Canal Lot Considerations
Cape Coral's 400+ miles of canals create unique ADU challenges:
- Seawall setbacks: Many canal lots require 10+ feet setback from seawall
- FEMA flood zones: Most of Cape Coral is in AE flood zone
- Elevated construction: Required per Florida Building Code in flood zones
- Hurricane-resistant construction required
Flood Zone and Hurricane
Cape Coral faces significant flood and hurricane risks. Hurricane Ian (2022) caused catastrophic flooding. Elevated construction and impact-resistant windows are required by the Florida Building Code.
Permit Process
- Check zoning: Verify via Cape Coral's GIS/zoning portal

- Flood zone check: FEMA flood map — almost all of Cape Coral is AE zone

- Building permit and inspections: Florida Building Code
