Do I need a permit for water heater replacement in Unincorporated Marinette County?

Unincorporated Marinette County does not issue residential building permits. Marinette County is not on the DSPS list of counties delegated to enforce the Uniform Dwelling Code, so the county issues no residential building (UDC) permit. Every Wisconsin town, village and city is covered by the state UDC: a town with its own delegated UDC program issues the permit itself; in a town without one, the DSPS permitting map directs homeowners to the Wisconsin Department of Safety and Professional Services (DSPS) (608-261-6541).

The requirements below come from Wisconsin rules and describe the standard the work must still meet. They are not a statement that Unincorporated Marinette County will issue you a permit.

Permit may be required

It depends. Whether water heater replacement needs a permit in Unincorporated Marinette County comes down to the details of your project.

Plumbing must be installed by licensed plumbers under a master plumber, except that an owner may do plumbing in a one-family building the owner owns and occupies as a home unless a local ordinance requires a license (Wis. Stat. 145.06(4)(a)). Under SPS 382.21 testing is waived only where the job adds, replaces, alters or relocates no water distribution, drain or vent piping; otherwise the work must be tested and inspected. Whether a permit is required for a like-for-like replacement is set by local ordinance. A gas fired water heater, a change in size, or a move to a new location falls outside like for like exemptions, which cover a same size electric unit reinstalled in the same place. Gas work normally needs its own mechanical or gas permit and a pressure test, and relocating the unit can change venting, combustion air, drain pan, and expansion tank requirements.
