The cg2037 endorsement (CG 20 37) provides additional insured coverage for completed operations. It picks up where the CG 20 10 stops. Once a subcontractor finishes work and leaves the project site, the CG 20 10 no longer protects the general contractor. The cg2037 endorsement covers claims that arise after the sub's work is done, including construction defect suits filed years after project completion.

For GCs, the CG 20 37 is the endorsement that protects you during the long tail of construction liability. A leaking roof discovered 3 years after completion, a foundation crack that appears 5 years post-occupancy, or a fire caused by faulty wiring 7 years after the electrician left the site are all completed operations claims.

What Does the CG 20 37 Cover?

The CG 20 37 adds the GC as an additional insured on the sub's CGL policy for "products-completed operations hazard." This means the sub's policy covers the GC for bodily injury or property damage that:

Occurs after the sub's work is completed or abandoned
Arises out of the sub's completed work
Occurs away from premises the sub owns or rents (at the project site)

The coverage applies to the sub's completed operations aggregate limit, which is separate from the general aggregate. Standard CGL policies carry a $2,000,000 products-completed operations aggregate alongside the $2,000,000 general aggregate.

Without the CG 20 37, the GC has no coverage under the sub's policy for post-completion claims. The GC's own CGL policy becomes the sole source of defense and indemnity for claims caused by the sub's defective work.

CG 20 37 vs. CG 20 10: When Each Applies

The dividing line between CG 20 10 (ongoing operations) and CG 20 37 (completed operations) is the moment the sub's work is finished.

Timing	Endorsement	Example
During construction	CG 20 10	Roofer's scaffold falls and injures a pedestrian while roofing is underway
After sub completes and leaves	CG 20 37	Roof leaks 18 months after roofer completes installation
During punch list work	CG 20 10	Electrician causes a shock injury while correcting punch list items
After final acceptance	CG 20 37	Electrical panel overheats and causes fire 4 years after final inspection

The gray area is project closeout. When does "ongoing" become "completed"? Insurance policies define work as completed when:

All work called for in the contract has been completed
All work at the project site has been completed
The work has been put to its intended use

If a sub finishes their scope but is called back for warranty repairs, the warranty work restarts the "ongoing operations" clock for that specific repair visit only. The original completed work remains under the completed operations coverage.

State-by-State Statutes of Repose

The statute of repose determines how long after project completion a claimant can file a construction defect lawsuit. This directly affects how long the GC needs completed operations coverage from subs.

Short Repose States (4-6 Years)

Alabama: 7 years from substantial completion
Arizona: 8 years (but 9 years for actions not discovered)
Connecticut: 7 years
Georgia: 8 years from substantial completion
Idaho: 6 years
Montana: 6 years
Utah: 6 years from occupancy or completion

Medium Repose States (7-10 Years)

California: 10 years for latent defects, 4 years for patent defects
Colorado: 6 years plus 2-year discovery period (effective 8 years)
Florida: 10 years from actual possession, completion, or abandonment
Illinois: 10 years from the act or omission
New Jersey: 10 years
Ohio: 10 years from substantial completion
Texas: 10 years from substantial completion
Washington: 6 years from substantial completion (extended to 12 for certain claims)

Long Repose States (10+ Years)

Maine: 10 years (20 years for governmental entities)
Mississippi: 6 years from written acceptance or occupancy
New York: No statute of repose for construction (statute of limitations applies instead)
Wisconsin: 10 years from substantial completion of the improvement

The statute of repose sets the outer boundary for completed operations exposure. A GC in Florida needs 10 years of completed operations protection from every sub. A GC in Idaho needs 6 years. This difference directly affects how long the CG 20 37 endorsement must remain in force.

Anti-Indemnity Laws and the CG 20 37

Anti-indemnity statutes affect the CG 20 37 the same way they affect the CG 20 10. In restrictive states, the CG 20 37 does not cover the GC's own negligence in contributing to the completed operations claim.

How Anti-Indemnity Impacts Completed Operations Coverage

California: The CG 20 37 covers the GC for completed operations claims caused by the sub's work. But Civil Code 2782 voids coverage for the GC's sole negligence or willful misconduct. If a completed operations claim involves both the sub's defective work and the GC's failure to inspect, coverage may be allocated proportionally.

New York: General Obligations Law 5-322.1 limits additional insured coverage (including completed operations) to the sub's negligence. A construction defect claim where the GC's design coordination contributed to the defect may fall outside the CG 20 37's coverage in New York.

Texas: Insurance Code Chapter 151 limits additional insured coverage to the GC's vicarious liability. Completed operations claims that involve the GC's active involvement in the defective condition may not be covered under the sub's policy.

Illinois: The Construction Contract Indemnification for Negligence Act (740 ILCS 35) voids indemnification provisions where the GC's negligence is involved. Completed operations coverage is subject to this same limitation.

States Where CG 20 37 Functions Broadly

In states without construction-specific anti-indemnity statutes (Alaska, Delaware, Massachusetts, Vermont, and several others), the CG 20 37 provides broad completed operations coverage that extends to claims involving the GC's own negligence, depending on the endorsement edition and policy language.

