Hawaii flood insurance and flood history
From FEMA's flood insurance and disaster data · Updated 2026-10-08
FEMA's National Flood Insurance Program (NFIP) data lists 6,285 flood insurance claims in Hawaii since 1978. The NFIP paid $167.9 million on them (building, contents and Increased Cost of Compliance payments, in the dollars of the year paid).
The year with the most claims was 1992, with 1,116, mostly from Hurricane Iniki.
In the last ten years (2017–2026) there were 1,518 claims, and the average paid claim was $71,477.
29% of the claims with a recorded flood zone came from buildings outside FEMA's high-risk zones (rated zones B, C and X).
About 3.9% of homes in Hawaii had an NFIP flood policy in FEMA's latest count (11,829 of 304,141 residential buildings). In the high-risk flood zones (Special Flood Hazard Areas), it was 88% (7,309 of 8,317).
Since 2000, FEMA has made 15 flood-related disaster declarations covering parts of Hawaii. The most recent was DR-4951-HI (Hurricane Lala), declared October 7, 2026.

What flood insurance costs in Hawaii
On June 30, 2026, 63,212 NFIP flood insurance policies were in force in Hawaii. For the 8,730 single-family homes among them, the typical (median) yearly cost was about $1,460; the average was $2,100.
| Rated flood zone | Policies | Typical yearly cost, single-family home | Average cost | Average building coverage |

| Moderate- and low-risk zones (B, C and X) | 11,101 | $1,240 | $1,360 | $241,000 |
Cost here is what FEMA's data lists as the policy cost: the premium plus the reserve fund assessment, federal policy fee and HFIAA surcharge. It covers single-family homes only (not condos, apartments or businesses), with costs rounded to the nearest $10 and shown only where at least 20 homes back the figure. Your own price depends on your building and the coverage you choose; see how flood insurance is priced. Private flood insurance isn't included.

Where these numbers come from
All figures on this page are calculated from FEMA's public OpenFEMA datasets:
- NFIP Redacted Claims (v3) (FEMA (OpenFEMA)): NFIP claims since 1978, downloaded 2026-10-08. Dollar amounts are what the NFIP paid, not adjusted for inflation. Claims filed under private flood insurance aren't included.
- NFIP Residential Penetration Rates (v1) (FEMA (OpenFEMA)): NFIP residential policy contracts in force (as of August 3, 2026) divided by FEMA's count of residential buildings from the National Structure Inventory. FEMA notes that inventory is incomplete in some counties, which can inflate the rate. Private flood policies aren't counted.
- NFIP Redacted Policies (v3) (FEMA (OpenFEMA)): NFIP policies in force on June 30, 2026 (a policy counts if its term covers that date and it wasn't cancelled), downloaded 2026-10-08. Policy counts are FEMA's insured units, so a condominium association policy counts each unit. Costs are FEMA's "policy cost" (premium plus reserve fund assessment, federal policy fee and HFIAA surcharge) for single-family homes only. Policies FEMA's data doesn't place in a county count toward the state only.
- Disaster Declarations Summaries (v2) (FEMA (OpenFEMA)): disaster declarations, downloaded 2026-10-08. We count a declaration as flood-related when FEMA lists flooding (or a dam or levee break) as its incident type or a designated incident type, or the declaration's title mentions flooding.
FEMA's redacted claims data doesn't identify properties, and FEMA notes that some records lack a county or flood zone. See how we use the data.
