General Contractor Insurance: Coverage, Cost & Quotes

What insurance a general contractor needs, how carriers price a GC account based on project type, subcontracted cost, and hazard class, and how to compare quotes from carriers that write general contractor work.

By Trades Coverage Editorial Team · Licensed review by Switchboard Risk Technologies Inc. (NPN 22071809) · Updated May 2026

Key Takeaways

General contractors need broader insurance than single-trade contractors because they hold the prime contract, coordinate subcontractors, and control jobsite risk.

A GC program typically includes GL, workers comp, commercial auto, inland marine, umbrella, and sometimes professional liability or pollution coverage
Your GL policy usually does not cover subcontractor work automatically — require every sub to carry their own coverage and name you as additional insured
Carriers price GC accounts on total cost of subcontracted work, hazard class, payroll, claims history, and state — not just employee payroll alone
Many GC accounts are placed in the E&S (surplus lines) market, which is normal for this trade and does not mean you are uninsurable

Coverage a general contractor actually needs

A general contractor's insurance program is wider than most single-trade contractors because the GC holds the prime contract and coordinates every risk on the jobsite. You manage materials, equipment, schedules, and subcontractors. Each of those creates a separate liability.

Progressive describes general contractors as responsible for materials, equipment, and worksite safety, and notes that GCs often have employees or subcontractors working for them — creating multiple liabilities that a single-trade policy does not address.

General liability

General liability is a core policy for GCs. It addresses third-party bodily injury, third-party property damage, personal and advertising injury, and products-completed operations. For a GC, the harder question is not whether you need GL. The harder question is where your GL policy responds to work performed by subcontractors, where additional insured status matters, and where completed operations claims can appear after the job is done.

Contract requirements commonly start at $1,000,000 per occurrence and $2,000,000 or $3,000,000 aggregate. Loyola University's contractor requirements, for example, require $1M per occurrence and $3M aggregate CGL including personal injury, independent contractor's liability, contractual liability, products liability, ongoing and completed operations liability, and property damage liability.

Workers compensation and employer's liability

If you have employees, workers compensation is required by state law in nearly every state. Public and private contracts also require it from contractors and subcontractors. Loyola's requirements include statutory workers compensation limits and $1,000,000 employer's liability.

Workers comp premiums are calculated per $100 of payroll using a class-code rate. Depending on the state, rates may be set by a state fund, filed by individual carriers, or based on loss costs published by a rating bureau such as NCCI. Your experience modification rating (EMR) adjusts the rate up or down based on your claims history relative to other contractors in the same class.

Commercial auto, inland marine, and builders risk

Commercial auto covers trucks, trailers, and other vehicles used for jobsite operations. Contracts often require a $1,000,000 combined single limit including hired and non-owned vehicles.

Inland marine (tools and equipment coverage) protects owned tools, rented equipment, and materials away from your main premises. It does not replace builders risk. Builders risk is project-property coverage tied to the value of work under construction and is commonly required for construction, renovation, or facility improvement projects.

Umbrella, professional liability, and pollution

Umbrella or excess liability adds limits above GL, auto, and employer's liability. Caltrans construction insurance evidence can include general liability and umbrella or excess liability covering operations by or on behalf of the contractor.

Professional liability is relevant when the GC performs design-build, construction management consulting, or value engineering. Pollution liability applies to demolition, sitework, mold, fuel tanks, remediation, or work where the contract specifically requires contractors pollution liability.

GC programs are broader than single-trade programs

A plumber or electrician may carry GL, workers comp, and auto. A general contractor typically needs all of those plus umbrella, inland marine, builders risk for project property, and sometimes professional liability or pollution coverage. The prime contract creates the broader exposure.

Why your GL policy does not automatically cover subcontractor work

General contractor insurance usually does not include subcontractors because they are not permanent employees. If a sub's work damages a project or injures a third party, your policy may not cover it.

This is the most common coverage misunderstanding for GCs. Many assume their GL covers everyone on the jobsite. It does not. A subcontractor's mistake can leave you holding the liability unless you require the right coverage from every sub before they start work.

Your GL does not automatically cover subcontractor work

Progressive states that general contractor insurance usually does not include subcontractors because they are not permanent employees, and that the GC's policy may not cover a subcontractor's work if it damages a project or harms the client. Hiring only insured subcontractors is one way to close this gap.

Project details

Subcontractor insurance requirements GC business: ________________ GC contact: ________________ Contact email: ________________ Project: ________________ Owner or client: ________________ Subcontractor: ________________ Contract date: ________________ Certificate due date: ________________ Purpose: use this checklist before the subcontractor starts work. Limits and endorsements should be matched to the prime contract, owner requirements, and subcontract scope.

