Do I need a permit for water heater replacement in Miami?
Yes. In Florida, water heater replacement generally requires a permit, and Miami 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.
Local and county notes for Miami
Gas water heaters, larger units, and relocations require a plumbing or gas permit. The HB 803 $7,500 exemption does not cover plumbing or gas work. Some jurisdictions exempt a small like-for-like electric water heater swap, while others require a plumbing permit for any change-out. Confirm with your building department before you skip a permit. Water heaters are specifically excluded from the City of Miami repair exemptions (the gas appliance repair exemption does not cover water heaters), so a water heater replacement always requires a permit. Water heater replacement is a named permit category and typically qualifies for the City of Miami Easy Permit program for a licensed contractor in good standing. Confirm whether an electrical or gas sub-permit is also needed depending on the water heater type before scheduling the work. Every address in this county sits inside the Florida Building Code High Velocity Hurricane Zone, the strictest wind construction standard in the state, so materials and methods face requirements that do not apply elsewhere in Florida. Your city issues the permit, not the county. Miami-Dade County's own building department serves the unincorporated area, while each municipality runs its own building department, and the county Board of Rules and Appeals interprets the code across all of them.
