Manhattan Offices Tighten as Lower Manhattan Advances 4,000 Homes at 100 Gold Street
Two separate shifts in New York real estate point in the same broad direction. Office space in Manhattan is becoming scarcer, while a large city-owned site in Lower Manhattan has moved a step closer to becoming housing.
Brokerage CBRE reported 2.24 million square feet of Manhattan office leasing in August, a figure 4 percent above the five-year monthly average, according to a report by NYDailyWatch on the CBRE data.
The islandwide availability rate fell to 13.7 percent in August, down 3.3 percentage points from a year earlier, CBRE reported. The availability rate measures space on offer, including space being marketed for lease, rather than only space that is already empty.
August net absorption reached a positive 1.01 million square feet, CBRE said, meaning tenants took more space than they gave back during the month. Year-to-date net absorption reached 7.59 million square feet.
The average asking rent was 80.05 dollars a square foot in August, roughly unchanged from July and 3 percent higher than a year earlier, according to CBRE. Asking rents are the rents landlords seek, not the effective rents tenants ultimately pay after concessions and construction allowances.
The August figures did not describe a uniform recovery across all buildings. Renewals accounted for 832,000 square feet of the month’s leasing, CBRE reported, and sublease availability remained at 2.4 percent, a sign that retention and existing space still shape the market alongside new deals.
Broader third-quarter figures point in a similar direction. Colliers reported 10.06 million square feet of Manhattan leasing since July, while Newmark said Manhattan availability fell to its lowest level since the second quarter of 2020. Brokerages count inventory differently, so their availability figures are not identical.
In Lower Manhattan, the second development concerns housing rather than offices. Mayor Zohran Mamdani announced on September 22 that the city had begun public review of the redevelopment of 100 Gold Street, the New York City Mayor’s Office said.
The city-owned site would become approximately 4,000 new homes, including around 1,000 permanently affordable, rent-stabilized homes, according to the Mayor’s Office. The updated plan adds roughly 300 homes to earlier estimates.
The city selected GFP Real Estate to develop the site after a competitive request for proposals, the Mayor’s Office said. The site now houses city agencies, including the Department of Housing Preservation and Development, which would relocate to modern office space as part of the redevelopment.
The plan also includes a new older adult center to replace the existing facility operated by Hamilton-Madison House, approximately 40,000 square feet of public realm improvements and a 40,000-square-foot publicly accessible commercial fitness center with community programming, according to the city.
The project would use a cross-subsidy model, in which proceeds from market-rate homes help support the affordable homes, so that it could be completed with no funding from the city, the Mayor’s Office said. Mayor Mamdani described the goal as building a city that New Yorkers can afford to call home.
Public review is not final approval. The city said a scoping hearing would begin the formal environmental review process, with the project expected to enter the Uniform Land Use Review Procedure in 2027. The city announcement did not state a completion date, and that timing remains unconfirmed.
Taken together, the two developments show a Manhattan office market with less space on offer and a Lower Manhattan housing proposal still working through the review process that must come before construction can begin.
