This bill introduces new sections to chapters 64.38, 64.34, and 64.90 of the Revised Code of Washington, aimed at preventing unreasonable restrictions on wildfire home hardening practices within common interest communities. It stipulates that governing documents cannot prohibit the installation, use, or maintenance of fire-hardened building materials, provided these materials meet applicable health and safety standards set by state and local authorities. Additionally, while reasonable rules regarding the design and appearance of these materials can be established, such rules must not make the use of the materials infeasible or increase their cost by more than 10 percent compared to other fire-hardened options.

The bill also clarifies that property owners do not have the right to place fire-hardened materials on property owned by others, leased property without permission, or common areas of the association. It retroactively applies to existing governing documents, rendering any inconsistent provisions void and unenforceable. The definitions of "fire-hardened building materials," as well as references to the International Wildland Urban Interface Code and the National Fire Protection Association standards, are included to ensure clarity. The provisions of this bill are set to expire on January 1, 2028.
