Introduction
A homeowner trips over a stack of lumber on your jobsite. A backhoe operator clips a neighbor's water line. A client claims your crew tracked debris into a space you never touched. A homeowner trips over a stack of lumber on your jobsite. A backhoe operator clips a neighbor's water line. A client claims your crew tracked debris into a space you never touched.
These moments happen fast, and the financial exposure that follows can outlast the project itself.
General liability insurance for contractors, often called commercial general liability or CGL, exists for exactly this kind of third-party claim. It responds when someone outside your business alleges you caused injury or property damage. It is not a catch-all policy that covers every loss a contracting business might face.
This article breaks down what CGL typically covers, where the common gaps sit, how contract requirements and endorsements shape your coverage, and what additional policies most contractors end up needing alongside it.
Key Takeaways
- Commercial general liability (CGL) answers third-party claims for bodily injury, property damage, personal and advertising injury, and eligible completed-operations losses.
- Defective workmanship, tool theft, employee injuries, and vehicle accidents generally sit outside CGL.
- Contracts often lock in limits, additional insured status, waivers of subrogation, and primary/noncontributory wording.
- Final coverage still hinges on insurer, classification, endorsements, and the exact policy language you buy.
What Does Contractor General Liability Insurance Cover?
Commercial general liability (CGL) is a third-party liability policy. That means it responds to claims made by someone other than you, not losses to your own business.
A typical claim follows a predictable path. An incident occurs, someone alleges you're responsible, and you notify your insurer. The insurer investigates, then the claim resolves through defense, settlement, or judgment, all subject to your policy's limits and conditions.
Bodily injury to third parties
This is the coverage most people picture when they think of general liability. It can respond when a non-employee, such as a customer, tenant, delivery driver, or passerby, is physically injured because of your operations or jobsite conditions.
Example: A visitor to a renovation site trips over unsecured materials, or a pedestrian is struck by falling debris from a roofing job. Costs can include:
- Medical expenses
- Legal defense fees
- Settlement payments
- Court-awarded damages
Employee injuries are a different story. Those are generally handled through workers' compensation, not CGL. If your business uses temporary workers or subcontractors, confirm how your policy classifies them. That distinction affects who is covered and how.
Property damage to third-party property
Coverage may apply when you accidentally damage property that belongs to a client, a neighbor, or another third party during the course of your work.
Common trade-specific examples include:
- An excavation crew striking a buried utility line
- A plumber's leak causing water damage in an adjacent unit
- A crew member scratching or damaging finished flooring while working nearby
There's an important distinction here: damage to surrounding or unrelated property is different from the cost of fixing the actual work you were hired to perform. The former may be covered; the latter usually isn't, which we'll get into shortly.
Personal and advertising injury
This coverage addresses non-physical claims tied to your business operations or marketing, such as libel, slander, or certain privacy and advertising-related offenses.
Example: A contractor uses a photo, logo, or slogan in marketing materials without permission and gets hit with a claim. This category can help, but not every intellectual-property dispute is automatically covered. The outcome depends heavily on the specific policy wording and applicable exclusions.
Products-completed operations
Completed-operations coverage addresses third-party bodily injury or property damage that shows up after you've finished the job, connected to work you already completed.
Real-world examples include:
- A railing installed months ago fails and injures a tenant
- An improperly installed fixture causes water damage down the line
- An HVAC component falls after installation, hurting someone below
Here's the nuance: the resulting third-party damage may be covered, but the cost of correcting your own defective work often isn't.
According to the standard ISO CGL form, work is treated as completed at the earliest of contract completion, jobsite completion, or intended use by another party. A separate aggregate limit typically applies to this hazard, so check your policy's "your work" language directly.
Legal defense and claim expenses
When a contractor gets sued, the defense provision matters as much as the coverage itself. This typically includes attorney fees, investigation costs, negotiation, and litigation expenses.
One detail that gets overlooked: whether defense costs sit inside or outside your policy limits.
Standard CGL policies generally treat defense costs as separate from the limit until settlement or judgment. Some policies use a "defense within limits" structure that eats into your available coverage as legal costs accrue. For a severe construction claim, that difference can be significant.
What Is Typically Not Covered by Contractor General Liability Insurance?
Understanding CGL means understanding what it leaves out. A policy might cover resulting third-party damage without covering your own property, employee injuries, business mistakes, or every obligation you signed up for in a contract.
The contractor's own faulty work or workmanship
If a plumber installs a fixture incorrectly and it needs to be redone, that repair cost is typically excluded. Same goes for a roofer who has to replace shingles installed wrong, or an electrician correcting a faulty wiring job.
The distinction that matters: the cost of redoing your own work is usually excluded, but damage that defective work causes to other property may still be covered, depending on the policy's language.
When a subcontractor performed the defective work on your behalf, the exclusion often doesn't apply the same way. Review your products-completed-operations and subcontractor-work provisions rather than assuming this distinction is universal across every policy.
Employee injuries and employment-related claims
Workers' compensation is generally the primary coverage for job-related employee injuries, and CGL isn't built to substitute for it. If you have employees, you need this coverage separately, and in most states, it's legally required.
Employment-related allegations, such as discrimination, harassment, wrongful termination, or retaliation, fall outside CGL entirely. Those exposures are typically addressed through employment practices liability insurance, a distinct policy type.
Owned property, tools, equipment, and materials
CGL doesn't insure your own trucks, tools, equipment, or materials against theft or damage. If a crew's tools get stolen from a jobsite trailer, or a piece of equipment is damaged in transit, general liability won't help.
