Water Heater · Kandiyohi County, Minnesota
Permit required
In Minnesota, a Water Heater requires a plumbing permit.
Replacing a water heater requires a plumbing permit and inspection; even a same-fuel, same-size swap generally needs one, with the T&P valve, drain pan, and expansion tank checked. Switching fuel type, relocating the tank, or going tankless also triggers gas or electrical permits. Plans are reviewed under the Statewide code (IRC 2018); apply through Kandiyohi County Public Works before work begins.
