General Liability for General Contractors

General contractors need commercial general liability (CGL) insurance to cover third-party bodily injury, property damage, and completed operations claims arising from construction activities. Most GC contracts and state licensing boards require minimum limits of $1 million per occurrence / $2 million aggregate. Annual premiums typically range from $4,000 to $30,000 depending on revenue, trade, and project type.

Who this is for: Licensed general contractors — residential, commercial, or mixed — who need to satisfy contract requirements, protect against jobsite claims, and stay compliant with licensing rules.

TL;DR — Key Takeaways

• A standard CGL policy for GCs covers jobsite bodily injury, third-party property damage, personal/advertising injury, and completed operations liability.
• Minimum limits demanded by most owners and GCs are $1M per occurrence / $2M aggregate; larger commercial projects often require $2M/$4M.
• Completed operations coverage — claims arising after the project is finished — is the single most expensive GL exposure for GCs and must be verified on every policy.
• Residential new construction typically costs 30–60% more to insure than light commercial work because of higher completed operations and structural defect risk.
• A CGL policy does not replace workers' compensation, commercial auto, professional liability, or inland marine (tools/equipment) coverage.

What Does General Liability Cover for a General Contractor?

A standard ISO CGL policy (occurrence form) provides three coverage parts most relevant to GCs:

Key policy mechanics GCs must understand:

• Occurrence form vs. claims-made: Nearly all GC GL policies are written on an occurrence form — meaning coverage applies to incidents that happen during the policy period, regardless of when the claim is reported. This matters for completed operations exposure that can surface years later.
• Per-occurrence vs. aggregate limits: The per-occurrence limit caps any single claim; the aggregate caps all claims in the policy year. Completed operations often shares the general aggregate or carries its own separate aggregate — confirm which applies.
• Additional insured endorsements: Most owner, GC, and lender contracts require you to add them as additional insureds (AI) on a primary and noncontributory basis. Verify your policy form includes ISO CG 20 10 and CG 20 37 (ongoing and completed operations AI endorsements), or a blanket AI form.

How Much Does General Contractors GL Insurance Cost?

Premiums are primarily rated on payroll or gross receipts (audit basis), with rates varying by trade classification, project type, and loss history.

Ranges are illustrative estimates based on industry benchmarks as of mid-2026; your actual premium depends on carrier, state, classification, and loss history.

Key rating factors:

1. Trade classification (ISO GL class code): Framing, roofing, and excavation carry higher rates than finish carpentry or tile work.
2. Residential vs. commercial: Residential new construction is rated as higher-risk due to structural defect exposure.
3. Completed operations split: Some carriers break out a separate completed operations premium — this can be a significant portion of total cost for home builders.
4. Loss history: A clean 3-5 year loss run can reduce premiums 10–25%; prior GL claims, especially completed operations, may trigger exclusions or sharp surcharges.
5. Subcontractor controls: Policies often include a subcontractor warranty requiring subs to carry their own GL and name you as additional insured. Violations can void coverage for sub-caused claims.

What General Liability Does NOT Cover for GCs

Understanding exclusions is as important as understanding coverage:

Note on the "your work" exclusion: ISO CGL excludes damage to work performed by the named insured. Damage to work performed by a subcontractor is typically covered under the subcontractor exception. Structuring contracts so subcontractors self-perform and carry their own GL is a standard risk management technique.

How to Get GL Coverage as a General Contractor — 6 Steps

1. Gather your business profile: Prior 3 years of loss runs, current payroll by trade classification, gross receipts, and a list of project types and states you operate in.
2. Identify your contract requirements: Collect AI endorsement language, minimum limits, and waiver of subrogation requirements from your typical owner contracts before you shop — these drive the policy form you need.
3. Choose an independent broker: An independent agency can access multiple admitted and surplus lines carriers, which matters for residential new construction and high-hazard trades that standard markets may decline.
4. Review the quote carefully: Confirm limits structure, whether completed operations shares the general aggregate or has its own, AI endorsement forms, and any subcontractor warranty language.
5. Issue certificates (COIs) as needed: Your broker should be able to issue ACORD 25 certificates same-day or next day. Delays cost you project starts.
6. Prepare for the audit: CGL is typically audit-rated — at policy expiration, the carrier audits your actual payroll or receipts and adjusts premium up or down. Budget accordingly and keep clean payroll records.

