Commercial general liability (CGL) insurance is defined as a policy that protects businesses from financial losses caused by bodily injury, property damage, personal injury, and advertising injury claims. If you run a small business or work as a contractor, understanding commercial general liability coverage examples is the fastest way to know whether your policy actually protects you. The ISO CG 00 01 form, used by carriers like The Hartford, divides CGL into three parts: Coverage A for bodily injury and property damage, Coverage B for personal and advertising injury, and Coverage C for medical payments. Knowing what each part covers, and what it excludes, helps you avoid costly surprises.
1. common commercial general liability coverage examples
CGL insurance covers bodily injury, property damage, personal and advertising injury, and medical payments. These four categories represent the core of what your policy responds to in a real claim. Here are the most practical scenarios you will encounter:
Bodily Injury on Your Premises or Job Site
A customer slips on a wet floor in your retail store and breaks their wrist. Your CGL policy pays for their medical bills and any legal costs if they sue. The same applies on a job site: if a visitor trips over your equipment and gets hurt, Coverage A responds.
Property Damage During Operations
A plumber accidentally breaks a water pipe while working in a client’s home, flooding the kitchen. The resulting damage to the client’s flooring and cabinets falls under Coverage A. Property damage liability covers both damage caused during active work and damage that surfaces after the job is complete, known as completed operations liability.
Personal and Advertising Injury
Coverage B handles claims that are not physical accidents. Examples include:
- A competitor sues your business for copying their advertising slogan
- A client accuses you of making false statements that damaged their reputation
- Your website accidentally uses a copyrighted photo without permission
These are specified offenses under Coverage B, meaning the policy responds to the offense itself, not just an accident.
Medical Payments for Minor Injuries
Coverage C pays small medical bills for people injured on your property, regardless of fault. This no-fault layer is designed to resolve minor injuries quickly and avoid lawsuits. Limits are typically $5,000–$10,000 per person, and paying small claims fast often prevents a minor incident from turning into expensive litigation.
Defense Costs and Attorney Fees
One of the most valuable features of a CGL policy is that defense costs are covered even if a claim is dismissed. Legal defense alone can cost tens of thousands of dollars, so this protection matters even when you did nothing wrong.
Pro Tip: If a customer suffers a minor injury at your business, report it to your insurer immediately and let the medical payments coverage handle it. Settling small claims early is far cheaper than defending a lawsuit later.
2. typical CGL limits and what they mean
Understanding your policy limits is as important as knowing what is covered. A limit is the maximum dollar amount your insurer will pay for a covered claim.
The most common structure for small businesses is a $1 million per occurrence limit paired with a $2 million general aggregate limit. The per occurrence limit caps what the insurer pays for any single incident. The aggregate limit caps total payouts across all claims in a policy year. Standard small business limits sit at $1 million per occurrence and $2 million aggregate, though high-risk industries like construction often require higher limits by contract.
| Limit Type | Typical Amount | What It Covers |
|---|---|---|
| Per Occurrence | $1,000,000 | Maximum paid for one single claim event |
| General Aggregate | $2,000,000 | Total paid across all claims in a policy year |
| Products/Completed Ops Aggregate | $2,000,000 | Claims from finished work or products sold |
| Medical Payments (per person) | $5,000–$10,000 | No-fault minor injury payments |
| Personal and Advertising Injury | $1,000,000 | Coverage B claims per offense |
Sublimits matter too. Policy sublimits are separate, lower caps within the main policy, and small business owners frequently overlook them. A contractor with a $2 million aggregate could still face a gap if a completed operations claim exceeds the products/completed operations sublimit.
Pro Tip: Pull out your declarations page and check each sublimit individually. The general aggregate number on the front page does not tell the whole story.
3. what CGL does not cover
Knowing what your policy excludes is just as critical as knowing what it covers. CGL is a foundational layer, not a complete solution. Common exclusions include:
- Workers’ compensation claims: If an employee is injured on the job, CGL does not pay. Workers’ comp is a separate, legally required policy in most states.
