A South Carolina contractor license is granted based on your financial strength, and it requires you to carry workers compensation if state law requires it, meaning once you regularly employ four or more people whose prior-year wages totaled at least 3,000 dollars. With fewer than four employees you are exempt regardless of payroll. On top of that, general contractors and clients almost always require proof of general liability and workers comp before they let you on a job, so coverage is often the price of the work even below the state trigger.
Who this is for: South Carolina contractors getting or renewing a license, and figuring out which policies the state and their clients require.
The short version
- Commercial contractors are licensed by financial strength. The Contractor's Licensing Board places licensees in groups by working capital or net worth.
- Workers comp is required if the law requires it, which in South Carolina means four or more employees; fewer than four is exempt regardless of payroll.
- The license threshold is a per-project dollar amount, commonly reported at 5,000 dollars for commercial work; confirm the current figure with the board.
- Residential building is licensed separately by the Residential Builders Commission.
- Uninsured subs are your exposure. A general contractor can owe comp to an uninsured sub's injured worker.
What the license requires
South Carolina licenses commercial general and mechanical contractors through the Department of Labor, Licensing and Regulation Contractor's Licensing Board, and residential building through a separate Residential Builders Commission. Commercial work at or above a set dollar amount per project, commonly reported at 5,000 dollars, must be performed by a licensed contractor. Licensees are placed into financial groups by their working capital or net worth, and the group sets how large a single project they can take. Because the exact figures can change, confirm the current threshold and group limits with the board before you file.
| Financial group | Single-project limit (commonly reported) | Workers comp |
|---|---|---|
| Group I | Up to 100,000 dollars | Required if you meet the state trigger |
| Groups II to IV | Rising limits by working capital or net worth | Required if you meet the state trigger |
| Group V | Unlimited | Required if you meet the state trigger |
Workers comp and your headcount
The license ties workers comp to state law, and South Carolina law requires it once you have four or more employees regularly in service whose prior-year wages totaled at least 3,000 dollars. A business with fewer than four employees is exempt regardless of payroll. So a contractor at or above that trigger needs a policy for two reasons at once: the law mandates it and clients want proof of it. A contractor below the trigger with no employees is not forced by the comp law to carry it for the license itself, but is a very common voluntary buyer, because client contracts, general contractors, and the risk of an uninsured-sub claim all push toward having coverage anyway.
Why contractors carry comp before they must
Two forces pull South Carolina contractors into coverage early. First, the people who hire you, general contractors and commercial clients, routinely require proof of coverage before they let you on site, so a policy is often the price of the work. Second, if you act as a general contractor and hire subs, an uninsured sub can become your problem: South Carolina makes an upper-tier contractor the statutory employer of an uninsured sub's injured workers, so you can owe comp on a job you control. There is relief if a sub gave you a certificate that turned out to be false, but the clean protection is to collect a current certificate of coverage from every sub and carry your own policy.
A Charleston example
Illustrative, not a quote. A Charleston general contractor holds a commercial license in a financial group that matches its project size and shows proof of general liability and workers comp to keep it. With four employees, the contractor needs workers comp under state law, so the license and the law line up. Before a framing sub starts, the contractor collects the sub's certificate of coverage, so an injury on that crew does not fall back on the general contractor's policy.

Why do general contractors require subs to carry workers comp?
Because in South Carolina a general contractor can be the statutory employer of an uninsured sub's injured workers and owe them benefits. Requiring a certificate from every sub keeps that exposure off your policy.
Do I need coverage if I have no employees?
Not by the comp law for the license itself, but general contractors and clients routinely require proof of coverage before you can work, so many owner-only contractors carry a minimal policy anyway.
Why South Carolina owners choose Morrow
- We shop the right market for you. In South Carolina you buy workers comp on the open market from any private insurer licensed in the state, because South Carolina has no state fund. If no carrier will take you, the NCCI-run assigned risk plan is the guaranteed fallback, and larger employers can apply to self-insure with approval from the state. We shop the licensed carriers so you are not stuck paying the fallback plan's higher rate.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
