Do I need a permit for water heater replacement in Lexington?
Yes. In South Carolina, water heater replacement generally requires a permit, and Lexington 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. Lexington permits are handled by the Lexington Planning and Building Department, reachable on 803-356-5938 at https://www.lexsc.gov/871/Planning-Building. Lexington County runs its own building permit office as well, so confirm whether Lexington or the county handles your address before you apply. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities.
