What insurance does a general contractor need?
A general contractor sits in the liability chain for every sub on site, so your insurance program is shaped by contract risk more than tool risk.
Carriers price on whether your subs carry proper additional-insured endorsements, how your revenue splits across residential, commercial, and hazardous trades, and how long the completed-operations tail runs on your project mix.
What carriers actually price on
Subcontractor certificate program
GCs do not carry tool risk, they carry contract risk. Carriers price GCs on whether subs carry proof of insurance with the correct additional-insured endorsements and how the master subcontract language shifts loss back to the sub.
Revenue split by project hazard
Single-family remodels underwrite differently from mid-rise commercial or heavy civil work. Carriers look at revenue split across residential, light commercial, and hazardous trade work before setting GL and umbrella rates.
Completed operations claim history
Completed operations responds to claims that surface years after a project closes. Carriers price the tail against state statutes of repose and whether the book leans toward new residential construction, which carries the heaviest defect tail, versus commercial tenant improvement or repair work.
How general contractors work with Coverwatch
01 - GL, umbrella, WC, auto, and bonds structured as one program
01 - Multi-Line Coordination
GL, umbrella, WC, auto, and bonds structured as one program
Coverwatch builds the full GC stack so each policy interlocks: the umbrella schedules over GL, auto, and employers liability without gaps. Sub certificate requirements, wrap-up coordination, and bonding capacity are handled in parallel rather than by separate brokers pulling in different directions.
02 - Standard and specialty markets for every project mix
02 - Carrier Depth for Complex Accounts
Standard and specialty markets for every project mix
A GC running residential remodels underwrites differently from one bidding heavy civil or design-build. Coverwatch submits to 35+ carriers including surplus-lines markets that write adverse loss history, new-venture GCs, and mixed books that standard carriers decline.
03 - Certificate tracking, audit prep, and proactive renewal shopping
03 - Sub Compliance and Renewal Management
Certificate tracking, audit prep, and proactive renewal shopping
Coverwatch tracks sub COIs against your subcontract requirements, flags missing CG 20 10 and CG 20 37 endorsements before mobilization, and prepares payroll documentation for the annual audit. Renewal submissions go out 90 days early so you never sign a subcontract with an expired certificate.
How your general contractor insurance program gets built
Review your project book, sub program, and loss history
Coverwatch reviews loss runs, experience modifier, revenue split by project type, sub prequalification standards, and your bonding needs. Residential remodels, commercial TI, and public work each carry different endorsement requirements, and the submission is built to match the actual book.
Coverage for every general contractor risk
Comprehensive protection tailored to general contractor exposures.
CoreRequired for most operations
General Liability with Completed Operations
Covers third-party injury and property damage from your own work, jobsite premises, and sub operations on active and completed projects.
Workers Compensation (NCCI 5606)
Covers supervisors and executives under class 5606, with field crews rated under their respective trade codes.
Commercial Auto for the Fleet
Insures pickups, service trucks, and equipment haulers, including hired and non-owned auto for supervisors in personal vehicles.
RecommendedCommon across most operations
Umbrella / Excess Liability
Extends underlying GL, auto, and employers liability limits to reach the total required by commercial subcontracts.
Builder's Risk (Project Property)
Covers the structure and materials on an active project against fire, wind, theft, and water before substantial completion.
Surety Bonds (Bid, Performance, Payment)
Guarantees to the project owner that the GC will honor the bid, complete the work, and pay subs and suppliers.
SituationalDepends on your specific operation
Professional Liability for Design-Build
Covers design errors when the GC takes on engineering coordination, performance specs, or value-engineering decisions.
Contractors Pollution Liability
Covers fuel spills, silt runoff, mold, and disturbed contaminated soil that standard GL pollution exclusions deny.
Subcontractor Default Insurance (SDI)
Reimburses the GC for completion costs and delay damages when a prequalified sub defaults on the project.

What general contractor claims actually look like
Real exposures your broker should understand and have a plan for.
Subcontractor injures a third party and the claim lands on the GC
A framer drops material from a scaffold and injures a passerby. The claim names both the sub and the GC. Without CG 20 10 and CG 20 37 on the sub's GL, the GC's own policy pays first and the loss reserve ruins the renewal.
Latent defect surfaces years after project closeout
Water intrusion, foundation cracks, or envelope failures often emerge two to six years after substantial completion. Completed operations must be in force during the year the claim is brought, and the statute of repose in most states runs about ten years.
Active-project fire before substantial completion
A torch-cut spark ignites dunnage stored on the deck. The loss hits builder's risk, not GL. If the contract made the GC responsible for builder's risk and it was never bound, the GC absorbs the direct loss and delay damages.
Commercial auto loss on a fleet driver with a weak MVR
A superintendent with an uncleared at-fault history causes a multi-vehicle accident in a company truck. The carrier audits the driver schedule, surcharges the renewal, and may non-renew if the MVR was not disclosed at binding.
Design-build owner alleges a professional error
A value-engineering substitution on a design-build job underperforms and the owner sues for design negligence. GL responds to physical damage only; professional liability answers the design claim. Without it, the GC funds the defense from cash flow.
Miller Act payment bond claim on a federal project
An unpaid supplier or second-tier sub files suit against the GC's Miller Act payment bond. The surety pays and seeks indemnification from the GC under the general agreement of indemnity. The claim rarely closes without cash collateral posted or bonding capacity frozen.
General Contractor licensing and compliance
The licenses, endorsements, and proofs buyers and regulators want to see before they let you on the job.
- State general contractor license insurance minimums
- Most state contractor licensing boards require proof of general liability (often $500K to $1M per occurrence) and a surety license bond as a condition of issuing or renewing a GC license. Limits, bond amounts, and exempt thresholds vary materially by state and license classification.
- AGC-standard additional insured endorsements on every sub's GL
- The industry-standard subcontract requires each sub to name the GC as an additional insured for ongoing operations (ISO CG 20 10) and completed operations (ISO CG 20 37), on a primary and non-contributory basis. Collecting and verifying certificates of insurance before mobilization is non-negotiable on commercial work.
- Surety bonding capacity for public work
- Federal contracts over the Miller Act threshold require both performance and payment bonds from the prime contractor. Most states impose parallel little Miller Act bond requirements on state and local public projects. Establishing bonding capacity with a T-listed surety is a separate underwriting relationship run in tandem with the P&C placement.