Real-World Scenario: Completed Operations Claim on a Texas Residential Project

The following is an illustrative example, not a guarantee of coverage or outcome.

A mid-size Texas GC completes a custom home in May 2024 and closes out the project. In January 2026 — 20 months after completion — the homeowner discovers significant water intrusion behind the exterior cladding, attributed to improper flashing installation by a framing subcontractor. The homeowner files a claim for $185,000 in remediation costs.

The GC's CGL policy (occurrence form, $1M/$2M limits, with a separate $2M products-completed operations aggregate) responds because: - The occurrence (faulty installation) happened during the policy period (2024 policy year). - The work was performed by a subcontractor, so the "your work" exclusion's subcontractor exception applies. - The homeowner is a third party.

The carrier pays $162,000 after the $10,000 SIR (self-insured retention) and a negotiated settlement. Because the GC maintained completed operations coverage with its own aggregate, the general aggregate was untouched for any ongoing operations claims that year.

What could have gone wrong: If the GC had purchased a GL policy that lumped completed operations into the general aggregate and had already used $500K of aggregate on prior claims, only $1.5M would have remained — potentially leaving the GC underinsured on a large project.

Frequently Asked Questions

What GL limits do general contractors actually need? Most subcontracts and owner agreements require $1 million per occurrence / $2 million aggregate as a floor. Commercial projects over $5 million in contract value, public work, and federal projects commonly require $2M/$4M or higher. Always verify the specific contract before binding.

Does my GL cover my subcontractors' mistakes? Yes — if the sub's work causes third-party bodily injury or property damage and you are named in the claim, your CGL typically responds under the subcontractor exception to the "your work" exclusion. However, your policy may include a subcontractor warranty requiring subs to carry their own GL; if a sub is uninsured, some carriers can exclude or subrogate against that sub's portion. Requiring certificates from all subs is both a contractual best practice and a policy compliance issue.

Is general liability the same as builder's risk? No. GL covers third-party bodily injury and property damage caused by your operations. Builder's risk is first-party property insurance that covers the structure under construction against fire, theft, vandalism, and certain weather perils. Most commercial contracts require both.

How does additional insured status work for a GC? When you add a project owner or upstream GC as an additional insured (AI), they gain rights to make claims under your policy for liability arising from your work. The AI endorsement form matters: ISO CG 20 10 covers ongoing operations; CG 20 37 covers completed operations. Many contracts require both. "Primary and noncontributory" language means your policy pays first, before the AI's own insurance.

Will my GL cover a slip-and-fall on the jobsite? Yes, for third parties (owners, visitors, inspectors). Your own employees are covered under workers' compensation, not GL. Trespassers occupy a middle ground — you may still face premises liability exposure depending on state law.

What is a waiver of subrogation and why do owners require it? A waiver of subrogation prevents your insurer from suing the named third party (e.g., the owner) to recover claims it paid on your behalf. Owners require it so they are not later sued by your carrier. Most standard CGL policies allow blanket waivers of subrogation via endorsement when required by contract.

How does GL interact with workers' comp for a sole proprietor GC? GL covers third-party claims; workers' comp covers your own injuries as an employee. Sole proprietors are often excluded from their own WC policy by default in most states. If you are injured on a jobsite, your only recourse may be personal health insurance unless you elect to include yourself in a WC policy [verify by state].

What is XCU and does my GL policy cover it? XCU stands for explosion, collapse, and underground property damage — hazards common in excavation, blasting, and utility work. Many standard GL policies include XCU exclusions for these operations. If your work involves excavation near underground utilities or any blasting, confirm that XCU coverage is included or buy it back via endorsement.
