Do I need a permit for plumbing fixture or repiping in Unincorporated Miami-Dade County?
Yes. In Florida, plumbing fixture or repiping generally requires a permit, and Unincorporated Miami-Dade County is no exception.
Repiping, meaning replacing supply, drain, waste, or vent piping, requires a plumbing permit in Florida. A straightforward like-for-like replacement of a faucet, sink, or toilet, and clearing stoppages or fixing leaks, is generally exempt as long as no pipe or valve is moved or replaced. As soon as concealed pipe must be removed and replaced, it is treated as new work that needs a permit.

Local and county notes for Unincorporated Miami-Dade County
A like-for-like fixture swap with no change to the pipes is generally exempt under the Florida Building Code. It becomes permit work the moment you move or replace a pipe or valve. When in doubt, confirm with your building department. Repiping and moving or replacing pipe require a plumbing permit statewide. Water-service line replacement also needs a permit. 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.
