On December 10, 2025, FEMA issued a Letter of Final Determination (LFD) for the City and County of Honolulu’s preliminary Flood Insurance Rate Maps (FIRMs). The LFD signifies the start of a six-month period before the maps become effective on June 10, 2026.
Once the revised FIRMs become effective, mandatory flood insurance requirements will apply to property owners with federally-backed loan or mortgage for improved real property located within the Special Flood Hazard Area (SFHA). Additionally, compliance with Revised Ordinances of Honolulu Chapter 21A – Flood Hazard Areas for new construction, substantial improvement, and/or other development within the SFHA is required.
Oʻahu property owners and renters can check if their property is affected by the map revision at: resilientoahu.org/GetFloodReady.
To help the community better understand the map revisions and their implications, the City and County of Honolulu will be hosting several public information events and also participate at the Building Industry Association Home Show in January 2026.