Regional Differences in Completed Operations Exposure

Geography changes the completed operations risk profile and the importance of the CG 20 37.

Southeast (FL, GA, SC, NC): Hurricane and moisture exposure create long-tail waterproofing and roofing defect claims. The CG 20 37 is non-negotiable for exterior envelope subs in this region. Claims frequently surface 3 to 7 years after completion when water damage accumulates to a visible level.

Northeast (NY, NJ, CT, MA): Freeze-thaw cycles expose masonry and concrete defects. Foundation cracking from improper frost protection appears 2 to 5 years post-completion. Waiver of subrogation endorsements on the CG 20 37 are especially important here because insurers aggressively pursue subrogation on freeze-thaw related structural claims.

Southwest (AZ, NM, NV): Soil movement and expansive clay create foundation defect claims that can surface 5 to 10 years after construction. The CG 20 37 needs to cover the full statute of repose period because soil-related claims develop slowly and are expensive to remediate.

Pacific Northwest (WA, OR): Moisture intrusion in wood-framed construction drives completed operations claims. Washington's condo defect litigation wave between 2005 and 2015 highlighted the need for CG 20 37 endorsements from every sub involved in the building envelope.

Mountain West (CO, UT, MT): Altitude-related material performance issues (UV degradation of roofing, freeze-thaw on concrete) create long-tail defect claims. Colorado's construction defect litigation reform has added notice and cure requirements that interact with completed operations coverage timing.

Practical Tips for Managing CG 20 37 Compliance

Tip 1: Require CG 20 37 for the full statute of repose period. Your subcontract should require the sub to maintain completed operations coverage (and the CG 20 37 endorsement) for the entire statute of repose in the state where the project is located. This means requiring the sub to renew their CGL policy with the CG 20 37 for years after the project ends.

Tip 2: Track sub policy renewals post-completion. This is the hardest part of CG 20 37 compliance. Once the sub finishes work and moves on, they have little incentive to maintain coverage naming the GC as additional insured. Set up a tracking system that follows sub policy renewals for the full repose period.

Tip 3: Consider requiring completed operations tail coverage. Some carriers offer a completed operations tail endorsement that extends coverage for a fixed period (3, 5, or 10 years) beyond policy cancellation. This protects the GC even if the sub drops their coverage or goes out of business.

Tip 4: Use the CG 20 38 as an alternative. The CG 20 38 combines CG 20 10 (ongoing) and CG 20 37 (completed) into a single form. Accepting the CG 20 38 simplifies administration and eliminates the risk of receiving CG 20 10 without CG 20 37.

Tip 5: Coordinate CG 20 37 with indemnification provisions. Your contract's indemnification clause and your CG 20 37 requirement should cover the same time period. A contract with a 10-year indemnification obligation and a CG 20 37 that expires with the sub's annual policy leaves a 9-year gap in protection.

Frequently Asked Questions

Can a sub drop the CG 20 37 after completing their work?

Yes, unless the subcontract requires them to maintain it. Without a contractual obligation, the sub can remove the CG 20 37 at their next policy renewal. The GC has no notification right unless a separate endorsement requires the insurer to notify additional insureds of material changes.

Does the CG 20 37 cover construction defect claims specifically?

The CG 20 37 covers bodily injury and property damage arising from the sub's completed operations. Construction defect claims that result in property damage (water intrusion, structural failure, material deterioration) are covered. Claims for purely economic loss (cost to repair without physical damage) may not be covered, depending on the jurisdiction's interpretation of "property damage."

How much does the CG 20 37 endorsement cost the sub?

The CG 20 37 adds 2 to 8% to the sub's CGL premium, depending on trade classification and claims history. High-risk completed operations trades (roofing, waterproofing, structural concrete) pay toward the upper end. Low-risk trades (interior painting, flooring) pay toward the lower end. The premium applies for each year the endorsement remains in force.

What happens if the sub goes out of business after completing work?

If the sub's CGL policy is cancelled or non-renewed, the CG 20 37 coverage ends. However, if the sub purchased an extended reporting period (tail coverage) before cancellation, the CG 20 37 may continue to provide protection during the tail period. Without tail coverage, the GC loses completed operations protection from the sub's policy when the sub closes.

Is the CG 20 37 required on residential projects?

Contract requirements dictate whether the CG 20 37 is needed, not project type. However, residential projects, particularly multi-family condominiums, carry some of the highest completed operations exposure due to homeowner association litigation patterns. Many residential GCs require the CG 20 37 from all subs as standard practice.

Does the CG 20 37 apply to warranty work?

Warranty work performed after completion creates a temporary return to "ongoing operations" status for that specific work visit. The CG 20 10 would cover claims arising during the warranty repair itself. The CG 20 37 covers claims arising from the original completed work. If the warranty repair creates a new defect that appears later, that new defect falls under completed operations and the CG 20 37 once the warranty repair is finished.
