General Liability Insurance for Contractors: 2026 Guide

Top of PM Hub

General liability insurance is the single most important coverage a contractor can carry. It's required for licensing in most states, required by virtually every commercial contract, and the one policy that stands between your business and a lawsuit that could wipe you out. Understanding what it covers, what it doesn't, and how much you actually need is fundamental to running a contractor business at any level.

What General Liability Insurance Actually Covers

General liability insurance covers three core categories of risk: bodily injury, property damage, and personal and advertising injury. For contractors, the first two are the ones that matter most day to day.

Bodily injury covers medical expenses, legal fees, and settlements when someone is injured as a result of your operations. A homeowner trips over your equipment on the job site. A passerby gets hit by debris during demolition. A client's employee slips on a wet surface your crew created. These are the scenarios general liability is built to cover. Without it, those medical bills and legal costs come directly out of your pocket.

Property damage covers damage you or your crew cause to someone else's property in the course of your work. You nick a gas line during excavation. A ladder falls through a window. A subcontractor backs a truck into a client's fence. Property damage claims are among the most common in the contractor world and they happen to experienced crews just as often as inexperienced ones.

Personal and advertising injury covers things like libel, slander, and copyright infringement. As the DC Department of Licensing and Consumer Protection explains, a CGL policy shields your business from the expenses of out-of-court settlements, litigation, and court rulings across all three of these categories.

What general liability does not cover is equally important to understand. It does not cover your own equipment or tools. It does not cover injuries to your employees, which falls under workers' comp. It does not cover your vehicles, which falls under commercial auto. And it does not cover professional errors or advice, which requires professional liability or errors and omissions coverage.

How Much General Liability Coverage Do Contractors Actually Need

The standard general liability policy for contractors is written with a $1,000,000 per occurrence limit and a $2,000,000 aggregate limit, a structure used as the baseline by California's Department of General Services and most other state agencies. Per occurrence means the maximum the policy will pay for a single incident. Aggregate means the maximum it will pay across all claims during the policy period, typically one year.

For most residential contractors doing standard work, a $1,000,000 per occurrence policy is the baseline. For commercial contractors working in higher-risk environments such as high rises, industrial sites, or public infrastructure, $2,000,000 per occurrence is increasingly the standard requirement. As IRMI notes in their contractor insurance guidelines, there may be unique exposures on specific projects that dictate higher limits than standard minimums, and contractors should consult with their insurance agent to determine what additional requirements may be needed.

Many commercial contracts and GC subcontractor agreements require $1,000,000 to $2,000,000 per occurrence as a condition of being on the approved vendor list. Some large commercial GCs and municipalities require $3,000,000 or more. Review the insurance requirements section of every contract before you price the job. Finding out you're underinsured after you've committed to the work is a costly problem.

An umbrella policy provides excess liability coverage that sits on top of your general liability, commercial auto, and workers' comp. A $1,000,000 umbrella policy typically costs a few hundred dollars a year and can be the difference between a covered claim and a personally devastating one.

What Drives the Cost of General Liability for Contractors

General liability premiums for contractors vary significantly based on several factors.

Type of work is the biggest driver. Roofing contractors pay some of the highest general liability rates in the trades because of the inherent risk of working at height. Excavation and demolition contractors pay high rates because of underground utility risk, structural damage exposure, and potential environmental contamination. Painting and finish contractors pay relatively lower rates because the exposure profile is lower. Your specific trade classification determines a large portion of your base rate.

Revenue is the other major driver. Most general liability policies for contractors are rated on payroll or revenue. The more you bill, the more exposure the insurer assumes and the higher your premium. As your business grows, your general liability premium will grow with it.

Claims history affects your rate over time. A contractor with clean loss runs over the past three to five years will pay less than one with a history of claims. Managing job site safety aggressively is not just the right thing to do. It directly affects your insurance costs year over year.

Location affects rates as well. States with higher litigation rates and larger jury awards carry higher premiums than states with more limited tort environments.

PRO-TIP: Your general liability policy has an aggregate limit, the maximum it will pay across all claims in a policy year. On a busy year with multiple jobs and multiple incidents, it is possible to exhaust your aggregate before the policy renews. If you are doing significant volume, confirm with your agent that your aggregate limit is adequate for your annual exposure, not just your per occurrence limit.

'Additional Insured' Endorsements

On virtually every commercial job you'll work, the GC or property owner will require you to add them as an additional insured on your general liability policy. An additional insured endorsement extends your coverage to protect the named party against claims arising from your work.

