Bill > SB5552

This bill addresses the growing issue of housing affordability by creating a new category of building codes specifically for kit homes, which are small, prefabricated residential structures of 800 square feet or less that are assembled on-site. The bill modifies the existing state building code definitions in RCW 19.27.015 to formally define "kit homes" and instructs the state building code council to develop specific building code rules for these structures by December 31, 2025. The legislature's motivation is to provide a more affordable housing option for homebuyers with modest means by establishing a specialized regulatory framework that recognizes the unique characteristics of kit homes. The bill allows the state building code council flexibility to update these codes as needed, potentially making small home construction easier and more accessible. By creating this new building code category, the legislation aims to help address housing affordability challenges by reducing barriers to constructing compact, cost-effective residential structures.
