South Carolina Contractor & Trade License Requirements

South Carolina requires statewide licensing for general contractors, electricians, plumbers, HVAC contractors, and roofing contractors. Commercial work over $10,000 is regulated by the SC Contractors' Licensing Board (CLB) under LLR, with five license groups based on financial qualifications. Residential work over $200 (builders) or $200 (specialty trades) is regulated by the Residential Builders Commission (RBC). Electricians, plumbers, and HVAC contractors need separate residential specialty licenses for residential work. As of January 1, 2026, the Carolinas AGC (CAGC) replaced MASC as the trade certification provider for master electrician and master plumber certifications.
