Summary
Fort Lauderdale parcels that sit seaward of the state's coastal construction control line and also fall inside a mapped flood hazard area face a stricter build standard under Code Sec. 14-10(b): the more restrictive of Florida Building Code Section 3109 or Section 1612, or Residential Section R322, plus ASCE 24 for smaller structures. It is the extra layer of elevation and construction rules for the city's most storm-surge-exposed beachfront property.
Sec. 14-10(b): Buildings and structures seaward of the coastal construction control line. If extending, in whole or in part, seaward of the coastal construction control line and also located, in whole or in part, in a flood hazard area:(1)Buildings and structures shall be designed and constructed to comply with the more restrictive applicable requirements of the Florida Building Code, Building Section 3109 and Section 1612 or Florida Building Code, Residential Section R322 as amended from time to time.(2)Minor structures and non-habitable major structures as defined in F.S. § 161.54, shall be designed and constructed to comply with the intent and applicable provisions of this chapter and ASCE 24 as amended from time to time.

Full Breakdown
54, marks the state-set boundary along Florida's beaches most exposed to storm-driven waves and erosion; Fort Lauderdale's chapter 14 floodplain code adds a second, local layer of regulation wherever that line overlaps a mapped flood hazard area. Sec. 14-10(b)(1) requires buildings and structures extending, in whole or in part, seaward of the line and also located in a flood hazard area to meet whichever is more restrictive between the Florida Building Code's coastal construction and flood-load provisions (Sections 3109 and 1612) or the Residential Code's Section R322.
Sec. 54, must still meet ASCE 24's flood-resistant construction standard and the intent of Chapter 14, even though they fall short of a full habitable building. This coastal strip carries an additional state permitting layer on top of the city review: Sec. 141. Because hurricane storm surge and wave action concentrate precisely in this beachfront band, the dual state-and-city review is aimed at the structures most likely to be undermined or destroyed in a storm, distinct from the city-wide base flood elevation standard that Sec. 14-10(a) applies further inland.
Violations & Fines
Sec. 14-9 treats construction in this coastal band that skips the required elevation and construction standards, or lacks lowest-floor documentation, as a presumed Chapter 14 violation; the floodplain administrator can issue a stop-work order, and conviction carries a fine of not more than $250 or imprisonment of not more than 180 days, or both, with each day of continued noncompliance a separate offense, on top of any separate state enforcement for missing the DEP coastal construction control line permit.
