Pasco County handles permitting for all unincorporated areas and several smaller municipalities that contract for services. Larger incorporated cities like New Port Richey and Dade City maintain their own building departments and permit portals. The county enforces specific coastal high-hazard area regulations and flood zone requirements for properties located within the Gulf of Mexico coastal 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.
