South Carolina Contractors Insurance 

Beyond the state minimums, most contractors need a layered insurance program. A single general liability policy won't protect you from every risk you'll face on a southern job site, where humidity, hurricanes, and high construction volume all increase exposure.

The right mix depends on your trade, your revenue, and whether you own expensive equipment. That said, there are a few coverage types that nearly every SC contractor should carry.

General Liability and Property Damage

General liability (GL) is your first line of defense. It covers third-party bodily injury, property damage, and personal injury claims. If a homeowner trips over your materials and breaks a wrist, or your crew damages a neighbor's fence during demolition, GL responds.

Most SC contractors carry $1 million per occurrence and $2 million aggregate. Premiums for a small residential contractor typically range from $800 to $2,500 per year, while larger commercial operations may pay $5,000 to $15,000 or more. One thing to keep in mind: GL does not cover your own property or tools, and it won't pay for faulty workmanship. Those gaps require separate policies.

South Carolina's insurance market has faced instability in recent years, with some carriers pulling back from new policies in the state. That means shopping early and maintaining clean claims history matters more than ever.

Inland Marine and Tools Coverage

Your tools, equipment, and materials in transit aren't covered by a standard GL or commercial property policy. Inland marine insurance fills that gap. It protects items while they're being transported between job sites, stored in a trailer, or sitting at a temporary location.

For a contractor with $50,000 in tools and equipment, inland marine premiums typically run $500 to $1,500 annually. The policy covers theft, vandalism, fire, and certain weather events. If you've ever had a trailer full of power tools stolen from a job site overnight, you understand why this coverage exists. Deductibles are usually low, often $250 to $500, making it one of the more affordable protections you can add.

Your premium isn't a flat rate pulled from a chart. Insurers calculate it using a mix of business-specific variables, and understanding those variables gives you real control over what you pay.

Business Size and Annual Revenue

Revenue is one of the biggest premium drivers. Insurers view it as a proxy for exposure: more revenue generally means more projects, more employees, and more opportunities for claims. A solo handyman earning $80,000 annually will pay a fraction of what a GC pulling in $3 million pays.

Payroll also matters, especially for workers' comp. The more you pay in wages, the higher your workers' comp premium. Some contractors try to reduce this by classifying workers as 1099 subcontractors, but South Carolina audits these arrangements. If the state determines your "subs" are actually employees, you'll face back premiums, penalties, and potential license issues.

Risk Level of Specific Trades

Not all trades carry equal risk, and your classification code reflects that. Roofing is consistently one of the most expensive trades to insure in South Carolina, with GL premiums two to three times higher than those for painters or finish carpenters. Demolition, excavation, and structural steel work also command higher rates.

Nonresidential construction input prices rose at a 7.1% annualized rate in early 2026, with tariffs on steel and aluminum reaching 50%. Those material cost increases ripple into insurance premiums because higher project values mean higher potential claim payouts. If you're working with expensive materials, your completed operations coverage and builder's risk limits may need to increase accordingly.

Your claims history plays a major role too. A contractor with two liability claims in the past three years will pay significantly more than one with a clean record. Some insurers offer claims-free discounts of 10% to 15%.

Getting the right insurance coverage in South Carolina starts with understanding your license tier, your trade's risk profile, and the specific gaps that a basic GL policy won't fill. Don't buy based on price alone. A cheap policy with exclusions for your most common risk scenarios is worse than no policy at all, because it gives you false confidence.

Get quotes from at least three carriers, including regional insurers who understand southern construction markets. Ask each one about their claims process, audit procedures, and whether they offer contractor-specific endorsements. Read the exclusions section of every policy: that's where the real surprises hide.

Your insurance program should grow with your business. Review your coverage annually, especially if you're adding employees, taking on larger projects, or expanding into new trades. The contractors who avoid catastrophic losses aren't the lucky ones. They're the ones who built the right coverage before they needed it.
