Key Biscayne is an ultra-low-density, ultra-high-income barrier island south of Miami, and its rental market reflects that: there are no standalone garden-apartment complexes here, only a handful of condo towers and communities where individual owners lease out units. This page covers the developments renters actually encounter when searching for a place on the island.
As of mid-2026, one-bedroom rents on Key Biscayne average well above $2,700/month, with most towers ranging from roughly $3,000 for a modest one-bedroom up to $20,000+ for large waterfront units — among the highest submarkets in all of Florida.

Renters insurance is not optional here. Many Florida leases require it, and standard policies generally do not cover flood damage — that may require separate coverage, even in an apartment. Before signing, look up the building's flood zone on FEMA's flood map service and ask which evacuation zone it sits in.
Ask about the real monthly cost. A recurring theme in public resident feedback is fee stacking: valet trash, common-area electric, mandatory bulk internet, pest control, admin and tech fees. Get the full itemized monthly figure in writing before you apply.
Tour with the AC running and ask about hurricanes. Humidity control is the difference between a fine unit and a moldy one; ask how old the AC is. And ask directly how the building handled the last major storm — communities that performed well say so happily, and reviewers call out the ones that didn't.
