Summary
Charlotte County's floodplain ordinance triggers full compliance with flood-resistant construction once repair or improvement costs reach fifty percent of a building's pre-damage market value, the same 50-percent threshold that forced elevation decisions across Port Charlotte and Punta Gorda after Hurricane Ian. The county Building Official administers the rule under Charlotte County Code § 3-2-237.
Substantial damage. Damage of any origin sustained by a building or structure whereby the cost of restoring the building or structure to its before-damaged condition would equal or exceed fifty (50) percent of the market value of the building or structure before the damage occurred. [Also defined in FBC, B Section 1612.2.]. Substantial improvement. Any repair, reconstruction, rehabilitation, alteration, addition, or other improvement of a building or structure, the cost of which equals or exceeds fifty (50) percent of the market value of the building or structure before the improvement or repair is started. If the structure has incurred "substantial damage," any repairs are considered substantial improvement regardless of the actual repair work performed.
Full Breakdown
Article XI of the Building Code, adopted by Ord. No. 5). Once a building crosses that line, including any repair after storm damage, the owner must bring the whole structure up to the flood-resistant construction requirements of the Florida Building Code and ASCE 24; partial fixes are not allowed. The floodplain administrator, who is the Charlotte County Building Official, makes that 50-percent finding for every permit application involving repair, alteration, addition, or rehabilitation of a building in a flood hazard area, comparing a licensed appraiser's market-value estimate against the cost of the proposed work (§ 3-2-237(1)-(3)).
3 for Zone V and Coastal A Zone (§ 3-2-288). Any owner who wants to enclose space under an elevated building more than six feet above the highest adjacent grade must record a signed declaration of land restriction, a nonconversion agreement, in the county's official records before a certificate of occupancy issues (§ 3-2-246(5)). The flood insurance study and rate maps behind these determinations date to May 5, 2003, and are on file at Charlotte County Community Development, 18400 Murdock Circle, Port Charlotte.
Violations & Fines
Undertaking flood-hazard-area work without a permit, or without the elevation certifications this article requires, is presumed a violation under Charlotte County Code § 3-2-269 until the owner produces the missing documentation. The floodplain administrator can issue a stop-work order or notice of violation to the owner, an agent, or whoever is performing the work (§ 3-2-270), and anyone who keeps working after being served is subject to the penalties Florida law prescribes for code violations (§ 3-2-271).
