Do I need a permit for water heater replacement in Goodlettsville?
Most likely yes. Water heater replacement usually requires a permit in Tennessee. Confirm the specifics with Goodlettsville.
Replacing a water heater generally requires a permit; temperature-and-pressure relief valve, discharge piping, venting, and (for gas) combustion-air and flue requirements are enforced. Switching fuel type, relocating the unit, or converting to a tankless model can add mechanical/gas permit and inspection requirements; confirm locally. For the Davidson County portion of Goodlettsville, plumbing and gas/mechanical permits are obtained from the Metro Nashville Codes Department, so a water heater change-out is permitted through Metro Nashville rather than the city Building Department. Treat a water heater replacement as needing a permit and confirm with the Goodlettsville Codes office at 615-851-3741 and Metro Nashville Codes at 615-862-6500. Any change to the gas connection adds a separate gas/mechanical permit, so include the full scope when you apply.
