Definition
FEMA flood maps show which areas the government considers flood-prone based on historical data. These maps determine whether lenders require flood insurance for mortgaged properties. Flood insurance is mandatory if you're in a designated flood zone, and it's not optional—lenders won't fund properties without it.

FEMA flood maps identify special flood hazard areas (SFHA) based on statistical analysis of historical flood data. These maps determine whether flood insurance is required for federally-backed mortgages. Maps are periodically updated as communities improve drainage or experience flooding changes. Property buyers should always review current FEMA flood maps before purchase, as lenders require flood insurance for designated zones.
Pro Tip
Request official FEMA flood determination letters from your lender. These documents are essential for understanding true insurance requirements.
Example
A property outside the FEMA flood plain may not require flood insurance, reducing annual housing costs.
