The Florida Supreme Court recently issued a widely reported decision, Sebo v. American Home Assurance Co., which applied the concurrent cause doctrine in ruling that an all-risk homeowner’s insurance policy provides coverage when damage is the result of multiple events—so long as at least one of them is a covered peril. Plaintiff John Sebo purchased a home, which he insured under an all-risk homeowner’s policy written by American Home. As an “all-risk” policy, it provided coverage for damage to property caused by all perils, except those it explicitly excluded. Design defects and faulty construction were among the excluded perils. Within less than two months of buying the house, Mr. Sebo discovered major leaks during rainstorms, which were later found to be the result of design defects and faulty construction. Hurricane Wilma then caused even more damage. When Mr. Sebo sought coverage for damage from the water intrusion, American Home denied most of the claim on the grounds that it was caused by design defects and faulty construction—which were excluded perils. But the Florida Supreme Court found coverage.
