Summary
In unincorporated Sumter County, new homes in mapped flood hazard areas must have their lowest floor elevated to the base flood elevation plus one foot, or the design flood elevation, whichever is higher, under Sumter County Code § 6-72's amendment to Florida Building Code, Residential R322.2.1. Higher standards apply in Coastal A and AO zones.
R322.2.1 Elevation requirements. 1.Buildings and structures in flood hazard areas not designated as Coastal A Zones shall have the lowest floors elevated to or above the base flood elevation plus 1 foot or the design flood elevation, whichever is higher.2.Buildings and structures in flood hazard areas designated as Coastal A Zones shall have the lowest floors elevated to or above the base flood elevation plus 1 foot (305 mm), or to the design flood elevation, whichever is higher.3.In areas of shallow flooding (AO Zones), buildings and structures shall have the lowest floor (including basement) elevated at least as high above the highest adjacent grade as the depth number specified in feet on the FIRM plus 1 foot, or at least 3 feet if a depth number is not specified.4.Basement floors that are below grade on all sides shall be elevated to or above the base flood elevation plus 1 foot or the design flood elevation, whichever is higher. Exception: Enclosed areas below the design flood elevation, including basements whose floors are not below grade on all sides, shall meet the requirements of Section R322.2.2.
Full Breakdown
Sumter County adopted Ordinance No. 1 of the Florida Building Code, Residential, as codified at Sumter County Code § 6-72. The rule sets four elevation standards depending on the flood zone shown on the county's Flood Insurance Rate Map. Outside Coastal A Zones, the lowest floor of a building must sit at or above the base flood elevation plus one foot, or the design flood elevation, whichever is higher. Inside a designated Coastal A Zone, the same one-foot freeboard above base flood elevation, or the design flood elevation, applies.
In AO Zones, where shallow flooding is mapped without a base flood elevation, the lowest floor, including any basement, must clear the highest adjacent grade by the FIRM's depth number plus one foot, or by at least three feet if no depth number is shown. Any basement floor that sits below grade on all sides is held to the same base-flood-elevation-plus-one-foot standard. 2 rather than full elevation. §§ 59-60. 73(5).
Violations & Fines
Sumter County's Building Official reviews and enforces elevation compliance at permitting and inspection; noncompliant plans are rejected and construction below the required elevation cannot receive a certificate of occupancy. Because § 6-72 states no separate penalty, violations of the Florida Building Code amendments fall under the Code's general penalty, Sumter County Code § 1-6: a fine of up to $500, up to 60 days in the county jail, or both, with each day a continuing violation counted as a separate offense.
