Do I need a permit to replace a water heater in Kentucky?
What that means for Richmond and Lexington homeowners
If your tank is leaking, rusting out, or being upgraded to tankless, the replacement is not just a swap-and-go job. Kentucky treats water-heater replacement as permitted plumbing work, and 815 KAR 20:055 also says the water heater must be properly connected and accessible for inspection, repair, and replacement.
The practical reason is safety. A water heater touches potable water, temperature, pressure, relief-valve discharge, sometimes gas, sometimes electrical, and sometimes venting. Those details need to follow Kentucky code and the manufacturer's manual.
Safe next step
Use a licensed plumber before the install starts. If you are in Richmond, Lexington, Madison County, Fayette County, or nearby Central Kentucky, Clog Busterz can handle the replacement and dispatch the right crew.
