Appliance Repair

South Carolina does not license general appliance repair at the state level. No state license or insurance requirement applies to standalone appliance repair unless the work crosses into a regulated trade (HVAC, electrical, or plumbing) requiring LLR licensure. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI) regardless.

Workers' Compensation Threshold

South Carolina requires workers' compensation coverage once a business regularly employs four or more employees (part-time workers and family members count toward the total); businesses with fewer than 4 employees or less than $3,000 in annual payroll are generally exempt, though coverage for general contractors and subcontractors below the threshold can be determined case-by-case.
