Two nineteenth-century store-and-loft buildings sit on one tax lot here, and the cooperative owns both. No. 56 went up in 1880–1881 to a design by M. G. Lane for the Brevoort family, who were building speculatively on Warren Street as the dry-goods trade pushed north from the old commercial core. No. 58 followed in 1887–1888, designed by John B. Snook & Sons — the firm behind the first Grand Central Depot — and at some point the Snook office also altered No. 56. Both are Renaissance Revival in brick with sandstone trim and pressed-metal cornices, and both were built to hold merchandise on five floors above a store. The Landmarks Preservation Commission recorded all of this when it designated the Tribeca South Historic District Extension in November 2002.
That designation is worth reading carefully, because it is the answer to a question buyers ask constantly on this stretch of Warren Street. The Tribeca South Historic District and its 2002 Extension do not cover the whole street. They run roughly between Church Street and West Broadway, which puts 56 Warren inside and puts buildings a block west outside. The pages we maintain for 8 Warren Street (block 135), 12 Warren Street (block 135) and 41 Warren Street (block 133) are all different tax blocks from this one, which sits on block 136. Address proximity on Warren Street tells you very little about landmark status, tax class, or building form; the tax lot tells you everything.
The commercial history matters to the economics. The cooperative owns two ground-floor retail units outright, and the income from them offsets what shareholders pay in maintenance. In an eight-apartment building that ratio is unusually favorable — the retail rent is spread over a very small denominator, and maintenance per apartment has historically run low for a Tribeca loft of this size. It also means the building's finances are more exposed to a single retail vacancy than a larger co-op's would be, which is the trade a buyer is actually making.
The conversion itself dates to October 1981, when the building was deeded from its prior corporate owner to 56 Warren Owners Corp. That places it among the earlier Tribeca residential conversions, well before the neighborhood's condominium era, and it explains the building's form: eight full loft apartments, two per floor across floors two through five, in an envelope that was never subdivided into anything smaller.
Architecture and unit composition
The apartments are true lofts. Two per floor on floors two through five, lettered East and West — the pairing is confirmed by recorded share transfers and by decades of DOB alteration filings on individual units. Ceilings are high, windows are oversized on both the Warren Street elevation and the rear, and interiors typically retain exposed brick, timber structure and wide-plank flooring. Because the lot is nearly 46 feet wide and 100 feet deep, the plates are broad rather than narrow, which is what allows two genuinely separate apartments per floor rather than the long shotgun layouts common in narrower Tribeca loft buildings.
Renovation activity in the building has been steady and unit-by-unit rather than building-wide: individual apartment gut jobs appear in the DOB record across 2005, 2006, 2007, 2008, 2010, 2012, 2013, 2014 and 2020. Several carry per-apartment boilers and independent mechanical systems, which is worth understanding before underwriting a purchase — heating and cooling responsibility in a building like this is often unit-level, not central.
The rear elevation abuts development on West Broadway; a 2007 DOB filing at this address was made in conjunction with new construction at the adjoining 85 West Broadway site. Rear light and air on this lot should be checked window by window rather than assumed.
Building operations
This is a self-managed-scale building run through a managing agent, with a part-time superintendent and no doorman. Amenity is minimal by design: a passenger elevator, intercom entry, and oversized basement storage assigned per apartment. What the building spends money on instead is fabric. The DOB record shows rear-façade repair in 2012, sidewalk and vault reconstruction in 2015, an alteration filed in 2016 for structural steel framing to carry a landscaped roof deck (a filing that required a new certificate of occupancy), and a domestic water booster pump system filed in March 2026. Boiler work in individual apartments appears in 2020 and 2021.
An underlying mortgage of $500,000 was recorded against the cooperative in October 2002 with a cooperative-specialist lender, with assignments recorded in 2002 and 2003. That is a small underlying debt by Manhattan co-op standards, but it is more than two decades old and the current balance, rate and maturity should be read out of the audited financial statements rather than inferred from the recorded instrument.
Policy framework
Ownership form: Cooperative. Purchase is a share transfer accompanied by a proprietary lease, with a full board package and interview.
Everything else is unpublished. We could not verify a flip tax, a financing ceiling, a sublet policy, a pied-à-terre position, or a pet policy for this building from any source we are prepared to stand behind. In an eight-shareholder cooperative, those terms are frequently set by board resolution and house rule rather than by the offering plan, and they change. Request them in writing from the managing agent before you make an offer, not after.

Apartments here trade as full-floor-scale Tribeca loft product in a very small building — a category that prices on ceiling height, light, and condition rather than on services, because there are no services to price. Recorded share transfers run across all four residential floors and both lines over roughly two decades, so the building has a real, if thin, internal comparable set; with eight apartments, a single trade moves the building's apparent average materially, and line-by-line and condition-by-condition analysis is the only honest way to price a unit here. Compare against small Tribeca loft cooperatives rather than against full-service condominiums, whose common-charge and staffing economics are not applicable. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00136-0012) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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.
What to know if you’re buying
Get the policy stack in writing first. Flip tax, financing ceiling, post-closing liquidity expectation, sublet rules, pied-à-terre position, and whether trusts or LLCs are entertained — none of it is published. In a building this small, the board's practice is the policy. Ask the managing agent for the current house rules, the sublet policy, and the most recent two years of audited financials before you write an offer, and run the Co-op Board Qualification Calculator against whatever ceiling comes back.
Eight shareholders is the risk and the appeal. Capital assessments in a building this size land hard per apartment, and there is no reserve of scale to absorb a façade cycle. Read the reserve position and the retail lease terms together — the retail income is what keeps maintenance low, and its renewal date is a number you should know.
The Loft Law question is open. DOB filings from 2003 through 2008 carry a Loft Board indicator and later filings do not. We could not confirm whether any apartment ever held Interim Multiple Dwelling status. If it matters to your unit, have counsel ask the Loft Board and the managing agent directly.
Landmark designation constrains the exterior. The building sits in the Tribeca South Historic District Extension. Windows, storefronts and any rooftop work require Landmarks review in addition to DOB approval. The 2016 roof-deck filing is a useful precedent to ask about — including whether the resulting certificate of occupancy was ever issued.
Verify the elevator, then verify the tax class. The Department of Finance carries this lot as building class C6, a walk-up cooperative code, while market records describe a passenger elevator. Automated valuation tools that key off building class will mis-handle this building.
What to know if you’re selling
Lead with the two things that are structurally scarce: a designated 1880s store-and-loft envelope with two apartments per floor, and cooperative-owned retail income in an eight-unit building. Both are verifiable and neither can be replicated by newer inventory nearby.
Correct the record before a buyer's attorney does. PLUTO's 1915 year-built and C6 building class are both misleading here. Present the LPC record — 1880–1881 and 1887–1888, M. G. Lane and John B. Snook & Sons — up front.
Assemble the diligence package early. With no published policy stack, the buildings that close cleanly in this size class are the ones where the seller has the financials, house rules, sublet policy and current retail lease summary ready on day one.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent.