Numbers we watch
General contractors sit in the liability chain for every sub on site, which makes the anchors below unusually load-bearing: federal bond thresholds, NCCI supervisor codes, AGC subcontract limits, ISO endorsement pairs, and the state statute-of-repose tail. These are the numbers owners, sureties, and carriers underwrite the account against.
- Miller Act bond threshold for federal construction contracts
- $150,000
- NCCI class code for GC executive supervision
- 5606
- Typical GL limit required on commercial construction subcontracts
- $1M / $2M
- Additional insured endorsement pair for subs and tiered GCs
- CG 20 10 + CG 20 37
- Completed operations tail alignment
- 10 years
- Builder's risk obligation under standard owner-contractor agreements
- AIA A201
FAR 28.102-1 requires performance and payment bonds on federal construction contracts exceeding $150,000. Contracts between $35,000 and $150,000 allow alternative payment protection, and most states run a parallel little Miller Act on state and municipal work.

Covers Project Manager, Construction Executive, Construction Superintendent, and similar titles in the NCCI Scopes Manual. Applies only to supervisors working through foremen without hands-on labor; field crews rate under their trade class. Misclassified payroll is the most common WC audit finding on GC accounts.

AGC standard subcontracts call for $1M per occurrence and $2M aggregate GL as primary. Commercial and public work regularly require $5M to $10M total, built by stacking an umbrella over the primary.

Ongoing operations plus completed operations additional insured, written primary and non-contributory. Subcontracts that collect only one, or accept a COI without the endorsement pages, leave the GC's GL paying first on sub-origin claims.

Most state statutes of repose cap construction defect suits at roughly ten years after substantial completion. Completed operations must be in force the year the claim is brought, so GL has to be maintained with an unexhausted completed-ops aggregate for at least that long.

AIA A201, ConsensusDocs 200, EJCDC C-700, and DBIA 535 default builder's risk to the owner. Private contracts frequently override that default and make the GC responsible, so every new agreement requires a read of the insurance exhibit before bid.

Common questions
about general contractor insurance
A commercial GC typically carries a one million per occurrence, two million aggregate GL as the primary, with a five million or ten million umbrella stacked on top. Public works bids and larger commercial subcontracts often require the total limit rather than just the primary. The exact number comes from the owner's contract and the bonding language, not a generic industry default, so every new project requires a fresh check against the insurance exhibit.
The GC has three options: refuse the award, accept a waiver that shifts the risk back to the GC's policy (expensive at renewal), or add the sub as a named insured on a project-specific owner or contractor controlled insurance program when one is available. The common failure mode is accepting a certificate of insurance without the CG 20 10 and CG 20 37 endorsement pages, which leaves the GC exposed for the sub's work even though the certificate looked clean at mobilization.
Under AIA, ConsensusDocs, EJCDC, and DBIA standard contracts the owner buys builder's risk because the owner has the largest insurable interest in the unfinished structure. Many private contracts override that default and make the GC responsible. Whoever buys, the GC, the lender, and key subs should all be named insureds, and the contract should be explicit about who carries the deductible on a claim.
An owner-controlled insurance program is bought and administered by the project owner; a contractor-controlled program is sponsored by the GC. Both consolidate GL, excess, and often workers comp for every enrolled party on one large project. Enrolled contractors deduct their own insurance cost from the bid and rely on the wrap-up for project exposures, while continuing to carry practice policies for off-project operations.
Yes, because most construction defect claims surface years after substantial completion. The general liability policy must be in force during the year the claim is brought, with the completed operations extension active and its aggregate limit not eroded by other open claims. The statute of repose in most states caps the exposure window around ten years, which is why completed operations should be maintained for at least that long after the last significant job closes.
The Federal Acquisition Regulation requires performance and payment bonds on federal construction contracts above a stated threshold, with an alternative-payment-protection band for smaller contracts. Most states run a parallel little Miller Act for state and municipal public work, with thresholds and bond penalty amounts set by each state's procurement code. The current federal dollar threshold sits in the information anchors below.
