Start with the confusion, because it is the first thing a buyer runs into. Type "10 Jay Street" into anything and you will get the DUMBO building — the converted Arbuckle Brothers sugar refinery on the Brooklyn waterfront, with its serrated glass entrance. That building is in Brooklyn, on BBL 3-00001-0050. The building on this page is in Tribeca, on BBL 1-00143-7501, and the two have nothing in common but a street name. Jay Street exists in both boroughs. Verify the borough and the BBL on any document before you rely on it.
The Tribeca building is a corner loft from 1896, built by Alexander Brown, Jr. — a mason and builder who developed it for himself and laid the masonry — to designs by John DeHart. It went up as a store and office building, six stories of masonry carried on cast-iron supports, at the moment the block was completing its late nineteenth-century commercial rebuild alongside the Schepp Building and the American Express Company Building on Hudson Street. In the early twentieth century it housed a fruit market with offices and storage above. By mid-century it held a nut-roasting factory, which is how the whole Jay–Harrison stretch of Greenwich Street was then used.
What makes the building unusual on the ground is Staple Street. The building's long elevation runs eighty-nine feet along a two-block private-feeling alley that is one of the most photographed pieces of streetscape in Manhattan — the cast-iron footbridge a block north belongs to the former New York Hospital House of Relief. Fourteen apartments sit above the ground-floor commercial space, on a corner lot with light on two sides and no through-block neighbor to the west. That combination — pre-1900 loft fabric, a landmarked alley elevation, corner exposure, and a fourteen-unit population — is the whole product.
The structural fact buyers most often miss is that this is not a condominium in the ordinary sense. It is a cond-op, and the difference is consequential at closing.
Architecture and unit composition
The Jay Street facade is organized in three bays per story, each carrying two large square-headed window openings separated by metal mullions and spandrel panels — the opening pattern of a commercial loft, and the reason the apartments have the glass they do. Stone-trimmed pilasters run up the elevation and terminate at the fifth story in stylized Corinthian capitals, with sheet-metal cornices marking the second and fifth floors. The sixth-story cornice is gone. At the base, the building keeps its loading platform, its masonry and cast-iron bay framing and its historic multipane transoms.
The Staple Street side has a one-bay return of the Jay Street composition, then a plain brick wall of five window bays per floor. That elevation is why the building reads as a Tribeca warehouse rather than a townhouse-scale conversion.
Inside, fourteen apartments across roughly 19,900 residential square feet averages out to loft-scale floor plates, and the plans are not uniform. The 2011 alteration on file (DOB job 120571657) split an existing duplex into two separate apartments, added a second-floor kitchen, and removed the spiral stair that had connected the duplex levels — taking the building from thirteen apartments to fourteen and producing the amended certificate of occupancy dated September 16, 2016. Earlier filings on file record apartment combinations in 2000 and 2003. Buyers should assume that line-to-line comparison inside this building is close to meaningless and that each apartment has to be underwritten on its own plan.
Building operations
The building runs lean: an elevator, a common roof deck, bicycle storage and private storage, and no doorman. For a fourteen-apartment building, that is the correct posture — a staffed lobby would fall on fourteen maintenance bills.
The cooperative corporation carries an underlying mortgage. ACRIS records financing agreements by Jeffersonian Jay Street Corp. in the amount of $1.1 million in 2015 and $1.5 million in 2021, both with the same institutional lender. That is a modest underlying balance for a building of this size, but the maturity date is the number that matters and it is not public. Ask for it, together with the current reserve position and the status of the most recent Local Law 11 façade cycle — DOB filings show façade repair work in 2007–2008 and again in 2019, which is the normal rhythm for a masonry building of this age in a historic district.
Note also that the ground-floor commercial unit is not owned by the cooperative. It is a separate condominium unit in third-party hands, which means the building's retail income does not flow to the residential owners, and the commercial owner has its own vote in the condominium board of managers. Anyone underwriting the building's finances should understand that the co-op's budget is a residential-only budget with a common-charge obligation to the condominium above it.
