Key Takeaways
General contractor liability insurance starts at about $133 per month from one broker benchmark, but the real premium depends on revenue, work mix, subcontractor cost, and loss history.
- A broker benchmark puts the annual minimum at $1,600 for a small general contractor under about $215,000 in revenue with clean loss history and standard $1M/$2M limits
- Completed operations coverage and the subcontractor exception to the 'your work' exclusion are important provisions to review before and after the project ends
- A certificate of insurance does not create additional insured rights, primary and noncontributory status, or waiver of subrogation protection; those depend on policy endorsements
- Two quotes with the same per-occurrence limit can differ on completed operations treatment, residential exclusions, aggregate structure, and subcontractor provisions, so compare policy terms before comparing price
How much does general contractor liability insurance cost?
General liability (GL) for a general contractor does not have one standard price. The premium depends on annual revenue, work mix, subcontractor cost, state, limits, and loss history.
One broker benchmark puts the annual minimum at about $1,600 per year (roughly $133 per month) for a general contractor under approximately $215,000 in annual revenue, with clean loss history, standard $1 million per occurrence and $2 million aggregate limits, and no unusual subcontractor exposure. That benchmark uses a rate of about 0.75% of annual revenue.
That number is a broker benchmark, not a guaranteed quote or a market average. A general contractor coordinating multiple trades can depart quickly from a small-account minimum.
What raises the premium from that starting point
The broker benchmark above uses annual revenue as its exposure base. Carriers may use revenue, payroll, subcontractor cost, or other measures depending on the policy and program. Revenue alone does not determine the premium.
- Work mix: new construction, remodeling, residential, commercial, and industrial work each carry different risk profiles. Carriers may classify and price a general contractor that self-performs roofing, concrete, or excavation differently from one that subcontracts those trades.
- Subcontractor cost: many carriers ask for the total cost of subcontracted work. Subcontractor cost, subcontractor insurance status, and written agreements may all factor into the carrier's pricing and eligibility decision.
- State: project geography influences both loss exposure and the legal environment. Carriers may underwrite a single-state residential contractor differently from a multistate commercial general contractor.
- Loss history: carriers ask about prior claims, including water, fire, fall, and construction-defect losses. Claims history may affect both pricing and eligibility, and underwriters may also ask what corrective steps were taken after a loss.
- Limits and endorsements: the limits selected, aggregate structure, and endorsements required by contracts (such as additional insured and waiver of subrogation) may all affect the premium and the terms a carrier offers.

What general liability covers for a general contractor
General liability for a general contractor is third-party coverage. The core promise generally concerns sums the insured becomes legally obligated to pay for covered bodily injury or property damage, plus defense costs, subject to limits, exclusions, and endorsements.
It is not a warranty, a maintenance contract, or an all-risk package. Here is what it typically addresses and what it does not.
Business-risk exclusions that matter for general contractors
Construction claims frequently turn on the standard business-risk exclusions. An industry analysis identifies the exclusions commonly labeled j, k, and l as prominent provisions in construction-defect disputes. These provisions generally address:
- Property under the insured's management or control
- Damage to the insured's own product
- Damage to the insured's own work
The application of these exclusions depends on what was damaged, when it was damaged, who performed the work, which entity seeks coverage, and the exact policy wording. A plumbing error that requires replacement of the incorrectly installed pipe is a different coverage question from water from that error damaging finished floors and a neighboring unit.
Care, custody, or control
When a general contractor takes charge of an owner's property, rented equipment, stored materials, or another party's personal property, the care, custody, or control exclusion can apply. An industry analysis explains that the exclusion can have different results for a named insured and an additional insured. Control attributed to a subcontractor may not necessarily be attributed to an upstream general contractor in the same way.
The buyer lesson: disclose unusual custody exposures in the application instead of assuming the ordinary property-damage grant covers everything physically present at the site.
What requires a separate policy
General liability is one piece of a general contractor's insurance program. Several exposures require their own coverage lines:
- Workers compensation and employers liability for employee injuries
- Commercial auto for vehicle accidents
- Tools and equipment (inland marine) for the contractor's own tools and equipment
- Contractors pollution liability for pollution events restricted by standard GL pollution exclusions
- Builders risk for physical loss to the project itself
- Professional liability for design, engineering, or construction-management errors
Completed operations and subcontractor coverage gaps
General contractors have an unusually important post-completion exposure. An installation error can remain hidden until water intrusion, fire, collapse, or another loss occurs months or years after the project.
A products-completed operations exclusion can remove coverage for bodily injury or property damage arising after the work is completed and accepted. Examples include a later fire from faulty wiring and water damage from inadequate flashing. This is not proof that every policy contains that exclusion, but it is a reason to check whether completed operations coverage is included and whether any trade, project, or residential endorsements narrow it.
The subcontractor exception and why it matters
The "your work" exclusion and its subcontractor exception are central to a general contractor's policy review. The broad question is whether property damage to the general contractor's completed work, arising from work performed by a subcontractor, remains within the policy's potential coverage.
The answer depends on the form and endorsements. A policy can modify or remove the subcontractor exception found in a standard form, and manuscript exclusions can be broader than a buyer expects. Review the actual policy forms, not merely a declaration page.
Four subcontractor coverage questions every general contractor should answer
Separate these four questions before assuming subcontractor work is covered.
Does the general contractor's own policy include completed operations coverage for the operations and project types it actually undertakes?
Does the policy retain or remove the subcontractor exception to the 'your work' exclusion?
Does each subcontractor's policy cover its trade and both ongoing and completed operations?
Is the general contractor protected as an additional insured on the subcontractor's policy for the phases and parties the written subcontract requires?
A subcontractor's certificate showing a policy number and limits does not establish that a later claim involving that subcontractor's completed work will protect the general contractor.
Why a certificate of insurance is not enough
A certificate of insurance is evidence and an administrative snapshot. It is not the endorsement that changes the insurance contract. An insurance compliance guide states that endorsements determine who is an additional insured, which operations are covered, and whether completed work is included. Those rights are expressly distinguished from the certificate.

