General Liability Insurance: What It Covers, What It Doesn't, and How Much It Costs

If you own a business, someone has told you that you need general liability insurance. Your landlord. A client. A general contractor. Maybe your accountant. They're right. But most business owners carry GL coverage without fully understanding what it does, what it doesn't do, and whether they have the right amount.

This guide covers all of it: the three types of claims GL handles, the exclusions that catch people off guard, what typical policies cost across different industries, and how to make sure your coverage actually matches your risk.

What General Liability Insurance Is

General liability insurance — often called GL or CGL (Commercial General Liability) — protects your business when a third party claims you caused them bodily injury, damaged their property, or harmed them through your advertising. "Third party" means someone who isn't you or your employee: a customer, a vendor, a passerby, a client's property.

GL is reactive. It pays when something goes wrong and someone else holds you responsible. It covers the cost of defending yourself in court, settling the claim, or paying a judgment — up to your policy limits.

Most GL policies follow the ISO (Insurance Services Office) standard form, which means the core structure is consistent across carriers. The differences between policies usually come down to endorsements, exclusions, and pricing — not the fundamental coverage.

The Three Coverage Parts

A standard CGL policy is organized into three coverage categories. Understanding these is the key to knowing what your policy will and won't pay for.

Coverage A: Bodily Injury and Property Damage Liability

This is the core of GL. It covers claims when your business operations cause physical harm to a person or damage to someone else's property.

Bodily injury means physical harm to a person — broken bones, burns, illness, or death. It also covers the consequences of that harm: medical bills, lost income, pain and suffering.

Property damage means physical damage to someone else's tangible property, or the loss of use of that property. If your employee backs a cart into a client's server rack, that's property damage. If your plumbing work causes a leak that makes a tenant's office unusable for a week, the loss of use is also property damage.

Common Coverage A claims:

• A customer slips on a wet floor in your store and breaks a wrist
• Your crew damages a client's hardwood floor while installing cabinets
• A product you sold causes an allergic reaction requiring medical attention
• Your landscaping equipment throws a rock through a homeowner's window

Coverage A also includes something called "products-completed operations" coverage. This extends your GL to cover claims arising from products you've sold or work you've completed — even after you've left the job site or the product has changed hands. If a deck you built last year collapses and injures someone, products-completed operations is what responds.

Coverage B: Personal and Advertising Injury

Coverage B handles a different category of harm — not physical, but reputational and legal. It covers claims of:

• Defamation — libel (written) and slander (spoken) that damages someone's reputation
• False arrest, detention, or imprisonment — relevant for retail businesses that detain suspected shoplifters
• Malicious prosecution
• Wrongful eviction or entry — relevant for property managers
• Copyright infringement in advertising — if your ad campaign uses someone's copyrighted material without permission
• Use of another's advertising idea

Coverage B claims are less common than Coverage A, but they can be expensive. A defamation lawsuit from a competitor or a copyright claim from a photographer whose image you used in a brochure can generate significant legal fees even if the underlying claim is weak.

Coverage C: Medical Payments

Coverage C is the smallest and simplest part of GL. It pays medical expenses for people who are injured on your premises or because of your operations — regardless of who was at fault. No lawsuit required. No determination of liability.

Typical medical payments limits are $5,000 or $10,000 per person. The purpose is goodwill: if someone gets a minor injury at your place of business, you can cover their immediate medical costs without it turning into a claim. A customer trips on a mat in your lobby and needs an X-ray? Medical payments handles it quickly and keeps the relationship intact.

What General Liability Does Not Cover

The exclusions in a GL policy are just as important as the coverages. These are the situations where business owners most often discover a gap:

Your own employees' injuries

If an employee is injured on the job, GL doesn't cover it. That's what workers' compensation insurance is for. GL only covers third-party bodily injury — people who don't work for you.

Professional mistakes and errors

GL covers physical injury and property damage, not economic loss caused by bad advice, negligent work product, or professional errors. If you're a consultant and your recommendation costs a client $200,000, GL won't respond. You need Professional Liability (Errors & Omissions) insurance for that.

Your business vehicles

Any injury or damage involving a vehicle owned, operated, or rented by your business is excluded from GL. That's commercial auto territory. This is a hard exclusion with no workaround.

