Water Heater permit in Miami, FL
Yes — you need a permit for water heater work in Miami.
You need a plumbing permit to replace or relocate a water heater. Miami lets a licensed plumbing contractor repair or replace gas appliances without a permit at any price, but the code names the water heater as the one appliance left out of that exemption. The separate exemption for licensed plumbing work under $2,500 in materials and labor covers repair work, not swapping the unit. If the heater fails and the replacement cannot wait, the work may go ahead, but the permit application must be filed the next business day.
