The Bend Apartment Envelope Claim

Because this is an occurrence-based CGL, coverage is triggered by property damage occurring during a policy period, not by when the claim is made. The defective flashing was installed and the resulting water damage began in 2019–2020, so the 2019–2020 policy is the primary responder. If damage continued into later policy years, more than one policy may be implicated; in progressive-damage cases many courts apply a continuous or injury-in-fact trigger, and the insurer's own 'other insurance' and prior-insurance provisions govern how the years share.

On late notice, Oregon applies a notice-prejudice rule: an insurer may not deny liability coverage for late notice unless it can show it was actually prejudiced by the delay. The burden sits with the insurer. Fourteen months between receiving a demand letter and forwarding it is a genuine problem, and prejudice would be easy to show if evidence spoiled, witnesses vanished, or settlement opportunities were lost - but the delay alone is not an automatic bar.

A claims-made policy would have analyzed this very differently: the year the claim was made would control, and a reporting deadline would be enforceable on its own terms.

Split the loss by what was damaged:

• $500,000 to tear out and replace the flashing and siding. This is damage to the insured's own work - the defective construction itself. The 'your work' exclusion bars it, because a CGL policy is not a performance bond and does not pay to redo defective work.
• $900,000 for drywall, flooring, and cabinets ruined by the leaks. This is damage to other property, not the insured's work. The exclusion removes coverage only for the insured's own work and does not reach resulting damage to the rest of the structure.

The decisive fact is the subcontractor exception. Under the modern 'your work' exclusion, the exclusion does not apply to work performed on the insured's behalf by a subcontractor. Since a subcontractor installed the flashing and siding, even part of the $500,000 may be restored to coverage - a result that would flip entirely if Northline's own employees had installed it.

Watch the aggregates: a $1 million per-occurrence limit sits against roughly $1.4 million of claimed damage, and completed-operations losses are tracked against their own aggregate.

Generally no. Additional insured status is derivative: it extends the named insured's coverage to another party for liability arising out of the named insured's operations, work, or premises. It does not turn the policy into first-party coverage for the owner's own conduct.

If the owner is sued by a tenant alleging the owner negligently failed to maintain the roof after being told about leaks, that claim arises from the owner's own acts, not Northline's operations, and is outside the additional insured grant. The owner should look to its own general liability policy for that exposure.

Two important nuances. First, most additional insured endorsements are primary and non-contributory for the covered scope, which matters when both the owner's and Northline's policies are in play. Second, the duty to defend is broader than the duty to indemnify: if a complaint contains any allegation potentially within the additional insured scope, the insurer must defend the owner, even if the owner's own negligence ultimately bars indemnity. Mixing up the duty to defend with the duty to pay is the most common error on this fact pattern.