How ownership actually works
In August 1986 the then-owner, Fifth Jeffersonian Associates, recorded a condominium declaration dividing the building into exactly two units: the ground-floor commercial space and everything above it. The commercial unit — lot 1001 — was sold off separately in April 1987 to a flag manufacturer and is today held by a limited liability company. The residential unit — lot 1002 — was conveyed to Jeffersonian Jay Street Corp., a cooperative corporation, which then issued shares to the residents of the fourteen apartments.
The result is that the Department of Finance classifies lot 1002 as building class R9 — a co-op within a condominium — and it means that when you buy an apartment here you are buying cooperative shares and a proprietary lease, not a deeded condominium unit. Transactions record in ACRIS as real property transfer tax filings against the co-op's single tax lot rather than as deeds against an apartment lot. Board approval applies. Financing is share-loan financing, not a mortgage on a deeded unit. Some market records describe the building as a condominium because PLUTO's building class for the parent lot is RM; that is a description of the mixed-use condominium wrapper, not of what a purchaser acquires.
The practical advantage of the structure is that a cond-op board's transfer rules are set by the cooperative's own governing documents rather than by the Business Corporation Law defaults alone, and many cond-ops adopt materially looser sublet, pied-à-terre and entity-purchase rules than a comparable straight co-op. Whether that is true here is a question for the managing agent, because this building publishes nothing.
Policy framework
The policy stack for this building is not published anywhere reliable, and this page will not guess at it. The management-sourced portal that handles board packages here lists only transfer fees — a non-refundable application processing fee, a screening report fee, and an optional expedited fee — and no pet, sublet, pied-à-terre, financing or flip-tax terms.
Get the following in writing from the managing agent before you commit to a price: the maximum financing percentage, any post-closing liquidity requirement, the flip tax or transfer fee, the sublet policy and any waiting period, the board's posture on pied-à-terre use and on purchases by trusts and LLCs, and the pet rules. In a cond-op these terms are frequently more permissive than in a conventional co-op, which is exactly why they should be confirmed rather than assumed in either direction.

Recent sales
Fourteen apartments produce a thin transaction record — a handful of trades in a decade — so this building prices off Tribeca loft comparables rather than off its own history. Recorded share transfers over the past decade have clustered in the low seven figures, with the largest apartments trading at multiples of that, and the spread between the smallest and largest transactions in the building is very wide. A single "average price" for 10 Jay Street is not a usable number.
What the market pays for here is prewar loft fabric on a landmarked corner in the Duane Park end of Tribeca, with the Staple Street elevation and the roof deck as the differentiators, and it discounts for the absence of a doorman and of any amenity program. Buyers should also price the cond-op structure honestly: share ownership with board approval narrows the buyer pool relative to a deeded Tribeca condominium, and that shows up at resale. Index any market statement here to 2025, the last complete year. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Market read. Most recent trades (2025) cleared a median $1,844/sf across 1 sale. Median listing discount 6.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
Confirm the borough on every document. The DUMBO building of the same address will appear in searches, valuation tools and title work. The Manhattan BBL is 1-00143-7501; the Brooklyn one is 3-00001-0050.
You are buying shares, not a deed. Budget for a co-op board package, a co-op share loan and a co-op timetable, even though the building sits inside a condominium.
Ask for the underlying mortgage maturity. The balance is modest; the maturity date is the risk.
Landmarks governs the exterior. Windows and any street-visible alteration on either the Jay Street or Staple Street elevation require a Certificate of Appropriateness. Budget the process, not just the work.
Underwrite full taxes. There is no J-51 and no 421-a here. The only abatement is the standard co-op/condo abatement for primary residents, and it is already in the number.
What to know if you’re selling
Lead with the corner and the alley. The Staple Street elevation, the two-sided light and the 1896 fabric are the product; there is no amenity story to tell and no reason to try.
Explain the cond-op before a buyer's attorney does. Buyers who arrive expecting a condominium and discover a board package late in the process walk. Framed early, the structure reads as a Tribeca co-op with looser rules — which is a better story.
Document the plan. With apartment combinations and a duplex split in the building's history, an accurate floor plan with the DOB approvals behind it is worth real money.