Additional insured endorsements and contract requirements
General contractors occupy both sides of additional insured requirements. An owner may require the general contractor to name the owner as an additional insured. The general contractor then requires the same from subcontractors. The chain works only when the written agreements, insurance requirements, and endorsements align.
CG 20 10 and CG 20 37: ongoing versus completed operations
CG 20 10 is associated with additional insured protection for ongoing operations. CG 20 37 is associated with completed operations. An insurance education source explains that the former addresses liability connected to the named insured's ongoing work, while the latter is used for the post-completion phase.
Form edition matters. Older and newer editions do not necessarily grant identical scope. A contract that names only a form number without an edition can create ambiguity. A policy containing a blanket additional insured endorsement may apply only when a written contract was executed before the loss.
| Endorsement | Phase covered | Key consideration |
|---|---|---|
| CG 20 10 | Ongoing operations | Edition and wording vary; confirm the form matches the contract requirement |
| CG 20 37 | Completed operations | Often required alongside CG 20 10 so the upstream party has post-completion protection |
| Blanket additional insured | Ongoing (and sometimes completed) | May apply only when a written contract was executed before the loss; check the endorsement language |
Primary and noncontributory wording
Additional insured status alone does not necessarily establish that the subcontractor's policy will pay before the general contractor's own policy or decline to seek contribution. Primary and noncontributory wording addresses priority and contribution between policies. The written subcontract should state the intended requirement, and the endorsement should deliver it.
Waiver of subrogation
A waiver of subrogation is not the same as additional insured status. It addresses an insurer's recovery rights after paying a loss, rather than making the upstream party an insured. Many construction contracts require both additional insured status and a waiver of subrogation.
Match the contract exhibit to actual endorsements
"Can the broker issue a certificate?" is too weak a test. Better questions: do the forms satisfy the owner's exhibit, are the described operations eligible, are completed operations and subcontracted work treated as expected, and what records will be needed at audit and claim time?
How carriers price a general contractor liability policy
Carriers do not price general contractor liability from a single label. "General contracting" is not specific enough. Underwriters ask about the split among new construction, remodeling, residential, and commercial work, the largest project size, which trades the general contractor self-performs, and how subcontractor costs are managed.
Work mix and self-performed trades
A general contractor that subcontracts nearly everything presents a different risk profile from one whose employees perform carpentry, concrete, roofing, or excavation. Disclose all self-performed operations in the application so each carrier can determine the appropriate classification, eligibility, and price.
The application should identify the percentage and types of work instead of relying on a broad description. Ground-up condominium work does not present the same completed operations profile as small commercial tenant improvements.
Revenue, payroll, and subcontractor cost as audit-eligible exposure bases
Some contractor liability policies are auditable. The carrier may set the inception premium based on estimated exposure and then reconcile measures such as gross receipts, payroll, and subcontracted expenses through a premium audit. Which exposure bases apply and how the reconciliation works vary by policy. If actual activity exceeds the estimate, the policy's audit terms may require additional premium.
Budget for growth rather than choosing an artificially low estimate to reduce the deposit. A low estimate creates a larger audit bill later.
Loss history and what changed
Underwriters commonly request currently valued loss runs. A claim-free record is useful, but a prior water, fire, fall, or construction-defect loss can be more understandable when the general contractor documents corrective controls, subcontractor action, training, or contract changes.
Submission details carriers ask for
A focused submission helps carriers price the account accurately and may improve the options available.

When general liability pays and when it does not
Three situations show how the same general liability policy can produce different outcomes depending on the endorsements, exclusions, and whether the work was performed by the general contractor's own crew or a subcontractor.
When an incident or demand occurs, preserve contracts, change orders, daily logs, photos, correspondence, subcontracts, certificates, endorsements, invoices, and the identity of every contractor involved. Prompt notice to the broker or carrier matters because a construction claim can implicate the general contractor's policy, several subcontractor policies, an owner's coverage, and policies from earlier years.

