Do I need a permit for water heater replacement in Mauldin?

Permit required

Yes. In South Carolina, water heater replacement generally requires a permit, and Mauldin is no exception.

A straight water heater replacement still requires a permit in South Carolina jurisdictions. The inspector checks the temperature and pressure relief valve, discharge piping, drain pan and any expansion tank. Switching from a tank to a tankless or changing the fuel or venting adds gas, electrical or mechanical requirements. Confirm scope before buying the unit. Mauldin explicitly requires a permit before adding or replacing any water heater, so a water heater change-out is permitted work rather than an exempt minor repair. A gas water heater adds a fuel gas scope, so confirm whether a separate gas permit and inspection apply to your replacement. This site is informational and not a government agency, so confirm current water heater permit requirements with Mauldin Building and Zoning at (864) 234-3475.
