AI Summary
This bill aims to update regulations for factory-built housing and commercial structures by adopting national consensus standards, specifically those published by the International Code Council, Inc., for off-site construction, inspections, and regulatory compliance. It clarifies that "factory built housing" includes tiny houses and defines "qualified inspection agency" as a non-governmental entity approved by the department to conduct inspections, emphasizing their objectivity and independence. The bill also introduces an exemption from department approval for prefabricated enclosures for energy storage and electrical equipment owned by electric utilities, provided access is limited to qualified personnel for maintenance. Furthermore, it allows the department to delegate inspection duties to local enforcement agencies or qualified inspection agencies and mandates that rules adopted by the department consider national consensus standards and existing building codes like the international building, plumbing, and mechanical codes, as well as the national electrical code.
