Penthouses for Sale in Bay Harbor Islands, Florida

Bay Harbor Islands is the low-rise town on two islands in Biscayne Bay, a bridge away from Bal Harbour Shops. Height-capped streets mix mid-century co-ops with South Florida's densest wave of boutique bayfront new construction, much of it with private dockage, and the K-8 school is a genuine draw.

A penthouse in Bay Harbor Islands is a different asset from the tower beneath it: the top floors carry higher ceilings, wraparound terraces, private elevators and often the only floor plans in the building that live like houses in the sky. Known for boutique bayfront buildings and an A-rated school, a bridge from Bal Harbour, Bay Harbor Islands prices its penthouse lines on scarcity — a tower releases only a handful, and the true trophy units trade quietly and rarely. Every listing below is a genuine top-floor residence, identified by the building's own PH designation rather than a marketing label.
