Water Heater · Laurel County, Kentucky
Permit required
In Kentucky, 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 (local may vary) code (IRC 2015); apply through London Building Inspector before work begins.
