Full Breakdown
North Port's Unified Land Development Code sets the citywide floor-elevation standard: Appendix A, § A.1.3.I requires the finished floor of every new building to sit above the 100-year (base) flood elevation, plus whatever freeboard the current Florida Building Code adds on top. Accessory structures kept below that line, carports, storage sheds, must still use flood damage-resistant materials and have their mechanical, plumbing and electrical systems raised to the base flood elevation plus one foot (§ 6.5.9.1.B). A floodplain development permit from the Floodplain Administrator, housed in the Building Department, is required before any development in a mapped flood hazard area (§ 6.5.4.1).
Violations & Fines
Building without an approved floodplain development permit, or without documented lowest-floor elevation certification, is presumed a violation subject to stop-work orders and notices of violation from the Floodplain Administrator (§§ 6.5.8.1–6.5.8.2).
