Effective 7/1/2023, the Division of Housing’s Building Codes and Standards (BCS) is regulating the manufacture, sale, and installation of tiny homes, following these established rules.

The Division of Housing must conduct a full design and plan review and inspection of the construction of factory-built structures to the extent the design and construction relates to work performed offsite or work that is completed onsite using components shipped with the factory-built structure as reflected in the approved plans for the factory-built structure. A local government may not duplicate efforts to review or approve the construction of a factory-built structure that is under review or approved by the Division of Housing nor may it charge building permit fees to cover the cost of plan reviews or inspections performed by the Division of Housing.
