Summary
New and substantially improved structures in Minneapolis's Flood Fringe District must be elevated on fill so the lowest floor sits at or above the regulatory flood protection elevation: base flood elevation plus a one-foot freeboard.
All structures, including accessory structures, must be elevated on fill so that the lowest floor, as defined, is at or above the regulatory flood protection elevation. The finished fill elevation for structures must be no lower than one (1) foot below the regulatory flood protection elevation and the fill must extend at the same elevation at least fifteen (15) feet beyond the outside limits of the structure.

Full Breakdown
Minneapolis administers the National Flood Insurance Program through Chapter 535's FP Floodplain Overlay District. In the Flood Fringe District, all structures, including accessory buildings, must be elevated on fill so the lowest floor is at or above the regulatory flood protection elevation (RFPE): defined as at least one foot above the regional (base) flood elevation, plus any rise from floodway encroachments. Finished fill can be no lower than one foot below RFPE and must extend at least fifteen feet beyond the structure's outside limits. The zoning administrator issues floodplain permits and keeps elevation records; building in the Floodway District is far more restricted.
Violations & Fines
Building without a floodplain permit, or below the regulatory flood protection elevation, is a misdemeanor under § 535.1530; the city can also pursue injunctions, corrective-measure orders, and after-the-fact permits.
