Boone County Resource Management handles building permits for all unincorporated areas of the county. Incorporated municipalities, such as Columbia, Ashland, and Centralia, maintain their own independent building departments and permitting processes. Development in unincorporated areas is subject to specific floodplain management regulations and stormwater control requirements.
Boone County enforces specific stormwater management and erosion control regulations for all land disturbance activities exceeding one acre.
How this fits with the state
The state authority here is Missouri local building departments; state trade boards where applicable. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
