Kitsap County Department of Community Development manages permits for all unincorporated areas, while incorporated cities like Bremerton, Poulsbo, and Bainbridge Island maintain their own independent building departments. The county enforces critical area ordinances, including significant wetland, steep slope, and shoreline management overlays that require additional environmental review for development.
Kitsap County enforces a strict Critical Areas Ordinance that mandates specific buffers and mitigation plans for development near wetlands, fish-bearing streams, and geologically hazardous areas.
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.
