463 Greenwich Street

Six stories across a 175-foot frontage: horizontal loft space, not a tower stack. Apartments run full-floor and part-floor within the six original warehouse sections, which is why unit designations mix plain floor numbers with directional halves and a penthouse. Filings describe the stock plainly — mezzanines cut into double-height volumes, new skylights and roof bulkheads, convenience stairs between floors, private roof terraces above, a common roof deck. Windows are the original industrial pattern, many six-over-six. The stepped cast-iron-framed sidewalk vault survives in altered form on Desbrosses and the southern Greenwich frontage. Because the building sits in a historic district, exterior work — windows, storefronts, anything visible at roof level — requires LPC review, a real cost and schedule item on any envelope renovation.

The cooperative owns the fee, the residential floors and the commercial base, so retail income accrues to the corporation rather than to a third-party condominium owner; evaluate net rental income, expenses, vacancies and the acquisition financing in the current financials. The recorded refinancing occurred in 2021, but current debt affordability is not established by that amount alone. Staffing, service level and reserves are matters for the current statements and the managing agent; we obtain them for clients at offer stage rather than characterizing them from public data.

The residential conversion predates DOB's online filing record, so the alteration job that created the dwelling use is not retrievable from open data — it will be in the offering plan. What the record does show is a building settled into residential use by the late 1990s and continuously worked on since: renovations to an "existing loft dwelling" and, in one 2006 filing, an "Old Code Loft Dwelling"; mezzanines, skylights and bulkheads cut into individual lofts; combinations in 2010, 2013 and 2015; a roof deck built 2012 and extended 2016; and a 2014 alteration converting a remaining office to a loft dwelling.

No joint living-work quarters for artists designation appears in the occupancy record. Filings classify the residential occupancy as J-2 under the old code and R-2 under the 2008 code, with no JLWQA restriction. Interim Multiple Dwelling status under Article 7-C could not be confirmed or ruled out — the Loft Board's registration file is not published as open data, and nothing in the DOB, DOF or ACRIS record indicates Loft Board coverage. Ask the managing agent.

The ownership structure is the more consequential story. Until 2021 the property was a two-unit condominium: a commercial unit and a residential unit, the latter owned by the cooperative. In December 2020 the cooperative bought the commercial unit outright from a private holding company for $4 million, with the shareholders joining in the conveyance, and in 2021 filed with DOB to merge the two condominium tax lots back into the base lot. The condominium regime is gone; the co-op owns the whole building and its retail rent roll. It consolidated its underlying financing in November 2021 into roughly a $2.7 million first mortgage plus a $500,000 line. These are historical recorded amounts, not a current balance or a measure of debt affordability; review present debt service, maturity, reserves and the budget.

One live diligence item. DOF's historical J-51 file records a benefit on what was then the residential condominium unit, initial year 2011, a fourteen-year term at a 50 percent abatement rate against roughly $1.17 million of certified alteration cost. The published file ends at tax year 2018, so the tail is not visible — but a fourteen-year term from 2011 exhausts in the mid-2020s. Ask the managing agent whether the J-51 has burned off and what it did to maintenance.

None of this building's house policies are published, which is normal for a small Tribeca loft co-op. Obtain the following from the managing agent, in writing, before offering: financing ceiling and minimum down payment; post-closing liquidity requirement; sublet policy — seasoning, term cap, fee, renewal practice; flip tax — existence, base, rate, and who pays; pied-à-terre policy, which in a building of full-floor lofts often decides whether a purchase is workable at all; and trust, LLC and co-purchase rules. The recorded transfer history shows at least one shareholder moving shares into a revocable trust, which suggests trusts are workable — but the board's written policy governs, not one precedent. The board package and interview are the real gate; confirm the expected timeline from accepted offer to closing with the managing agent.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. $/sf is measured on the latest sales with reliable square footage (2025): a median $1,723/sf (recorded) across 3 sales. The building has traded as recently as 2026. Median listing discount 0.0% from the last ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00225-0001). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

Ask about the J-51 first. A fourteen-year benefit that began in 2011 lands its burn-off in the present. Get the current tax bill, the current budget, and a straight answer on whether maintenance has absorbed the step-up.

Understand what the 2020 commercial acquisition did to the balance sheet. The corporation spent $4 million to buy in its own retail and refinanced the following year. Ownership brings rental income, commercial expenses, vacancy exposure and financing obligations; evaluate their net effect in the current accounts rather than presuming a benefit to shareholders.

The address in the documents may not match the door. Confirm that the contract, share allocation and proprietary lease identify the correct apartment and which of the Greenwich, Desbrosses or Watts entrances serves it.

Landmark review is real. Anything touching windows, storefront or a roof-level addition goes through LPC. Price the time, not just the work — run the Renovation Cost Calculator with a landmark contingency.

Do not rely on PLUTO here. Its year built is off by a quarter-century and its unit count disagrees with the certificate of occupancy.

Lead with the floor plate and the block. Horizontal warehouse space with original industrial sash on a cobblestoned Tribeca North street is the product; buyers arriving from condominium inventory need the format explained, not the finishes.

Put the corporation's ownership of the retail in front of the buyer's attorney early. Provide the acquisition records, commercial leases, net income and current debt terms so counsel and the lender can assess the financial effect; ownership alone does not establish credit quality.

Handle the abatement question proactively. If the J-51 has burned off, say so with the numbers. Ambiguity here loses deals late.

Price by section, not by building average. The six original warehouse sections produce genuinely different lofts.