Intentional acts

Insurance covers accidents, not deliberate harm. If you intentionally damage a competitor's property or assault someone, GL won't cover the resulting claim.

Contractual liability (with exceptions)

GL generally excludes liability you assume under a contract. However, there's a significant exception: the policy does cover liability assumed in an "insured contract," which includes most standard business agreements like leases and construction contracts. This exception is why additional insured endorsements actually work.

Damage to your own property

If a fire destroys your office equipment, GL doesn't pay. You need commercial property insurance. GL only covers damage to property belonging to others.

Pollution

Standard GL policies contain a pollution exclusion. If your business causes environmental contamination — chemical spills, groundwater contamination, asbestos exposure — you'll need a separate environmental or pollution liability policy.

Work you're currently performing

Here's one that surprises contractors: GL typically excludes damage to the specific part of the project you're actively working on. If you're installing tile and you crack the tile, that's not a GL claim — that's a cost-of-doing-business issue. But if your tile work causes water damage to the floor below it, that consequential damage is covered.

Who Needs General Liability Insurance

The short answer: every business. But the level of urgency and the amount of coverage vary significantly.

Businesses that need GL immediately:

• Any business with a physical location where customers or the public can visit
• Contractors and trades — it's required by virtually every GC and project owner
• Businesses that sign contracts with insurance requirements
• Anyone who leases commercial space — your landlord will require it
• Businesses that sell physical products

Businesses where GL is strongly recommended:

• Home-based businesses with client visits or deliveries
• Freelancers and consultants who work on-site at client locations
• E-commerce businesses (product liability still applies)
• Event-based businesses — food vendors, photographers, entertainers

There is no state law requiring GL for most businesses (unlike workers' comp, which is mandatory in most states once you have employees). But the practical reality is that you can't operate without it. Clients won't hire you. Landlords won't lease to you. General contractors won't let you on the job site.

Typical Limits: The $1M/$2M Standard

Most GL policies are sold with a standard limit structure:

• $1,000,000 per occurrence — the maximum the policy will pay for any single claim or incident
• $2,000,000 general aggregate — the maximum the policy will pay for all claims during the policy period (usually one year)
• $1,000,000 products-completed operations aggregate — a separate aggregate for claims arising from your products or completed work
• $1,000,000 personal and advertising injury — per-person or per-organization limit for Coverage B claims
• $100,000 damage to rented premises — also called "fire legal liability," covering damage to space you're renting
• $5,000 medical payments — per-person limit for Coverage C

The $1M/$2M structure is the industry default because most contracts and lease agreements require it. If you carry less than $1M per occurrence, you'll have trouble qualifying for most commercial work.

Some businesses need higher limits — $2M/$4M or even $5M/$10M. Large construction projects, government contracts, and high-value commercial leases sometimes require elevated limits. In many cases, it's more cost-effective to carry standard GL limits and add an umbrella or excess liability policy on top, rather than buying a GL policy with non-standard high limits.

What General Liability Costs

GL premiums vary widely based on your industry, revenue, payroll, location, claims history, and the specific risks of your operations. But here are realistic ranges for small to mid-size businesses buying a standard $1M/$2M policy:

These are annual premiums for small operations — typically under $500K in revenue with no significant claims history. Your actual cost will depend on the specifics of your business. Higher revenue, more employees, riskier operations, or prior claims all push premiums up.

The factors that most affect your GL premium:

• Industry classification code — your NAICS or class code determines your base rate. A roofer pays more than an accountant because the exposure profile is fundamentally different.
• Revenue and payroll — most GL policies are rated on gross revenue or payroll, because these are proxies for the scale of your operations and exposure.
• Claims history — a clean loss history for 3-5 years gets you better rates. Recent claims, even small ones, can increase your premium by 10-30%.
• Location — states with higher litigation costs and more plaintiff-friendly courts (like New York, California, and Florida) have higher GL premiums.
• Subcontractor usage — if you hire subcontractors, carriers want to know whether they carry their own GL and whether you verify their certificates.

How to Get the Right Amount of Coverage

There's no formula that spits out the perfect GL limit for every business. But there are practical guidelines:

Start with contract requirements

Look at the insurance requirements in your leases, client contracts, and any subcontract agreements. The limits specified in those documents are your floor. Most will require $1M/$2M at minimum. If your largest contract requires $2M per occurrence, that's your starting point.

