Quick Answer
South Carolina contractors typically carry general liability, workers’ compensation (generally required for employers that regularly have four or more employees, subject to exceptions), and commercial auto. What you pay is driven by your trade, payroll, annual revenue, project size, and claims history rather than a flat rate.

Average Contractor Insurance Costs in South Carolina
Contractor insurance in South Carolina is not a single policy. It is a package of coverages, and each one carries its own cost. The total depends on what type of contracting work you do, how many employees you have, and the coverage limits your contracts require.
Contractors may need general liability, workers compensation and commercial auto depending on their operations, applicable law and contract requirements. For general and mechanical contractor license group limits, the South Carolina Contractor’s Licensing Board accepts an appropriate surety bond as an alternative to a qualifying financial statement. Below is a breakdown of what each coverage typically costs for SC contractors.
How Much Is Contractor Insurance in South Carolina?
For South Carolina contractors, the better question is not one single price. It is which policies are actually being priced. A quote for general liability only will look very different from a full contractor package that also includes workers compensation, commercial auto, tools and equipment, bonds, and certificate wording.
HVAC, electrical, and concrete contractors are good examples. Each trade can need the same broad insurance categories, but the risk details are different. HVAC work can involve refrigerant, water damage, service vans, and expensive diagnostic tools. Electrical work raises fire, shock, and completed operations concerns. Concrete work often brings heavier equipment, trucks, trailers, forms, subcontractors, and job-site property damage exposure.
If you are comparing contractor insurance cost, line up the quote with the actual work first. Then compare limits, exclusions, certificate wording, subcontractor rules, vehicle use, and whether tools are covered away from your shop.

General liability insurance is the foundation of any contractor insurance package. It covers third-party bodily injury and property damage claims that happen on or because of your job site. Learn more on our Greenville general liability insurance broker page. If a homeowner trips over your tools or you accidentally damage their property during a renovation, your general liability policy pays.
In South Carolina, general liability insurance for contractors generally runs about $96 to $142 per month, with Insureon’s South Carolina policy data putting the general-contractor average at $115 a month. Small businesses statewide average about $46 a month, so trade classification, not geography, is what moves the number. Construction and contracting businesses land on the higher end of that range because of the elevated risk of property damage and bodily injury on job sites. A sole proprietor doing handyman work pays less than a general contracting company with a crew of ten.
Liability insurance requirements vary by license, work and contract. South Carolina law requires at least $100,000 in comprehensive general liability coverage for fire sprinkler contractor licensure. A City of Charleston aquatic weed management contract, for example, specifies $1 million per occurrence and $2 million aggregate; that contract does not establish a citywide rule. Check the applicable licensing board and each contract for required coverage and limits.
An eligible business may be able to package general liability and commercial property in a business owners policy (BOP). Cost depends on the business, property, coverage and deductible; compare matched quotes before deciding whether a package is a better value. See our BOP cost guide for national benchmarks and South Carolina quote factors.
Workers Comp Cost for Contractors in South Carolina
Workers compensation insurance is the most expensive piece of a contractor’s insurance package. Construction trades carry high NCCI class code rates because workplace injuries are more common and more severe than in other industries.
The average workers comp cost for contractors in South Carolina runs around $254 to $336 per month, but your rate depends on the specific type of work. An HVAC technician (class code 5537) pays $3.77 per $100 of payroll. A residential home builder (class code 5645) pays $16.82 per $100 of payroll. That is a massive difference.
South Carolina generally requires workers compensation insurance for businesses that regularly employ four or more employees, subject to exceptions, according to the SC Workers’ Compensation Commission. A general contractor’s responsibility for a subcontractor’s employees depends on the facts and applicable law. Review subcontractor coverage and certificates, while recognizing that a certificate does not amend a policy. See our workers compensation insurance page for a full breakdown of SC requirements.

Surety Bond Costs for SC Contractor Licenses
For a general or mechanical contractor license group, the SC Contractor’s Licensing Board (SCCLB) permits an appropriate surety bond in place of the qualifying financial statement. Bond amounts vary by license type and group; other laws or contracts may require separate bonds.
General Contractor Bonds
The Board lists general contractor bond amounts from $20,000 for Group 1 to $350,000 for Group 5. Mechanical contractor bond amounts range from $7,000 to $300,000 depending on group. The bond must be continuous and maintained as the Board specifies. The cost you pay is a percentage of the bond amount, typically 1-5% for contractors with good credit. A $50,000 bond might cost you $500 to $2,500 per year.
Residential Builder Bonds
South Carolina residential builders must maintain a $15,000 bond. For residential specialty work exceeding $5,000 for an individual property owner, the Residential Builders Commission specifies a $10,000 bond for licensed electrical, HVAC and plumbing contractors and a $5,000 bond for specialty registrants. Check the Commission’s current requirements. General contractor licenses expire in even-numbered years and mechanical contractor licenses expire in odd-numbered years, both by October 31st.
What Affects Bond Cost
Your credit score is the biggest factor in your surety bond premium. Contractors with credit scores above 700 typically pay 1-3% of the bond amount. Lower credit scores push the rate to 5-10%. Your financial statements, industry experience, and claims history also factor in.

How to Lower Your Contractor Insurance Costs
Contractor insurance is a significant business expense, but there are proven ways to bring your costs down without cutting corners on coverage:
Bundle Your Policies
An eligible business may be able to package general liability and commercial property in a BOP. Compare matched quotes and ask each insurer whether adding other policies changes the total price or coverage.
Use an Independent Agent
An independent insurance agency like The Morgano Agency has access to multiple insurance carriers. We shop your contractor insurance package across several companies and find the best combination of coverage and price for your specific trade.
Invest in Safety Training
A documented safety program reduces workplace injuries, lowers your workers comp experience modification rate, and may qualify you for premium credits from your insurance carrier. OSHA’s construction industry resources provide free training materials.
Require COIs from Subcontractors
Always require a certificate of insurance from every subcontractor before they start work. If a sub does not carry their own general liability and workers comp, you may be liable for their claims, which drives up your insurance costs.
