For Zone X, a moderate-to-low-risk zone, annual residential flood insurance premiums range from about $140 for $20,000 building and $8,000 contents coverage, to about $455 for $250,000 building and $100,000 contents coverage, as of 2015, states FloodSmart.gov. For Zone AR, a licensed insurance agent must calculate property premiums.
For commercial flood insurance coverage, the annual premiums range from about $650 for $50,000 building and $50,000 contents coverage, to about $4,920 for $500,000 building and $500,000 contents. Up to $300 in surcharges may apply. Policies can cover a building, its contents or both, notes FloodSmart.gov.
Rates for high-risk areas such as Zone AR depend on factors including building construction and elevation. The Zone AR rate is not higher than an unnumbered Zone A rate, if the structure complies with regulations for Zone AR floodplain management, states the Federal Emergency Management Agency. Zone A is the flood insurance rate zone for 1-percent-annual-chance floodplains.
