Bay County Building Division handles permits for all unincorporated areas and several smaller municipalities. Incorporated cities like Panama City, Panama City Beach, and Lynn Haven maintain their own independent building departments and permitting portals. All coastal properties are subject to strict Florida Department of Environmental Protection (FDEP) coastal construction control line regulations.
How this fits with the state
The state authority here is Florida DBPR - Construction Industry Licensing Board. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
