General liability insurance: what it covers, who needs it and cost

General liability is the policy nearly every business ends up buying — not because the law demands it, but because the businesses you deal with do. Landlords require it before handing over keys. Customers require it in contracts. Event venues, marketplaces, and general contractors require it before you set foot on site. This guide explains what general liability insurance actually covers, the important things it doesn't, who needs it and when, and how most companies end up buying it. If your question is specifically about price, we've broken that out into its own guide: how much is general liability insurance.

The short answer (as of July 2026)

General liability insurance covers claims that your business injured someone or damaged their property — a visitor slipping in your office, an employee damaging a client's equipment — plus certain advertising and personal-injury claims. It's usually the first and least expensive policy a business buys, at a median of about $45 a month (Insureon, 2025), and it's required by most commercial leases and many customer contracts.

What General Liability Insurance Covers

A general liability (GL) policy responds to three broad categories of third-party claims:

  • Bodily injury. Someone who isn't your employee gets hurt because of your business — a visitor trips over a cable in your office, a customer is injured at your event booth. The policy pays their medical costs and your legal defense, and settlements or judgments up to the limit.
  • Property damage. Your business damages property that belongs to someone else — your team cracks a client's conference-room screen during an install, a leak from your suite damages the office below.
  • Personal and advertising injury. A defined set of non-physical harms, typically including libel, slander, and certain advertising-related claims like using someone's likeness without permission.

Crucially, GL pays your defense costs for covered claims — usually the largest expense even when a claim is weak — in addition to any settlement.

What General Liability Does NOT Cover

The name misleads people: "general" liability is actually quite specific. It excludes most of the exposures that dominate modern service and technology businesses:

  • Professional mistakes. Bad advice, a failed deliverable, software that doesn't work — those are professional liability claims, covered by E&O or tech E&O, not GL.
  • Data breaches and cyber incidents. Breach response, ransomware, and privacy claims belong to cyber insurance.
  • Your own property. GL covers damage you cause to others' property. Your laptops, equipment, and office contents need commercial property coverage — usually bought together with GL in a Business Owner's Policy.
  • Employee injuries. Workplace injuries are the province of workers' compensation, which state law generally requires once you have employees.
  • Management decisions. Claims against your directors and officers are covered by D&O insurance.

A useful mental model: GL covers the physical-world accidents any business could have. Everything specific to what your business does needs its own policy.

Who Needs General Liability — and Who Requires It

No state generally requires a business to carry GL the way workers' comp or auto liability is mandated. In practice, the requirement comes from contracts:

  • Commercial leases almost universally require GL — $1M per occurrence and $2M aggregate are the most common limits — with the landlord named as additional insured.
  • Customer contracts and MSAs routinely include a GL requirement alongside professional liability and cyber, even for software vendors who will never set foot on the customer's premises.
  • Vendor onboarding, venues, and partnerships. Trade shows, co-working operators, retailers, and general contractors typically collect a certificate of insurance evidencing GL before you participate.

Even without a contractual trigger, any business with an office, in-person meetings, events, or physical operations carries the underlying exposure. Because the coverage is inexpensive, the risk-for-dollar case is straightforward.

Limits, Structure, and the BOP Question

The standard starting structure is $1M per occurrence / $2M aggregate — the per-claim cap and the policy-year cap, respectively. Higher limits are typically achieved with an umbrella policy layered above GL rather than a bigger primary policy.

Most small businesses don't actually buy GL standalone. If you have any office, equipment, or inventory, a Business Owner's Policy bundles GL with commercial property at a median of about $83 a month (Insureon, 2025) — usually cheaper than the two policies separately. Standalone GL makes sense when you have no property to insure or when a specialized program covers property elsewhere.

Startups have one extra wrinkle: enterprise customers and landlords each impose their own requirements, and the wording (additional insured status, waiver of subrogation, primary and non-contributory language) matters as much as the limits. Our general liability for startups guide covers those contract mechanics in depth.

Frequently asked questions

Is general liability insurance required by law?

Generally no — unlike workers' compensation or auto liability, no state broadly mandates GL. The requirement comes from leases, customer contracts, and vendor agreements, which is why nearly every operating business ends up carrying it anyway.

How much general liability coverage do I need?

$1M per occurrence / $2M aggregate is the standard starting point and satisfies most leases and contracts. Larger customers or higher-risk operations may require more, usually added via an umbrella policy.

Does general liability cover my work or product failing?

No. Claims that your service, advice, or software failed a customer are professional liability (E&O) claims. GL covers third-party bodily injury, property damage, and certain advertising injuries — not professional mistakes.

What's the difference between general liability and a BOP?

A BOP contains general liability plus commercial property coverage (and usually business interruption) in one bundled policy. If you have equipment or an office, the bundle is typically the better value at a median of about $83/month versus $45/month for GL alone (Insureon, 2025).
