Building Fees & Assessments

Key Colony No. 4 is 45+ 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.
