Mark Epstein, the brother of financier Jeffrey Epstein, has quietly put a development site in Hudson Square on the market at 515 Greenwich Street, bringing a longtime Manhattan landlord back into a neighborhood that planners and builders have been eyeing for years. The move refocuses attention on a parcel that city records say has sizable development potential under Hudson Square planning assumptions.
As reported by Crain's New York Business, Epstein's firm has listed the Hudson Square property and the address is now showing up in current market offerings. Crain's flagged the site by its street address and cast the listing as a notable entry in the local commercial-real-estate mix, describing the coverage as the first public sign of a formal marketing push for the parcel this spring.
Site and planning history
City planning documents count 515 Greenwich Street among the mapped redevelopment sites in the Hudson Square district, and the city's FEIS tables outline a potential buildout with roughly 188 residential units and about 12,800 square feet of commercial space on the lot. NYC.gov provides the environmental review and supporting tables that frame how this site fits into the broader Hudson Square plan, which in turn shapes what a buyer can propose and what approvals might be required.
Mark Epstein has long held multifamily and mixed-use properties around Manhattan, and reporting by Business Insider has previously walked through his portfolio and deals. That track record helps explain why the listing is drawing attention beyond the usual churn of New York City property sales, since his holdings and past transactions often pop up in coverage of local ownership and transfers.
What developers will watch
Potential buyers will be weighing whether the site makes more sense as a renovation, a conversion, or a ground-up redevelopment that lines up with Hudson Square's planning framework and the current market. The lot's planning backdrop, along with any required environmental review or permits, is likely to factor heavily into both offers and construction timelines.
For now, key deal specifics such as an asking price or the identity of a marketing broker have not surfaced in public records. More details are expected to emerge as offering documents circulate and new filings hit the city, but at this stage the listing mainly signals that a familiar local owner is back in play on a block developers have been circling for years.
