Single Family Homes for Sale in Key Biscayne — A Local's Guide

Key Biscayne is Miami's island village — past the Rickenbacker tollgate, between two state parks, with a K-8 school and streets where kids bike to the beach. Condo supply is capped by ordinance and the last new building arrived in 2014, so the market trades on genuine scarcity.

Single-family homes in Key Biscayne mean land, privacy and control — no shared walls, no association tower rules, and the ability to renovate or add on where zoning allows. In a market known for a family island village between two state parks, fifteen minutes from Brickell, houses carry the scarcity premium: land is the one thing this coast cannot make more of, and well-located lots underwrite value through every cycle.

Frequently Asked Questions

Do single-family homes in Key Biscayne have HOA fees?

Many don't — outside gated and master-planned communities, houses in Key Biscayne typically carry no association at all. Where an HOA exists, fees are usually modest compared to condo buildings because there's no tower to staff or insure. Each listing on this page shows any association fee.

What does homeowners insurance look like for a Key Biscayne house?

Insurance is a real line item in South Florida and varies with roof age, construction year and flood zone more than with price. Newer roofs and post-2002 construction quote dramatically better. We flag the insurance profile of any house you're considering before you offer.

How do I tour a home in Key Biscayne?

Every listing on this page has an inquiry form that reaches the broker directly — or call +1 786-370-8570. We arrange private showings around your schedule, including video tours for out-of-town buyers, and there is never an obligation.
