Hush Street is tracking what’s being built in Manhattan’s East Harlem.

East Harlem’s current building wave rests on two things: the City Council’s 2017 East Harlem rezoning, which upzoned the Park, Lexington, Third and Second Avenue corridors and East 116th Street, and the Second Avenue Subway’s extension to 125th Street, where controlled blasting began this month. The $6.968 billion extension is due in fall 2032.

Around its future terminus, East 125th Street is filling in: a 711-unit tower has passed its halfway mark, the city has approved a 684-unit tower over the new station, and more than 800 apartments are filed on a city parcel nearby. Much of the rest of the pipeline is fully affordable or senior housing on public land, while one market-rate developer has split a long-stalled Park Avenue site into seven 99-unit buildings.

Where DOB records and press reports disagree on heights or unit counts, both are given. A permit is not treated as proof that construction has started.

Latest UpdateThe MTA says controlled blasting at 125th Street and Park Avenue began the week of Oct. 12, 2026. On Sept. 14, the MTA issued the request for qualifications for the final contract, covering systems and station fit-out.

The Long-Promised Extension

The project’s budget is $6.968 billion, including $3.4 billion in federal funding, with full completion expected in fall 2032, according to the governor’s office. The MTA says property acquisition for entrances and ancillary facilities is underway.

JCS bought the eastern part of a former Extell assemblage for $70 million in December 2024, 6sqft reported. A partial stop-work order on the side next to the fire station on Third Avenue in September 2025 has since been resolved; city records show open safety violations from September 2026.

More Than 1,000 Homes and Two Schools

The B-East developer must include an active ground floor under the East 125th Street Points of Agreement, according to YIMBY. The A-Block plans are early and still need land-use review.

Seven 99-Unit Buildings

Keeping each building at 99 apartments stays just under the 100-unit threshold that triggers the 485-x tax incentive’s construction wage requirement, The Real Deal reported. Bistricer bought the site from Durst for about $50 million; earlier owners including Vornado and Continuum had planned towers here that were never built.

Full reconstruction remains planned for East 105th to 107th Streets, Pier 107 and East 117th to 124th Streets, while the 107th to 114th Street stretch is under evaluation and Pier 107 loses its planned restroom, according to Patch.

What We're Watching Next

The next milestones are the award of the subway’s final contract, expected in mid-2027, the MTA’s search for a developer for its 125th Street tower, the B-East developer selection and DOB approval of 1800 Park Avenue’s seven buildings. NYCHA is also renovating several Harlem developments under a $453 million PACT financing closed in December 2025, spanning Central and East Harlem.

Hush Street also tracks Central Harlem to the west and the Upper East Side to the south.
