Commercial General Liability: What SC Contractors Get Wrong

Most South Carolina contractors buy a CGL policy, file the certificate, and assume they're covered. Then a claim comes in, the adjuster pulls out the exclusions page, and the contractor finds out their policy had a hole big enough to drive a skid steer through. This guide walks through what a commercial general liability policy actually does, where SC contractors consistently get it wrong, and what to fix before the next job closes.

What a CGL Policy Actually Covers

A standard CGL policy, built on the ISO CGL form structure that most admitted carriers use, contains three core insuring agreements. Understanding what each one does, and what it does not do, is the starting point for every coverage conversation.

Bodily injury and property damage liability is what most contractors think of when they say "general liability." If someone on your jobsite gets hurt and it's your fault, this pays for their medical bills, lost wages, and any judgment against you. If you damage a neighboring property while running excavation work, this responds. The key word is "fault." The policy covers your legal liability, not every loss that happens near your operation.

Personal and advertising injury covers a different set of risks: defamation, false arrest, malicious prosecution, wrongful eviction, and certain copyright and privacy violations in your advertising. For most contractors, this section rarely triggers. But it matters if a dispute with a property owner turns into a defamation allegation or if your marketing materials step on someone else's intellectual property.

Medical payments is a no-fault coverage, typically a low sublimit, that pays for immediate medical treatment for third parties injured on your premises or by your operations, regardless of who is liable. Think of it as a goodwill payment to prevent a small injury from becoming a lawsuit.

For contractors in South Carolina, the bodily injury and property damage section carries the heaviest weight. Construction insurance for active jobsites in a state with year-round building activity means real exposure. A framing crew working a commercial build in Columbia, a concrete contractor pouring footings near a public road in Rock Hill, a roofing company working over an occupied structure in Charleston: all of these scenarios put third parties in proximity to your operations every day. The Bureau of Labor Statistics construction injury data makes clear that the construction sector consistently records some of the highest nonfatal injury rates of any industry. Your CGL is the financial buffer between a serious incident and a judgment that wipes out the business.

The Exclusions That Bite Contractors Most

The exclusions section is where contractors get hurt. Three of them come up repeatedly in disputed construction claims.

The "your work" exclusion says the policy will not pay for damage to the work you performed, if the damage arises from that work. If you install a roof and the roof leaks, the CGL is not going to pay to fix the roof. The policy covers what you do to others, not the cost of fixing your own work product. Contractors consistently assume their CGL is a warranty. It is not.

The faulty workmanship dispute is a close cousin to the above. When a property owner claims your work caused consequential damage, meaning your bad roof caused water damage to the interior structure below it, the coverage question becomes whether the resulting damage qualifies as an "occurrence" under the policy. Some carriers and courts treat consequential property damage as a covered occurrence. Others treat the entire chain of events as a faulty workmanship exclusion. South Carolina case law has addressed this directly, and where your carrier lands on it matters. Do not assume the resulting damage is automatically covered just because you did not intend it.

The contractual liability exclusion catches contractors off guard on commercial projects. When you sign a contract with an indemnification clause, agreeing to hold the property owner or general contractor harmless for losses arising from your work, you have taken on liability that may not exist under common law. The CGL's contractual liability exclusion generally bars coverage for liability you assumed under contract, unless the contract qualifies as an "insured contract" under the policy definition. Most standard construction contracts do qualify. But if your contract is nonstandard, if it shifts liability in unusual ways, or if you signed something without running it by anyone, you may be holding an indemnification obligation your CGL will not back up.

Completed Operations: The Coverage Gap Nobody Talks About

Completed operations coverage is part of the CGL, but it operates on a different trigger than your premises and ongoing operations coverage. Once a job is finished and you walk off the site, your "premises and operations" coverage no longer applies to that job. Completed operations coverage takes over, responding to bodily injury or property damage that occurs after the work is done but results from it.

