12790 Overseas Highway is a rare, prime commercial opportunity located in the heart of Marathon, Florida, along the Overseas Highway (US-1), the sole arterial connecting the Florida Keys. The 1.24-acre property features direct highway frontage, waterfront access, and a fully approved drive-thru entitlement—an exceptionally scarce combination in the Florida Keys due to strict zoning and environmental constraints. The site includes an existing 1,372 SF building (1981) and offers flexible transaction structures including purchase, lease, ground lease, or build-to-suit, appealing to investors, developers, and owner-users seeking long-term value in a highly supply-constrained coastal market.
The subject site encompasses approximately 1.24 acres with direct frontage along Overseas Highway (US-1), which carries approximately 23,000 AADT, ensuring exceptional visibility and exposure to both local and tourist traffic. The parcel also provides waterfront access with seven dock slips, offering unique ancillary income potential and enhanced utility rarely found in retail-oriented properties. The lot is well positioned for high-demand commercial uses and benefits from Marathon’s central location between Key Largo and Key West.
