Legal & IP Basics
General liability insurance covers third-party bodily injury, property damage, and advertising claims. See what it leaves out and which policy covers each gap.

What does general liability insurance cover? Three things: injuries to a customer on your property, damage to someone else's belongings, and claims like libel or a copied slogan under personal and advertising injury. It does not reach your own equipment, an employee's on-the-job injury, a mistake in your professional advice, or a crash involving a company vehicle.
Each of those exclusions has its own policy, and assuming general liability already covers them is how founders end up underinsured for the exact risk they thought was handled.
General liability, sometimes called commercial general liability or CGL, is built around three coverage areas that show up in nearly every policy. You'll often see it sold as a stand-alone policy, folded into a business owner's policy, or bundled into a commercial package, but the three coverage areas underneath stay the same.
The first is bodily injury and property damage liability, which pays for medical bills, legal defense, and damages if your business is found responsible for hurting someone or damaging what belongs to them. A customer trips over a loose floor tile in your studio and needs stitches. A painting crew leaves a hose running on a job site and floods the client's basement. Both are the kind of everyday accident this coverage exists for.
The second is personal and advertising injury, which insurers usually treat as its own line inside the policy. It covers claims like libel, slander, false arrest, or using someone else's advertising idea or copyrighted material without permission. A competitor claims your new campaign lifted their tagline, or a review you posted about a supplier crosses into defamation. Neither involves anyone getting physically hurt, but both are the kind of dispute general liability is built to answer.
The third piece, medical payments, is smaller and works differently. It pays a visitor's minor medical bills on a no-fault basis, without anyone having to prove your business did something wrong. That lets small claims get settled quickly instead of turning into a dispute over who was at fault.
General liability protects against third-party claims. It was never built to cover your own losses, your team, or your vehicles, and that distinction produces four common gaps.
| What's excluded | Which policy covers it |
|---|---|
| Your own equipment or property | Commercial property insurance |
| An employee hurt on the job | Workers' compensation |
| A mistake in your professional advice or service | Professional liability (errors and omissions) |
| An accident involving a company vehicle | Commercial auto insurance |
None of these are optional add-ons bolted onto a general liability policy. They are separate products, often sold by the same carrier and sometimes bundled into a business owner's policy alongside general liability itself. Some are not optional at all. Most states require an employer to carry workers' compensation once it has employees, the thresholds and exceptions are set state by state, and individual states set their own requirements for the rest of the list.
Every policy caps what it pays in two ways. A per-occurrence limit sets the maximum for any single claim. An aggregate limit sets the maximum the policy will pay across every claim combined during the policy period, which is usually one year.
Once you hit the aggregate limit, the policy has nothing left for additional claims until it renews. That is why the aggregate limit matters more as your business grows. More contracts and more customer contact mean more chances for a claim, and a policy that looked generous at launch can start to look thin. Founders in higher-exposure trades sometimes layer an umbrella policy on top once revenue justifies the cost, which extends coverage past the underlying aggregate limit.
Bodily injury and property damage claims usually draw from the same aggregate limit as personal and advertising injury claims, so a bad string of either type eats into the same pool. Medical payments typically carry their own separate, smaller limit, since the coverage settles minor claims without a lawsuit.
Almost any business that deals with customers or vendors, or that works out of a physical location, benefits from it, but two situations make it close to mandatory.
The first is contracts. Client agreements, vendor contracts, and commercial leases routinely require proof of general liability before you can sign, usually in the form of a certificate of insurance your carrier generates once you're covered. The same instinct that makes you check whether you need a business license applies here: confirm what a contract requires before you're the one caught without it.
The second is physical access to someone else's property. If you run a home services business and work inside a client's house, storefront, or office, you're creating exactly the bodily injury and property damage exposure general liability is built for. Most clients will ask to see proof of coverage before they let you start the job. Consultants who meet clients on-site, contractors, event vendors, and retailers all fall into the same bracket.
Landlords and larger clients often go a step further and ask to be named as an additional insured on your policy. That status extends part of your coverage to protect them if a claim traces back to your work on their property, and it typically costs little to add. It is often what they are waiting on before a lease or contract moves forward.
You can buy general liability through a licensed insurance agent or broker, directly from a carrier, or through an online commercial insurance marketplace that compares quotes across carriers. Each path asks for the same basics before it can quote you:
Have those ready before your first call. That keeps a quote from turning into a multi-day back-and-forth.
Cost varies by all of those factors plus the coverage limits you choose, so treat any number you see quoted online as a starting point for a conversation rather than a fixed price. A licensed agent or broker can walk you through what your specific business needs. Your state insurance department lists licensed agents by state, and it is also where a complaint goes if a policy does not hold up the way it was sold.
General liability is one line item in the broader stack of business laws founders have to track, alongside contracts, structure, and licensing. Get the core policy in place before you sign your first client contract or commercial lease. Add the other pieces as your business actually takes on those risks: workers' comp once you hire, professional liability if you give advice, commercial auto if you put a vehicle on the road.