Required coverage and limits

Coverage to collect before jobsite access ☐ Commercial general liability: $1,000,000 per occurrence / $3,000,000 aggregate. Coverage should include personal injury, contractual liability, independent contractor's liability, products liability, ongoing and completed operations, and property damage liability when required by contract. ☐ Workers compensation: statutory workers compensation where required. Employers liability: $1,000,000 when required by contract. ☐ Commercial auto: $1,000,000 combined single limit if vehicles are used for the work. Include hired and non-owned autos when required by contract. ☐ Umbrella or excess liability: required when the prime contract, owner, lender, municipality, or project size requires limits above the underlying policies. ☐ Professional liability: $1,000,000 each claim when the subcontractor provides design, engineering, construction management, consulting, value engineering, or other professional services. ☐ Pollution liability: required when the subcontractor's work creates environmental exposure or the contract specifically requires contractor pollution liability. ☐ Builder's risk or project property requirement reviewed when the subcontractor is responsible for work, materials, or property under construction.

Endorsements to request

Endorsements and contract wording to verify ☐ Additional insured for ongoing operations: names the GC and any required owner, lender, architect, or upstream party for covered work in progress. ☐ Additional insured for completed operations: requested separately when the contract requires protection after the subcontractor's work is finished. Ongoing operations and completed operations are not the same request. ☐ Primary and noncontributory wording: confirms the subcontractor's policy is intended to pay first before other applicable policies and without seeking contribution from the GC's or owner's policy when the same loss triggers both. ☐ Waiver of subrogation: confirms the insurer gives up recovery rights against the named party after paying a covered loss, when the policy and contract allow it. ☐ Completed operations coverage: verify it is included for work that can create injury or property damage after completion. Keep evidence for the period required by the contract. ☐ Exclusions, deductibles, and endorsements reviewed: do not rely only on the certificate if the contract requires actual endorsements or policy documents.

Expiration tracking

Policy expiration log Commercial general liability expiration: ______________________________ Workers compensation expiration: ____________________________________ Employers liability expiration: _____________________________________ Commercial auto expiration: ________________________________________ Umbrella or excess expiration: ______________________________________ Professional liability expiration: _________________________________ Pollution liability expiration: _____________________________________ Certificate received date: _________________________________________ Endorsements received date: ________________________________________ Reviewed by: ______________________________________________________ Renewal follow-up date: ____________________________________________ Verification note: a one-time certificate is not enough for the whole project. Track expiration dates, request renewals before policies lapse, and obtain actual endorsements when the contract requires additional insured, completed operations, waiver of subrogation, or primary and noncontributory status.

Start-work approval

Approval before subcontractor starts work ☐ Subcontractor legal name matches the contract and certificate. ☐ Required coverage lines are shown. ☐ Required limits meet or exceed the contract. ☐ Required additional insured parties are named correctly. ☐ Ongoing operations endorsement received when required. ☐ Completed operations endorsement received when required. ☐ Waiver of subrogation received when required. ☐ Primary and noncontributory wording received when required. ☐ Expiration dates are tracked and renewal reminders are set. ☐ Any exclusions, deductibles, or limitations that affect the work have been escalated before jobsite access. Approval: ________________________________ Date: ________________

Next steps

Send this checklist with the subcontract and insurance exhibit before work starts.
Ask for endorsements, not only a certificate, when the contract requires them.
Set renewal reminders at least 30 days before each listed expiration date.
Escalate missing completed operations or additional insured wording before jobsite access.

Subcontractor insurance controls

Require these from every subcontractor before they start work on your jobsite.

Current GL policy with limits meeting your contract requirements

Minimum $1M per occurrence / $2M aggregate is common for commercial projects.

Workers compensation coverage with statutory limits

Required in nearly every state when the sub has employees. Verify the policy is active, not just issued.

Additional insured endorsement naming you and the project owner

The endorsement itself — not just the certificate — is what creates the coverage extension.

Completed operations coverage

Covers claims arising from the sub's finished work. Without it, a defect discovered after project completion may not be covered.

Waiver of subrogation endorsement

Prevents the sub's insurer from recovering against you after paying a claim on the sub's behalf.

Track expiration dates and verify before each project

A one-time COI at the start of the relationship is not enough. Policies lapse, limits change, and endorsements get dropped at renewal.

