Do I need a permit for water heater replacement in Greenville?
Yes. In South Carolina, water heater replacement generally requires a permit, and Greenville 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. Greenville's plumbing exceptions cover clearing stoppages and repairing leaks, but the city states that if a concealed pipe becomes defective and must be replaced with new material, the work is considered new work and a permit shall be obtained, so a water heater change-out generally needs a Plumbing Permit. A gas water heater adds a gas service connection, which falls under the city's Mechanical Permit Application, so confirm whether that scope applies. For an emergency replacement, the permit application is submitted the next working business day; this site is not a government agency, so confirm requirements with the Building and Permit Center at 864-467-4505.
