General Liability Insurance for Small Businesses: What It Covers and What It Doesn't
A plain-English guide to commercial general liability (CGL) insurance: the three core coverages, common exclusions, how limits work, and who needs it.
If you run a small business, general liability insurance is usually the first policy anyone asks you about. Landlords want it in the lease, clients want a certificate before you start a job, and event organizers often won't let you set up without it. But many owners buy it without knowing exactly what it does — and, just as important, what it doesn't do.
This guide explains commercial general liability (often shortened to CGL or GL) in plain English so you can have a more informed conversation with a licensed agent.
What general liability insurance is
General liability is a third-party policy. It responds when someone outside your business — a customer, a visitor, a client, a member of the public — claims your business operations harmed them. Most standard policies are built on a widely used industry form, which is why the core structure looks similar from insurer to insurer, even though the details, endorsements and exclusions differ.
When a covered claim is made, the policy typically does two things: it pays for your legal defense, and it pays damages you become legally obligated to pay, up to the policy limits. For many small businesses, the defense part is just as valuable as the payout, because even a claim without merit can be expensive to fight.
The three core coverages
1. Bodily injury and property damage
This is the part most people think of. A customer slips on a wet floor in your shop. A contractor accidentally cracks a client's countertop. A delivery from your business damages a neighbor's fence. If someone claims your business caused physical injury to a person or physical damage to property that isn't yours, this coverage is designed to respond.
2. Personal and advertising injury
This covers certain non-physical harms, such as claims of libel or slander, and some advertising-related claims like using another party's advertising idea in your ads. The exact list of covered offenses is defined in the policy, so it's worth reading if you do a lot of marketing.
3. Medical payments
Many policies include a small amount of "med pay" that can cover minor medical expenses for someone injured on your premises or by your operations, often regardless of fault. It's meant to handle small incidents quickly before they turn into lawsuits.
What general liability usually does not cover
Understanding the gaps is where owners save themselves from unpleasant surprises. Common exclusions and limitations include:
- Injuries to your own employees. These are generally handled by workers' compensation.
- Your own property. Your equipment, inventory and building need property coverage, often bundled in a business owner's policy (BOP).
- Vehicles. Accidents involving autos are typically excluded and need commercial auto insurance.
- Professional mistakes. If a client says your advice or service caused them a financial loss, that is usually a professional liability issue.
- Your own faulty work. Many policies exclude the cost to redo or repair your own defective work, even if they may cover resulting damage to other property.
- Property in your care, custody or control. If you're working on or holding a customer's property, damage to that property may be excluded. Groomers, cleaners and repair businesses should ask about this specifically.
- Intentional acts, pollution, and contractual liability beyond what the policy allows.
Exclusions vary between insurers and can be changed by endorsements. The list above describes common patterns, not any specific policy. Read the exclusions section of any policy you're considering.
How limits work
General liability policies normally show at least two key numbers:
| Limit | What it means |
|---|---|
| Each occurrence | The most the policy will pay for a single incident. |
| General aggregate | The most the policy will pay for all covered claims during the policy period. |
| Products-completed operations aggregate | A separate cap for claims arising from products you sold or work you completed. |
A common structure for small businesses is a $1 million per-occurrence limit with a $2 million aggregate, partly because many leases and contracts ask for exactly that. Whether it's right for you depends on your risks and contracts. If a client requires higher limits, an umbrella policy is often a cost-effective way to add extra protection on top.
Who needs general liability insurance?
Almost any business that interacts with the public, visits client sites, or rents commercial space should look at it. It's especially relevant if you:
- Have customers or clients visit your location.
- Work inside other people's homes or businesses.
- Sell physical products that could injure someone.
- Sign leases or contracts that require proof of insurance.
- Attend markets, fairs or events where organizers require coverage.
What affects the price
Insurers price general liability based on how risky your operations look. The main factors are usually your type of work, your revenue or payroll, your location, your claims history, how many employees you have, and the limits and deductible you choose. A home-based consultant and a roofing contractor can both buy "general liability," but their premiums will be very different because the likelihood of injury and property damage is very different.
Because pricing depends so heavily on these factors, the best way to understand your cost is to request quotes for your specific business, ideally comparing more than one option.
Questions to ask before you buy
- Does the policy cover work I do at client sites, not just at my own location?
- Are there exclusions specific to my industry?
- Is damage to customer property in my care covered, or do I need an add-on?
- Can I add clients as "additional insureds" if a contract requires it, and is there a fee?
- Does it cover subcontractors I hire, or do they need their own policies?
- Is it an occurrence policy or a claims-made policy?
Frequently asked questions
Is general liability insurance required by law?
Generally no single federal law requires it, but landlords, clients, event organizers and some licensing authorities commonly require proof of it before they will work with you.
Does general liability cover injuries to my employees?
No. Employee work injuries are normally handled by workers' compensation insurance, which general liability policies exclude.
What is the difference between general liability and professional liability?
General liability covers physical harms such as injuries and property damage. Professional liability (errors and omissions) covers financial losses caused by mistakes in your professional services or advice.