Alabama's public contract language makes the contractor responsible to the owner for injury or damage resulting from negligent acts or omissions by subcontractors and those directly or indirectly employed by them. This risk allocation is common across public and private contracts. If your sub causes the loss and has no coverage, the claim flows up to you.

What owners and GCs upstream require on your certificate

When you bid a project, the contract insurance section tells you exactly what coverage, limits, and endorsements you must carry. If your policy cannot evidence these requirements on a certificate, you cannot start work.

Typical limits owners require

Loyola University's contractor requirements provide a concrete example. They require $1,000,000 per occurrence and $3,000,000 aggregate CGL, statutory workers compensation with $1,000,000 employer's liability, $1,000,000 combined single limit for auto when vehicles are used, $1,000,000 professional liability when professional services apply, and builder's risk for facility improvement, renovation, and construction projects.

Caltrans requires successful bidders to submit copies of CGL and excess policy or binder documents, including declarations, endorsements, riders, and modifications. Certificates must show other required coverages and disclose deductible amounts and added exclusions.

Additional insured endorsements

An additional insured endorsement extends defined policy protection to another party for claims arising from your work. ISO additional insured endorsements shifted from broader "arising out of" language to "caused, in whole or in part, by" language, with the later wording intended to narrow coverage. The 2013 ISO forms added language stating coverage will not be broader than what the contract requires.

Ongoing operations and completed operations are separate requests. A policy limited to ongoing operations may not protect the additional insured for completed operations injuries. Contracts that require both need CG 20 10 (ongoing operations, a single endorsement that names the additional insured for claims arising from your work while it is being performed) and CG 20 37 (completed operations, which extends that protection to claims arising after the work is finished).

Primary and noncontributory

Primary and noncontributory means your policy must pay first when multiple policies could respond to the same loss, and your insurer cannot seek contribution from the other party's policy. IRMI defines this as contract insurance language that controls the order in which multiple policies triggered by the same loss respond.

Waiver of subrogation

A waiver of subrogation is your insurer's acknowledgment that it has no right to recover against a liable third party after paying a loss on your behalf. Waivers are often agreed to by insurers when the insured has waived its own right of recovery before a loss occurs.

Loyola's requirements show all of these together: policies must contain a waiver of subrogation in favor of the university, name Loyola as additional insured for ongoing and completed operations, and all contractor coverage must be primary without contribution from Loyola.

Request endorsements before you need the certificate

Do not wait until the project owner asks for the COI to request endorsements from your carrier. Blanket additional insured, primary and noncontributory, and waiver of subrogation endorsements can be added to your policy at inception or renewal. Adding them mid-term is possible but takes time and may delay your certificate.

How carriers price a general contractor account

General contractor GL is not priced the same way as a single-trade policy. Filed rate documents show that some GC classes are rated on total cost of subcontracted work rather than employee payroll alone.

That means if you subcontract $2 million of work on a project, the carrier uses that $2 million figure in the rating formula — not just the payroll you pay your own employees.

Hazard classification matters

A separate filed rate document separates general contractor classes by work hazard, including medium hazard services, high hazard services, and some roofing work.

A GC coordinating drywall, tile, or interior finishes is not the same underwriting question as a GC coordinating roofing, structural steel, or demolition. The hazard class assigned to your operation directly affects the rate per unit of exposure.

Why GCs often pay more than single-trade contractors

Progressive states that general contractors and other high-risk professions may need E&S general liability, and that E&S insurance usually costs more than standard-market insurance because E&S carriers support risks standard insurers do not handle.

How completed operations claims can reach you years after the job

Completed operations covers claims that arise after the project is finished. For a GC, the risk is not just your own work. A subcontractor's faulty work can create liability for you years after project completion.

A construction-sector insurance article explains that contractors and subcontractors can face completed operations liability after finished work causes third-party bodily injury or property damage.

Claim

Subcontractor's faulty electrical work causes a fire after project completion

A general contractor completes a commercial tenant improvement project. An electrical subcontractor installs wiring in the ceiling plenum. The project passes inspection and the GC closes out the contract. Fourteen months later, a connection fails and starts a fire in the finished space.

What happened: The fire damages the tenant's buildout, inventory, and adjacent units. The property owner files a claim against the GC for property damage and lost rental income. The GC's CGL policy is implicated because the GC held the prime contract and coordinated the electrical sub's work.

Coverage: If the GC's policy includes completed operations coverage and the sub was required to carry their own GL with completed operations and additional insured status, the GC's carrier and the sub's carrier both have policies that may respond. If the sub had no coverage or let it lapse, the GC's policy may be the only one available.