The exposure window here is longer than most SC contractors realize. South Carolina's statute of repose for construction defect claims runs eight years from substantial completion for most improvements to real property. That means a claim can surface years after the last inspection passed and the final invoice was paid. If your completed operations coverage lapses or was never structured correctly, you are exposed for that entire tail period out of pocket.

The distinction between an "occurrence" and a "professional error" matters here, and South Carolina courts have drawn a line between the two. A sudden, unintended event that causes physical harm, a structural failure, a collapse, an electrical fault that starts a fire, tends to get treated as an occurrence and triggers the CGL's completed operations coverage. A claim that your design or specification was wrong, that your professional judgment caused the defect rather than a discrete physical event, tends to get pushed into professional liability territory, which a standard CGL does not cover.

For contractors doing design-build work, or any contractor who is specifying materials or methods rather than just executing someone else's plans, this distinction is not academic. Construction insurance in South Carolina for design-build operations often requires a separate professional liability endorsement or standalone errors and omissions policy layered on top of the CGL. A contractor in Greenville taking on commercial tenant improvement work who also specifies the HVAC layout is wearing two hats. Make sure both are covered.

Subcontractors on Your Policy vs. Their Own

General contractors in South Carolina commonly ask whether their CGL covers a sub's mistake. The short answer: sometimes, partially, and with consequences.

Most GC policies include coverage for "your work" performed by subcontractors on your behalf. If a sub causes bodily injury or property damage and the GC is named in the claim, the GC's CGL can respond. But the insurer will investigate whether the sub had their own coverage, and if they did, subrogation or contribution between carriers becomes part of the picture. More importantly, if the sub was uninsured, the GC's policy may cover the loss while the carrier simultaneously pursues an audit of the GC's payroll and subcontractor payments to reflect the added exposure. That audit can result in a significant premium adjustment at renewal.

This is why most commercial GCs in South Carolina require subs to carry their own CGL and name the GC as an additional insured. The additional insured requirement means the GC's name is added to the sub's policy, giving the GC direct rights under that policy if a claim arises from the sub's work. It also puts the sub's carrier on the hook first.

The practical problem is that many small subs in South Carolina carry the minimum limits required to get the job, and their coverage may be structured narrowly. If a sub's policy has a classification limitation, meaning it only covers certain types of work, and the sub performed work outside that classification on your jobsite, the sub's carrier can disclaim coverage. That pushes the loss back to the GC. Collecting certificates of insurance from every sub is necessary. It is not sufficient. Verify classification codes and confirm that the work actually being performed matches what the policy covers.

How Coverage Limits Work and Where They Get Thin Fast

A CGL policy has two limit structures that interact constantly: the occurrence limit and the aggregate limit. The occurrence limit is the maximum the policy will pay for any single claim. The aggregate limit is the maximum it will pay across all claims during the policy period.

A $1M/$2M policy, which is a common structure and often the contractual minimum on commercial projects, means one million per occurrence and two million total for the year. On a small residential remodel, those limits may be adequate. On an active commercial construction site in Greenville County or Spartanburg County, they can evaporate faster than expected.

Here is a real scenario: A GC is running a commercial interior build for a Spartanburg business park. Midway through the project, a subcontractor's error causes a fire that damages the partially completed structure and an adjacent occupied tenant space. The injured party in the adjacent suite files a bodily injury claim. The property owner files a property damage claim. The GC faces legal defense costs on top of both. Defense costs erode the occurrence limit in many policy structures, even before a judgment is reached. Two or three active claims in a single policy year, even at moderate severity, can push a $2M aggregate to its ceiling.

Umbrella coverage exists to sit above the CGL and provide excess limits once the primary policy is exhausted. For contractors doing commercial work in Upstate SC, especially near the BMW Spartanburg plant supply chain or any large industrial build, umbrella limits are not optional. They are the difference between the policy absorbing a bad year and the contractor absorbing it personally.

