407 East 91st Street

The building's bones are its best argument. As a converted industrial structure, 407 East 91st Street offers loft-style homes with high ceilings and large open floor areas — layouts that lend themselves to lofts, home offices, and combined living-and-entertaining spaces in a way that boxy apartment plans rarely do. Some residences carry distinctive features that survived or were added in conversion, including upper-floor units with private outdoor space; the building's terraces and sunrooms are among its most sought-after attributes.

With 35 units across five floors, density is low and most owners enjoy a real sense of privacy. The masonry exterior is unfussy and authentic to its 1901 origins — a workmanlike façade that signals the building's history rather than dressing it up. Apartments range from studios and lofts to larger multi-room layouts, with the open plans giving buyers latitude to configure space to their own use.

407 East 91st Street is run as a self-contained, owner-occupied cooperative. The building has an elevator, a live-in resident superintendent who handles day-to-day maintenance and security, a central laundry room, and a package and storage room. There is no doorman — consistent with a boutique loft building of this scale — and a parking garage sits directly across the street, an unusual convenience this far east. There is also bicycle storage for residents.

On house policy, the building is pet-friendly, and washer/dryers are permitted within apartments — both meaningful for loft buyers and not a given in pre-war Yorkville stock. As with most cooperatives, purchases are subject to board review and approval, and financing and sublet terms follow the building's proprietary lease and house rules; we walk buyers through the current specifics as part of any transaction.

Market read. Most recent trades (2025) cleared a median $658/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 6.4% 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 1-01571-0008). 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 on co-ops is not officially recorded, figures shown are approximate.

The appeal here is space and character, and the diligence should follow the space. Confirm the exact ceiling height, window exposure, and outdoor-space rights of the specific unit, since loft conversions vary line to line. Because this is a cooperative, expect a board package and interview, and budget for the building's maintenance and any underlying-mortgage and reserve posture — a five-story building with 35 owners spreads costs across a small base, so reviewing the financials matters. The pet-friendly, washer/dryer-permitted rules are a genuine plus for the loft buyer. The location — between First and York in deep Yorkville — puts Carl Schurz Park, Asphalt Green, the Q train at 96th/Second Avenue, and the crosstown bus all within easy reach, with neighborhood restaurants and groceries close by.

Lead with what is rare: this is a true loft cooperative in a neighborhood that has almost none. The marketing should foreground ceiling height, open volume, light, and — where applicable — private outdoor space, because those are the attributes a buyer cannot replicate in standard Yorkville inventory. Stage to show the flexibility of an open plan rather than forcing it into conventional rooms. With so few units, comparable sales are thin, so positioning against both the building's own history of trades and the broader Yorkville loft and value market is essential to pricing correctly. The pet and washer/dryer policies are selling points worth stating plainly.
