Twenty-eight feet wide, eleven stories tall, ten apartments. 15 West 17th Street is about as small as a Manhattan condominium gets while still being a real building, and the arithmetic of that is the whole proposition: every residential floor is a single apartment, the elevator opens into it, and there is no corridor, no lobby lounge, and no amenity program to fund. What a buyer gets is a private floor of roughly 2,200 square feet in a Beaux-Arts loft building on the Ladies' Mile blocks, with the running costs of a ten-unit house.
The building was put up in 1906–07 as store-and-lofts by William G. Pigueron, who according to LPC's own records for the Ladies' Mile Historic District was both its architect and, with G. H. Pigueron as owner, part of the family that developed it — a common arrangement on these blocks in the years when the department-store district was pushing north. The facade is brick over limestone with copper and cast iron, the copper being the detail that shows up a century later in the building's repair record.
It stayed commercial for most of its life. An investment entity bought the whole building in April 2005, and the condominium declaration was recorded on June 27, 2007. The ten residential floors and the ground-floor retail unit closed individually to eleven separate, unrelated buyers between November 2007 and December 2009 — the retail unit to a third party in December 2007, the rest to households — and the residential units have since traded repeatedly in arm's-length resales. This is a genuine for-sale condominium, not a rental in a condominium wrapper: all ten residential lots are assessed by DOF as R4 owner-occupied condominium units, none as class RR.
Architecture and unit composition
A 28-foot frontage on a 2,576-square-foot lot, built to 9.48 FAR across eleven floors. Twenty-two thousand square feet of that is residential, divided ten ways — floors two through ten as full-floor lofts plus a penthouse above. The floorplate is narrow and deep, which on a mid-block Ladies' Mile lot means light at the front and back and party walls on both sides; the compensation is the loft window wall and the ceiling height that comes with 1907 commercial construction. The keyed elevator arrangement documented in listing records means each apartment has the floor to itself with no shared landing. The ground-floor commercial unit occupies roughly 2,414 square feet and is separately owned.
Building operations
For a ten-unit condominium the operating model is necessarily lean, and the capital record shows the building addressing its facade on schedule rather than deferring it. DOB filings record a 2013 remedial program — window lintel removal and replacement with pointing, filed with a heavy-duty sidewalk shed and pipe scaffold — and a 2018 repair to the front facade at floors seven through ten that specifically addresses damaged copper panels, copper being one of the original facade materials in LPC's description of the building. That is two documented facade cycles inside a decade on a landmarked Beaux-Arts front, which is the right posture and also the right expectation for a buyer's reserve analysis: in a building this small, a facade cycle is spread across ten owners.
Loft history, occupancy and the Loft Law
The alteration that created residential use. DOB's open job file for this building is plainly incomplete — it carries a boiler replacement, a sprinkler job, two storefront renovations, the 2007 subdivision filing that created the condominium lots, and a scatter of apartment alterations, but not the alteration application that legalized residential occupancy. What the record does show is the transition itself: a January 2005 filing records the building's occupancy as commercial; filings from 2008 onward record it as residential, with ten dwelling units. PLUTO's yearalter1 of 1987 predates the residential conversion entirely and should not be read as the conversion date.
Loft Law and Interim Multiple Dwelling status. This is the finding that matters most here, and it is worth stating precisely. DOB's Loft Board indicator — the flag that marks a job as filed on a building within Loft Board jurisdiction — reads Y on three filings at this address: the January 2005 boiler application, the September 2007 subdivision application that created the condominium, and a March 2008 apartment alteration. From late 2008 forward every filing reads N, with residential occupancy. That pattern is consistent with the building having been an Interim Multiple Dwelling under Article 7-C of the Multiple Dwelling Law before and during the conversion, and having exited that status on legalization — which is exactly the arc the Loft Law was written to produce for pre-1930 Flatiron and Chelsea loft stock. We state it as what the filings show rather than as a legal conclusion: the Loft Board's own docket is not published as an open dataset, and a buyer whose diligence turns on residual Article 7-C questions, rent-regulated protected occupancies, or fixture-sale history should have counsel confirm the file directly.
Joint living-work quarters for artists. No JLWQA occupancy appears anywhere in DOB's record for this building, and the mechanism does not apply: JLWQA is authorized in the M1-5A and M1-5B loft districts, while this lot is zoned C6-4A with a residential FAR of 10.0, so residential use is permitted as of right. No Board of Standards and Appeals variance and no site-specific rezoning appear in the records we reviewed, and under this zoning none would have been required.
J-51. None. Unlike most loft conversions of the preceding generation, this one carried no J-51 exemption or abatement — DOF's roll is empty for both the base lot and the condominium lot. There is consequently no burn-off schedule to model and no step-up in real estate taxes ahead of a purchaser.
Policy framework
As a condominium, this building has no board approval and no financing ceiling in the cooperative sense — the governing constraints are the bylaws, the house rules, and the board's right of first refusal on a sale. Sublet and pet rules, the waiver procedure, move-in and move-out deposits, and any transfer fee are set by the bylaws and by resolution, none of which is published. Request the current rules, the last two years of financial statements, the reserve balance, and confirmation that the right of first refusal has been waived in prior sales, from the managing agent. In a ten-unit building, common-charge arrears in even one unit are a material share of the budget — read the receivables line in the statements.

Recent sales
15 West 17th Street trades on dollars per square foot, as all loft product does, and its pricing sits in the Flatiron loft-conversion band rather than the new-development band — pre-war bones, full-floor privacy, and no amenity package to justify a service premium. The absence of a tax abatement means carrying costs are transparent and stable rather than scheduled to step up, which matters to buyers comparing against abated new construction nearby. Renovation condition, not floor level, drives most of the spread between apartments; the penthouse carries the building's outdoor and light premium. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Underwrite the reserve, not the amenities. Ten units, a landmarked masonry-and-copper facade, and a documented repair cadence means a real reserve requirement. Ask for the reserve balance, any live assessment, and the most recent facade inspection report before contract.
Confirm the loft-law file. The DOB record indicates this building sat within Loft Board jurisdiction until legalization. That question is almost certainly closed, but it is a title and occupancy question worth asking counsel to close in writing rather than assuming.
Landmark obligations run with the facade. Windows, storefront and any exterior work go through LPC. Budget accordingly and expect a longer timeline than a comparable non-designated building.
A private floor is not a large floor. Twenty-two hundred square feet across the full width of a 28-foot lot lives differently from the same footage in a 50-foot building — long and narrow, with the light at the ends. See it before you decide it works; run the Renovation Cost Calculator against anything still in its 2008 finish, and the True Monthly Carrying Cost Calculator on the full unabated tax line.
What to know if you’re selling
The floor is the product. Keyed elevator, no corridor, no shared landing, whole-floor privacy. That is what distinguishes this building from the larger Ladies' Mile conversions, and it should lead.
Condominium tenure is a real premium in this pocket. Several of the nearest comparable loft buildings are cooperatives with boards and flip taxes. Buyers who want speed, foreign purchasers, and entity buyers will pay for the difference — market to that pool.
Have the building's documents ready. In a ten-unit condominium, buyers' counsel reads the financials line by line. Assemble the statements, the reserve position and the facade record before you list.

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.
