What flood insurance costs in Marion County
What NFIP policyholders in Marion County pay a year for a single-family home, by flood zone: the middle half of premiums on policies that took effect Sep 2025–Sep 2026. It is what insured homes here pay, not a quote for any one building.
| Flood zone | Policies | Middle half | Full-risk median |
|---|---|---|---|
| A zones (special flood hazard area) | 62 | $610–$1,480 | $1,260 |
| X zone (outside the mapped flood zone) | 15 | $720–$1,010 | $1,290 |
Full-risk premium: the median of FEMA's own full-risk premium for the same policies (Risk Rating 2.0). A discounted policy rises toward it a step each year, within the law's cap on yearly increases. Zones are the flood zone each policy is rated in. OpenFEMA NFIP Redacted Policies v3, as of Sep 2026.
