General Liability Insurance for Contractors
Most construction clients ask for proof of general liability insurance before a contractor sets foot on the job site. That requirement exists because construction generates liability from multiple directions at once: bodily injury, property damage, subcontractor disputes, and third-party lawsuits that name everyone on the project, regardless of who caused the problem.
Farmer Brown has placed commercial general liability coverage for contractors across all 50 states since 1996. This guide covers what the policy covers, what it costs by trade, what it does not cover, and how to choose limits that match real exposure rather than just a contract minimum.
What general liability insurance for contractors covers
A general liability policy, also called commercial general liability or CGL, pays when a client or third party claims your operations caused them physical harm or financial damage. There are four categories of claims a standard GL policy addresses.
Bodily injury caused by your work or your employees
The most common GL claim in construction. If someone outside your company is physically injured because of something you or an employee did, or failed to do, the policy pays their medical expenses, lost income, and related costs, plus legal defense if they sue.
A real example: an employee unloading materials from a flatbed does not see a site visitor crossing behind the truck. The visitor is knocked down and breaks a leg. The contractor gets named in the lawsuit. General liability responds. Employee injuries are handled separately by workers compensation.
Property damage caused to someone else’s property
If your work or your crew damages property belonging to a client or a third party, general liability pays repair or replacement costs plus legal defense. It does not cover damage to your own tools, materials, or property.
A real example: a contractor installing a new kitchen does not shut off the water supply before disconnecting a line. The leak floods the basement. The homeowner sues for the damage. General liability covers it.
Personal injury claims, including defamation
This category covers non-physical harm to a person’s reputation or well-being. Libel, slander, malicious prosecution, wrongful arrest, and privacy violations fall under personal injury in a GL policy. Less common for contractors, but worth knowing.
A real example: a contractor tells a client that a competitor’s work is substandard. The client cancels their contract with that competitor. The competitor sues for damages to its reputation and finances. General liability responds.
Advertising and marketing injury
If your advertising or marketing materials cause damage to another business or individual, including copyright infringement, the GL policy can respond.
A real example: a contractor publishes a project portfolio using a manufacturer’s brand logo without written permission. The manufacturer pursues damages. Advertising injury coverage applies.
What general liability insurance does not cover
| Excluded claim type | What covers it instead |
|---|---|
| Employee injuries on the job | Workers compensation |
| Damage to your own tools, materials, or property | Inland marine or equipment floater |
| Damage to your own completed work | Contractor’s professional liability or warranty |
| Professional design errors or negligence | Professional liability (errors and omissions) |
| Intentional acts or illegal wrongdoing | Not insurable |
| Pollution or hazardous materials | Pollution liability endorsement |
| Commercial vehicle accidents | Commercial auto insurance |
| Injuries to your employees | Workers compensation |
Contractors who assume their GL policy covers everything that happens on a job site find out otherwise when a claim gets denied.
How much does general liability insurance cost for contractors
GL premium for contractors is calculated as a percentage of annual revenue, not a flat monthly rate. The type of work is the single biggest driver of the base rate. Location, payroll, number of employees, claims history, and coverage limits all move the number from there.
GL cost by annual revenue: general contractors and roofers
These figures reflect Farmer Brown quoted rates. General contractors pay approximately 0.75 percent of annual revenue with a $1,600 minimum. Roofing contractors pay approximately 1 percent of annual revenue with a $2,800 minimum.
| Annual revenue | General contractor GL cost | Roofing contractor GL cost |
|---|---|---|
| Under $215,000 | $1,600 (minimum applies) | $2,800 (minimum applies) |
| $250,000 | $1,875 | $2,800 (minimum applies) |
| $300,000 | $2,250 | $3,000 |
| $500,000 | $3,750 | $5,000 |
| $750,000 | $5,625 | $7,500 |
| $1,000,000 | $7,500 | $10,000 |
| $2,000,000 | $15,000 | $20,000 |
Figures assume a clean claims history, standard $1M/$2M limits, and no unusual subcontractor exposure.
GL cost by risk tier: other contractor trades
Rates for other trades vary by class code. The table below reflects general market tiers rather than confirmed rate percentages, since pricing for each trade depends on carrier, state, and underwriting details.
| Risk tier | Contractor types | What drives the rate |
|---|---|---|
| Lower risk | Painting, drywall, flooring, cleaning | Primarily property damage exposure, limited bodily injury risk |
| Moderate risk | Electrical, plumbing, HVAC, carpentry | Equipment use, property damage, and some injury exposure |
| Higher risk | General contractors, excavation, and concrete | Heavy equipment, coordination of multiple subs, broader liability |
| Highest risk | Roofing, demolition | Height exposure, catastrophic injury potential, significant property damage risk |
For confirmed rate quotes on specific trades, Farmer Brown provides same-day pricing across all 50 states.
What affects your GL premium
Beyond trade type and revenue, four variables consistently move contractor GL pricing:
Claims history. A single significant GL claim can raise renewal premiums 20 to 40 percent and stay on record for three to five years. Contractors with clean records get the most competitive rates.
Subcontractor practices. Carriers treat uninsured subcontractor labor as the general contractor’s own payroll during audits. Every sub should provide a current certificate of insurance with additional insured status before work begins.
Coverage limits. A $2 million per-occurrence limit costs more than a $1 million limit. Umbrella policies are typically the most efficient way to reach higher total limits without inflating the base GL premium.
