Occurrence
A single event, or a series of continuous or repeated exposures to substantially the same conditions, that results in property damage or bodily injury. Each occurrence generally triggers a separate deductible and a separate per-occurrence limit on the policy.
An occurrence is a single event, or a series of continuous or repeated exposures to substantially the same conditions, that results in property damage or bodily injury during the policy period. Each occurrence is generally evaluated as its own loss for deductible and per-occurrence limit purposes.
Why Occurrence Matters in Property Claims
The occurrence definition determines how a loss is treated under the policy. A single wind event that tears off shingles across a neighborhood is one occurrence for each property owner, even if the damage spans hours and multiple wind gusts. If a second named storm rolls through two weeks later and causes additional roof damage, that is a second occurrence, with its own deductible and its own claim file. For contractors writing supplements, understanding whether damage came from one occurrence or multiple is critical to how the claim is structured.
Occurrence and Deductibles
Most property insurance deductibles apply per occurrence. That means if a policy has a deductible and two separate storms cause two separate losses, the insured pays the deductible on each claim. This is distinct from an aggregate deductible that caps total out-of-pocket cost for the policy period. On wind, hail, and named-storm deductibles, the per-occurrence structure can meaningfully change the economics of a claim, especially in regions with multiple seasonal events.
Documenting the Occurrence
Accurate documentation of the date and nature of each occurrence supports the claim. Adjusters rely on weather reports, NOAA storm data, photographs with date stamps, and contractor inspection notes to establish the occurrence. If damage from multiple events is commingled, disputes often arise about which event caused which damage, and those disputes are resolved by evidence, not assumption.
Frequently asked questions
A single occurrence is one event, or a series of continuous or repeated exposures to substantially the same condition, that causes damage. A single hailstorm that damages a roof in one afternoon is one occurrence, even if hundreds of line items are eventually claimed. Two separate storms on two different dates are two separate occurrences.
Most property policies apply the deductible per occurrence. If two separate storms cause two separate losses, the policyholder typically pays the deductible twice. This is why adjusters and policyholders document the exact date of loss for each event.
An occurrence-based policy covers events that happen during the policy period, regardless of when the claim is filed. A claims-made policy only covers claims reported during the active policy period. Most homeowners and commercial property policies are occurrence-based.
