South Carolina contractor workers' comp is priced by one formula: (payroll ÷ 100) × class-code rate × experience mod. In 2026 that means a small, clean-record trade contractor might pay a few thousand dollars a year, while a mid-size framing, roofing, or concrete operation with real payroll can pay tens of thousands to well over $100,000. The class code and payroll drive the number far more than the fact that you're in South Carolina — but the state's tighter post-2024 market affects who will quote you.
Every workers' comp premium starts the same way. Take your annual payroll, divide by 100, multiply by the rate for your class code, then multiply by your experience modification factor. A roofer and a finish carpenter with identical payroll pay dramatically different premiums because roofing is one of the highest-rated class codes and finish carpentry is far lower. That's why "what does workers' comp cost" always comes back to what work do you actually do, and how much payroll runs through it.
South Carolina's 2024 tort reform and the broader hardening of the construction insurance market have made some carriers more cautious about South Carolina contractor risk. The pressure shows up most on the liability side, but it shapes how whole programs get packaged and priced — and it means some SC contractors, especially those with prior claims, higher-hazard trades, or a recent non-renewal, find fewer standard markets willing to quote. When the standard market pulls back, coverage often moves to specialist carriers or surplus lines, and it takes an agency that knows which doors are still open. This is exactly the gap we built our South Carolina contractor practice around.
South Carolina generally requires businesses with four or more employees (including part-timers) to carry workers' comp, with some exemptions. But headcount is rarely the deciding factor for contractors — general contractors and project owners routinely require proof of coverage regardless of your size. In practice, most South Carolina contractors carry workers' comp because their contracts demand it, not because they've counted to four. Confirm current rules with the South Carolina Workers' Compensation Commission and read your contract requirements.

In a hardening market, the goal isn't just the lowest number — it's a program that actually gets bound, audited fairly, and won't be non-renewed next year. A rock-bottom quote from a carrier with no appetite for South Carolina construction can evaporate at renewal and leave you scrambling mid-project. The right question is "which carrier genuinely wants my trade in South Carolina, at a mod and classification that hold up at audit" — and answering it is what an independent agency is for.

Generally for businesses with four or more employees, including part-timers, with some exemptions. Most contractors carry it regardless because their contracts require proof of coverage.
Class code (the trade), total payroll, and the experience mod. Subcontractor certificates, classification accuracy, and safety programs also move the number.
The 2024 tort reform and a hardening construction market made some carriers more cautious about SC contractor risk, so some contractors need a specialist agency or surplus lines to get quoted.
Yes. Uninsured subs can have their payroll charged back to your policy at audit. A current certificate of insurance from every sub prevents that.
Many general contractors and public owners cap the mod (often 1.00 or 1.25) to qualify to bid, so a high mod can cost you jobs, not just premium.
