Exceptional opportunity to lease highly visible retail space directly adjacent to the Syosset Long Island Rail Road Station in the heart of downtown Syosset. Syosset Plaza offers unmatched exposure, strong commuter traffic, and rare on-site parking in one of Long Island’s most affluent and supply-constrained retail markets.

The property is anchored by Dunkin’ and surrounded by a strong mix of national and regional retailers including CVS, Planet Fitness, Webster Bank, Flagstar Bank, Domino’s, and Shell. Nearby municipal parking fields with over 1,000 combined spaces further enhance accessibility and convenience for customers and employees.
