Workers' Compensation Insurance requirements for General Contractors in South Carolina

South Carolina requires employers with four or more employees — including part-time workers and family members — to carry workers' compensation coverage under [SC Code §42-1-360](https://www.scstatehouse.gov/code/t42c001.php). General contractors face additional liability under §42-1-400: a "statutory employer" doctrine that holds the GC responsible for an uninsured subcontractor's injured workers regardless of the GC's own employee count. The 2026 maximum weekly compensation rate is $1,189.94.

Rate setting: NCCI (National Council on Compensation Insurance)

Typical 2026 cost range: $1,800–$13,000 per $100,000 of qualifying payroll. Final premium depends on class-code mix, experience modifier, and underwriting credits.

Classification codes for General Contractors in South Carolina

Code	Description	Base rate (per $100 payroll)
`5403`	Carpentry NOC	,
`5645`	Carpentry — detached one or two family dwellings	,
`5651`	Carpentry — dwellings, three stories or less	,
`5606`	Contractor executive supervisors	,

South Carolina adopts NCCI classification codes through filings approved by the South Carolina Department of Insurance. The [South Carolina Workers' Compensation Commission](https://wcc.sc.gov/) administers claims and compliance. NCCI administers South Carolina's residual market with Travelers as the assigned risk carrier. Form 2 (Employer's Notice of Being Subject to the Act) must be posted publicly in every place of business once coverage is in effect.

South Carolina's four-employee threshold and statutory employer doctrine

South Carolina's Workers' Compensation Act creates a moderate threshold for coverage: SC Code §42-1-360 requires coverage at four or more employees — full-time, part-time, or family members all count toward the threshold. This is more permissive than 1-employee states (FL construction, IL, NJ, AZ, MA, etc.) but stricter than 5-employee states (TN general, AL general, MO general).

For general contractors, the four-employee threshold does not provide reliable protection. The statutory employer doctrine under SC Code §42-1-400 holds general contractors liable for workers' comp benefits to employees of subcontractors who lack their own coverage, regardless of the GC's direct employee count. A GC with three employees and four uninsured subcontractor employees is a statutory employer to those subcontractor employees.

The practical compliance posture: South Carolina GCs require certificates of insurance from every subcontractor before allowing them on the job site, even when the GC's direct employee count is below four.

Form 2 posting requirement

South Carolina requires employers with active workers' comp coverage to post Form 2 — Employer's Notice of Being Subject to the Act publicly in every place of business. The notice informs employees that the employer carries coverage and explains workers' rights under the Act.

Form 2 must be obtained from the SC Workers' Compensation Commission website and posted in a conspicuous location accessible to employees. Failure to post Form 2 is a separate violation from non-coverage and can produce its own civil penalties.

Class codes for South Carolina general contractors

South Carolina uses NCCI classification codes. General contractors typically have:

Code 5606 — Contractor executive supervisors
Code 5403 — Carpentry NOC
Code 5645 — Carpentry, detached one or two family dwellings
Code 5651 — Carpentry, dwellings three stories or less
Code 8810 — Clerical office (segregated payroll only)

Classification accuracy is verified at audit. The maximum weekly compensation rate for accidents occurring on or after January 1, 2026 is $1,189.94 per week — placing South Carolina in the upper-middle tier nationally for benefit levels despite moderate premium pricing.

SC Contractor's Licensing Board

The South Carolina Contractor's Licensing Board (CLB) operates under the Department of Labor, Licensing and Regulation. License classifications:

Group I — Building (residential and commercial general construction)
Group II — Highway (road and infrastructure construction)
Group III — Public Utilities
Group IV — Specialty trades

Each group has its own minimum net worth and financial responsibility requirements. License applicants must demonstrate workers' comp coverage at issuance and continuously thereafter. Lapsed coverage triggers Workers' Compensation Commission notification and potential CLB license suspension.

The "clincher" settlement system

South Carolina offers two distinct settlement structures:

Agreement and Final Release (clincher) settlements — Full and final lump-sum or structured settlement releasing all employer/carrier liability. The settlement must be approved by a workers' comp commissioner. Once approved, the worker cannot reopen the claim regardless of medical deterioration.
Form 17 settlements — Partial settlements where the employer retains some ongoing liability for medical care but resolves indemnity benefits.

Clincher settlements are popular with employers because they provide certainty — no future claim reopenings. For GCs with significant claim exposure, clincher settlements can be a strategic tool to clean up open claims before EMR calculation periods.

Independent contractor classification

South Carolina uses common-law right-to-control tests for independent contractor status. The Workers' Compensation Commission examines: who controls work methods, who provides equipment, payment structure, firing rights, and continuity of relationship.

Misclassification investigations result in retroactive premium chargebacks. For construction-specific cases, the SC Code §42-1-400 statutory employer doctrine produces additional exposure: even properly-classified independent contractors can become statutory employees of the GC if the contractor lacks their own workers' comp coverage.

Penalty exposure

South Carolina's penalty structure for non-coverage:

$100 per day per employee without coverage
Misdemeanor charges with potential imprisonment up to 30 days for willful violations
Stop-work orders halting business operations
Personal liability for all medical and indemnity costs of uninsured-period injuries
Asset seizure — under SC law, the state can take business assets to cover the cost of uninsured claims

The $3,000 minimum payroll exemption may apply to very small operations, but most ongoing GC businesses exceed this threshold quickly.

What South Carolina GCs actually pay

2026 South Carolina general contractor premiums typically range from $1,800 to $13,000 per $100,000 of qualifying payroll, depending on class-code mix, geographic territory (Charleston metro and coastal counties trend higher), and experience modifier. South Carolina's overall workers' comp cost environment is moderate — neither among the highest-cost nor lowest-cost states.

South Carolina operates a competitive private market with no state insurance fund. NCCI administers the residual market with Travelers as the assigned risk carrier.

The Hartford and Travelers both have substantial South Carolina construction books. For Charleston metro and coastal accounts, both carriers compete actively. For smaller GCs, Next Insurance offers competitive direct-digital pricing.

Bottom line for South Carolina general contractors

South Carolina's four-employee threshold provides modest relief for very small operations but is effectively eliminated by the §42-1-400 statutory employer doctrine for any GC who hires subcontractors. The clincher settlement system provides strategic claim-management tools for closing exposure. The leverageable variables are: rigorous subcontractor COI verification, classification accuracy across the mixed code base, EMR management through return-to-work programs, and active competitive shopping at every renewal.
