General liability (GL) insurance is often the first commercial policy a business owner encounters — usually because a landlord, client, or licensing body asks for a certificate of insurance. It is designed to address third-party claims arising from your business operations, not losses to your own property or employees.

This explainer describes how general liability insurance generally works. Policy language varies by carrier and state. Read your own policy and discuss specifics with a licensed insurance professional.

For how GL fits into a broader coverage plan, see what insurance a small business may need. For state-specific business context, see our guides for Virginia, Maryland, and Washington, D.C..

What General Liability Insurance Is

General liability insurance — sometimes called commercial general liability (CGL) — protects your business against certain claims from people outside your organization. If a third party alleges your business caused them harm, GL may pay for legal defense costs and covered damages, up to your policy limits.

GL is a third-party coverage. It is not designed to repair your own equipment, cover your employees' medical bills, or fix your company vehicles.

What General Liability May Cover

Standard GL policies are typically organized into coverage sections. While policy language varies, most address these areas:

Bodily injury and property damage (Coverage A)

This is the core of general liability. It may cover claims that your business operations caused:

  • Bodily injury — A customer slips on a wet floor in your store, or a passerby is injured by falling equipment at a job site
  • Property damage — Your employee damages a client's wall during an installation, or your equipment breaks a neighbor's fence

Defense costs — attorney fees, court costs, and related legal expenses — are often covered in addition to or within your policy limits, depending on policy structure.

Personal and advertising injury (Coverage B)

This section may cover non-physical injury claims such as:

  • Libel, slander, or defamation in advertising or business communications
  • Copyright or trademark infringement in your marketing materials
  • False arrest, wrongful eviction, or invasion of privacy in certain business contexts

Coverage B addresses specific defined offenses listed in the policy. Not every reputational or competitive dispute qualifies.

Medical payments (Coverage C)

Many GL policies include a small medical payments limit to pay minor medical expenses when someone is injured on your premises or by your operations — regardless of fault. This is often used to resolve small claims quickly without admitting liability.

Medical payments limits are typically modest (for example, $5,000 or $10,000) and are separate from your bodily injury liability limits.

How Policy Limits Work

GL policies express limits in two key numbers:

Limit typeWhat it meansExample
Per-occurrenceMaximum for a single claim or related series of events$1,000,000
General aggregateMaximum for all covered claims during the policy term$2,000,000

Some policies also include separate sub-limits for products-completed operations, personal and advertising injury, or damage to premises rented to you.

Example: If your policy is $1M/$2M, the insurer may pay up to $1 million for any single occurrence and up to $2 million total across all occurrences during the policy year.

Who May Need General Liability Insurance

GL is common across many business types:

  • Retail stores and restaurants — Customer foot traffic creates slip-and-fall exposure
  • Contractors and tradespeople — Work at client properties creates property damage and injury risk
  • Professional service firms — Clients visiting your office or you visiting theirs
  • Landlords and property managers — Tenant and visitor injuries on managed properties
  • Event organizers — Injuries to attendees or vendors at events you host
  • Home-based businesses — If clients visit your home or you visit client sites

Even businesses with no employees may carry GL because a contract or lease requires it — not because state law mandates it.

What General Liability Does Not Cover

Understanding exclusions is as important as understanding coverage. GL typically does not cover:

Excluded lossCoverage that may apply instead
Employee work-related injuriesWorkers' compensation
Damage to your own business propertyCommercial property insurance or a BOP
Professional errors, negligence, or bad adviceProfessional liability (E&O)
Auto accidentsCommercial auto insurance
Intentional acts or criminal conductNot insurable
Pollution (unless endorsed)Environmental liability policy
Cyber incidents and data breachesCyber liability insurance
Employee discrimination or wrongful terminationEmployment practices liability (EPLI)

Always read your policy's exclusions section. Endorsements can add or modify coverage.

Is General Liability Required by Law?

There is no federal law requiring every U.S. business to carry general liability insurance. State requirements vary, and most states do not mandate GL for all businesses.

However, GL is often effectively required through:

  • Commercial lease agreements — Landlords commonly require tenants to carry GL and name the landlord as an additional insured
  • Client contracts — Government agencies, corporations, and general contractors frequently require minimum GL limits before you can bid or perform work
  • Event permits — Venues and municipalities may require proof of GL for public events
  • Professional licensing — Some licensing boards require liability coverage as a condition of licensure
  • Industry standards — Trade associations and franchise agreements may set insurance minimums

General Liability vs. a Business Owners Policy

A business owners policy (BOP) bundles general liability with commercial property insurance and may include business interruption coverage. BOPs are designed for eligible small to mid-sized businesses and may cost less than purchasing GL and property coverage separately.

A standalone GL policy may make sense if you already have property coverage elsewhere, lease rather than own your space, or do not qualify for a BOP due to industry classification or revenue size.

Factors That May Affect Your GL Premium

Premiums vary based on:

  • Industry classification — Higher-risk trades (roofing, tree removal) typically pay more than lower-risk office-based businesses
  • Revenue and payroll — Larger operations generally face higher exposure
  • Location — Urban areas and regions with higher litigation costs may affect rates
  • Claims history — Prior GL claims may increase premiums
  • Coverage limits and deductibles — Higher limits cost more; some policies include deductibles for certain claim types
  • Operations scope — Multiple locations, off-site work, and products sold to the public may affect pricing

General Liability in the DMV Region

While GL rules are primarily driven by contracts rather than state statute, businesses operating in our coverage area should note:

  • Virginia — No blanket GL mandate, but workers' comp is required at 3+ employees and commercial auto rules apply to business vehicles
  • Maryland — Contractual GL requirements are common in Baltimore and D.C.-metro government and commercial leasing
  • Washington, D.C. — DISB notes that CGL covers bodily injury, property damage, personal injury, and false advertising claims; commercial auto and professional liability are separate policies

Questions to Ask a Licensed Professional

  • What per-occurrence and aggregate limits do my contracts and lease require?
  • Does my GL policy cover all my business locations and off-site operations?
  • Are products-completed operations covered for my type of work?
  • Do I need additional insured endorsements for landlords or clients?
  • Should I pair GL with professional liability, cyber, or umbrella coverage?
  • Is a BOP more appropriate than standalone GL for my business?

A licensed insurance professional can review your operations, contracts, and existing policies to help you determine whether your GL coverage aligns with your actual risks.

Frequently Asked Questions

What does general liability insurance typically cover?
General liability insurance may cover third-party bodily injury, property damage, and personal and advertising injury claims arising from your business operations. Coverage depends on your specific policy, endorsements, and exclusions.
Is general liability insurance required by law?
Most states do not require general liability insurance for every business. However, clients, landlords, licensing boards, and government contracts frequently require it. Some industries and municipalities have specific mandates.
What is the difference between per-occurrence and aggregate limits?
The per-occurrence limit is the maximum your insurer may pay for a single claim or event. The aggregate limit is the maximum total the insurer may pay for all claims during the policy period. Both limits are stated on your declarations page.
Does general liability cover employee injuries?
No. Employee work-related injuries are generally covered by workers' compensation insurance, not general liability. GL addresses claims from third parties such as customers, vendors, and visitors.
Does general liability cover professional mistakes?
Generally no. Claims arising from professional services, advice, or errors are typically covered by professional liability (errors and omissions) insurance, not standard general liability.
How much general liability insurance do I need?
There is no universal answer. Contractual requirements, industry norms, business size, and risk exposure all play a role. Common limits include $1 million per occurrence / $2 million aggregate, but your needs may differ. A licensed insurance professional can help you evaluate appropriate limits.