As King County's contract insurance requirements specify, additional insured endorsements must be included with the certificate of insurance before work begins. The endorsement must be requested and confirmed before you mobilize, not after a claim is filed.

Some policies include blanket additional insured coverage, meaning anyone you are contractually required to name as additional insured is automatically covered without a separate endorsement for each project. If you work on multiple commercial projects simultaneously, blanket additional insured coverage eliminates the administrative work of adding endorsements job by job.

Claims Made vs. Occurrence Policies

Most contractor general liability policies are written on an occurrence basis, meaning the policy covers incidents that occur during the policy period regardless of when the claim is filed. If something happens on a job in March and the client files a claim two years later, your policy from the time of the incident covers the claim.

Some policies, particularly professional liability policies, are written on a claims-made basis, meaning the policy must be active both when the incident occurs and when the claim is filed. If your policy lapses and a claim comes in after the lapse, you are not covered. Contractors who carry professional liability need to maintain continuous coverage to protect against claims that surface after a policy term ends.

For general liability specifically, occurrence-based policies are standard in the contractor market and preferred for the protection they provide against delayed claims.

Watch Out: Completed Operations Coverage Has Its Own Limits

Completed operations coverage, the portion of your general liability policy that covers claims arising from work you have already finished, often has its own sublimit separate from your per occurrence and aggregate limits.

A contractor who does $2,000,000 in work in a year and has a $2,000,000 aggregate general liability policy might assume they are fully covered. But if their completed operations sublimit is $1,000,000 and a claim comes in on a completed project that exhausts that sublimit, subsequent claims on completed work are not covered even if the main aggregate has not been touched.

Review your policy specifically for completed operations limits. On larger commercial projects, verify that your completed operations coverage is adequate for the scope of work you have done before the project closes out, not after a claim surfaces.

Bottom Line

General liability insurance is non-negotiable for contractors at any scale. It covers the bodily injury and property damage claims that happen on every job site at some point in every contractor's career. A $1,000,000 per occurrence policy with a $2,000,000 aggregate is the standard baseline, and commercial work typically requires more. NEXT Insurance, Hiscox, Simply Business, and Liberty Mutual all offer contractor coverage with online quotes and same-day certificates. Get properly covered, read every contract's insurance requirements before you sign, and manage your additional insured endorsements before work starts, not after something goes wrong.

FAQ: General Liability Insurance for Contractors

Does general liability cover my own faulty workmanship?

Generally no, and this surprises a lot of contractors. GL is designed to cover third-party bodily injury and property damage caused by your operations, not the cost of redoing work that was done incorrectly. If your crew installs a roof incorrectly and water damage results, your GL policy may cover the damage to the interior of the home caused by the leak, but it typically will not pay to tear off and replace the roof itself. That is considered the cost of your own defective work, which falls outside the scope of what GL is built to cover. Some policies include limited coverage for property damage resulting from faulty workmanship under specific conditions, but the work itself is almost always excluded. This is why contractors doing significant volume often carry a separate contractor's errors and omissions policy or make sure their completed operations coverage is robust enough to handle consequential damage claims.

Does my general liability policy cover subcontractors working under me?

Not automatically, and assuming it does is one of the more expensive mistakes a GC can make. Your GL policy covers your operations and your employees. Subcontractors are generally treated as separate businesses, and claims arising from their specific work may not be covered under your policy if they caused the damage independently. This is why most GC contracts require every subcontractor to carry their own GL policy and name the GC as an additional insured. If a subcontractor causes damage and has no coverage of their own, you may end up defending a claim on your policy for work you did not perform. The practical fix is requiring current certificates of insurance from every subcontractor before they mobilize, verifying that their completed operations coverage matches the scope of their work, and making sure your own policy includes a subcontractor liability provision if you regularly use uninsured or underinsured subs.

Do I need general liability insurance if I am a sole proprietor or one-person operation?

Yes. Business structure does not change your liability exposure. As a sole proprietor, you and your business are legally the same entity, which means any judgment against your business is a judgment against you personally. Your home, your vehicle, your savings, and your personal assets are all on the table if someone sues you for a job site injury or property damage and you have no insurance to respond to the claim. Beyond the personal exposure, most GCs will not allow a sole proprietor on a commercial job site without a current certificate of insurance, and many residential clients now ask for proof of coverage before signing a contract. A basic GL policy for a small sole proprietor operation typically costs between $500 and $1,500 per year depending on trade and location. That is a straightforward cost of being in business, not an optional expense.
