The bill amends existing laws to facilitate the siting of kit homes, which are defined as prefabricated structures intended for residential use, measuring 800 square feet or smaller. It allows municipalities and counties to permit these homes in areas designated for single-family or other residential uses, as well as in limited development spaces for emergency housing. The legislation mandates that local governments adopt ordinances or actions to inspect these kit homes at least every five years to ensure they meet necessary life, health, and safety standards.

Specifically, the bill modifies RCW 35A.63.100 to eliminate minimum gross floor area requirements for single-family detached dwellings and introduces provisions for the use of kit homes as emergency housing. Additionally, new sections are added to chapters 35.63 and 36.70 RCW, outlining the authority of cities and counties to site kit homes and the requirements for their inspection. This legislative change aims to address housing shortages by providing a flexible solution for emergency housing needs.
