Do I need a permit for plumbing fixture or repiping in Unincorporated Martin County?
Unincorporated Martin County does not issue residential building permits. Martin County has no county building department and issues no residential building permit. The Indiana Department of Homeland Security (IDHS) Local Building Officials directory (Martin County report, printed 9/27/2026) lists no local building official for 'All Areas Not In Jurisdictions Listed Below', only the IDHS state inspector (Matthew Prost, 317-232-1407), who handles Class 1 (commercial) structures; the state does not issue permits for one- and two-family dwellings. The county's official site lists no building, planning, or zoning office. The Martin County Health Department issues septic permits. The state residential code still applies to the work.
The requirements below come from Indiana rules and describe the standard the work must still meet. They are not a statement that Unincorporated Martin County will issue you a permit.
Most likely yes. Plumbing fixture or repiping usually requires a permit in Indiana. Confirm the specifics with Unincorporated Martin County.
Work that moves or replaces pipes, rather than swapping a fixture, alters the plumbing system itself and is not covered by fixture replacement exemptions. Pipe work normally requires a plumbing permit, a pressure or air test, and a rough in inspection before walls are closed, and many jurisdictions require a licensed plumber to pull the permit. Plumbing for dwellings follows Chapters 25 to 32 of the 2020 Indiana Residential Code, and compliance with the Indiana Plumbing Code (675 IAC 16, 2012 edition based on the 2006 IPC) is allowed instead. Anyone acting as a plumbing contractor or journeyman must hold a state license (IC 25-28.5-1-11); the owner-occupant exemption in IC 25-28.5-1-32 covers work on the owner's own dwelling of eight or fewer units. The state does not issue permits for or inspect one- and two-family dwellings; if the local unit has no building permit ordinance, no state office issues one instead, but the 2020 Indiana Residential Code still applies to the work.
