The bill addresses the housing crisis in Washington State by simplifying the permitting process for the construction of kit homes. It amends RCW 19.27.015 to include a definition of "kit homes," which are prefabricated structures designed and constructed in factories to meet specific life, health, and safety standards. The bill also clarifies that these homes must be inspected either by the Department of Labor and Industries for in-state factories or by an equivalent authority for out-of-state factories. Additionally, the bill redefines certain terms related to building permits and introduces a new category for multifamily residential buildings.

Furthermore, the bill establishes a new section that exempts kit homes under 800 square feet from the standard permitting requirements, provided they are located on private property or within a planned unit development on public property. However, these homes must still comply with local fire safety regulations. This legislative change aims to facilitate the construction of affordable housing options in response to the ongoing housing crisis in the state.
