Spokane County Building and Planning handles permits for all unincorporated areas, while incorporated cities like Spokane, Spokane Valley, and Cheney maintain their own independent building departments and permit portals. Development in unincorporated areas is subject to specific critical area ordinances, including flood hazard zones and wildland-urban interface fire requirements.
How this fits with the state
The state authority here is Washington Department of Labor & Industries. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
