Do I need a permit for water heater replacement in Gainesville?

Permit required

Yes. In Florida, water heater replacement generally requires a permit, and Gainesville 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 Gainesville

Alachua County's own permitting office is the Alachua County Building Division, reachable on 352-374-5243 at https://growth-management.alachuacounty.us/building. Its online permit portal is https://www.citizenserve.com/alachuacounty. 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. Gainesville's Permit Exemption excludes electrical, mechanical, plumbing, and gas work, so this trade work needs its own permit regardless of cost. The code fee for each electrical, plumbing, gas, or mechanical permit is $72.50 (Appendix A). The Building Division offers virtual inspections by FaceTime or Skype for water heater changeouts. A gas water heater also falls under the Gas Checklist, which asks for venting, combustion air, and a riser diagram with all appliances and BTU ratings.
