Key Colony IV, marketed as Botanica, is a 12-story, 1981-built oceanfront tower on Key Biscayne, part of the larger Key Colony complex spanning more than 40 acres of beachfront on this exclusive barrier island. Residents share a private Botanica pool plus access to the complex's oceanfront pool and 12 tennis courts, along with deeded beach access. Key Biscayne itself is a low-density, family-oriented island village connected to the mainland by the Rickenbacker Causeway, prized for its uncrowded beaches, top-rated schools, and a roughly 15-minute drive to Brickell and Coconut Grove.

Florida condominiums of this age are subject to milestone inspection and structural reserve requirements. Our Intelligence Report covers what official city and county records show for this building, and what remains for a buyer to verify with the association.
When you buy into a condo building that's 15 or more years old — anywhere in the US — you should expect by default that an assessment, or several, is in effect or on the way: roof repairs, elevator replacement, repaving, facade work. Buildings age on a schedule, and the bill lands on the owners: often hundreds of dollars a month on top of your mortgage, HOA fee, taxes, and insurance. The unit listing rarely mentions any of it.
In Florida, the stakes for older buildings are higher still. Since the 2021 Surfside tragedy, state law requires milestone structural inspections at 30 years (25 in some coastal areas), Structural Integrity Reserve Studies, and — critically — bars associations from waiving reserve funding for structural components, ending decades of artificially low fees. Add the state's insurance surge, and many older buildings carry obligations that never appear in a listing. None of this makes an older building a bad purchase — but the difference between a well-run 1970s tower and a struggling one can be tens of thousands of dollars per unit. That's the question our building intelligence answers.
