Contractor Licensing Requirements in South Carolina
South Carolina licenses contractors through two separate bodies depending on project type: the Contractor’s Licensing Board handles commercial and general contracting, while the Residential Builders Commission covers home builders and residential specialty trades. Both require passing exams and documenting experience, and South Carolina is one of the states that accepts the NASCLA Accredited Exam for commercial licensure.
South Carolina’s Contractor Licensing System
Commercial and general contracting work above the state’s dollar threshold requires a license from the Contractor’s Licensing Board, sorted into financial groups based on working capital and net worth. Residential builders and specialty trades are instead licensed through the Residential Builders Commission, with separate thresholds and exams for that side of the industry.
License Classes in South Carolina
- Commercial General/Mechanical Contractor — assigned to Financial Groups I through V based on capital and project size limits
- Residential Builder — for homebuilders constructing or improving residential structures
- Residential Specialty Contractor — for trade-specific residential work above a lower dollar threshold
- NASCLA-endorsed Commercial General Building Contractor track for those holding the national accredited exam
Exam & Experience Requirements
Commercial applicants must pass the South Carolina Business Management and Law exam plus a trade/technical exam tied to their classification, and must document two years of relevant experience within the past five years under a Primary Qualifying Party. Residential Builder applicants take both a technical exam and a Residential Business and Law exam, backed by at least one year of verifiable experience under a licensed contractor.
NASCLA Reciprocity
South Carolina is a NASCLA-participating state — it accepts the NASCLA Accredited Examination for Commercial General Building Contractors in place of its own trade exam, though applicants still must pass South Carolina’s separate Business and Law exam.
Bonding & Insurance to Get Licensed
Residential Builders must carry a minimum $15,000 surety bond or equivalent proof of financial responsibility, and Residential Specialty contractors need a bond once a job exceeds $5,000 in labor and materials. General liability insurance is also expected alongside licensing for both commercial and residential contractors.

Reciprocity with Other States
South Carolina participates in the NASCLA reciprocity network, accepting the NASCLA Accredited Exam for its commercial general building contractor track, which streamlines licensing for contractors already NASCLA-certified in another participating state.
