Contractor Insurance Requirements in South Carolina

South Carolina residential licensing is bond-centered rather than built around one published GL minimum for every residential builder. Residential builders are licensed at low project values, and specialty residential contractors are regulated separately. Owners should still require GL, commonly $300,000 to $1,000,000 per occurrence. The citation trail is S.C. Code Ann. §§ 40-59-20, 40-59-220. Treat the quoted number, when one exists, as a licensing floor rather than a safe project limit. A homeowner should request a current Certificate of Insurance showing the exact legal name, policy number, effective dates, occurrence and aggregate limits, products/completed operations, and any additional-insured wording required by the contract or permit office. Where South Carolina does not publish a statewide GL minimum, ProFix describes market ranges only as verification guidance, not as law. Roof, structural, excavation, mold, fire, solar and multi-trade projects should usually be reviewed for umbrella or excess liability because standard GL can contain residential, roofing, pollution, subsidence or subcontractor exclusions.

Workers' compensation is generally required for South Carolina employers with four or more employees. Construction contractors near that threshold should document exemptions carefully, because prime contractors and project owners often require WC even when the statute might not. Cite S.C. Code Ann. §§ 42-1-360, 42-5-20. Coverage is written by private carriers, the assigned-risk plan or approved self-insurance. The certificate should show South Carolina operations and should match the LLR license name. For residential hiring, the key question is not only whether the contractor has a policy, but whether the people entering the home are covered by that policy. Ask whether subcontractors are employees, independent businesses with their own WC, or excluded owners. If the contractor says it is exempt, request the state exemption form or written statutory basis and keep it with the contract file. A GL policy does not pay statutory wage-loss and medical benefits for an injured worker, and an occupational accident policy is not always a substitute for workers' compensation.

Residential builders must file a bond of not less than $15,000 or proof of financial responsibility acceptable to the Commission. Residential specialty contractors have bond duties when the undertaking exceeds $5,000, with common forms using $10,000 for licensed specialty and $5,000 for registered specialty categories. The legal anchor is S.C. Code Ann. § 40-59-220(C)-(D). A license bond is not the same thing as liability insurance: it is a surety promise that may reimburse a claimant only after a covered violation, and the surety normally seeks reimbursement from the contractor. It also is not always a performance bond guaranteeing completion of one homeowner's project. For residential work, ask who the obligee is, the bond amount, the effective dates, cancellation notice, and whether the bond is tied to the state license, a city registration, a right-of-way permit or a specific contract. For public or large commercial work, separate bid, performance and payment bonds can be required even when no residential license bond exists.

South Carolina residential builder licensing starts at a very low residential threshold, while commercial contractor licensing uses different LLR boards and a $5,000 commercial threshold. Do not assume a residential bond or credential covers commercial mechanical or general contracting. For insurance review, residential work should be tested against the homeowner contract, permit office, lender, HOA or condo requirements, and the license classification. Commercial work usually scales faster because leases, architects, public owners and general contractors often require additional insured status, waiver of subrogation, primary-and-noncontributory wording, higher auto limits and umbrella coverage. A contractor who is legal for a small repair may still be underinsured for a structural addition, roof replacement, fire restoration or job involving subcontractors.

Residential specialty contractors, electrical, HVAC and plumbing scopes have specific LLR pathways. Commercial mechanical, electrical and general work may sit with the Contractors' Licensing Board, while asbestos, lead and mold remediation require separate environmental and insurance review. Federal overlays still matter in every state: renovation of pre-1978 painted surfaces can require EPA Renovation, Repair and Painting compliance under 40 C.F.R. Part 745, and asbestos disturbance can trigger OSHA construction asbestos rules at 29 C.F.R. § 1926.1101 plus state notification or licensing. Specialty insurance should match the hazard. Ask about professional liability for design-build advice, pollution or microbial coverage for mold and sewage, rigging/crane coverage for HVAC rooftop units, and hot-work controls for welding or torch-down roofing. A general liability COI with a low premium can be misleading if the trade that caused the loss is excluded.

Search LLR for residential builder, residential specialty and commercial contractor credentials. Ask for bond proof, GL and WC certificates. The South Carolina Department of Insurance can confirm insurer authority, and the bond surety should confirm that the bond is active. Use three documents together: the state or local license record, the COI, and the bond or workers' compensation proof. The license board URL for South Carolina is https://www.llr.sc.gov/, and the insurance regulator URL is https://doi.sc.gov/. Match the business name, DBA, address and license number across all documents; mismatches are the fastest way to spot borrowed insurance or an unlicensed subcontractor. Call the producer listed on the COI, not a phone number supplied only in a text message. For larger residential jobs, require updated certificates before each draw and before final payment. This is an insurance-compliance checklist, not legal advice, and the local permit office can impose stricter conditions than the statewide baseline.