Gaps that a cheaper quote can hide
Two quotes with the same $1 million per occurrence limit can differ on completed operations, residential exclusions, per-project aggregates, and subcontractor provisions. A lower price may mean less coverage.
Missing per-project aggregate
GL policies can differ in how the general aggregate applies. Some policies apply one aggregate across all jobs during the policy period, while others may offer a per-project aggregate by endorsement. Ask each carrier how the aggregate works in the quoted policy, and check whether your contracts require a specific aggregate structure.
Residential or project-type exclusions buried in endorsements
Some policies add endorsements that exclude residential construction, condominium work, exterior insulation and finish systems, or other project types. These exclusions may not appear on the declarations page. They appear in the endorsement schedule. A general contractor that does any residential work should confirm the policy does not exclude it.
Limits that do not match the contract
Some contracts require limits higher than the standard $1 million/$2 million structure. Federal contracts can illustrate this: for cost-reimbursement contracts, FAR 28.307-2 states at least $500,000 per occurrence for bodily injury liability as a minimum, and the contracting officer can require additional coverage and higher limits. Those figures apply to the specific federal contract setting, not all private work. But the principle is the same: read the actual insurance exhibit in the contract before assuming standard limits are enough.
How to compare general contractor liability quotes side by side
Comparing two general contractor liability quotes on price alone can miss material differences in what each policy actually covers. Use this checklist to normalize scope before choosing.
Quote comparison checklist
Limits and aggregate structure: per-occurrence, general aggregate, and products-completed operations aggregate
Ask the carrier how the aggregate applies and whether a per-project aggregate endorsement is available.
Completed operations treatment: is completed operations coverage included, and for how long after project completion?
Ask the carrier whether any endorsement or policy provision limits the duration of completed operations coverage.
Subcontractor provisions: does the policy retain the subcontractor exception to the 'your work' exclusion?
Endorsement availability: can the carrier add additional insured, primary and noncontributory, and waiver of subrogation endorsements?
Confirm the carrier can issue the endorsements your contracts require.
Residential and project-type exclusions: does the policy exclude any work types you perform?
Audit basis and minimum earned premium: what exposure base does the carrier use, and what is the minimum earned premium?
Ask the carrier how the audit works and what happens if actual revenue or payroll differs from the estimate.
Defense treatment: does the carrier pay defense costs inside or outside the limit?
Ask the carrier how defense costs are treated so you can compare the effective limit available for damages.
Deductible or self-insured retention: what is the out-of-pocket amount before the policy pays?
Test each quote against a real contract and real project mix. Can the carrier issue a certificate that satisfies the owner's exhibit? Are the described operations eligible? Are completed operations and subcontracted work treated as expected? What records will be needed at audit and claim time?

Frequently asked questions
How much does general contractor general liability insurance cost?
One broker benchmark puts the annual minimum at $1,600 (about $133 per month) for a general contractor under roughly $215,000 in annual revenue, assuming clean loss history, standard $1 million per occurrence and $2 million aggregate limits, and no unusual subcontractor exposure. That is one published starting point, not a quote for your account. Revenue, work mix, subcontractor cost, loss history, state, and other underwriting details may all affect the price a carrier offers.
What does general liability cover for a general contractor?
General liability (GL) generally covers sums the insured becomes legally obligated to pay for covered third-party bodily injury or property damage, plus defense costs, subject to limits, exclusions, and endorsements. Common examples include a visitor injured by a site condition, neighboring property damaged during operations, or consequential damage alleged after defective work. Employee injuries, vehicle accidents, and professional design errors are generally addressed by separate coverage lines such as workers compensation, commercial auto, and professional liability, but the exact treatment depends on each policy's exclusions, exceptions, and endorsements. First-party physical loss to the project itself generally requires a builders risk policy, though GL may still apply to covered third-party or resulting property damage depending on the policy forms, exclusions, endorsements, and facts of the claim.
Does general liability cover work done by subcontractors?
It depends on the policy form and endorsements. Many standard forms include a subcontractor exception to the 'your work' exclusion, which may preserve coverage for property damage to the general contractor's completed work when a subcontractor performed the faulty portion. Some policies modify or remove that exception. Review the actual endorsements rather than relying on the certificate alone.
What is the difference between CG 20 10 and CG 20 37?
CG 20 10 is an additional insured endorsement associated with ongoing operations. CG 20 37 is associated with completed operations. Many construction contracts require both so the upstream party has additional insured protection during the project and after the work is finished. Form edition matters because older and newer editions do not necessarily grant identical scope.
Why is a certificate of insurance not enough to prove additional insured status?
A certificate of insurance is an administrative snapshot showing policy details at a point in time. It does not amend the policy or create additional insured, completed operations, or primary and noncontributory rights. Those rights depend on the actual endorsements attached to the policy. The hiring party should collect and review the endorsements, not just the certificate.
What happens at a general liability premium audit?
Some contractor liability policies may be auditable. The carrier may set the inception premium based on estimated exposure and then reconcile against actual records after the policy period. Exposure bases vary by policy and carrier and may include gross receipts, payroll, subcontractor cost, or other measures. Whether additional premium is owed depends on the specific policy's audit terms and the difference between estimated and actual exposure. Keeping accurate accounting records helps avoid surprises at audit time.
