Clark County Community Development manages permits for all unincorporated areas, while incorporated cities like Vancouver, Camas, and Battle Ground operate their own independent building departments. Development in unincorporated areas is subject to specific critical areas ordinances, including flood hazard zones and steep slope regulations that require additional environmental review.
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.
