South Carolina Contractor License Exam Prep
South Carolina contractors are licensed by the SC Contractor's Licensing Board (LLR). Most classifications sit a trade paper plus Law & Business. Need only the business paper? It is sold standalone. If you buy a South Carolina classification that sits that exam, that paper is 75% off where we offer it.
Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

Contractor Pathway offers an original, exam-focused study guide and four full-length practice exams for every South Carolina classification that requires a state board exam — currently 4 courses across Electrical, HVAC / Mechanical and Building / General Contractor. Choose your classification below and study with 30-, 60-, or 90-day access at $99, $129, and $169. Many South Carolina classifications also require passing a separate Business & Law exam — and that course is 75% off with any trade course in your cart for the matching term.

How to get licensed in South Carolina
South Carolina splits commercial and residential work between two bodies at the Department of Labor, Licensing and Regulation: the Contractor’s Licensing Board for general and mechanical contractors, and the Residential Builders Commission for residential work. Which one you deal with depends on the building, not on your trade.
- Commercial work over $10,000 needs a General or Mechanical licence. A General or Mechanical Contractor’s licence is required for anyone performing commercial construction over $10,000 in South Carolina.
- Residential work is defined by size and cost. A residential builder constructs or superintends the construction, repair or improvement of a residential building not over three floors in height with no more than sixteen units in any single apartment building, where the cost of the undertaking exceeds $5,000.
- Show two years of recent, relevant experience. All applicants must submit at least two years of work experience performed within the past five years for the requested classification or subclassification — the exception being waiver and reciprocity applicants. Experience must match the classification sought, not construction generally.
- Everyone sits Business Management and Law. Applicants qualify by technical examination where one is required, by exam waiver/reciprocity, or by MASC certification — and in every case must also pass the S.C. Business Management and Law for Commercial Contractors examination.
- Your financials set your bid limit. A financial statement or a surety bond must be submitted to determine your licence group limitation. If you submit a financial statement, you must meet either the net worth/total equity requirement or the working capital requirement. Limits per bid and per job follow from that documentation — so the financial package decides the size of work you may legally pursue.

South Carolina contractor licensing — FAQ
Who licenses contractors in South Carolina?
The South Carolina Department of Labor, Licensing and Regulation (LLR) – through the Contractor’s Licensing Board for commercial work and the Residential Builders Commission for residential work.
What exams does South Carolina require?
Two PSI exams: the SC Business Management and Law exam (50 questions, 140 minutes) plus a trade exam for your classification (for example, the Building trade exam is 115 questions over 330 minutes). The passing score is 70% on each.
Are the South Carolina exams open book?
Yes. The commercial contractor exams are open book – you may bring, highlight, and index the references listed in the exam bulletin. The NASCLA Contractors Guide to Business, Law and Project Management (South Carolina edition) is the primary reference for the Business and Law exam.
How much do the South Carolina exams cost and can I retake them?
Each PSI exam part is $110, paid on the day of testing. A failed part can be retaken individually after a 30-day waiting period for a new $110 fee, so first-attempt preparation saves both time and money.
How long should I study for the South Carolina exam?
Most candidates do well on a 30-, 60-, or 90-day plan depending on experience, which is why we offer access at all three terms ($99 / $129 / $169). Each guide includes a day-by-day study plan.
