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) | 146 | $530–$1,050 | $740 |

Zones are the flood zone each policy is rated in. OpenFEMA NFIP Redacted Policies v3, as of Sep 2026.
