More siding choices for Washington homeowners

Beginning July 27, 2025, Washington cities, code cities, and counties generally cannot require or ban siding materials that meet the state building code. This gives owners and builders more choice. The law covers exterior materials attached to buildings that do not support the building's weight. Exceptions cover homeowners’ associations, plat communities, locally designated historic districts, districts on the National Register of Historic Places, and local, state, or national historic landmarks. Exceptions also cover areas under locally adopted International Wildland Urban Interface Code rules. Cities and towns with legally required old-world Bavarian building styles are exempt; counties have an exception for structures adjacent to those municipalities. Local governments may still require fire-resistant siding for wildfire protection.
