87 Leonard Street

The surviving fabric is the argument for the building. Cast-iron Corinthian columns were retained and restored, ceiling heights in the principal residences run to roughly 17 feet, and the window openings are oversized double-sash to compare with measured openings in specific postwar alternatives. The conversion added a floor and raised the height from 72 to 85 feet, increasing zoning floor area from 24,830 to 29,817 square feet — an addition that in a designated historic district required LPC review, and that produced the two penthouse residences.

The residential plan runs to seven units: two at ground level (1A and 1B), full-floor plates at levels 2, 3 and 4, and two penthouses. Press accounts describe the full-floor residences at roughly 4,652 square feet with four bedrooms, with Calacatta marble bathrooms and a professional-grade kitchen specification. Those figures come from listing-side descriptions rather than from a plan on file and should be verified against the actual unit floor plan and the declaration's stated common interest.

One filing requires attention. A further alteration application was filed in April 2018 and fully permitted in January 2019 proposing to reduce the building from seven dwelling units to six. The DOB record shows the change in count but not how it is achieved: combining two residences and changing one residence to non-residential use would both produce it. DOB then issued temporary certificates of occupancy under that application showing six dwelling units (April 2020 through at least February 2021); no final sign-off appears in the open-data record. A buyer should establish the current legal use, the residential count and the common-interest schedule directly; a change in the physical count does not itself amend the declaration's common interests, so check whether an amendment was recorded.

The capital record is a landmark-district record. Façade waterproofing and repointing with a light-duty sidewalk shed appear in 2013; a heavy-duty shed and pipe scaffolding in 2014, 2016 and 2017; sidewalk vault repair applications in 2012 and 2016. In 2018 an alteration was filed and signed off to renovate the sub-cellar and cellar accessory recreation space specifically to resolve an ECB violation — a resolved compliance matter, but one worth confirming is in fact closed on the current record.

The live obligation to understand is the interaction of two cycles. The building sits in the Tribeca East Historic District, so exterior alterations generally require LPC approval and may also need DOB permits; some maintenance is exempt and qualifying work can receive staff approval. Scope and approvals determine cost and timing. FISP ordinarily applies above six stories; reconcile the reported six-story building and rooftop addition with DOB’s actual classification before assuming a filing cycle. In a seven-owner condominium, one remediation cycle under LPC review is a concentrated cost. Ask for current façade-condition reports and any applicable FISP filing, the reserve balance, and whether any assessment is contemplated.

What the common charges cover, the reserve position, and any current or recent assessment are not documented in any source available for this profile. That is a gap, and it is the first thing to close.

There is no 421-a and no J-51 at 87 Leonard Street. The Department of Finance assessment roll shows an exempt total of zero across the residential unit lots at the building in the most recent roll year published in the city's open data — the first year of residential occupancy. Neighbouring lots on the same block do carry exemptions, which confirms the reading is not an artefact of the dataset.

The practical effect is the same as at any unabated conversion: there is no step schedule to model and no expiry year, though future bills still change with assessments and tax rates — and also no subsidised entry. The tax line is a full share of the monthly carry from day one. Pull the current tax bill for the specific unit and run it through the True Monthly Carrying Cost Calculator rather than working from any projection.

Recent sales

Recent closings 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. Most recent trades (2025) cleared a median $1,066/sf (recorded) across 2 sales. Median listing discount -0.9% over ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00174-7504; each condominium apartment is its own tax lot). 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 from recorded condo declarations and offering plans.

Establish the current unit count. A 2019-permitted application proposed reducing the building from seven residences to six. DOB has since issued temporary certificates of occupancy showing six dwelling units; whether the change combined two residences or converted one to another use is not in the record. Confirm the current count with the managing agent and whether the declaration was amended to match.

Get the policy stack in writing. No offering plan for this building is held in either library. Pet, pied-à-terre, sublet, financing, flip tax and right-of-first-refusal terms are unverified. Do not assume Tribeca condominium defaults.

Price in the landmark constraint. Exterior work here requires LPC approval. That is a real cost and timing factor on any façade cycle, and it falls on seven owners.

Confirm the ECB matter is closed. A cellar and sub-cellar alteration was filed in 2018 to resolve a violation. Verify the current violation record on the BIN.

Confirm the lawful-use and tenancy history. Negative filing flags do not replace a full Loft Board and DOB search or the operative occupancy and tenancy records; assess any IMD, JLWQA or protected-tenancy issue before concluding it does not apply.

Verify the plate against the declaration. Published square footages are listing-derived. Check them against the recorded floor plan and the stated percentage of common interest.

Lead with the fabric. Restored cast-iron columns and roughly 17-foot ceilings inside a designated historic district are not reproducible, and that is the whole argument.

Arrive with the building file. The reviewed library did not contain the offering plan; supply it and the declaration, by-laws, current house rules, budget and financials so counsel can assess the building. Document availability alone does not establish the largest transaction obstacle or eliminate delay.

Be direct about the tax position. Unabated and stable is a defensible story; discovered late, it reads as a surprise.

Closing follows the condominium process. Right of first refusal rather than board approval; confirm the waiver timing in the declaration and bylaws.
