ExploreAbout this exam
The South Carolina Contractor's Licensing Board, a unit of the SC Department of Labor, Licensing and Regulation (LLR), regulates the license, certification or registration of general and mechanical contractors, construction managers, burglar alarm and fire alarm contractors, fire sprinkler contractors, and the boiler safety program. The General Contractor credential is aimed at individuals and firms that contract to build, alter or repair structures for others, and it requires applicants to show both trade knowledge and business competence before the Board. The examination is a multiple-choice test sampling five areas: business and project management; contract administration and bidding; estimating and plan reading; construction methods, materials, and site work; and safety, codes, and regulatory compliance. Expect arithmetic-heavy items in the estimating portion, scenario items in contract administration, and code-referenced items in the safety portion. To prepare, work each domain in turn but weight study time toward your weakest area rather than the largest, read the Board's posted statutes and regulations (including the posted modifications to the Contractor's Practice Act, H.4115), and confirm current exam logistics with the Board or, for classifications examined by PSI, the PSI Candidate Information Bulletin.

What you'll study
About SC General Contractor preparation
What does the SC Contractor's Licensing Board actually regulate?
The Board regulates the license, certification or registration of general and mechanical contractors, construction managers, burglar alarm and fire alarm contractors, fire sprinkler contractors, and the boiler safety program. The Boiler Safety Program is supervised by the Board. It is housed within the SC Department of Labor, Licensing and Regulation (LLR).
Is the exam multiple choice, and how long do I get?
The Board's public site does not publish item counts, time limits, or scoring rules. For classifications examined through PSI - the Nonstructural Renovation classification has required a PSI technical exam since 01/01/2025 - the PSI Candidate Information Bulletin is the authoritative source on format. Confirm your own classification's logistics with the Board at (803) 896-4686.
What passing score do I need, and what does a retake cost?
Those figures are set by the Board and the exam administrator and are not published on the pages summarized here. Do not rely on forum numbers. Request the current passing standard, retake waiting period, and any retake fee directly from the Board or from the PSI Candidate Information Bulletin before you schedule.
When is license renewal due?
The 2026-2028 General Contractor license renewals are currently open, per the Board's alert. For Burglar Alarm, Fire Alarm, and Fire Sprinkler Contractor licenses, the 2026-2028 renewal window is also open and the deadline to renew without a late penalty is July 31, 2026. Renewal is handled through the Board's online licensing tools.
In what order should I study the five domains?
Take a short diagnostic first, then front-load your weakest domain rather than the one you enjoy. A practical sequence is plan reading and estimating together, then construction methods, then contract administration and bidding, then business management, finishing with safety and code compliance. Re-cycle through all five in the final weeks instead of studying one domain to exhaustion.
What are the most common ways candidates lose points?
Three repeat offenders: skipping units and conversions in estimating problems, answering contract questions from intuition instead of the stated contract terms, and treating safety items as general knowledge rather than code-specific requirements. A fourth is misreading the question stem - items asking for the exception or the least appropriate option are frequently missed under time pressure.
How math-heavy is the estimating and plan reading section?
Expect quantity takeoffs, area and volume calculations, waste and conversion factors, and simple productivity or cost problems. Bring disciplined habits: write the formula, keep units visible, and sanity-check the magnitude of every answer. Most errors in this section are unit and decimal-place mistakes, not conceptual ones.
How do I contact the Board with a licensing question?
The Contractor's Licensing Board lists [email protected] and telephone (803) 896-4686, with offices at 110 Centerview Dr, Columbia, SC. LLR's main Columbia location is Synergy Business Park, Kingstree Building, 110 Centerview Dr., Columbia, South Carolina 29210, (803) 896-4300, with office hours 8:30am to 5:00pm.
Where do I find the statutes, regulations, and recent law changes?
The Board page links Statutes and Regulations for general and mechanical contractors, plus a Board FAQ and Board Orders. Important Information on Modifications to the Contractor's Practice Act (H.4115) is posted on the Board page. Read the posted modifications before your exam - exam content tracks the current statute, not older study guides.
Is this study page run by the State of South Carolina?
No. This is an independent study resource with no affiliation with, or endorsement by, the SC Contractor's Licensing Board or LLR. All licensing decisions, fees, deadlines, and exam logistics come from the Board. Always verify a requirement against the Board's own published material before acting on it.