Consider your exposure

A consulting firm that works remotely has different GL exposure than a roofing contractor who puts crews on occupied buildings every day. The question is: what's the realistic worst-case scenario for a single incident? If a catastrophic event at your business could generate a claim exceeding $1M — and in construction, hospitality, or manufacturing, it absolutely could — you need to plan for that.

Use an umbrella for higher limits

If you need $3M, $5M, or $10M in total coverage, the most cost-effective approach is usually a standard $1M/$2M GL policy plus an umbrella or excess liability policy that sits on top. Umbrella policies provide additional limits over your GL, auto, and employers' liability, often at a fraction of what it would cost to increase each underlying policy individually.

Don't buy more than you need

A sole proprietor running a small consulting practice doesn't need $5M in GL. Match your limits to your actual contracts and realistic exposure. Over-insuring wastes money that could be spent elsewhere in the business.

Common Endorsements and Add-Ons

A base GL policy covers the standard risks. Endorsements modify or extend that coverage to match specific situations. Two endorsements come up in virtually every commercial relationship:

Additional Insured

When another party — a client, landlord, general contractor, or project owner — is added as an "additional insured" on your GL policy, your coverage extends to protect them for liability arising from your work or operations. If someone sues both you and the GC because of work your crew performed, your GL policy responds for both of you.

Additional insured status is contractually required in almost every construction agreement, most commercial leases, and many service contracts. It's standard, and your carrier expects to see these requests. The endorsement is usually included at no additional premium or for a nominal charge.

Waiver of Subrogation

Subrogation is the process where your insurance company, after paying a claim, seeks reimbursement from the party that caused the loss. A waiver of subrogation means your insurer agrees not to pursue the party named in the waiver.

Why does this matter? If your work causes damage at a GC's job site and your insurer pays the claim, subrogation would allow your insurer to turn around and sue the GC to recover costs. The waiver prevents that. It's a standard contract requirement that protects the business relationships you depend on.

Primary and Non-Contributory

This endorsement specifies that your GL policy is the first to respond to a claim — before the additional insured's own insurance. Without it, there could be a dispute between carriers about whose policy pays first. Adding primary and non-contributory language eliminates that ambiguity and is required in most construction and commercial contracts.

Other Endorsements Worth Knowing About

• Per-project aggregate — instead of one aggregate for all your work during the year, each project gets its own aggregate limit. Important for contractors working multiple jobs simultaneously.
• Hired and non-owned auto — covers liability for vehicles you don't own but use for business (rental cars, employee personal vehicles used for work errands). This is often added to GL when a standalone auto policy isn't warranted.
• Employee benefits liability — covers claims arising from errors in administering employee benefit programs.

GL as Part of a Broader Program

General liability is the foundation, but it's one piece of a complete business insurance program. Most small businesses need at least GL and workers' comp. Beyond that, common additions include:

• Commercial property — covers your own building, equipment, inventory, and business personal property
• Commercial auto — required if you own or lease business vehicles
• Professional liability (E&O) — covers claims of professional negligence, errors, or omissions
• Cyber liability — covers data breaches, ransomware, and related costs
• Umbrella / excess liability — provides additional limits over your underlying policies

Many carriers offer a Business Owners Policy (BOP) that bundles GL with commercial property and sometimes business interruption coverage at a lower combined premium than buying each separately. For small businesses with straightforward needs, a BOP is often the most cost-effective way to get foundational coverage.

Getting the Right Policy

GL is a commodity product in the sense that most policies use the same ISO form. But the experience of buying and managing it varies enormously depending on your broker.

A good broker will:

• Place your GL with a carrier rated A- or better by AM Best
• Ensure your classification code is accurate (a wrong class code can mean you're overpaying or, worse, that claims could be denied)
• Handle additional insured and waiver of subrogation requests quickly — same day, not next week
• Review your limits annually against your current contracts and exposure
• Bundle your GL with other coverages where it saves you money without sacrificing quality

If your current broker takes three days to issue a certificate, can't explain what your exclusions mean, or hasn't reviewed your coverage since you bought the policy — that's a sign it's time to look elsewhere.
