Full Breakdown
Under Chapter 103's flood damage prevention standards, new buildings and substantial improvements must elevate the lowest floor, basement included, to or above the base flood elevation shown on the FIRM; nonresidential structures may floodproof instead of elevating. Completion requires certification by a registered engineer or surveyor, or verification by the chief building inspector, that the elevation was met. The code sets the base flood elevation itself as the floor, without an added local freeboard margin above it.
Violations & Fines
Occupying or certifying a structure whose lowest floor sits below the base flood elevation without proper floodproofing documentation is a misdemeanor, and the structure is presumed in violation until compliance is proven.
