Inside Key Colony
Roughly forty gated acres on the ocean side of Crandon Boulevard belong to Key Colony, the largest condominium community on Key Biscayne. Its four sections — low-rise Botanica plus the Emerald Bay, Tidemark and Ocean Sound towers — share about 1,200 feet of private beach, a dozen tennis courts, several pools and mature tropical grounds laced with paths. The mix of building types puts everything from garden apartments to high-floor ocean views under one umbrella. Families and long-term residents set the tone; this is village life with beach access, not a resort.
On 101–251 Crandon Blvd in Key Biscayne, Key Colony is a residential condominium, holding four sections. We follow this building unit by unit: each line, floor and exposure trades at its own level, so the listings below are sorted by status — available, under contract and recently closed — rather than blended into a single average.
The layouts seen in recent MLS activity run from 1-bedroom plans up to 4-bedroom residences. Shared facilities on record for the building include complex fenced, exercise room, guard at site, pool, tennis court(s) and bar — worth confirming with the association which are covered by the monthly dues and which carry their own fees.

Where Key Colony Sits
Towers to Compare With Key Colony
Comparable Key Biscayne buildings whose current listings overlap the Key Colony price band — worth touring side by side:
Questions Buyers Ask About Key Colony
Which association documents should I review before buying at Key Colony?
Request the current budget, the reserve study, at least a year of board minutes, the rules and regulations, and a written statement of any special assessment that is approved or under discussion. Florida's condo-safety laws now require milestone structural inspections and structural integrity reserve studies for buildings of three or more stories, so ask where Key Colony stands on both.
Does Key Colony allow pets?
Pet policy is set by the Key Colony association and can limit the number, size or type of animals — and a board vote can change it. Get the current rule in writing before you make an offer; we request it as a standard step on every condo purchase we handle.
What leasing rules apply to owners at Key Colony?
Minimum lease length, how many times a year a unit may be leased, tenant approval and any waiting period for new owners are association decisions. If you plan to rent the unit out, verify the current policy first; the rental and leased tabs on this page show the lease activity recorded here.
How do view lines and floor height affect value at Key Colony?
Inside one tower, price follows the stack: exposure, view corridor, floor height and whether the line is a corner unit all matter. Compare closed prices by bedroom count in the market report, then ask us which lines in Key Colony face which direction before you build a shortlist.
Does a unit at Key Colony come with parking?
Parking arrangements differ by building and sometimes by unit — assigned spaces, valet, or spaces conveyed as limited common elements. Confirm how many spaces transfer with the specific residence and whether guest parking or storage costs extra.
How does Gromadzki Real Estate price a unit in Key Colony?
Building first: closings in the same line and bedroom count, then nearby floors, then comparable towers in Key Biscayne. The association's health — reserves, assessments and insurance — gets equal weight, because it shapes the monthly cost of ownership as much as the purchase price does.
What is the street address of Key Colony?
The building's address is 101–251 Crandon Blvd, Key Biscayne, FL 33149 — part of Key Biscayne. The map lower on this page pins its exact location.
Key Colony: Building Notes
Building file: Key Colony, Key Biscayne, Key Biscayne, Florida 33149 (Miami-Dade County).