Based on completed operations liability patterns described in construction insurance guidance

Additional insured endorsement wording also matters here. ISO's shift from "arising out of" to "caused, in whole or in part, by" language was intended to narrow post-project coverage for additional insureds. If your contract requires completed operations additional insured status and your policy uses the narrower wording, coverage may be limited.

The practical takeaway: require completed operations coverage from every subcontractor, verify the endorsement wording matches what your contract demands, and track policy expiration dates so coverage does not lapse before the exposure window closes.

Why many GC accounts are placed in the E&S market

If your quote comes from a surplus lines carrier rather than a standard admitted carrier, that is normal for general contractors. Progressive notes that general contractors often need E&S general liability because they are a higher-risk profession than many standard-market contractor classes.

Standard carriers often decline GC accounts or limit coverage for certain project types — roofing coordination, structural work, high-rise, or accounts with significant subcontractor exposure. E&S carriers specialize in these risks.

What E&S placement means for your policy

Premiums are typically higher than standard-market coverage because E&S carriers accept risks that standard carriers decline
Policy forms may differ from standard ISO forms, so read exclusions carefully
E&S policies are not backed by state guaranty funds, so carrier financial strength matters more
Multiple E&S carriers still compete for GC business — you are not limited to one option

A general contractor quote request often needs more than one carrier review because GL, umbrella, inland marine, professional liability, and pollution coverage may be handled differently by admitted and E&S carriers. Comparing options helps you see which carriers will insure your project types, subcontractor exposure, limits, and required endorsements.

E&S placement is normal for general contractors

Being placed in the surplus lines market does not mean you are uninsurable or that something is wrong with your business. It means your risk profile — project types, subcontractor exposure, hazard class, or requested limits — exceeds what standard carriers are willing to write. E&S carriers compete for this business, and comparing multiple options is how you find the best fit.

Frequently asked questions

Does general contractor insurance cover subcontractors?

Usually not. Your GL policy does not automatically insure subcontractors because they are not permanent employees. If a sub's work damages a project or injures someone, your policy may not respond unless you have required the sub to carry their own GL, workers comp, and additional insured status naming you. Require current certificates and endorsements from every sub before they start work.

What limits do project owners typically require from a general contractor?

Common requirements include $1,000,000 per occurrence and $2,000,000 or $3,000,000 aggregate for general liability, $1,000,000 combined single limit for commercial auto, statutory workers compensation with $1,000,000 employer's liability, and umbrella coverage for larger projects. Loyola University's contractor requirements, for example, require $1M/$3M CGL, $1M auto, and $1M employer's liability.

Why is a general contractor quote higher than a single-trade contractor quote?

GCs coordinate multiple trades, manage subcontractors, and hold the prime contract. Carriers rate some GC classes on total cost of subcontracted work rather than employee payroll alone. Hazard classification also matters — a GC coordinating roofing or structural work pays more than one coordinating interior finishes. Many GC accounts also require E&S placement, which typically costs more than standard-market coverage.

What is the difference between additional insured and waiver of subrogation?

Additional insured status extends defined policy protection to another party for claims arising from your work. Waiver of subrogation is a separate endorsement where your insurer gives up its right to recover from a liable third party after paying a claim on your behalf. Contracts often require both, but they serve different purposes and are added through separate endorsements.

What does primary and noncontributory mean on a contract?

Primary and noncontributory means your policy must pay first when multiple policies could respond to the same loss, and your insurer cannot seek contribution from the other party's policy. Project owners require this so their own insurance is not triggered by claims arising from your work.

Why do many general contractors end up in the E&S market?

General contractors are a higher-risk class than many standard-market trades because they coordinate multiple hazards, manage subcontractors, and hold broader contractual liability. Standard carriers often decline GC accounts or limit coverage for certain project types. E&S carriers specialize in these risks. Being placed in the E&S market is normal for GCs and does not mean you are uninsurable — it means your quote comes from a different pool of carriers that compete for this kind of work.

What should a GC collect from subcontractors before they start work?

Collect a certificate of insurance showing current GL, workers comp, and auto coverage with limits that meet your contract requirements. Also collect the actual additional insured endorsement and waiver of subrogation endorsement — not just the certificate. Track policy expiration dates and verify coverage is active before each project, not just at the start of the relationship.

How does completed operations coverage protect a general contractor?

Completed operations covers claims that arise after the project is finished. A subcontractor's faulty electrical work could cause a fire months or years later, and the resulting property damage claim can implicate the GC's CGL policy. Without completed operations coverage — and without requiring it from your subs — you may face liability for finished work with no policy to respond.