What Certificates of Insurance Don't Actually Guarantee

A certificate of insurance is a snapshot. It shows that a policy existed on the date the certificate was issued. It does not guarantee the policy is still active. It does not show endorsements that restrict coverage. It does not tell you whether the insured has paid their premium since the certificate was printed.

GCs in South Carolina who collect COIs from subs and consider the box checked are taking on more risk than they realize. A sub can let a policy lapse for non-payment and the GC may not find out until a claim is filed and the sub's carrier declines coverage. The additional insured endorsement on the certificate means nothing if the underlying policy has lapsed.

Beyond lapse risk, endorsements matter. A sub's policy might carry an endorsement that excludes coverage for work performed on projects above a certain value, or that restricts coverage to a specific geographic area, or that excludes certain operations entirely. None of that shows up on the face of a COI. To actually vet a sub's coverage, you need a copy of the declarations page, the endorsement schedule, and ideally confirmation directly from the sub's carrier or broker.

The South Carolina Department of Insurance consumer resources can help verify that a carrier is licensed and in good standing in the state. That is a basic check worth running when you are onboarding a sub you have not worked with before. A carrier that is not admitted in South Carolina creates additional complications if you need to pursue a claim.

Getting the Right CGL Structure for Your Operation

When you are reviewing or shopping a CGL policy in South Carolina, the following questions are not optional.

First, are your classification codes accurate? CGL premiums are calculated based on classification codes that describe what work you actually do. A contractor classified as a painting contractor who is also performing structural framing work is misclassified. Misclassification does not just affect your premium. It can affect whether coverage applies to a claim if the work performed falls outside the described operations.

Second, does your completed operations coverage run long enough? Given South Carolina's eight-year repose period for construction defects, a policy that drops completed operations at renewal creates a gap. Make sure your coverage structure accounts for the tail.

Third, what is your subcontractor premium basis? Many CGL policies calculate part of your premium based on the amount you pay to uninsured or underinsured subcontractors. Understand how your carrier treats sub payments and make sure your certificate collection process is solid enough to support your audit position at renewal.

Fourth, do you need a separate professional liability policy? If your work involves any specification, design, or professional judgment beyond pure labor execution, the CGL is not enough.

These are not complicated questions, but they require someone who knows how underwriters think, not just how to fill out a form. Get a coverage review with a team that has worked inside the construction industry, not just around it, and start from what your operation actually does rather than what looks cheapest on a comparison sheet.

Frequently Asked Questions

Does commercial general liability insurance cover faulty workmanship in South Carolina?

Not directly. A standard CGL policy is not a workmanship warranty. The "your work" exclusion means the policy will not pay to repair or redo defective work you performed. Where coverage gets complicated is when your faulty work causes consequential damage to someone else's property. South Carolina courts have addressed whether that resulting damage qualifies as a covered "occurrence," but outcomes vary by carrier language and how the claim is framed. Before assuming you have coverage for downstream damage, review your policy's occurrence definition and talk to a broker who understands how SC courts have ruled.

What is the difference between occurrence and claims-made CGL coverage for South Carolina contractors?

An occurrence policy covers incidents that happen during the policy period, regardless of when the claim is filed. A claims-made policy only covers claims reported while the policy is active. Most SC contractors should be on occurrence-based CGL policies. If you ever carried a claims-made form, you need to understand tail coverage, because a gap between policy periods can leave you exposed to claims filed after the policy lapses. If you are not sure which form you have, pull the declarations page and look for the word "occurrence" or "claims-made" in the coverage form designation.

How much commercial general liability coverage do South Carolina contractors actually need?

The minimum most SC general contractors require from subs is a 1 million per occurrence and 2 million aggregate limit. That floor is not always enough. A single serious bodily injury on a commercial jobsite can push well past 1 million once legal costs, lost wages, and damages are factored in. Contractors working on larger commercial or public projects in South Carolina often face contract requirements of 2 million per occurrence. Review your contract requirements on every job, then stack an umbrella policy on top of your primary CGL limit if your exposure warrants it.
