Cape Coral's Land Development Code (LDC) currently restricts true accessory dwelling units (ADUs) to the Residential Estate (RE) zoning district on lots of at least 40,000 square feet. Standard single-family lots (typically 10,000 sq ft in zones such as R1-D) cannot host a separate ADU and are limited to a non-rentable guest house without a full kitchen. Florida Statute 163.31771 encourages but does not mandate municipalities to permit ADUs in single-family zones, leaving Cape Coral's restrictive framework in place pending local code amendments.
An ADU permit application in Cape Coral is submitted to the Department of Community Development and Building Division, which reviews zoning compliance under LDC Article 4 (Zoning Districts) and accessory structure standards under LDC Article 5, Chapter 2 (Accessory Structures). Because most Cape Coral parcels are zoned R1-D, R1-W, or similar single-family categories rather than RE, the practical answer for most homeowners is that an ADU cannot be built; only a guest house without cooking facilities is allowed as an accessory structure. ADUs in RE zones must meet primary-structure setbacks, height limits, FEMA Base Flood Elevation requirements (much of the city is in Zone AE or VE), and the 2023 Florida Building Code 8th Edition wind-load standards for Lee County's coastal high-velocity zone. Sewer and water capacity from Cape Coral Utilities must be confirmed. Septic systems require Florida Department of Health Lee County approval. All accessory structures must be elevated above BFE or use FEMA-compliant hydrostatic vents.
Building or occupying an unpermitted ADU is a code violation under the Cape Coral Code of Ordinances enforceable by the city's Code Compliance Division. Penalties include daily fines (commonly up to $250 per day for first violations and $500 per day for repeat violations under Florida Statute Chapter 162), stop-work orders, mandatory removal of unpermitted structures, and recorded liens against the property. Operating a non-permitted living unit may also forfeit homestead protections and homeowner insurance coverage.
