Workers' Comp Insurance for Construction Businesses in South Carolina
Construction is one of the most heavily regulated and highest-rate industries for workers' compensation. Class codes vary widely depending on the type of work — residential carpentry, commercial framing, masonry, and concrete each carry different rates. Many states require coverage starting at one employee for construction, even when other industries are exempt below 3-5 employees in South Carolina. The South Carolina workers' compensation market is governed by NCCI, and the average rate statewide is approximately $1.34 per $100 of payroll.
South Carolina requirements for construction businesses

Why construction workers' comp is tricky in South Carolina
Construction class codes are routinely misclassified — operations often span multiple codes, and carriers frequently default to the highest-rated code for an entire payroll instead of properly splitting it. Florida and California have especially strict rules for construction sole proprietors. We do free policy reviews to ensure your codes and split are correct.
