Business general liability insurance: what it covers and what it does not

The policy organizes coverage into three main insuring agreements:

Bodily injury and property damage. This is the core of a GL policy. A customer slips on a wet floor in your store, a contractor you hired accidentally breaks a client's window, or a product you sold injures someone after they take it home. GL responds to those claims, covering legal defense costs and any judgment or settlement up to your policy limit.

Personal and advertising injury. A competitor claims your ad copied their slogan. A blog post you published about a vendor ends up in a defamation suit. An employee shares a client photo without permission and triggers a privacy claim. These fall under the advertising injury agreement, which sits in the GL policy alongside bodily injury but has its own set of covered offenses.

Medical payments. A narrow, no-fault coverage that pays immediate medical costs when someone is injured on your premises, regardless of whether your business was negligent. It is designed to resolve minor incidents before they escalate into litigation.

Each agreement operates within the policy's per-occurrence limit (the maximum paid for a single incident) and the aggregate limit (the maximum paid across all claims in the policy year). Those two numbers are the main levers when comparing policies.

According to the SBA's Office of Advocacy, there are 36.2 million small businesses in the United States, and 82.3% of them have no employees at all. Even a sole proprietor with no staff carries real GL exposure if they visit client sites, sell physical products, run a business social media account, or rent commercial space.

Three situations make GL non-optional in a practical sense:

• Commercial leases. Most landlords require tenants to carry a minimum GL limit and name the landlord as an additional insured before handing over keys.
• Client contracts. Service businesses, including IT firms, cleaning companies, and marketing agencies, routinely encounter contracts that specify a GL limit as a condition of starting work.
• Licensing and permits. Some state and local licenses, particularly in construction and food service, require proof of GL coverage at application.

Even where no contract demands it, the cost of defending a single bodily injury lawsuit can exceed what most small businesses hold in reserve. The policy buys legal defense from dollar one, which matters as much as the eventual payout.

GL is broad enough to surprise owners when it applies, and narrow enough to surprise them when it does not.

Professional errors. If a consultant gives bad advice, an accountant makes a calculation mistake, or a designer delivers work the client calls unusable, GL will not pay. That exposure belongs to professional liability (errors and omissions) coverage.

Your own property. GL protects third parties. Damage to your own equipment, inventory, or building requires a separate commercial property policy.

Employee injuries on the job. Workers' compensation is a distinct coverage, required in nearly every state for businesses with employees. The National Academy of Social Insurance reports that employers paid an average of $0.98 per $100 of covered payroll in workers' compensation costs in 2023, covering about 150 million workers nationally. That cost is independent of and in addition to any GL premium.

Auto accidents. Vehicles need a commercial auto policy, even for occasional business errands in a personal car. Personal auto policies typically exclude business use.

Intentional acts. No liability policy covers harm your business causes deliberately.

Cyber incidents. A data breach, ransomware attack, or fraudulent wire transfer is not a GL claim. The FBI's Internet Crime Complaint Center recorded $20.877 billion in internet-crime losses across 1,008,597 complaints in 2025, up 26% year over year. Businesses relying on GL alone have no coverage for that category of loss. Standalone cyber liability coverage fills the gap.

No single verified industry-wide average applies across all businesses and risk classes. Underwriters weigh several variables when pricing a GL policy:

• Industry and operations. A landscaper working around client property carries more bodily injury exposure than a software developer who never visits a jobsite. Risk class is the single largest pricing factor.
• Revenue and payroll. Most GL policies rate on gross revenue, payroll, or a combination, because those measure the volume of activity and therefore exposure your business generates each year.
• Location. State-level litigation environments, jury verdicts, and regulatory requirements vary. The same type of business can face meaningfully different rates across state lines.
• Coverage limits. Higher per-occurrence and aggregate limits cost more. Umbrella or excess liability policies extend coverage above the GL limit for an additional premium.
• Claims history. Prior GL claims raise your rate. A clean record is a genuine underwriting advantage.

Many small businesses bundle GL with commercial property coverage in a businessowner's policy (BOP). A BOP is not identical to a standalone GL policy; it packages coverages together, which can reduce administrative overhead, though the bundled limits and exclusions differ by carrier and business class.

On how much to carry: your contractual obligations are the most practical starting point. Leases and client contracts often specify a floor. Your industry's loss history and how much uninsured exposure your cash flow could absorb are the next considerations. A licensed commercial broker, whose credentials you can verify through your state insurance department or the NAIC's consumer resources, can model your specific risk profile and compare admitted carrier options.
