These standards are mandatory for all municipalities and counties across the state, effective as of January 1, 2023.

Primary Regulatory Agency

The South Carolina Building Codes Council is the primary state body responsible for the adoption and modification of building codes, including plumbing standards. The Council is composed of public and private building industry officials appointed by the governor. Its functions include reviewing model codes published by the International Code Council (ICC), voting on their adoption for use in South Carolina, and determining necessary state-level modifications. Local jurisdictions are responsible for the enforcement of these state-mandated codes through their respective building departments and certified building officials.
