SL Green Realty Corp.’s 1.5 million-square-foot office tower at 919 Third Avenue in Midtown Manhattan has officially reached 100% occupancy, marking a significant milestone for the New York office market. The achievement follows a major lease expansion by the New York State Office of General Services (OGS), which added 66,100 square feet to its existing space, bringing its total footprint in the building to 117,390 square feet under a new 15-year lease.
The property, one of SL Green’s flagship Midtown assets, is home to several prominent tenants, including Bloomberg LP, which occupies roughly 925,000 square feet after a renewal and expansion completed in recent years. The law firm Schulte Roth & Zabel also maintains a presence in the building, underscoring its reputation as a premier address for corporate and professional tenants.
Beyond its commercial significance, the tower is also known for housing one of New York’s most iconic restaurants, P.J. Clarke’s, located at the corner of East 55th Street. The restaurant, a long-standing Midtown staple, contributes to the building’s lively streetscape and appeal for both tenants and visitors.
The leasing transaction was handled by CBRE, with Stephen B. Siegel and Liz Lash representing the OGS, and Robert Alexander and Ryan Alexander representing SL Green. The full lease-up of 919 Third Avenue comes at a time when many office buildings across Manhattan continue to face challenges with vacancy and shifting tenant demand.
Achieving full occupancy at such a large property signals renewed confidence in Midtown’s office market, especially for well-located, amenity-rich Class A buildings. With stable, long-term tenants like Bloomberg and the State of New York, SL Green has strengthened the asset’s position in a market still adjusting to hybrid work trends. The presence of P.J. Clarke’s and other retail amenities adds another layer of value, reinforcing the role that mixed-use vibrancy plays in driving tenant retention and long-term asset stability.
