The bill aims to adopt national standards for factory-built housing and commercial structures in Washington State by amending several sections of the Revised Code of Washington (RCW). Key definitions are established, including "factory built housing," "commercial structure," and "qualified inspection agency," with the latter now requiring approval by the department. The bill stipulates that no factory-built housing or commercial structure can be installed without the department's approval and insignia, ensuring compliance with local laws and regulations. Notably, the bill introduces a provision that exempts prefabricated enclosures for energy storage systems or electrical equipment from department approval, provided they are under the exclusive control of an electric utility and accessed only by qualified service personnel.

Additionally, the bill grants the department the authority to delegate inspection duties to local enforcement agencies and outlines the criteria for qualified inspection agencies, emphasizing their independence and objectivity. The department is tasked with adopting rules that align with national consensus standards from the International Code Council, ensuring that factory-built structures are safe and structurally sound. The bill also includes provisions for fee schedules to cover administrative costs and allows the governor to waive fees during declared emergencies to facilitate government operations and protect public safety.
