Does My Small Business Need General Liability Insurance?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

General liability insurance pays for claims that your business hurt someone or damaged their property, plus the legal costs to defend those claims. Federal law doesn’t require it for most businesses, but landlords, clients, and some state licenses often do. The Small Business Administration (SBA) describes it as coverage meant for any business, so most owners should at least get a quote before the first job.

What this means

The SBA says general liability covers money you could lose from bodily injury, property damage, medical expenses, libel, slander, the cost of defending a lawsuit, and settlements or judgments.

Here’s a simple example. A customer trips over a hose at Ridgeline Window Washing’s job site and breaks a wrist. Or a technician knocks over a homeowner’s lamp. Those are the kinds of claims general liability is built for.

General liability usually does not cover:

Injuries to your own employees. That’s workers’ compensation (see 10.3.7 Workers’ Compensation).
Mistakes in your professional advice or work quality. That’s professional liability (see 10.8.2 Professional Liability Insurance).
Accidents while driving for work. That’s commercial auto (see 10.8.4 Commercial Auto Insurance).
Damage to your own building, tools, or stock. That’s property or equipment coverage (see 10.8.5 and 10.8.7).

Many small businesses buy general liability inside a business owner’s policy (BOP). The SBA says a BOP bundles common coverages into one package and can save money. Every policy is different, so the exact list of what’s covered and excluded is in your policy, not on this page.

Why it matters

One claim can be bigger than your bank balance. Legal defense alone can cost more than a year of premiums.
You can lose work without it. Commercial clients, property managers, and general contractors often ask for a certificate of insurance before you start.
Your lease may require it. Many commercial leases name a minimum amount and require the landlord to be listed on the policy.
Some licenses require it. Certain state and city licenses ask for proof of liability coverage. Rules vary by state and trade.
Some ad programs have checked it. Google’s Local Services Ads help page lists general liability for many U.S. categories. Google also says accounts moving into Google Ads in 2026 no longer need insurance reverification, so check the current rules before you count on it (see 20.5 Local Services Ads).
An LLC doesn’t stop every claim. A limited liability company (LLC) can separate business and personal assets, but the business itself can still be sued and lose everything it owns (see 8.6.3 Limited Liability Company).

Who this applies to

Almost every business that meets customers, visits homes or job sites, has a public space, or sells a product. Home-based and online businesses with no customer contact may face lower risk, but should still ask an agent. A homeowner’s policy often doesn’t cover business activity at all. The SBA notes that a home-based business rider can add limited coverage to a homeowner’s policy.

How to do it

List what could go wrong. Write down where you work, who visits you, what you touch in customers’ homes, and what you sell. An agent will ask, and this list makes the quote accurate.
Check what’s required. Look at your lease, client contracts, and your state or city license rules for minimum limits.
Find a licensed agent or broker. Your state insurance department can confirm an agent is licensed. The National Association of Insurance Commissioners (NAIC) website links to every state department.
Get at least two or three quotes. The SBA recommends comparing rates, terms, and benefits from more than one agent.
Compare the same things on each quote: limit per claim, total yearly limit, deductible, exclusions, and whether legal defense costs reduce the limit.
Ask about a BOP if you also need property coverage.
Read the exclusions before you sign. Ask the agent to explain each one in plain words.
Ask how to get a certificate of insurance (COI) and how fast the agent can send one with a client listed as additional insured.
Put the renewal date on your financial calendar (see 10.9.1 Financial Calendar).
Update your website and records. If you say you’re insured, it should be true and current. Record the carrier and policy dates in your Master Business Record (see 5 Master Business Record).

What proof to keep

The full policy and the declarations page
Each certificate of insurance you send, and to whom
Proof of payment for each term
Notes from your agent on any coverage you turned down, and why
Any claim reports and letters from the insurer

Keep these in an insurance folder that at least two trusted people can reach (see 12.2 Shared Files).

Common mistakes

Assuming a homeowner’s or renter’s policy covers business work. It often doesn’t. Ask in writing.
Buying the cheapest policy without reading exclusions. Some trades are excluded on low-cost policies.
Describing your work too narrowly. If you tell the agent “cleaning” but also do pressure washing on roofs, a claim from the roof work may be denied.
Letting the policy lapse. A gap in coverage can leave a claim from that window uncovered.
Saying “fully insured” on your website when you only carry one type of coverage. Say what you have.
Not telling the insurer when you add services or staff. Your policy is priced on what you told them.

When to get help from a pro

A licensed insurance agent or broker should help you choose limits and read exclusions. An attorney can review lease or contract insurance clauses. Questions to ask:

What does this policy exclude for my type of work?
Do legal defense costs come out of my limit or on top of it?
What limits do my lease and my biggest clients require?

Questions people ask

Is general liability insurance required by law? Usually not. The SBA says the required coverages are for businesses with employees, like workers’ compensation, unemployment, and disability insurance, and that states may add more. States, cities, landlords, and clients can require general liability, so check each one.

What does general liability cover? The SBA lists bodily injury, property damage, medical expenses, libel, slander, legal defense, and settlements or judgments. Your policy has the exact terms.

Does it cover mistakes in my work? Usually not. Errors in advice or professional work are covered by professional liability insurance.

What is a certificate of insurance? A one-page summary from your insurer or agent showing your coverage, limits, and dates. Clients ask for it to confirm you’re insured.

Can I buy it with other coverage? Yes. A business owner’s policy bundles general liability with property coverage for many small businesses.

Audit check

Question: Does the business carry current general liability coverage that matches its actual work and meets every lease, license, and client requirement?
Pass looks like: An active policy with the real services listed. Limits that meet or exceed each written requirement. Renewal date on the calendar. Website claims match the coverage.
Fail looks like: No policy. A lapsed policy. Services missing from the policy description. Limits below what the lease or a contract demands. “Fully insured” claims with no proof.
Evidence to collect: Declarations page, current certificate of insurance, lease and contract insurance clauses, and the financial calendar entry for renewal.
