Is my property in a flood zone?
Every property in the US is in some FEMA flood zone. The question that matters is whether the buildings sit in the special flood hazard area (zones starting with A or V), where lenders on federally backed loans must require flood insurance. Look up the address, then check where each building falls, not just the address pin.
High, moderate, minimal
A and V zones: at least a 1% chance of flooding each year. V zones add wave action on the coast.
Shaded X (or B on older maps): the 0.2% annual-chance area. Unshaded X (or C): minimal hazard. FEMA says 29% of flood insurance claims from 2014 to 2024 came from outside the high-risk areas, so lower risk is not no risk.
If it's in the zone
Expect required flood insurance on a federally backed loan, higher premiums for a lower floor, and local rules on rebuilding after damage. Price those into your offer.
