FEMA flood zone rules in Chicago, IL — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Chicago participates in the National Flood Insurance Program (NFIP) and regulates construction in FEMA-designated Special Flood Hazard Areas. The city's floodplain management ordinance establishes construction standards above base flood elevation.
Chicago's floodplain regulations require that new construction in FEMA-designated Special Flood Hazard Areas (Zone A and Zone AE) be elevated above the base flood elevation (BFE). The Department of Buildings reviews permits for flood zone compliance. The Metropolitan Water Reclamation District of Greater Chicago (MWRD) also regulates floodplain development in the region. Chicago's stormwater management ordinance (MCC 11-18) complements flood regulations by requiring on-site stormwater management. Flood insurance is required for properties with federally backed mortgages in designated flood zones. FEMA Flood Insurance Rate Maps (FIRMs) identify flood-prone areas, particularly along the Chicago River, North Shore Channel, and some lakefront areas.
Construction in flood zones without proper permits or elevation certificates may result in permit revocation, fines, and loss of NFIP eligibility for the community. Property owners face mandatory flood insurance requirements.
