FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Lee County, FL.

Zone	What it means	NFIP required?
A	High-risk flood area; 1% annual chance flood, no detailed analysis.	Yes
AE	High-risk; same as A but with established Base Flood Elevations.	Yes
AH	High-risk shallow flooding (1-3 ft), usually ponding.	Yes
AO	High-risk shallow flooding (1-3 ft) with sheet flow on sloping terrain.	Yes
V	High-risk coastal zone subject to wave action (no BFE).	Yes
VE	High-risk coastal zone with wave action and established BFEs.	Yes
X (shaded)	Moderate risk; between the 1% and 0.2% annual chance flood.	Recommended
X	Minimal risk; outside the 0.2% annual chance floodplain.	No

Summary

Any development in a Lee County flood hazard area, filling, grading, subdivision, manufactured homes, pools, even utility work, needs a floodplain development permit from the County Floodplain Administrator before work starts. The rule reaches unincorporated Lee only, and it runs on the FIRM maps effective November 17, 2022, not on guesswork about where water rises.

City-specific rules exist: Fort Myers, and Cape Coral have their own flood zones rules that differ from Lee County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

The provisions of this article apply to all development that is wholly within or partially within any flood hazard area, including, but not limited to, the subdivision of land; filling, grading, and other site improvements and utility installations; construction, alteration, remodeling, enlargement, improvement, replacement, repair, relocation or demolition of buildings, structures, and facilities that are exempt from the Florida Building Code; placement, installation, or replacement of manufactured homes and manufactured buildings; installation or replacement of tanks; placement of recreational vehicles; installation of swimming pools; and any other development.

Full Breakdown

Lee County Land Development Code § 6-401 reaches every development wholly or partly inside a flood hazard area: subdividing land, filling and grading, altering buildings and structures exempt from the Florida Building Code, placing or replacing manufactured homes, installing tanks, parking recreational vehicles, and building swimming pools. Section 6-411 adopts the Flood Insurance Study for Lee County, Florida and Incorporated Areas, effective November 17, 2022, and the accompanying Flood Insurance Rate Maps (FIRM), as the minimum basis for drawing flood hazard area boundaries; those maps and studies sit on file at the Department of Community Development.

Before touching a flood hazard parcel, an owner must file for a floodplain development permit with the Floodplain Administrator under § 6-433, and no permit issues until the applicant satisfies this article and every other applicable code. Depending on what's proposed, the Floodplain Administrator can require a floodplain development permit in addition to a building permit under § 6-434. Section 6-439 layers on outside approvals: a South Florida Water Management District permit, a State Department of Health permit for septic systems, and a Department of Environmental Protection permit for anything seaward of the Coastal Construction Control Line.

Because this is a Land Development Code article, none of it reaches Cape Coral, Fort Myers, Bonita Springs, Sanibel, Fort Myers Beach or Estero; it governs unincorporated Lee County parcels only, so an address inside any of those cities answers to that city's own flood ordinance instead.

Violations & Fines

Building in a flood hazard area without documented lowest-floor elevation or other proof of compliance is presumed a violation under § 6-471 until the owner produces it. The Floodplain Administrator can issue a notice of violation or a stop-work order under § 6-472, and continuing work after that notice is served is a separate offense under § 6-473. The Land Development Code's general penalty, § 1-5(c), sets a fine up to $500 and up to 60 days in jail, with each continuing day a separate offense.

Frequently Asked Questions

Do I need a county permit to fill or grade land in a Lee County flood zone?

Yes. Section 6-433 requires a floodplain development permit from the Floodplain Administrator before any filling, grading, subdivision, or construction wholly or partly inside a flood hazard area, and the permit will not issue until the work satisfies this article and every other applicable code.

What maps define Lee County's flood hazard areas?

The Flood Insurance Study for Lee County, Florida and Incorporated Areas, effective November 17, 2022, and its accompanying Flood Insurance Rate Maps, adopted by § 6-411, are the minimum basis the County uses to draw flood hazard boundaries; they're on file at the Department of Community Development.

Does this floodplain permit rule apply inside Cape Coral or Fort Myers?

No. This is a County Land Development Code article and reaches unincorporated Lee County only. Cape Coral, Fort Myers, Bonita Springs, Sanibel, Fort Myers Beach and Estero are separate municipalities that enforce their own city flood ordinances, so check with the city instead of the County.

What if I build without a floodplain permit or without elevation documentation?

Missing lowest-floor elevation certification is presumed a violation under § 6-471. The Floodplain Administrator can issue a stop-work order or notice of violation under § 6-472, and continuing the work afterward is a separate offense that can draw up to a $500 fine and 60 days in jail.
