This 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. The legislation allows municipalities and counties to permit the use of kit homes in areas designated for single-family or other residential uses, as well as in limited development spaces for emergency housing. To ensure safety and compliance, the bill mandates that local governments adopt ordinances for inspecting these homes at least every five years to verify they meet 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 necessary inspection processes. This legislative change aims to address housing shortages by providing a flexible and efficient solution for emergency housing needs.
