Water Heater · Seneca County, New York
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.

NYC) code (IRC 2024); apply through Seneca County Buildings & Grounds before work begins.
