General Liability Insurance for Contractors: Coverage, Cost & Best Providers

Quick answer: General liability insurance pays when your work injures someone else or damages someone else's property, including legal defense costs. Most contractors buy a policy with a $1 million per-occurrence / $2 million aggregate limit. The median contractor pays about $89 per month ($1,069 per year), but your trade changes the price a lot: electricians average around $61/month, while roofers average about $317/month.

If you run a construction or trade business, general liability insurance is usually the first policy you need. Clients ask for it before they sign a contract, general contractors won't let subcontractors on site without it, and many cities and states want proof of it before they issue a license or permit.

This guide explains what the policy covers, what it doesn't, how much contractors actually pay in 2026, and how to get covered quickly. If you want the full picture of every policy a contractor may need, start with our contractor insurance guide.

Key Takeaways

General liability covers third-party bodily injury, property damage, and personal and advertising injury, plus your legal defense.
It does not cover your own employees, your tools, your vehicles, or the cost of redoing your own faulty work.
The standard contractor policy is $1M per occurrence / $2M aggregate.
Price depends mostly on your trade, number of employees, revenue, location, and claims history.
You can usually get a quote and a certificate of insurance online the same day.

What Does General Liability Insurance Cover for Contractors?

A commercial general liability (CGL) policy protects you when someone outside your business says your work hurt them or damaged their property. Here is what a standard policy includes.

Third-party bodily injury

A homeowner trips over an extension cord you left across a hallway and breaks a wrist. General liability can pay for their medical bills and your legal costs if they sue.

Third-party property damage

You drop a ladder and crack a client's granite countertop, or your crew damages a neighbor's fence while backing in materials. The policy can pay to repair or replace what you damaged.

Products and completed operations

This is the part many contractors forget. Claims often show up after the job is finished. For example, a pipe fitting you installed leaks two months later and ruins the client's hardwood floors. Completed operations coverage responds to that kind of damage.

Personal and advertising injury

Covers claims like libel, slander, or using someone else's photo in your ads without permission.

Medical payments

Small medical bills for a visitor injured at your site or office can be paid quickly, without anyone having to prove you were at fault.

Legal defense

Even a claim with no merit can cost thousands of dollars in attorney fees. Your insurer defends you, and those defense costs are usually paid in addition to your limits.

What General Liability Does NOT Cover

Many contractors assume their policy covers everything. It doesn't. These are the most common gaps and the policy that fills each one:

Not covered by general liability	Example	Policy that covers it
Injuries to your own employees	Your helper falls from a ladder	Workers' compensation
Fixing your own faulty work	Paint peels because the surface wasn't prepped	Not insurable; this is a business risk (warranty)
Design or advice mistakes	A layout you designed doesn't meet code	Professional liability (E&O)
Your tools and equipment	Your saws are stolen from the job site	Tools and equipment (inland marine) coverage
Vehicle accidents	You rear-end a car in your work truck	Commercial auto insurance
Claims above your limits	A lawsuit for $3 million	Commercial umbrella

Who Needs General Liability Insurance?

Almost every contractor who works on someone else's property. That includes:

General contractors who manage projects and hire subs.
Subcontractors, who are usually required to carry it by the general contractor. See our guide to subcontractor liability insurance.
Independent contractors and one-person businesses, because a single claim can put personal savings at risk. Read more about liability insurance for independent contractors.
Specialty trades such as electricians, plumbers, roofers, painters, HVAC technicians, landscapers, handymen, and cleaning companies.

When you'll be asked to show proof of coverage

Clients, especially commercial clients and property managers, often ask for a certificate of insurance before work starts.
General contractors require it from every subcontractor on the job.
Licensing boards and permit offices in many states and cities ask for proof of liability coverage before issuing or renewing a license. Requirements vary, so check with your state's contractor licensing board. See our guides for Florida, California, New York, and North Carolina.
Landlords may require it if you rent a shop, yard, or office.

What affects your price

Your trade: work at heights (roofing) or with water and gas (plumbing, HVAC) costs more to insure than low-risk trades.
Employees and payroll: more people on job sites means more chances for an accident.
Annual revenue: bigger jobs create bigger potential claims.
Location: rates change by state and even by city.
Claims history: past claims raise your premium.
Limits and deductible: higher limits cost more; a higher deductible lowers your premium.

Policy Limits, Certificates and "Additional Insured" Explained

Per-occurrence vs. aggregate limit

A policy written as $1M / $2M will pay up to $1 million for any single claim (per occurrence) and up to $2 million in total for all claims during the policy year (aggregate). Some large commercial jobs ask for higher limits; an umbrella policy is the cheapest way to add them.

Certificate of insurance (COI)

A COI is a one-page document that proves you have coverage. It lists your insurer, policy number, dates, and limits. Clients and general contractors will ask for one before you start. Most online insurers let you download a certificate instantly after you buy.

Additional insured

Many contracts require you to add the client or general contractor as an additional insured. That extends your policy's protection to them for claims that come from your work. It is added through an endorsement, and many insurers include it or charge a small fee. Read your contract carefully: it may ask for additional insured status for both ongoing and completed work.

Frequently Asked Questions

Is general liability insurance required by law for contractors?

There is no single federal law that requires it, but many states and cities require proof of liability insurance to get or renew a contractor license, and most clients and general contractors require it by contract. In practice, it is very hard to get work without it.

Does general liability cover my employees if they get hurt?

No. Injuries to your own employees are excluded. You need workers' compensation insurance, which most states require once you have employees.

Does general liability cover my tools?

No. Tools and equipment need their own coverage, often called inland marine or tools and equipment insurance.

Does it cover bad workmanship?

It does not pay to redo or repair your own faulty work. It can cover damage that your faulty work causes to other property, such as water damage from a leak you caused.

How fast can I get covered?

With online insurers, many contractors get a quote, buy a policy, and download a certificate of insurance on the same day.

Can I pay monthly?

Yes. Most insurers offer monthly payments, although paying the full year upfront is sometimes slightly cheaper.
