Hillsborough County Development Services manages permits for all unincorporated areas, while the cities of Tampa, Temple Terrace, and Plant City operate their own independent building and zoning departments. Development within the county is subject to the Hillsborough County Land Development Code, which includes specific requirements for the Urban Service Area and various environmental overlays such as the Wellhead Resource Protection Area.
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.
