Whether a water heater swap needs a permit depends on your jurisdiction and the unit.

Florida and local notes for Unincorporated Hernando County

Hernando County's own permitting office is the Hernando County Building Division, reachable on 352-754-4050 at https://www.hernandocounty.us/building-development/building/. Its online permit portal is https://www.hernandocounty.us/CivicAccess. 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. Hernando County lists a water heater change out of the same type and in the same location as an item not requiring a building permit. Changing fuel type or moving the heater takes it off that list. Exempt plumbing work under local FBC 105.2 may only be done by a licensed plumbing contractor or the property owner under s. 489.103(7), Florida Statutes, whether or not a permit is required.
