Completed operations is the portion of a Commercial General Liability (CGL) policy that covers bodily injury or property damage arising from a contractor's or manufacturer's work after that work has been finished or abandoned. It activates once the job is done — filling the gap left by ongoing-operations coverage. Who this is for: contractors, builders, trade subcontractors, manufacturers, and any business that performs services or installs products at a customer's location.
TL;DR — Key Takeaways
- Completed operations coverage triggers after work ends; ongoing-operations coverage triggers while work is in progress.
- It is built into the standard ISO CGL form (CG 00 01) as the "products-completed operations hazard."
- The products-completed operations aggregate is a separate limit from the general aggregate — typically $2 million on a standard CGL.
- Many project owners, GCs, and lenders require contractors to keep this coverage active for 2–10 years after project completion.
- Without it, a single post-job injury or collapse claim could exceed what your general aggregate would cover.
What Does "Completed Operations" Actually Mean?
Under ISO CGL form language, work is considered "completed" when:
- All contracted work has been finished.
- The contractor has left the job site (even if not every punch-list item is done).
- The part of the work that caused the injury or damage has been put to its intended use by someone other than the contractor.
The critical distinction is timing. If a plumber is still on-site soldering a pipe and a leak occurs, that is an ongoing-operations claim. If the plumber finishes, leaves, and the pipe fails two months later and damages a tenant's property, that is a completed-operations claim.
How Does Completed Operations Fit Into a CGL Policy?
Standard ISO CGL policies include two coverage parts relevant here:
| Coverage Part | When It Applies | Aggregate Limit (Typical Standard) |
|---|---|---|
| Bodily Injury & Property Damage — Ongoing Operations | While work is in progress on a job site | Counts against General Aggregate ($2M) |
| Products-Completed Operations Hazard | After work is done or contractor leaves | Separate Products-Completed Ops Aggregate ($2M) |
| Personal & Advertising Injury | Defamation, copyright, etc. | Counts against General Aggregate ($2M) |
| Each Occurrence Limit | Single event cap (both sections) | $1M per occurrence (typical) |
Because the products-completed operations aggregate is separate, a large ongoing-operations claim does not erode the limits available for a post-job lawsuit. This matters enormously for contractors finishing multi-unit residential or commercial projects with multi-year exposure tails.
Why Contractors Can't Skip It
Completed operations claims are among the costliest in commercial construction. Common triggers include:
- Structural defects discovered after occupancy — a framing subcontractor's work causes a partial collapse eighteen months post-close.
- Electrical or mechanical failures — faulty wiring installed by an electrician causes a fire after the homeowner moves in.
- Slip-and-fall from installed work — a tile floor laid by a flooring contractor becomes a slip hazard due to improper slope; injury occurs after final inspection.
- Roofing leaks — water intrusion causing mold found two years after installation.
In each scenario, the contractor is off-site and the work is "complete." Without completed-operations coverage, there is no CGL coverage at all — the ongoing-operations portion simply does not apply.
Occurrence vs. Claims-Made: Which Policy Form Controls?
Most CGL policies are written on an occurrence basis. This means coverage applies if the injury or damage occurs during the policy period, regardless of when the claim is filed. For completed operations, this is favorable: a pipe failure two years after the work is done is still covered if the policy was in force at the time of the failure.
A minority of contractors carry claims-made CGL forms. On a claims-made form, coverage applies only if the claim is first made during the policy period. If a claims-made policy lapses or is cancelled, a tail endorsement (Extended Reporting Period, or ERP) is critical to preserve completed-operations coverage for past work.
Practical rule: contractors should never cancel a claims-made CGL without purchasing at least a 3-year ERP — or longer if contract requirements mandate it.
How Contracts Set the Tail Requirement
Most construction contracts, subcontract agreements, and project owner requirements specify how long a contractor must carry completed-operations coverage after substantial completion. A typical cascade looks like this:
How to read a completed-operations tail requirement in 5 steps:
- Find the insurance exhibit in your subcontract or owner agreement (often labeled Exhibit B or Schedule of Insurance Requirements).
- Locate the "products-completed operations" line — it will state a dollar limit and a duration (e.g., "maintain for 3 years following substantial completion").
- Check if an additional insured endorsement is required — most GCs and project owners require to be named as additional insured on the completed-operations coverage, not just during ongoing work (ISO CG 20 37 is the standard endorsement for this).
- Verify your policy's aggregate resets annually — if you start a new policy year, the completed-ops aggregate refreshes, which is important for multi-year projects.
- Calendar the tail end date and set a reminder to renew or purchase an ERP before the coverage lapses.
