Flood guide

What is the difference between a FEMA flood zone and flood insurance?

A FEMA flood zone is a mapped hazard classification. Flood insurance is a policy decision and often a lender requirement in the Special Flood Hazard Area. Zone labels inform risk—they do not automatically buy or cancel insurance.

Mapped zone first

Check the effective Flood Insurance Rate Map / NFHL for the structure location. Letters of Map Change can alter the result.

Insurance second

Lenders commonly require insurance for buildings in the SFHA securing federally related loans. Outside the SFHA, insurance may still be wise.

Local rules

Communities in the NFIP adopt floodplain ordinances that can require elevation even when insurance is optional.
