South Carolina Contractor Insurance

General Liability: Protection Against Third-Party Claims

General liability (GL) insurance is the policy most people picture when they hear "contractor insurance." It covers bodily injury and property damage claims made by third parties: clients, bystanders, neighbors, anyone who isn't on your payroll.

A typical example: you're installing a fence and accidentally damage your client's irrigation system. GL pays for the repair. Or a visitor trips over your materials on a job site and breaks a wrist. GL covers their medical bills and your legal defense if they sue.

In South Carolina, GL premiums for contractors generally start around $500 to $2,000 per year depending on your trade, revenue, and claims history. Higher-risk trades like roofing or demolition pay significantly more than painters or finish carpenters. Most commercial clients and general contractors will require you to carry at least $1 million per occurrence before they'll let you on site.

Tools and Equipment Coverage (Inland Marine)

Your standard business property policy probably doesn't cover tools, materials, and equipment while they're in transit or stored at a job site. That's where inland marine insurance comes in, and it's one of the most overlooked policies among smaller contractors.

Think about what you haul to every job: power tools, generators, scaffolding, laser levels, compressors. If someone breaks into your trailer overnight or a fire destroys your equipment on site, inland marine pays to replace it. The cost is surprisingly affordable: inland marine policies often run between $300 and $1,500 annually based on the total value of your covered equipment. For most contractors, that's a fraction of what it would cost to replace even a few stolen power tools out of pocket.

Commercial Auto Insurance for Work Vehicles

South Carolina requires minimum auto liability limits of 25/50/25, meaning $25,000 per person for bodily injury, $50,000 per accident, and $25,000 for property damage. But here's the catch: your personal auto policy almost certainly excludes vehicles used primarily for business purposes.

If you're hauling materials in a truck registered to your LLC, or if employees drive company vehicles between job sites, you need a commercial auto policy. Premiums depend on the number of vehicles, driver records, and how far your crews travel. A single work truck might cost $1,200 to $2,500 per year to insure commercially. Fleets of five or more vehicles can negotiate better per-unit rates, especially through an independent agency like CSP Insurance Services that can compare quotes across multiple carriers.

Workers' Compensation Laws for Small Businesses

South Carolina requires workers' compensation coverage for any business with four or more employees. That threshold is lower than some neighboring states, and it catches a lot of small contractors off guard. If you have three full-time crew members and hire a temporary laborer for a weekend project, you've just crossed the line.

As of January 1, 2026, the South Carolina Workers' Compensation Commission set the maximum weekly compensation rate at $1,189. That's the cap on what an injured worker can receive per week in benefits. Your premium is calculated based on your total payroll and the classification codes assigned to your workers' job duties.

Businesses that fail to carry required workers' comp face fines, stop-work orders, and personal liability for injury costs. South Carolina's enforcement has gotten more aggressive in recent years, with random audits and investigations targeting industries like construction where non-compliance is common.

Surety Bonds vs. Insurance: Knowing the Difference

This is one of the most common points of confusion. A surety bond is not insurance. Insurance protects you. A bond protects the public from you.

When you purchase a contractor license bond, you're essentially guaranteeing that you'll follow state regulations and complete work according to contract terms. If you don't, the bond company pays the claim, then comes after you for reimbursement. South Carolina's Contractors' Licensing Board requires surety bonds for residential builders and specialty contractors. The bond amounts vary by license type, and bond requirements are outlined in the state's licensing documents. Premiums typically run 1% to 5% of the bond face value, so a $15,000 bond might cost you $150 to $750 per year depending on your credit score and financial history.

Licensing Requirements and Proof of Coverage

South Carolina's Contractors' Licensing Board, housed under the Department of Labor, Licensing and Regulation, handles contractor licensing. To obtain or renew most licenses, you'll need to provide proof of general liability insurance and a surety bond. The specific requirements depend on your license classification.

Renewals happen on a set schedule, and the LLR website maintains current renewal information including deadlines and required documentation. Letting your insurance lapse, even briefly, can trigger license suspension. One thing to keep in mind: your insurance carrier is often required to notify the state directly if your policy is canceled, so there's no way to quietly let coverage slide.

Comparison Chart: Policy Requirements by Contractor Type

Roofers and general contractors consistently pay the highest premiums because their work involves greater injury risk and higher property damage potential. A general contractor in South Carolina might pay two to three times more for GL coverage than a finish carpenter doing similar annual revenue.

How Payroll and Revenue Affect Costs

Workers' comp premiums are directly tied to your payroll. The more you pay employees, the more your coverage costs, because higher payroll generally means more workers exposed to injury risk. GL premiums often factor in annual revenue as a proxy for how much work you're doing and how many third parties you're interacting with.

Here's a practical example: a painting contractor in Columbia with $200,000 in annual revenue and two employees might pay $1,800 per year for GL and $2,500 for workers' comp. Scale that same business to $600,000 in revenue with six employees, and you're looking at roughly double those figures. An independent agency can help you audit your classification codes to make sure you're not overpaying because workers are slotted into the wrong risk category.

Risk Levels for Specialized Trades

South Carolina's coastal exposure adds a layer of risk that inland states don't deal with. Contractors working in hurricane-prone areas like Myrtle Beach or Charleston may face higher premiums, especially for property-related coverages. Wind and hail damage claims spike after storm season, and insurers price that into your policy.

Specialized trades like demolition, structural steel, and tree removal sit at the top of the risk scale. If you're in one of these fields, expect to pay premium rates that reflect the danger. On the other hand, low-risk trades like interior painting, flooring installation, and cabinetry enjoy some of the lowest rates available.

FAQ: Do I need insurance if I'm a one-person LLC?

South Carolina doesn't require a sole proprietor or single-member LLC to carry workers' comp. But general liability is still required for most licensed contractors, and many clients won't hire you without it. Even if it's not legally mandated for your specific situation, going without GL is a financial gamble most solo contractors can't afford to lose.

FAQ: How much does a basic policy cost in South Carolina?

A basic GL policy for a low-risk trade starts around $500 to $800 per year. Add commercial auto ($1,200+), inland marine ($300+), and a surety bond ($150+), and most solo contractors are looking at $2,000 to $4,000 annually for a solid coverage package. Higher-risk trades or larger crews can easily reach $10,000 or more.

FAQ: Does my personal auto policy cover my work truck?

Almost certainly not if the vehicle is used regularly for business. Most personal auto policies exclude commercial use, and if you file a claim after an accident on the way to a job site, your insurer may deny it. Get a commercial auto policy or at least a business-use endorsement on your personal policy.

FAQ: What happens if I don't have Workers' Comp?

If you're required to carry it (four or more employees) and don't, you face fines up to $1,000 per day of non-compliance, a stop-work order that shuts down your job sites, and personal liability for any employee injuries. The SC Workers' Compensation Commission does not treat this lightly.

FAQ: Can I get a certificate of insurance the same day?

Yes, in most cases. Many agencies, including CSP Insurance Services, can bind coverage and issue a certificate of insurance within the same business day. If a general contractor needs proof of your coverage before you start a job tomorrow morning, that's usually doable with a quick phone call.