Depending on what was damaged and where it was located, you may need:
- Commercial property insurance
- Inland marine or contractors' equipment coverage
- Builders risk insurance
- Installation coverage
Auto, pollution, professional, and contractual exposures
A few more categories fall outside standard CGL:
- Vehicle accidents involving owned or hired autos generally require commercial auto coverage, since CGL policies carry an auto exclusion.
- Pollution incidents typically need separate pollution liability coverage.
- Professional errors such as design, engineering, or estimating mistakes differ from physical accidental damage and usually require professional liability insurance.
- Contractual promises like missed deadlines or unfulfilled scope commitments aren't covered just because they appear in a signed contract. Contractual-liability terms decide what actually transfers.
How Do Contract Requirements, Endorsements, and Coverage Limits Affect Contractors?
Many contractors carry insurance not just for their own protection, but because a project owner, general contractor, lender, or public entity requires proof of coverage before work even begins.
Reading contract insurance requirements
Before signing, look for:
- Per-occurrence and aggregate limits the contract sets
- How long completed-operations coverage must continue after the job ends
- Minimum acceptable insurer financial ratings
- Notice and cancellation provisions
- Endorsements the contract names by form or wording
Requirements shift based on contract type, project size, jurisdiction, and how the parties allocate risk. Don't assume a limit that worked on your last job, or a number a fellow contractor mentioned, applies here.
Compare the contract's indemnification language against your actual policy, especially if you're assuming responsibility for subcontractors or unusual hazards.
Additional insured status
An additional insured endorsement extends specified liability protection to a project owner or general contractor for claims tied to your operations. There are two flavors worth knowing:
- Ongoing-operations coverage, which applies while work is in progress
- Completed-operations coverage, which applies after the job wraps
The requested endorsement form and its exact wording matter. And here's a common trap: a certificate of insurance shows evidence that a policy exists, but it doesn't create coverage on its own. According to IRMI's guidance on certificate errors, only the actual policy endorsement can change what's covered.
Waiver of subrogation and primary/noncontributory wording
A waiver of subrogation limits your insurer's ability to go after a specified party after paying a covered claim. Primary and noncontributory wording determines whose policy responds first when multiple policies could apply.
Quick example: A general contractor requires primary and noncontributory wording from a subcontractor's CGL policy. If the subcontractor's policy doesn't actually carry that endorsement, even an active, paid-up CGL policy can create a contract-compliance problem on the jobsite.
Per-project aggregate and umbrella or excess limits
A per-project aggregate endorsement, known formally as the designated construction project general aggregate, reserves limits to a specific job rather than spreading them across every project you're running. According to IRMI's definition, this doesn't change your other limits, including the products-completed-operations aggregate.
Contractors handling multiple simultaneous projects, larger contracts, or higher-severity exposures often need umbrella or excess liability on top of standard limits. Rather than picking an arbitrary number, check what your specific contracts actually require.
What Other Insurance May Contractors Need, and How Should They Review a Policy?
General liability is one piece of a larger insurance program, not blanket coverage for every business risk. Depending on your operations, you may also need:
| Coverage | What It Handles |
|---|---|
| Workers' compensation | Employee injury and workplace liability |
| Commercial auto | Owned or hired vehicle accidents |
| Commercial property | Buildings, contents, physical assets |
| Inland marine / contractors' equipment | Tools and equipment in transit or off-site |
| Builders risk | Property during construction |
| Professional liability | Design and consulting errors |
| Pollution liability | Environmental incidents |
| Umbrella / excess liability | Limits beyond your primary policies |
A quick review checklist:
- Confirm the named insured matches your actual business operations.
- Review classifications and exclusions for accuracy.
- Check limits and deductibles against current contracts.
- Verify subcontractor insurance requirements.
- Match endorsements to what your active contracts actually demand.
Revisit your coverage after any major shift:
- Adding a new trade
- Hiring employees
- Buying equipment
- Taking on bigger projects
- Bringing on new subcontractors
These changes often create gaps that don't show up until a claim hits.

Frequently Asked Questions
What damages are covered by a CGL policy?
CGL generally covers third-party bodily injury, third-party property damage, personal and advertising injury, and eligible completed-operations claims. Exclusions, limits, deductibles, and specific policy wording ultimately determine the outcome of any claim.
What is typically not covered by general liability insurance?
Common gaps include your own faulty workmanship, employee injuries, damage to owned tools and equipment, vehicle accidents, pollution incidents, professional errors, and certain contractual or purely financial losses.
Should a subcontractor have their own insurance?
Yes. Subcontractors are commonly expected to carry their own CGL and other required coverage, provide a certificate of insurance, and meet any additional insured or endorsement requirements spelled out in the contract.
What are the insurance requirements for contracts?
Requirements vary by project, but they often address liability limits, completed-operations duration, additional insured status, waiver of subrogation, primary and noncontributory wording, certificates, and sometimes umbrella or excess coverage.
What insurance do I need if I am self-employed?
Beyond general liability, self-employed contractors often need commercial auto, tools and equipment coverage, workers' compensation where required by law, professional liability, and any coverage specifically required by client contracts.
Is it better to get liability or full coverage?
"Full coverage" isn't a standard commercial insurance product. Most contractors need a coordinated package built around their employees, vehicles, property, equipment, professional services, and contractual obligations, not a single policy.
