General Liability Insurance Explained: What It Covers, What It Doesn't

General liability insurance is typically the first policy a business buys and the one most commonly required by clients, landlords, and contracts. Despite how common it is, many business owners have only a vague idea of what it actually covers — and a few dangerous misconceptions about what it doesn't.

Here's a complete, plain-English explanation.

What General Liability Insurance Covers

A commercial general liability (CGL) policy protects your business against claims involving three main categories:

Bodily Injury

Coverage kicks in when someone who is not your employee is physically injured due to your business operations or on your business premises.

Scenarios covered:

• A customer slips on a wet floor in your store and breaks their wrist
• A vendor trips over a cable at your office and hits their head
• Your employee drops a piece of equipment that injures a bystander at a job site
• A client visits your home office and is bitten by your dog

When a claim is filed, GL insurance pays:

• Medical expenses for the injured party
• Legal defense costs — attorney fees, expert witnesses, court costs — regardless of whether you win or lose
• Settlements or judgments if you're found liable, up to your policy limit

The legal defense component is critically important. Even a frivolous lawsuit costs $50,000–$150,000 to defend. GL insurance pays those costs even when the claim has no merit.

Property Damage

Coverage applies when your business operations damage someone else's property.

Scenarios covered:

• A contractor accidentally breaks a client's water line during renovation work
• A cleaning company damages an antique table while cleaning a client's home
• A caterer spills red wine on a venue's white carpet
• Your delivery driver clips a parked car

GL insurance pays to repair or replace the damaged property and covers legal defense if the property owner sues.

What's not covered: Damage to your own property. That's what commercial property insurance handles.

Personal and Advertising Injury

This third category covers non-physical harm claims related to your business communications. It includes:

• Libel — written false statements that damage someone's reputation
• Slander — verbal false statements
• Copyright infringement — using someone else's copyrighted material in your advertising without permission
• Trade dress infringement — mimicking a competitor's distinctive look
• Malicious prosecution
• False advertising claims

For small businesses, the most common advertising injury claims are accidental copyright infringement (using a stock photo without proper licensing, for example) and defamatory statements about competitors.

What General Liability Does NOT Cover

GL insurance has important exclusions that business owners frequently misunderstand:

Your employees' injuries. Injuries to your employees are covered by workers' compensation insurance, not GL. If an employee is hurt on the job, GL won't help — you need workers' comp.

Your professional mistakes. If you're a consultant, accountant, or any professional whose advice or work causes a client financial harm, that's a professional liability (E&O) claim, not a GL claim. GL handles physical injury and property damage — not economic harm from professional errors.

Your own property damage. GL covers damage to other people's property. Damage to your own equipment, inventory, or premises requires commercial property insurance.

Vehicle accidents. If a company vehicle is involved in an accident, that's a commercial auto claim. GL may cover some vehicle-related incidents at a job site, but vehicles on public roads need commercial auto coverage.

Intentional acts. GL covers accidents and negligence, not deliberate harm. If an employee intentionally injures someone, GL will not cover the claim.

Pollution and environmental damage. Excluded from standard GL policies. Businesses in industries with pollution exposure need separate environmental liability coverage.

Cyber incidents. Data breaches, ransomware attacks, and related digital incidents require separate cyber liability coverage.

Employment practices. Claims of discrimination, harassment, or wrongful termination require Employment Practices Liability Insurance (EPLI), not GL.

How Much Coverage Do You Actually Need?

GL policies have two key limits:

Per-occurrence limit: The maximum the policy pays for any single incident. Common amounts: $500,000, $1,000,000, $2,000,000.

Aggregate limit: The total the policy pays across all claims in a policy year. Typically 2x the per-occurrence limit ($1M per occurrence / $2M aggregate is a standard policy).

What limit to buy:

For a small service business or sole proprietor: $1M/$2M is the standard starting point and covers the vast majority of scenarios.

For businesses with higher risk (construction, manufacturing, businesses with high foot traffic) or clients who contractually require specific limits: $2M/$4M or higher.

For additional protection: A commercial umbrella policy provides additional limits above your underlying GL policy, typically in $1M increments, at relatively low cost.

The most common mistake: Choosing low limits to save money. The premium difference between $500,000 and $1,000,000 per-occurrence limits is often $100–$300/year. The protection difference in a serious accident is enormous.

What Does GL Insurance Cost?

Annual premiums for general liability insurance vary widely based on:

• Industry — the biggest factor. An office-based consultant pays far less than a roofing contractor.
• Revenue — higher revenue = higher exposure = higher premium
• Number of employees
• Coverage limits
• Claims history
• Location

Rough ranges:

Business Type	Annual GL Premium
Sole proprietor/freelancer	$400–$900
Small retail business	$800–$2,000
Small restaurant	$1,500–$4,000
General contractor	$2,000–$10,000+
Home-based service business	$300–$700
IT/technology company	$700–$2,000

Certificate of Insurance: What It Is and Why You'll Need One

A Certificate of Insurance (COI) is a document that proves you have GL insurance. Landlords, clients, general contractors, and event venues routinely require a COI before doing business with you.

A COI shows:

• Your insurer's name
• Your policy number
• Coverage types and limits
• Policy effective and expiration dates
• The insurer's contact information

You can get a COI from your insurance agent, usually within 24 hours of requesting it. Keep one on file — you'll be asked for it regularly.

Additional insured: Some contracts require you to add the other party as an "additional insured" on your policy. This extends some GL coverage to them for claims arising from your work. Your insurer can add additional insureds with an endorsement, often at no cost for the first few.

Where to Buy General Liability Insurance

Option 1: Business Owner's Policy (BOP). If you also need commercial property insurance (most businesses do), a BOP bundles GL + property at a discounted rate. This is the standard recommendation for most small businesses.

Option 2: Stand-alone GL policy. For businesses that don't need property coverage (home-based consultants, online businesses), a stand-alone GL policy is available.

Option 3: Industry-specific packages. Many industries have specialty insurers that bundle the coverages most relevant to that type of business. A plumber or electrician might get a contractor's package that includes GL, tools/equipment coverage, and commercial auto.

Work with an independent commercial insurance broker — someone who can quote multiple insurers — rather than going directly to a single carrier. Commercial insurance pricing varies significantly, and an experienced broker who knows your industry will find better coverage at better rates than most business owners can find on their own.