- Professional errors: A consultant who gives bad advice that costs a client money is not covered under CGL. That requires professional liability insurance, also called errors and omissions (E&O) coverage. See the difference between CGL and professional liability for a full breakdown.
- Auto accidents: If your employee causes an accident while driving a company truck, CGL does not respond. You need commercial auto coverage for that exposure.
- Cyber incidents: A data breach or ransomware attack is not a CGL event. Cyber liability requires its own policy.
- Intentional acts: If you or an employee deliberately damages property or injures someone, the policy will not pay.
- Property in your care: If a customer leaves their equipment with you and it gets damaged, CGL typically excludes it. This is known as the “care, custody, and control” exclusion, and it highlights the difference between property and liability insurance.
The most common confusion is between CGL and professional liability. CGL covers physical accidents and advertising offenses. Professional liability covers mistakes in your professional services or advice. Many small businesses need both.
4. key endorsements that extend your CGL coverage
Endorsements are modifications added to your base CGL policy. For contractors especially, the right endorsements are not optional. They are often required by contract before you can set foot on a job site.
Additional insured endorsements: CG 20 10 vs. CG 20 37
The CG 20 10 endorsement adds a general contractor or property owner as an additional insured for ongoing operations. The CG 20 37 endorsement covers completed operations, meaning claims that arise after your work is finished. Many contracts require both. Using only one creates a timing gap where a post-completion claim leaves the additional insured unprotected.
Selecting the correct endorsement is not a formality. It determines who is protected and when coverage applies.
Primary and noncontributory endorsement
This endorsement makes your CGL policy pay first before the general contractor’s own policy contributes. Without it, both insurers may argue over who pays, delaying claim resolution and creating friction with your client.
Waiver of subrogation
A waiver of subrogation prevents your insurer from suing the additional insured to recover money it paid on a claim. General contractors and property owners routinely require this in their subcontractor agreements.
| Endorsement | Purpose | When It Is Required |
|---|---|---|
| CG 20 10 | Additional insured for ongoing work | Before project starts |
| CG 20 37 | Additional insured for completed work | After project finishes |
| Primary and Noncontributory | Your policy pays before others | Most commercial contracts |
| Waiver of Subrogation | Blocks insurer recovery from additional insured | Standard subcontractor agreements |
Endorsements add cost, but the cost of missing one on a large project is far greater. Review every contract’s insurance requirements before you sign.
Key takeaways
A CGL policy covers bodily injury, property damage, and advertising injury, but only within defined limits and with specific exclusions that require separate policies to fill.
| Point | Details |
|---|---|
| Three coverage parts | Coverage A, B, and C each respond to different claim types under the ISO CG 00 01 form. |
| Standard limits | Most small businesses carry $1 million per occurrence and $2 million aggregate as a baseline. |
| Critical exclusions | Workers’ comp, professional errors, auto accidents, and cyber risks all require separate policies. |
| Endorsements matter | CG 20 10 and CG 20 37 must match the timing of a claim to protect additional insureds properly. |
| Defense costs included | CGL pays attorney fees and defense costs even when a claim is ultimately dismissed. |
What 30 years of CGL claims taught me
After working with hundreds of small business owners and contractors across Massachusetts, the pattern I see most often is not a bad policy. It is a good policy with the wrong limits or missing endorsements.
A contractor will carry a solid $1 million CGL policy, win a large commercial project, and then sign a contract requiring $2 million per occurrence and both CG 20 10 and CG 20 37 endorsements. They do not catch the gap until the general contractor’s certificate of insurance review flags it. At that point, they are scrambling to get their policy updated before the project start date.
The other gap I see constantly is the professional liability confusion. A small IT consultant or marketing agency owner assumes their CGL covers a client’s claim that their work caused financial harm. It does not. CGL covers accidents. Professional liability covers mistakes in your work product. These are two completely different triggers.
My honest advice: read your declarations page every year, not just when you buy the policy. Check your per occurrence limit, your aggregate, your sublimits, and your endorsements. If your business has grown or you have taken on larger contracts, your coverage needs have likely grown too. A quick annual review with your agent costs nothing and can save you everything.
