There is a cruel irony in property insurance: some of the perils most capable of destroying a home or business, flood and earthquake, are precisely the ones standard policies exclude. Understanding that gap, and closing it where the exposure is real, is one of the more consequential coverage decisions a property owner makes.
Homeowners and most commercial property policies typically exclude flood and earthquake damage. That means a property owner who assumes they are covered for water or seismic events may have no coverage at all when one strikes. In flood-prone regions, this is not a remote technicality; it is the difference between recovery and ruin after a predictable event.
Flood coverage is often obtained through a dedicated program or specialty insurer, with its own definitions of what counts as flood, and earthquake coverage is a separate policy or endorsement with its own, often high, deductible. Because these perils are geographically concentrated, availability and price vary sharply by location, and some exposed properties require specialized markets to insure at all.
The right question is not whether a policy technically could cover a catastrophe, but whether the property's actual geographic risk warrants dedicated coverage, which for many coastal, low-lying, or seismically active locations, it clearly does. Reviewing the specific hazards of a property, rather than assuming the base policy handles them, is the essential step.
The big peril is often the excluded one.
