Do I need a permit for water heater replacement in Port St. Lucie?

Permit required

Yes. In Florida, water heater replacement generally requires a permit, and Port St. Lucie is no exception.

Whether a water heater swap needs a permit depends on your jurisdiction and the unit. Some jurisdictions exempt a small like-for-like electric replacement, while others require a plumbing permit for any change-out. Any gas water heater, any increase in size or wattage, or any relocation triggers a plumbing or gas permit almost everywhere.

Florida and local notes for Port St. Lucie

St. Lucie County's own permitting office is the St. Lucie County Building & Code Regulation Division, reachable on (772) 462-1553 at https://www.stlucieco.gov/departments-and-services/planning-and-development-services/permitting-zoning. 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.
