General Liability Insurance for Small Businesses

What general liability insurance covers

General liability insurance (GL), also called commercial general liability (CGL) or business liability insurance, protects your business when someone outside the business says you hurt them or damaged their property. It is the most common business insurance policy in the U.S. and the one clients, landlords and event venues ask for first.

A GL policy usually has three main parts:

• Bodily injury. A customer trips over a cord in your shop, or a client's guest is hurt by your equipment at an event.
• Property damage. You crack a client's countertop, flood a bathroom, or knock over a display while working on site.
• Personal and advertising injury. Someone claims your ad copied their photo, or that you said something false that damaged their reputation.

The policy pays for the settlement or court judgment, and it also pays for your legal defense. Defense costs matter a lot: even a claim with no merit can cost thousands of dollars to fight. Many policies also include a small "medical payments" coverage that pays an injured visitor's minor medical bills quickly, without anyone having to prove fault.

Example: A customer slips on a wet floor at a small bakery and breaks a wrist. The customer's lawyer asks the bakery to pay medical bills and lost wages. The bakery's general liability policy pays for the defense and the settlement, up to the policy limit.

What general liability does not cover

General liability is broad, but it has clear gaps. Knowing them helps you avoid surprises:

• Your employees' injuries. These are covered by workers' compensation, not GL.
• Your own property. Your building, tools, inventory and computers need commercial property or tools and equipment insurance.
• Professional mistakes. If a client says your advice or service cost them money, you need professional liability (E&O). See general liability vs. professional liability.
• Vehicles. Accidents in a business vehicle are covered by commercial auto insurance.
• Cyber incidents. Data breaches and ransomware need cyber liability insurance.
• Intentional or criminal acts, and contractual liabilities you agreed to outside the policy's terms.

Who needs general liability insurance?

Almost every small business that deals with the public needs GL. It is especially important if you:

• Work at client homes or job sites, like a handyman, electrician, painter or cleaning business.
• Have customers visit you, like a hair stylist, barber or restaurant.
• Work events and venues, like a DJ, photographer or caterer.
• Rent commercial space. Most commercial leases require GL.
• Sign client contracts. Many contracts require proof of GL and ask to be named as an additional insured.

Even home-based businesses and sole proprietors often need it, because a homeowners policy usually excludes business activity.

How much does general liability insurance cost?

According to Insureon's 2026 data from 100,000 small-business customers, the median cost of general liability insurance is $45 a month, or $538 a year. The most common choice is a policy with a $1 million per-occurrence limit and a $2 million aggregate limit.

Costs vary a lot by industry. Insureon's 2026 monthly medians for GL include:

The main things that change your price are:

• Industry risk. Physical work at job sites costs more than desk work.
• Location. Claim costs and lawsuit rates differ by state and city.
• Revenue and payroll. Bigger operations usually mean more exposure.
• Claims history. Past claims raise premiums.
• Limits and deductible. Higher limits cost more; a higher deductible can lower the premium.

Limits and deductibles explained

A GL policy has two main limits:

• Per-occurrence limit: the most the policy pays for a single incident (for example $1 million).
• Aggregate limit: the most the policy pays for all claims during the policy period (for example $2 million).

Some policies also list separate limits for personal and advertising injury, damage to rented premises, and medical payments. Many GL policies have no deductible or a low one, but some carriers offer a deductible to reduce the premium. If a contract asks for higher limits than your policy offers, a commercial umbrella policy can add more coverage on top.

Most small-business GL policies are written on an occurrence basis: they cover incidents that happen during the policy period, even if the claim is filed years later.

How to buy general liability insurance

You can buy GL from a licensed independent agent or broker, directly from an insurer, or through an online marketplace. Many small businesses can get coverage the same day. Before you buy, read the exclusions, confirm the limits match your contracts, and ask whether a business owner's policy would cost less if you also need property coverage. After you buy, keep your certificate of insurance handy, because clients and venues will ask for it.

Certificates of insurance and additional insureds

A certificate of insurance (COI) is a one-page summary that proves you have coverage. It lists your insurer, policy number, policy dates and limits. Property managers, general contractors, event venues and corporate clients often ask for a COI before you can start work or set up equipment.

Clients may also ask to be named as an additional insured. This extends your GL coverage to them for claims that arise from your work. For example, if a guest at a venue is hurt by your equipment and sues both you and the venue, the venue can be defended under your policy. Most insurers can add additional insureds quickly, sometimes for a small fee or at no cost.

How to lower your general liability premium

• Bundle coverage. A business owner's policy often costs less than separate GL and property policies.
• Pay annually. Many insurers charge less, or add no installment fees, when you pay the full year up front.
• Choose a deductible if your insurer offers one and you can afford the out-of-pocket cost.
• Manage your risks. Keep work areas clean, use signed contracts, train staff and document safety steps. Fewer claims mean lower renewals.
• Describe your work accurately. Being placed in the right class code avoids overpaying, and avoids a denied claim later.
• Review every year. As your revenue, services and locations change, ask for a fresh quote.
