Flood maps and October 2026 filing requirements in Palm Beach County

Use the County promoted Forerunner lookup and FEMA effective flood maps for the exact site, then obtain an official determination through the local floodplain reviewer and appropriate licensed professional before purchase or construction. A map result is not a construction approval or a statement of no flood risk. County Building announced a Flood Legend requirement effective October 1, 2026 for permit submissions for new construction, substantial improvements and standalone equipment installations, and an approved MEP equipment elevation certificate for applicable standalone equipment. Use the current guideline and form in County submissions; confirm city requirements for municipal property. Prior approvals, map changes, elevations and substantial improvement review can affect the filing.