Typical Cost Ranges by Trade
Completed-operations coverage is not priced as a standalone policy — it is part of the CGL premium. However, underwriters rate the products-completed operations hazard separately, and the split between ongoing and completed premiums varies by trade risk profile.
| Trade | Typical Annual CGL Premium (1M/2M limits) | Completed-Ops Portion (Approx.) | Notes |
|---|---|---|---|
| General Contractor — residential | $5,000–$18,000 | 40–60% of total | Highest tail exposure; defect claims common |
| Electrical Contractor | $3,500–$12,000 | 35–55% of total | Fire risk elevates completed-ops rate |
| Plumbing Contractor | $4,000–$14,000 | 40–60% of total | Water damage tail claims frequent |
| HVAC Contractor | $3,000–$11,000 | 30–50% of total | Refrigerant liability also a factor |
| Flooring Installer | $2,500–$8,000 | 25–40% of total | Slip-and-fall exposure post-installation |
| Roofing Contractor | $8,000–$30,000+ | 50–70% of total | Highest completed-ops loading of any trade |

Real-World Illustrative Example
Scenario: Framing Subcontractor, 12-Unit Townhome Project, Mid-Atlantic
A residential framing subcontractor in Virginia completes structural framing on a 12-unit townhome development in October 2024. The GC's contract requires the sub to maintain $1M/$2M CGL with a $2M products-completed operations aggregate and name the GC and developer as additional insureds under ISO CG 20 37 for a period of 5 years post-substantial completion.
In March 2026 — 17 months after the sub left the site — a partial floor collapse injures a tenant. The investigation attributes the failure to improper joist hangers installed by the framing sub. The tenant sues the GC, the developer, and the framing sub for $800,000 in medical expenses, lost wages, and pain and suffering.
Because the framing sub's CGL was in force at the time of the occurrence (March 2026), the completed-operations hazard responds. The $800,000 claim is within the $1M per-occurrence limit and is paid. The GC and developer — named as additional insureds on CG 20 37 — are also defended under the sub's policy. The framing sub's ongoing-operations aggregate is untouched; the claim draws from the separate products-completed operations aggregate.
This is an illustrative scenario. Actual coverage depends on specific policy language, endorsements, and the facts of each claim.
FAQ
What is completed operations coverage in simple terms? It is the part of your commercial general liability insurance that covers injuries or property damage caused by your finished work — after you've left the job site. If a customer trips on a staircase you built six months ago, completed operations coverage responds.
Is completed operations the same as a product liability policy? No, but they share a policy aggregate called the "products-completed operations aggregate." Product liability covers manufacturers and distributors for injuries from physical products. Completed operations covers contractors and service providers for injuries from their finished work. Both hazards are bundled under the same aggregate limit in a standard CGL.
Do I need completed operations coverage if I only do small residential jobs? Yes. Even small jobs carry significant tail exposure. A bathroom remodel with a faulty P-trap can cause mold damage discovered a year later. Most standard CGL policies include completed-operations coverage automatically; confirm it is not excluded on your policy.
How long do I need to keep completed operations coverage after a job ends? This depends on your contracts and state statutes of repose. Contracts commonly require 2–5 years; some public projects or high-rise construction require up to 10 years. Many states have statutes of repose ranging from 6 to 12 years for construction defect claims [verify state for specific statute].
Does completed operations cover faulty workmanship itself? Generally, no. CGL policies cover resulting bodily injury or property damage caused by the faulty work — not the cost to repair the faulty work itself. Repairing the defective staircase is not covered; the medical bills for someone who fell because of the defective staircase are covered. A separate contractor's errors and omissions (professional liability) or a builder's risk policy addresses different exposures.
What is ISO CG 20 37 and why does my GC require it? ISO CG 20 37 is an endorsement titled "Additional Insured — Owners, Lessees or Contractors — Completed Operations." It extends the named additional insured status on a subcontractor's completed-operations coverage to the general contractor or project owner after the sub's work is done. Without it, the GC is an additional insured during ongoing work only.
What happens to completed operations coverage if I cancel my CGL mid-year? On an occurrence-form CGL, completed-operations coverage for work already performed survives cancellation because coverage is triggered by when the injury occurs, not when the policy is in force. Future injuries from that past work would still be covered as long as the policy was in force at the time of injury. On a claims-made form, cancellation without an ERP eliminates coverage for future claims arising from past completed work.
Can I increase my completed-operations aggregate limit? Yes. You can purchase umbrella or excess liability coverage that sits above your CGL limits, including the products-completed operations aggregate. For large projects, many GCs and owners require umbrella limits of $5M–$25M or more. An experienced broker can stack coverage across primary and excess layers.
