Do I need a permit for standby generator installation in Unincorporated Hillsborough County?

Permit required

Yes. In Florida, standby generator installation generally requires a permit, and Unincorporated Hillsborough County is no exception.

A permanently installed standby generator requires an electrical permit for the transfer switch, plus a gas or fuel permit for natural gas or propane connections, and often a building or structural review because the unit must be anchored for wind uplift. Portable generators are not permitted work, but any hard-wired or fuel-connected unit is. Propane tanks have separate siting rules.

Florida and local notes for Unincorporated Hillsborough County

Requirements are multi-agency and can include zoning, fire, and environmental review for fuel tanks. Signed and sealed plans and wind-load anchoring are often required. 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. A permanent generator involves electrical and, on gas units, fuel gas permits, plus setback review for the pad. Hillsborough County's Residential Backup Generators checklist requires two inspections, electrical rough-in and electrical final, and the final can be scheduled only after the rough-in passes. In a Special Flood Hazard Area the generator site plan must show the minimum required design flood elevation referenced to NAVD 1988. Under LDC 6.01.03, a generator or propane tank may not project into a required front yard, and may project only 5 feet into a required rear yard and the lesser of 3 feet or half of a required side yard.
