South Carolina Hvac Legislation, Codes, and Guidelines

State Statutes and Adopted HVAC Codes

In South Carolina, building codes are mandated by the state legislature and enforced at the local level. The state utilizes the International Code Council (ICC) family of codes as the foundation for its statewide standards. As of the most recent major update effective January 1, 2023, South Carolina has adopted the 2021 editions of the International Codes, including the International Mechanical Code (IMC) and the International Residential Code (IRC), with specific South Carolina-approved modifications. These codes establish the minimum requirements for the design, installation, maintenance, and inspection of HVAC systems in residential, commercial, and industrial buildings.

Primary State Agency

The South Carolina Building Codes Council is the primary state body responsible for adopting, modifying, and overseeing the implementation of these building codes. The Council, which operates under the South Carolina Department of Labor, Licensing and Regulation (LLR), reviews ICC code editions and determines necessary state-specific amendments to address local environmental and construction conditions. While the Council sets the standards, the actual enforcement of these codes is carried out by local jurisdictions (cities and counties), which are required to employ certified building officials to conduct plan reviews and field inspections.
