15 West 17th Street

A 28-foot frontage on a 2,576-square-foot lot, built to 9.48 FAR across eleven floors. Twenty-two thousand square feet is recorded residential gross area, not the sum of measured apartment interiors — 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.

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 facade filings inside a decade on a landmarked Beaux-Arts front; completion and current condition need confirming, and project costs should be allocated under the declaration among the ten residences and the separate commercial unit, with reserves and financing considered.

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 on the roll. DOF's roll shows no J-51 exemption for either the base lot or the condominium lot; check the apartment's tax bill for any abatement. There is no J-51 burn-off schedule to model, though taxes still change with assessments and rates.

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, the current versions of which were not available in the materials reviewed. 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

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 (2026 to date) cleared a median $1,222/sf (recorded) across 2 sales. Median listing discount 2.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00819-7504; 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.

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. The change in filing flags does not establish that all Loft Board matters are closed; have counsel confirm the docket, occupancy record and any remaining obligations directly.

Landmark obligations run with the facade. Window, storefront and other exterior alterations generally require LPC approval, while specified routine maintenance is exempt. Confirm the scope and permit route before budgeting the schedule.

A private floor is not a large floor. The 28-foot lot suggests a narrow floor plate; the roughly 2,200-square-foot gross-area quotient does not establish the apartment’s actual interior size, shape or light. Review its measured plan and exposures. 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.

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.

Explain the condominium ownership framework. Several of the nearest comparable loft buildings are cooperatives with boards and flip taxes. Compare the actual application and ownership rules without promising a faster closing or a tenure premium for any buyer group.

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.
