Mitigation
Mitigation is the duty of the insured to take reasonable steps to prevent further damage to the property after a covered loss has occurred, and more broadly, any action taken to reduce the severity or likelihood of future losses.
Mitigation operates on two levels in apartment insurance. First, it is a policy condition: after a covered loss occurs, the insured has a contractual duty to protect the property from further damage. Under ISO form CP 00 10, the insured must take reasonable steps to protect the property from further damage by the same or other causes. For apartment owners, this means boarding up broken windows after a storm, tarping a damaged roof, shutting off water to prevent additional flooding, and securing the property against vandalism or theft. The reasonable cost of these emergency measures is covered by the policy.
Second, mitigation in the broader sense refers to proactive measures that reduce the property's risk profile. Installing fire sprinkler systems, upgrading electrical wiring, reinforcing roofs to meet current wind codes, adding sump pumps and backflow preventers, and implementing security systems all constitute mitigation activities. These measures reduce the frequency and severity of future losses, which in turn can lower insurance premiums through credits and improved loss experience.
Apartment owners who fail to mitigate after a loss risk having their claim reduced or denied. If a pipe bursts on the third floor and the owner does not shut off the water supply promptly, allowing water to damage units on the first and second floors, the insurer may argue that the additional damage was avoidable and reduce the claim payment accordingly. Conversely, owners who invest in mitigation before losses occur position themselves for better underwriting treatment, lower deductibles, and access to preferred insurance markets.
