Emerald Bay at Key Colony is a roughly 12-story condominium at 151 Crandon Blvd. Completed in 1980. MLS records most often show about 12 stories.
Key Biscayne is an island village reached by the Rickenbacker Causeway, with Crandon Park to the north and Bill Baggs Cape Florida State Park to the south. Because the building dates to 1980, review the association’s reserves, assessments and milestone-inspection status before you buy.
MLS listings for Emerald Bay at Key Colony have shown a median association fee around $1.29/sqft/month -- shown per square foot, not as a flat dollar figure, since that's comparable across unit sizes rather than skewed by whichever units happen to be listed right now. This is a point-in-time reference, not a live figure, and can change over time. Confirm the current fee for a specific unit before making an offer.
Emerald Bay at Key Colony is 46+ years old, which puts it within Florida's Milestone Inspection requirement (SB 4-D, post-Surfside law covering condo/co-op buildings 3+ stories, coastal buildings inspected at 25 years and every 10 years after). Request the building's most recent milestone inspection report, structural integrity reserve study (SIRS), and reserve fund status before purchasing -- these determine whether a special assessment is likely.
Specific reserve fund balances, pending special assessments, and financial statements aren't public MLS data -- request them directly from the condo association or your agent before making an offer.
