Question 1

Which condo communities does Key Biscayne have?

Accepted Answer

We've assembled the island's main communities here: the four-section Key Colony village on the ocean, the Ocean Club towers (Club Towers, Lake Tower, Ocean Towers), the bayfront Grand Bay pair alongside the Ritz-Carlton, the beachfront classics — Casa del Mar, Sands, Commodore Club, Island House, Towers of Key Biscayne and Mar Azul — and Oceana, the island's contemporary flagship. Ordinance keeps building heights low, and nothing new has gone up since Oceana in 2014.

Question 2

What's the price range on Key Biscayne condos?

Accepted Answer

The island's scarcity keeps the entry point high. The older beach buildings and Key Colony generally sell between roughly $700K and $2.5M; the Ocean Club and Grand Bay communities run about $1.5M to $5M; and the top of the market — Oceana and the Ritz-Carlton residences — starts near $3M and passes $15M for oceanfront penthouses. Live pricing for each building is on this page.

Question 3

What is Key Colony?

Accepted Answer

It's the island's oceanfront village: 40 gated acres spread across 1,200 feet of beach in four sections — Botanica's garden low-rises, the Emerald Bay and Tidemark towers, and Ocean Sound. With twelve tennis courts, pools and cafes, it operates on its own. The MLS files the sections under legal numbers (Key Colony No. 1, 2, 4); our pages convert those into the names buyers recognize, and the Key Colony page brings the full community together.

Question 4

Does Key Biscayne suit families?

Accepted Answer

It's Miami's quintessential family island. The village has its own K-8 school with MAST Academy just over the causeway, quiet low-speed streets where kids ride bikes to the beach, and two state parks framing it — Crandon's beaches and golf to the north, Bill Baggs and the lighthouse to the south. A lot of condo buyers here are swapping a Gables or Grove house for lock-and-leave island living.

Question 5

How long is the trip from Key Biscayne to Downtown Miami?

Accepted Answer

Roughly 15 minutes across the Rickenbacker Causeway — near enough for a daily Brickell commute, yet far enough that the island holds onto its own weather, pace and parking. The causeway doubles as Miami's favorite route for cyclists and runners, serving in effect as the island's front porch.

Question 6

Do Key Biscayne condos sit on the beach?

Accepted Answer

On the ocean side — Key Colony, Oceana, Casa del Mar, the Sands, Commodore Club and the Towers — buildings front the Atlantic directly. The Grand Bay pair and the Ritz-Carlton look out over the open bay and the resort's grounds. Nowhere on the island is more than a few blocks from either the sand or the bay.

Question 7

Can you rent out a Key Biscayne condo?

Accepted Answer

Most buildings allow annual leases once the association approves, and a few of the classics still permit seasonal stays; the Ritz-Carlton runs a hotel rental program for eligible residences. The village keeps a tight rein on short-term rentals. Confirm a specific building's current policy before you buy with renting in mind.

Question 8

Is Key Biscayne a sound investment?

Accepted Answer

The island is a scarcity market through and through: village ordinances cap height and density, the newest building arrived in 2014, and demand runs generational, with families holding for decades. The result is steady appreciation and low volatility rather than the swings traders chase. The market report below shows where the numbers stand.
