Austin Nichols House (184 Kent Avenue)

The condominium contains 338 residential units, one of which was conveyed to the board as the superintendent's unit, plus two non-residential units — a Retail Unit of roughly 17,000 to 17,900 square feet and a Garage Unit recorded in the amendments at between 58,348 and 60,947 square feet across three levels. Neither was offered for sale. Before the residential conversion the building had been divided into 53 units under a 2009 No Action Letter; the 2016 plan re-divided it into the current configuration.

The unit inventory runs from studios through three-bedrooms, and the floor plate's own logic organizes it. Because the building is a warehouse — deep, low, and wrapped around a central courtyard — the apartments divide into three families: units on the western elevation, facing the East River and the Manhattan skyline directly; units on Kent Avenue and the side streets; and units facing the interior courtyard, which Gilbert cut precisely so the middle of the building would have light. Ceiling heights, column grids and window bays are those of a 1915 concrete industrial floor, and that is the product: the loft volume and the mullion rhythm are the reason to buy here rather than in a tower two blocks north.

The plan's Schedule A gives an unusually clear read on how the sponsor priced that inventory at conversion. A 532-square-foot studio on the second-floor A line was offered at $682,500 — $546,000 to the sitting tenant — with monthly common charges of $454. A 1,192-square-foot three-bedroom on the same line carried an offering price of $1,890,000, $1,512,000 to the tenant, with monthly common charges of $1,016. Those are 2016-era sponsor figures and not comparables, but they are the clearest available picture of the building's internal price architecture — a steep premium for size and for the river elevation, a modest one for floor — and that architecture has largely held.

Sixty-three storage bins were offered as licenses rather than as separately deeded units, at $40,000 for a 30-square-foot bin and $50,000 for a 54- to 56-square-foot bin. Because they are licenses appurtenant to a unit rather than conveyed real property, the mansion-tax treatment differs from buildings where storage is a separate tax lot — worth raising with counsel on a contract written near the threshold.

Austin Nichols House operates as a full-service condominium with an attended lobby, a resident superintendent housed in the board-owned unit, and an amenity program built into the conversion: the living green wall in the lobby, a fitness center on the river side of the building, a screening room, a music room, children's space, and shared roof terraces. The parking garage below the building is a separate condominium unit under separate ownership, as is the retail; public reporting indicates both were sold together to a third-party owner in 2021 for a reported $11.7 million. That structure matters operationally, because garage and retail are neighbors rather than house amenities, and their common-charge allocations — 0.7198 percent for the garage and 2.4701 percent for the retail, per the plan — are fixed in the declaration.

The tax structure is the operational fact that most distinguishes this building from its waterfront neighbors. The towers up the shoreline carry Section 421-a benefits, granted for new construction. Austin Nichols House is a rehabilitation, and it carries J-51 — which is why the plan's Schedule A is laid out with paired columns showing every unit's carrying cost with and without the benefit. At conversion the J-51 line for the units reviewed was zero, against un-abated annual taxes of roughly $3,148 for the 532-square-foot studio and roughly $7,053 for the 1,192-square-foot three-bedroom. On the studio the abatement was the difference between $454 and $716 a month in total carrying cost, and on the three-bedroom between $1,016 and $1,604. J-51 abatements run a fixed term and then stop; underwriting here off the current tax line without checking the remaining term is underwriting the wrong building.

Finally, occupancy. A portion of the apartments were occupied by rent-stabilized tenants at conversion and the sponsor was free to keep renting rather than selling. The practical questions for a purchaser are the current owner-occupancy ratio, which lenders care about; the sponsor's remaining unsold inventory; and whether the specific unit has a regulated tenancy history. All three are answerable from the condominium's records, and should be answered before contract.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02348-7501) and verified listing data.

Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

You are buying a Cass Gilbert building, and the paperwork proves it. The National Register listing from 2007 is the durable protection on the exterior; the New York City individual designation from 2005 was overturned by the Council in 2006 and does not apply. That distinction is not academic — it governs what can be altered and by whose review.

J-51 is the carrying-cost question, not 421-a. The plan lays out both scenarios unit by unit. Get the remaining benefit term from the Department of Finance record and run True Monthly Carrying Cost on the un-abated number.

Ask about occupancy and sponsor holdings before you contract. This was a non-eviction conversion with rent-stabilized tenancies. Owner-occupancy percentage, sponsor-owned unit count, and the specific unit's tenancy history are all documented and all matter — the first to your lender, the others to your resale.

Exposure is the price driver, not floor. Six stories means altitude does very little here. River-facing, street-facing and courtyard-facing are three different products.

The retail and garage are neighbors, not amenities. Both are separately owned condominium units with fixed common-interest allocations; understand what the building actually operates before you price the amenity package.

Loft geometry cuts both ways. Warehouse column grids, deep plates and 1915 window bays give volume and light patterns a new tower cannot reproduce — and irregular rooms with columns in inconvenient places. Walk the specific unit.

Lead with the building, then the apartment. Gilbert, 1915, Egyptian Revival, the Woolworth architect's only major warehouse, the landmark fight, the National Register listing. No other building on this waterfront has that story, and the buyers who pay the premium here are buying it.

Have the tax answer in hand. The J-51 remaining term and a modeled un-abated carrying cost, prepared before the first showing, is the single highest-return piece of seller preparation in this building.

Anticipate the occupancy questions. Current owner-occupancy ratio, sponsor inventory, and the unit's own tenancy history. A buyer's attorney will ask; a seller who answers first sets the tone of the negotiation.

Price against your elevation, and be clear about what a loft conversion is. River-facing comparables do not price Kent Avenue units and neither prices courtyard units — same-exposure, same-size closings are the only honest anchor. And buyers cross-shopping the towers should be steered toward volume, fenestration and provenance rather than into an amenity comparison this building will lose.
