Replacing a water heater in Florida requires a permit — in practically every city and county in the state. Like elsewhere, the permit is not about the tank itself; it covers the plumbing, electrical or gas, and pressure-relief work that comes with the swap. And yes, that includes a straightforward like-for-like change-out.
Florida does not have a California-style statewide energy form to fill out for a water heater, which makes the process feel lighter. But the Florida Building Code still governs the install, and the city-versus-county question decides where you file.
Do You Need a Permit?
Yes. A plumbing permit is required to install or replace a water heater throughout Florida, and electric and heat pump units typically need electrical work permitted too. There is no exemption for putting back the same unit.
What Florida Requires
Plumbing permit (always)
Florida jurisdictions require a plumbing permit to install or replace a water heater, change-outs included. The Florida Building Code governs the relief valve, discharge piping, and drain pan.
Electrical permit (electric & heat pump)
Electric and heat pump water heaters usually also need an electrical permit for the dedicated circuit and disconnect. Many offices handle this as a combination permit.
Expansion tank & drain pan
Where required, a thermal expansion tank and a properly routed drain pan are inspection items. Missing either is a common correction.
Tankless and exterior installs
Tankless units add gas-sizing and venting considerations, and exterior installations in South Florida may bring wind and mounting requirements into play.
Who Issues Your Permit
As with most Florida permitting, it comes down to incorporated city versus unincorporated county. Cities like Miami, Fort Lauderdale, Orlando, and Tampa run their own building departments and online portals; unincorporated addresses go through the county. Confirm the jurisdiction before you file — filing with the wrong office is the most common avoidable delay.
What Inspectors Check
- Temperature-and-pressure (T&P) relief valve and discharge piping
- Drain pan and proper routing to an approved location
- Correct electrical connection and a working disconnect, or a proper gas connection and venting
- Thermal expansion tank where required
- Secure mounting and clearances, especially for tankless or exterior units
Where Contractors Get Rejected
- Wrong jurisdiction. Filing with the county when the address is inside a city, or vice versa.
- Missing expansion tank or drain pan detail. A frequent correction on otherwise clean installs.
- Licensing not on file. The issuing office needs your contractor registration recognized before it will issue, which can stall a first filing in a new city.
Filing Across Florida
If you replace water heaters across South Florida or the I-4 corridor, the work itself is routine — the friction is doing it through a dozen different city and county portals, each with its own login and record type. That repetitive filing is exactly what we automate. For the bigger picture on South Florida code, see our Miami-Dade and Broward permit guide, or the national overview of whether you need a permit to replace a water heater.
