Do I need a permit for plumbing fixture or repiping in Unincorporated Lyon County?
Unincorporated Lyon County does not issue residential building permits. Lyon County has not adopted the Minnesota State Building Code for its unincorporated area: the Minnesota Department of Labor and Industry jurisdiction directory (https://workplace.doli.state.mn.us/jurisdiction/, search by county) lists all 20 townships and unorganized areas in Lyon County with 'HAS ADOPTED THE BUILDING CODE: NO', so no building code permit or inspection is issued there. Lyon County Planning and Zoning issues zoning permits in the unincorporated area. Electrical work still needs a state electrical permit from the Minnesota Department of Labor and Industry.
The requirements below come from Minnesota rules and describe the standard the work must still meet. They are not a statement that Unincorporated Lyon County will issue you a permit.
Most likely yes. Plumbing fixture or repiping usually requires a permit in Minnesota. Confirm the specifics with Unincorporated Lyon County.
Replacing or altering water supply, drain, or vent piping is not an ordinary repair (Minn. R. 1300.0120, subp. 6), and new or altered piping must be tested and approved before use (Minn. R. 1300.0215). Paid plumbing work requires DLI-licensed plumbers and a plumbing contractor license (Minn. Stat. 326B.46); an owner-occupant may do their own plumbing unless a local ordinance forbids it. DLI does not issue residential plumbing permits in areas without a local code program, so confirm who, if anyone, inspects plumbing for the address. 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.
