Palm Beach County has 39 incorporated municipalities, most of which manage their own building permits and zoning. The county building department primarily serves unincorporated areas and specific municipalities that contract for services. Projects in unincorporated areas are subject to additional review for the Everglades Protection Area and various coastal high-hazard zones.
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.
