Do I need a permit for plumbing fixture or repiping in Marathon?
Yes. In Florida, plumbing fixture or repiping generally requires a permit, and Marathon 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 Marathon
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. Monroe County's own permitting office is the Monroe County Building and Permitting Department, reachable on 305-289-2501 at https://www.monroecounty-fl.gov/149/Building-and-Permitting. Its online permit portal is https://www.monroecounty-fl.gov/1278/Online-Permitting-Services. 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. The rough inspection has to happen before walls are closed, so confirm scheduling lead time when you pull the permit. Marathon permits are handled by the Marathon Building Department, reachable on 305-289-5052 at https://www.ci.marathon.fl.us/building. Its online permit portal is https://marathonfl.viewpointcloud.com. Monroe County also issues permits for the unincorporated county, and many smaller Florida municipalities contract building services to it rather than running a department of their own, so confirm which office covers your address before you apply.
