Do I need a permit for addition or structural alteration in Unincorporated Pasco County?

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Unincorporated Pasco County is no exception.

A building permit is required for any addition and for structural alterations such as removing or altering load-bearing walls, changing the footprint, or altering the roof structure. The Florida Building Code only exempts ordinary minor repairs that do not cut into walls or remove load-bearing supports, so structural work is never exempt. Additions usually trigger zoning review and, in flood areas, elevation requirements.

Florida and local notes for Unincorporated Pasco County

Structural work is specifically excluded from the HB 803 $7,500 exemption. Signed and sealed engineered plans are commonly required. Additions often trigger setback, lot-coverage, and floodplain review. Pasco County's own permitting office is the Pasco County Building Construction Services office, reachable on 727-847-8126 at https://www.pascocountyfl.gov/services/building_construction/index.php. Its online permit portal is https://aca-prod.accela.com/pasco/Default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. An addition means a full plan review, so confirm submittal requirements and current review times before you commission drawings. Pasco County's Additions package requires a signed and sealed drainage plan when more than 500 square feet is added or the lot is under an acre. An approved drainage plan on file can be requested by email to PRR@mypasco.net. Residential permits that increase living area trigger county impact fees, which must be paid before the permit or certificate of occupancy is issued. The county offers an impact fee study for $30. Homes in a Special Flood Hazard Area need flood-resistant design and substantial improvement documentation. The county Flood Department is at floodinfo@mypasco.net or 727-847-8126, option 4.
