General Liability Insurance For Contractors
The first policy most clients, landlords, and general contractors ask for before a crew enters a job site.

You run a crew. You have bids to send, jobs to start, customers waiting, and GCs asking for proof of insurance. This guide is built to help a US contractor choose fast without reading twenty carrier websites.
What General Liability Insurance Actually Covers
General liability is third-party cover. It responds when your work injures somebody who does not work for you, or damages property that does not belong to you. That is the whole logic of the policy, and it explains almost every question contractors have about it.
Covered
- Bodily injury to a client, a visitor or a passer-by on or near your job site
- Damage to a customer’s property caused by your operations
- Products and completed operations — damage that shows up after you have finished and left
- Personal and advertising injury, such as libel, slander or copyright issues in your marketing
- Legal defence costs, including for a claim that turns out to be groundless
Not covered
- Injuries to your own employees — that is workers’ compensation
- Your own tools, equipment and materials — that needs inland marine or equipment cover
- The cost of redoing your own defective work — the “your work” exclusion
- Mistakes in design, specification or professional advice — that is professional liability
- Accidents involving vehicles — that is commercial auto
- Most pollution incidents
Policy Limits: Per Occurrence vs Aggregate
Every general liability quote you receive is built on two numbers, and contractors routinely confuse them. The per occurrence limit is the most the insurer will pay for a single claim. The aggregate is the most it will pay across the entire policy year, no matter how many claims you make.
| Limit | Typical amount | What it caps |
|---|---|---|
| Per occurrence | $1,000,000 | The maximum for any single claim |
| General aggregate | $2,000,000 | The maximum across the whole policy year |
| Products & completed operations aggregate | Often separate | Claims arising after the job is finished |
| Damage to premises rented to you | Sub-limit | Property you occupy rather than own |
| Medical expense | Small sub-limit | Minor injuries settled without a liability finding |
The $1M/$2M pairing has become the de facto contractual standard in US construction, which is why most carriers quote it by default. The aggregate resets at renewal, not after each claim — so a bad year can quietly erode the protection you have left for the months still to run.
Larger commercial jobs, public contracts and many general contractors ask for more than $1M. Raising the general liability limit itself is rarely the cheapest route; a commercial umbrella policy sits on top of the general liability and lifts the ceiling for considerably less.
The Certificate of Insurance and Additional Insured Status
For most contractors this is the part that actually blocks work. The general contractor is not asking whether you are insured; they are asking for a document, with specific wording, before your crew is allowed on site.
Get the requirements in writing first
Limits, additional insured status, waiver of subrogation and primary and non-contributory wording are separate requests. Asking once, in writing, avoids three rounds of reissued certificates.
Give your carrier the exact legal name
The certificate holder must be spelled exactly as it appears in the contract, with the right address. A trading name instead of the registered entity is the single most common reason a certificate is rejected.
Understand what the certificate is not
A certificate is evidence that a policy exists. Additional insured status is an endorsement added to your policy, extending your cover to that party. Listing somebody on the certificate does not, by itself, make them an additional insured.
Watch the dates
A certificate expires with the policy behind it. If your renewal lapses mid-project, your certificate is void and the site can shut you out until a new one arrives.
The mechanics of requesting, correcting and renewing certificates are covered in our certificate of insurance guide.
Exclusions That Surprise Contractors
Most disputes with an insurer are not about whether you had cover. They are about whether the loss fell inside it. These are the gaps that catch working contractors most often.
- Your own work. General liability pays when your work damages something else. It does not fund the tear-out and rebuild of the defective work itself.
- Uninsured subcontractors. If a sub causes damage and carries no cover of their own, the claim can land on your policy — and your premium. Collect their certificates before they start, every time.
- Employee injury. Anyone on your payroll falls under workers’ compensation, not general liability, and the distinction between employee and subcontractor is decided by the facts, not by what the paperwork calls them.
- Professional services. Design-build work, specification and consulting sit outside general liability. That exposure belongs to professional liability cover.
- Pollution. Standard policies exclude most pollution incidents, and depending on the wording that can extend to mould, fumes, lead and asbestos.
- Tools and equipment. Your own gear is never general liability. Theft from a truck or a job site needs equipment cover.
What Drives Your General Liability Premium
Two contractors in the same city, with the same limits, can be quoted very different premiums. The variables carriers actually price on are these:
- Trade classification. Work at height and structural work — roofing, framing, demolition — is rated far above painting, flooring or handyman work.
- Payroll and revenue. Most contractor policies are rated on one or both, and reconciled at the end of the term.
- Limits and deductible. The gap between $1M and $2M per occurrence is usually smaller than contractors expect.
- Claims history. Frequency hurts more than severity: three small claims typically read worse than one large one.
- States you operate in. Litigation climate and construction statutes vary enough to move the price on identical work.
- Subcontractor use. Carriers ask how much you sub out and whether those subs carry their own cover, because uninsured subs become your exposure.

How To Choose Your General Liability Policy
Start from the contract, not the price
Read what the job actually demands before you shop: the limit, additional insured status, and any waiver of subrogation wording. A cheaper policy that fails the requirement costs you the job, not just the difference in premium.
Match the cover to your real exposure
Employees mean workers’ compensation. Trucks mean commercial auto. Expensive tools mean equipment cover. General liability handles the third-party risk and nothing else — the gaps have to be filled deliberately.
Check how fast you can get a certificate
If your work depends on producing proof of insurance quickly, the speed and flexibility of the certificate process matters more day to day than a small difference in premium.
General Liability Insurance for Contractors: FAQ
Do I need general liability insurance as a sole trader with no employees?
Usually yes, and not because of headcount. General liability responds to damage and injury you cause to third parties, so it applies whether you work alone or run twenty crews. What changes with employees is workers’ compensation, which is a separate policy. In practice most sole traders buy general liability because clients and general contractors will not let them start without proof of it.
How much general liability insurance do contractors need?
$1,000,000 per occurrence and $2,000,000 aggregate is the baseline written into most US construction contracts. Larger commercial work, public projects and many general contractors ask for higher ceilings, which are normally reached with a commercial umbrella sitting above the general liability rather than by raising the underlying limit.
Does general liability cover damage to my own work?
No. This is the exclusion that causes the most disputes. If your work damages someone else’s property, the policy responds. If the defect is in the work itself, tearing it out and redoing it is your cost. Cover for that sits in separate products such as contractors’ professional or specific warranty arrangements.
What is the difference between a certificate of insurance and additional insured status?
A certificate is evidence that a policy exists on a given date. Additional insured status is an endorsement that extends your policy’s protection to another party, typically the general contractor or property owner. Being named on a certificate does not by itself create that status — the endorsement has to be added to the policy.
Does general liability cover my tools if they are stolen?
No. Tools, equipment and materials you own are never covered by general liability, which is strictly third-party cover. Theft from a truck or a job site needs inland marine or a dedicated tools and equipment policy.
What happens if my subcontractor is uninsured?
The claim can be directed at your policy, and your premium and claims history absorb it. Carriers ask how much work you sub out precisely because uninsured subs become your exposure. Collecting a current certificate from every sub before they start is the cheapest risk control available to a contractor.
