New York City has begun public review of a major 100 Gold Street redevelopment that would replace an aging Lower Manhattan government building with nearly 4,000 homes, including about 1,000 permanently affordable, rent-stabilized apartments.
The 100 Gold Street redevelopment is moving into a new phase after Mayor Zohran Mamdani’s administration announced on Sept. 22 that the city is starting the formal public review process. The updated plan adds roughly 300 homes compared with an earlier version of the proposal, according to the Mayor’s Office.
What is planned at 100 Gold Street?
The city-owned property is in Lower Manhattan’s Financial District, near the Brooklyn Bridge. It currently houses several city agencies, including the Department of Housing Preservation and Development, as well as an older adult center operated by Hamilton-Madison House.
Under the updated proposal, the site would be transformed into a mixed-use residential project with several major components:
- Nearly 4,000 mixed-income homes.
- Approximately 1,000 permanently affordable, rent-stabilized apartments.
- A replacement older adult center.
- About 40,000 square feet of public-realm improvements.
- A roughly 40,000-square-foot publicly accessible commercial fitness center with community programming.
- Relocation of city agencies now working from the aging 100 Gold Street building into modern office space.
The Mayor’s Office says the project would use cross-subsidy from the development to avoid a direct city capital cost for the redevelopment. City officials also say proceeds from the site would help pay for relocating the government agencies currently based there.
Mayor Mamdani framed the project as one part of the city’s broader housing strategy, saying, “New York’s housing crisis demands that we build more — and that we use every tool we have to do it.”
The housing count has grown since the earlier proposal
There is an important difference between the latest announcement and earlier project materials. The New York City Economic Development Corporation’s current project page still describes a plan for about 3,700 homes, with at least 25 percent permanently affordable. The Sept. 22 Mayor’s Office announcement says the plan has since expanded to nearly 4,000 homes, including about 1,000 permanently affordable units.
The administration said the roughly 300-unit increase reflects an effort to produce more housing from city-owned land. Because the proposal is still entering environmental and land-use review, the final number of apartments and other project details could change before approval.
How the affordable share would compare with the neighborhood
According to the Mayor’s Office, the roughly 1,000 permanently affordable homes planned at 100 Gold Street would be close to twice the number of permanently affordable homes built in Manhattan Community District 1 during the past decade. That comparison is being used by the administration to emphasize the scale of the proposal.
The project is also part of the administration’s broader “Block by Block” housing agenda. The Mayor’s Office says that plan calls for building 200,000 new affordable homes and preserving another 200,000 over the next decade, backed by a planned $22 billion in affordable-housing capital over five years.
Public review is only beginning
The announcement does not mean construction is ready to start. The city says a scoping hearing is expected next month as part of the environmental review. The project is then expected to enter the Uniform Land Use Review Procedure, commonly known as ULURP, in 2027.
ULURP is New York City’s formal process for reviewing major land-use actions. It includes review by the local community board, the borough president, the City Planning Commission and the City Council, with additional opportunities for public comment.
State Sen. Brian Kavanagh, whose district includes the site and who chairs the state Senate Housing Committee, supported using public land for housing while also stressing that a project of this size requires a full community review process. That review could lead to revisions before a final plan is approved.
An older adult center remains part of the plan
The existing Hamilton-Madison House older adult center at 100 Gold Street is expected to be replaced with a new facility at the redeveloped site. NYCEDC says a temporary location would be provided nearby during construction so services can continue.
That component is significant because the current center has served Lower Manhattan residents for decades. The administration says the new facility is intended to preserve those services while modernizing the space.
Why this matters outside New York City
For readers in Utica and the Mohawk Valley, the 100 Gold Street redevelopment does not directly change local housing supply, zoning or property taxes. It is a New York City land-use proposal. But the project highlights a broader question facing communities across New York: whether underused or aging publicly owned property can be converted into housing while keeping public services in place.
That debate is especially relevant as cities across the state look for ways to add housing without relying only on undeveloped land. The 100 Gold Street proposal offers one example of how a municipality can combine housing, public facilities and commercial space on a government-owned site, though the project’s financing structure and Manhattan real estate market are very different from conditions in Central New York.
What happens next
The next major step is the environmental scoping process, followed by additional review and community input. If the project moves into ULURP in 2027, elected officials and local residents will have further opportunities to weigh in on the proposal.
Readers who want to follow the project can review updates from the NYC Mayor’s Office and the New York City Economic Development Corporation. As the review proceeds, the key questions will be whether the final plan keeps the promised affordable housing, preserves community services and clears the city’s environmental and land-use approval process.
