SL Green Realty Corp.

Founded in 1980 by Stephen L. Green, SL Green Realty Corp. is headquartered at One Vanderbilt in Midtown Manhattan and has become Manhattan's largest office landlord. It is a fully integrated real estate investment trust focused on acquiring, developing, and managing New York City commercial properties. As of early 2026, SL Green's portfolio encompassed roughly 55 Manhattan buildings, mainly midtown office towers. In recent years, the company has also expanded into residential rentals. For example, it has opened high-rise rental towers like 7 Dey Street in the Financial District and The Olivia at 315 West 33rd Street near Hudson Yards and Penn Station. These rental buildings offer full-service amenities – including 24/7 doormen, fitness centers and rooftop lounges – along with easy transit access and nearby retail, providing a convenient, modern living experience for tenants.

Outside its rental projects, SL Green's portfolio remains anchored by Manhattan offices and mixed-use towers. For example, One Vanderbilt at 1 Vanderbilt Avenue is a flagship skyscraper directly connected to Grand Central's new transit hall. SL Green emphasizes modern amenities and sustainability in its buildings: many have LEED, WELL or Energy Star certifications to ensure efficient, healthy environments. Overall, the company combines prime locations with high-quality design, amenities and tenant services, aiming to offer a comfortable, convenient and sustainable Manhattan lifestyle.
