Regulating exterior cladding materials.

Senate Bill 5571 limits the ability of cities, code cities, and counties in Washington State to regulate exterior cladding materials on buildings. It prohibits these local governments from requiring or excluding specific exterior cladding materials if those materials already comply with the state building code. Exterior cladding refers to nonload-bearing materials attached to the outside of a building. This limitation does not apply to homeowners' associations, historic districts, or areas subject to specific architectural themes or wildfire protection codes. Local governments can still adopt building codes that require fire-resistant siding materials for wildfire protection.
