Do you need a permit for Water Heater in Hays County?
In Texas, 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 exceed) code (IRC 2021); apply through Hays County Development Services before work begins.
