Key Marco is the bridge-access private island (historic Horr's Island) of large custom homesites with a community marina and a CDD — not the Cape Marco condo towers.
Key Marco occupies historic Horr's Island on the southeast side of Marco Island (ZIP 34145), reached from San Marco Road between the island proper and Goodland. Official Key Marco CDD pages confirm a Chapter 190 district; FY 2025–2026 non-ad valorem assessment is $1,700 per property (board materials also state $227,800 total across units). CDD meetings have been noticed at 505 Whiskey Creek Drive. The residential product is custom single-family estates on large lots; market-standard planned count is 134 homesites (used as planned_lots). Homes generally do not have private docks at the lot; owners use the community yacht basin. Secondary sources put the marina at about 105 slips for boats roughly 38–45 feet, with a dredged channel out to the Gulf and no bridges to open water. Amenities commonly listed: clubhouse, fitness, tennis/pickleball, pool. Acreage stories (500–546 acres with ~375 acres preserved) are realtor-only and were not entered. Distinct from Cape Marco. Older broker pages citing a $4,800 CDD are stale.