Location. States with higher average verdicts or stricter statutory requirements produce higher premiums for identical work.
Coverage limit options for contractors
Most contractor GL policies start at $1 million per occurrence and $2 million aggregate. That is the baseline for most client contract requirements on smaller residential and light commercial projects. Larger commercial projects, government contracts, and general contractors managing multiple subcontractors often need higher limits.
| Limit structure | Best suited for | How to reach it |
|---|---|---|
| $1M per occurrence / $2M aggregate | Small contractors, residential work, basic contract requirements | Standard GL policy |
| $2M per occurrence / $4M aggregate | Mid-size operations, commercial projects, and larger client requirements | Endorsed GL policy or separate umbrella |
| $5M total and above | Large commercial projects, government contracts, high-value work | Commercial umbrella policy over primary GL |
Products-completed operations coverage is a separate aggregate within the GL policy that covers claims arising after a project is finished. For contractors, this is the coverage that responds when a client discovers damage or injury months or years after the work was completed. Make sure the policy includes it and that the limit is adequate for the type of projects being completed.
How a GL claim works in practice
When a covered claim is filed against a contractor, the policy responds in three ways: it pays legal defense costs, including attorney fees and court expenses; it covers settlements negotiated before trial; and it pays judgments awarded by the court up to the policy limit.
Legal costs alone on a contested construction liability claim can reach $30,000 or more before the case is resolved. For smaller contractors, defense costs frequently exceed the settlement amount. The GL policy absorbs those costs.
The general contractor is frequently named in construction lawsuits regardless of who caused the damage. A subcontractor’s error becomes the general contractor’s legal problem when the project owner files suit. If the general contractor is listed as an additional insured on the subcontractor’s policy, the subcontractor’s carrier handles the defense and any judgment. Without that additional insured status, the general contractor’s own carrier responds.
Additional coverages contractors often need alongside GL
General liability is the starting point, not the complete picture. Depending on the trade and the type of projects, contractors commonly need:
| Coverage | What it covers | Who typically needs it |
|---|---|---|
| Workers compensation | Employee injuries and illness on the job | Required in most states for any employee |
| Commercial auto | Accidents involving business vehicles | Any contractor using trucks, vans, or work vehicles |
| Builders risk | Physical damage to a structure under construction | General contractors and project owners |
| Inland marine/equipment floater | Tools and equipment in transit or on site | Any contractor with significant equipment investment |
| Commercial umbrella | Liability above primary policy limits | Contractors with large projects or high-value contracts |
| Professional liability | Design errors, professional negligence | Design-build contractors, engineers, architects |
| Contractor’s pollution liability | Pollution and environmental damage claims | Excavation, HVAC, painting, any work near hazardous materials |
A Business Owner Policy (BOP) combines general liability and commercial property coverage at a lower combined price than buying each separately. Not every contractor qualifies, but for smaller operations without significant equipment exposure, a BOP is worth pricing alongside a standalone GL.
How to choose GL limits that match your actual exposure
Contract minimums are a floor, not a coverage recommendation. A client requiring $1 million in GL coverage is protecting their interests. That figure may or may not reflect the contractor’s actual liability exposure.
Two questions determine the right limit. First, what is the realistic worst-case claim on the type of projects you complete? A contractor working on a $2 million commercial build has different exposure than one doing $50,000 residential renovations. Second, what are your total business assets? A judgment that exceeds policy limits is paid directly from those assets.
For most contractors doing commercial work, a $1 million per occurrence limit with a $1 million commercial umbrella on top provides $2 million in total protection at a cost that is typically more efficient than buying a $2 million GL policy outright.
Frequently asked questions about GL insurance for contractors
Is general liability insurance required for contractors?
Most states require GL coverage as a condition of contractor licensing. Clients require it as a condition of the contract. In practice, a contracting business cannot operate without it.
Does GL insurance cover subcontractors working on my projects?
Not automatically. A GL policy covers your operations, not a subcontractor’s independent work. The right structure is to require every subcontractor to carry their own GL policy and add you as an additional insured. That way, when a subcontractor’s error causes a claim, their carrier responds first.
What is the difference between per occurrence and aggregate limits?
The per-occurrence limit is the maximum the carrier pays for a single claim. The aggregate is the maximum paid across all claims during the policy period. A $1M/$2M policy pays up to $1 million on any one claim and up to $2 million total across all claims in the year.
Does GL insurance cover completed work?
Products-completed operations coverage, a component of most GL policies, covers claims arising after a project is completed. Confirm it is included and that the limit is adequate for the scope of your projects.
What happens if I have a claim during the policy period?
Report it to your carrier as soon as possible. Most GL policies operate on an occurrence basis, meaning a claim is covered if the incident happened during the policy period, regardless of when it is reported. Delayed reporting can create complications.
Can I get a certificate of insurance the same day?
Farmer Brown issues certificates of insurance within four hours of binding coverage. Same-day quotes are available for most contractor trades across all 50 states.
How does claims history affect my renewal premium?
A single significant claim typically raises renewal premium by 20 to 40 percent and stays on record for three to five years. Multiple claims in that window can make coverage harder to obtain at standard rates. Smaller incidents that can be handled out of pocket are sometimes cheaper to absorb directly than the premium increase that follows filing.
