Do you need a permit for Water Heater in Seneca County?
In New York, 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 (exc. NYC) code (IRC 2024); apply through Seneca County Buildings & Grounds before work begins.
