What Are South Carolina's Contractor Licensing Rules?

Is a contractor license required in South Carolina?

Yes, and the threshold depends on what kind of work it is. Commercial and general contracting — including mechanical trades like electrical, plumbing, and HVAC performed on commercial projects — require a license once the total cost of construction exceeds $10,000. On the residential side, a residential builder license is required once a project exceeds $5,000, and a residential specialty license or registration is required once specialty work (roofing, electrical, plumbing, HVAC, carpentry, masonry, and similar trades) exceeds $500. These are genuinely separate systems with separate thresholds, not one rule applied two ways.

Which agency regulates it?

Two separate boards, both under the Department of Labor, Licensing and Regulation (LLR). The Contractor's Licensing Board handles commercial and general contracting, including electrical, plumbing, and HVAC as mechanical contractor classifications within that same system. The Residential Builders Commission handles residential builders and residential specialty contractors — including electrical, plumbing, and HVAC again, but as a completely separate licensing track for residential work specifically.

Where can you find the actual laws?

Commercial and general contracting is South Carolina Code Title 40, Chapter 11 — the licensing threshold is § 40-11-30, the qualifying party requirements are § 40-11-230, and the criminal penalty is § 40-11-200. Residential contracting is Title 40, Chapter 59 — thresholds are § 40-59-20, the penalty for unlicensed practice specifically is § 40-59-30, and reciprocity sits in § 40-59-220. The Contractor's Licensing Board and the Residential Builders Commission each publish their own licensing guidance directly.

What does it take to get licensed?

For commercial licensing, the qualifying individual needs at least two years of experience within the past five years in the specific classification, a passing score of 70% or better on South Carolina's law exam, and a classification-specific trade exam where one is required. The business itself has to meet a financial requirement tied to one of five license groups, ranging from $20,000 in net worth for a license capped at $100,000 bids, up to $350,000 in net worth for an unlimited license — working capital or an equivalent surety bond can substitute for net worth. For residential licensing, a builder needs at least one year of supervised experience (or an approved combination of education and experience), the applicable technical and business/law exams, a $15,000 bond or equivalent proof of financial responsibility, and a credit report. Specialty trades vary by classification — electrical, plumbing, and HVAC require a full license, while some other residential trades only require registration.

What are the penalties for operating without a license?

Real on both sides, and notably stricter on the residential side than the commercial side. Unlicensed commercial contracting is a misdemeanor carrying up to one year in jail or a fine of up to $5,000, plus separate administrative citations starting at $500 for a first violation and escalating from there, and the board can impose its own civil penalties of up to $5,000 per violation. An unlicensed commercial contractor also can't sue to enforce a construction contract at all. On the residential side, practicing without a required license is punished more severely: a fine of $500 to $10,000, or imprisonment of at least 30 days, or both — on top of disciplinary fines, cease-and-desist orders, and injunctions the Residential Builders Commission can pursue separately.

Does South Carolina have reciprocity with other states?

Yes, but only as a trade-exam waiver, not an automatic license transfer, and only for commercial licensing. South Carolina currently waives its technical exam for applicants holding a qualifying license from Alabama, Georgia, Louisiana, Mississippi, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, or Utah. Every incoming applicant still has to pass South Carolina's own Business, Law and Project Management exam, and a license obtained through grandfathering or another state's own exam waiver doesn't qualify for South Carolina's waiver either. A separate waiver process exists for residential licensing, though it runs through its own, independent approval process rather than the commercial list above.

Is it legal to rent or lease a license in South Carolina?

No. "Qualifying Party" and "Primary Qualifying Party" are South Carolina's actual statutory terms for commercial licensing, and the law is specific about what real involvement that role requires: the primary qualifying party must serve in a management position, be actively involved in the business's management, supervision, and operations, and be "an integral party of the applicant's business and the work undertaken by the applicant." They can't take on outside work that would conflict with those duties or limit their ability to actually supervise the licensed work. One person can qualify a second business, but only if both businesses operate from the same location, the qualifying party is involved in both daily, earns a living from both, holds an ownership interest in both, and owns at least 50% of one of them — all five conditions have to be true at once, which rules out collecting a fee to qualify unrelated businesses. If a qualifying party leaves, the business has 15 days to notify the state and 90 days to name a replacement before the license is suspended. Letting an unlicensed entity use a license is explicitly listed as grounds for discipline, and the board can hold the qualifying party personally responsible for violations, not just the business.
