GFP Real Estate has locked down more than 43,000 square feet of fresh leases at 520 Eighth Avenue in Midtown Manhattan, filling multiple floors of the 26-story tower with a mix of theater, nonprofit, medical and commercial users. Announced May 19, 2026, the deals range from short to long term and fit neatly into landlords’ broader push to re-tenant Midtown floor plates near major transit hubs. The new signings shuffle occupancy across several levels and bring a roster of well-known arts and advocacy groups alongside newer commercial users.
New leases and tenants
As reported by New York Real Estate Journal, the marquee deal is with The Shubert Organization, which signed an 11-year lease for 14,480 square feet on the 11th floor. The outlet also notes that Stuf Storage committed to a 10-year lease for 7,792 square feet, while The Nation Company took 6,054 square feet on a five-year term.
Other new agreements cited in the report include Dr. James Outpatient Psychiatry, which leased 3,006 square feet, the Afro-Latin Jazz Alliance with 3,810 square feet, law firm Kelman Winston & Vallone PC with 2,695 square feet, and the Joint Retirement Board for Conservative Judaism with 2,625 square feet.
About the building
According to GFP Real Estate, 520 Eighth Avenue was built in 1926 and is a 26-story office tower comprising more than 860,000 square feet. The property sits between West 36th and West 37th streets, close to both Penn Station and the Theater District.
The company’s listing notes that tenants have access to the A, C and E subway lines, the 1, 2 and 3 trains, as well as Amtrak, the Long Island Rail Road and NJ Transit. GFP also highlights a renovated lobby and modernized elevators, features that help keep the nearly century-old property competitive in the current market.
What the deals signal
The tenant mix at 520 Eighth Avenue, which now runs from performing-arts organizations to a storage operator and a medical practice, underscores a broader Midtown strategy in which landlords pitch flexible floor plates to a wide array of users. Commercial Observer has tracked similar activity at the property, including Wow Brand’s 8,200-square-foot lease and large commitments from construction firms, highlighting GFP’s success in filling different types of space near major transit hubs.
Landlord perspective
Matthew Mandell, senior managing director at GFP who represented ownership in most of the transactions, said the property “continues to resonate with a wide range of tenants seeking quality space in a highly accessible Midtown location,” according to New York Real Estate Journal.
The new agreements, which span from five to 11 years, provide the owner with a blend of long-term stability and flexibility in how the space is used as Midtown leasing dynamics continue to evolve.
