Do I need a permit for interior remodeling in Unincorporated Hillsborough County?
It depends. Whether interior remodeling needs a permit in Unincorporated Hillsborough County comes down to the details of your project.
Cosmetic interior work such as painting, flooring, cabinets, and drywall patching generally does not need a permit, while remodeling that involves electrical, plumbing, mechanical, gas, or structural changes does. Florida HB 803, effective July 1 2026, exempts single-family work under $7,500 from a building permit, but it excludes those five trades and does not apply in flood-hazard areas. Most permit-worthy remodels involve one of those trades.
Local detail for Unincorporated Hillsborough County: Building permits for all unincorporated areas (including Sun City Center) are handled by Hillsborough County Development Services. Online applications submitted via the HillsGovHub portal (Accela).
Florida and local notes for Unincorporated Hillsborough County
Electrical, plumbing, mechanical, gas, and structural work still need a permit regardless of cost. HB 803 bars splitting a project to stay under $7,500 and does not apply in flood-hazard areas. Local departments implement HB 803 individually, so confirm the policy in your jurisdiction. Hillsborough County's own permitting office is the Hillsborough County Development Services Department, reachable on (813) 272-5600 at https://hcfl.gov/businesses/permits-and-records. Its online permit portal is https://aca-prod.accela.com/HCFL/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. Each trade normally needs its own permit on top of the building permit, so ask which trade permits your scope will require. Hillsborough County treats painting, tile, floor coverings, shelving, cabinet work, and wallpaper as work that needs no permit, but a contractor hired for painting or tile must still be licensed. The county says a bathroom remodel involving plumbing would likely require a permit, and cutting any wall or partition, removing a load-bearing support, or altering piping, wiring, or mechanical equipment is not a minor repair. If work has started without a required permit, the county says to stop and contact permitting@hcfl.gov for an after-the-fact permit, and citations can reach $500 per violation.
