Yes. In Florida, water heater replacement generally requires a permit, and Unincorporated Hillsborough County is no exception.

Florida and local notes for Unincorporated Hillsborough County
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. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities. Hillsborough County's HB 803 exemption does not apply to plumbing or gas work, and the county's plumbing exemptions are limited to stopping leaks, clearing stoppages, and cleaning septic tanks. The county lists the replacement of water supply or gas piping and mechanical equipment among repairs that are not minor and do require a permit. In an emergency, the county allows the permit application to be submitted within the next working business day after the equipment is replaced.
