A Private Pricing Opinion — what your apartment at 617 West End Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
617 West End Avenue is a corner pre-war cooperative on the Upper West Side, designed by Schwartz & Gross and built in 1924–25. Its defining feature is its layout: confirm the stated two-apartment landings and current floor allocations across 14 stories; actual privacy, daylight and proportions depend on the specific plan and surroundings. The building offers staffing around the clock.
West End Avenue is the Upper West Side's quintessential residential corridor — a wide, tree-lined avenue of grand pre-war co-ops, one block from Riverside Park and the Hudson, two from Broadway's retail and transit. 617 sits at the West 90th Street corner, a position that gives its apartments cross-light and quiet. Converted to a cooperative in 1979, it remains the kind of character-rich building that defines ownership on this stretch.
Architecture and unit composition
Schwartz & Gross designed 617 West End Avenue (LPC, 1924–25). The result is an attractive red-brick elevation rising over a two-story limestone base — a building that reads as a confident piece of 1920s Upper West Side design rather than a standard masonry box. Residents enter through a step-down paneled lobby that preserves the building's pre-war character.
The two-apartments-per-floor configuration yields generous, light-filled homes with multiple exposures. The 33 residences carry the era's hallmarks — high ceilings, hardwood floors, separate kitchens, and gracious entry foyers — across a mix averaging roughly 1,570 square feet of building area per unit. Corner apartments enjoy the dual frontage on West End and 90th.
Building operations
617 West End is run as a full-service cooperative. A full-time doorman/elevator operator staffs the entrance around the clock and a live-in resident manager handles building operations, with a central laundry room, a bike room, and storage assigned to each unit among the amenities. The 24-hour elevator-operator service is a traditional touch that distinguishes the building's level of attention.
The board permits pets, and washer/dryers are allowed with board approval — both meaningful policy points for buyers. As at most West End Avenue co-ops, purchases require board approval and a financing limit applies, and subletting is permitted under board policy after an initial owner-occupancy period. We review the precise sublet terms and any flip tax with buyers before they bid so underwriting reflects the building's actual rules.
Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the inspector (QEWI) identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

What to know if you’re buying
Plan for a co-op board application, including financial disclosure, references and an interview, and confirm current financing limits. Assess privacy, light and proportions in the apartment. Confirm current pet, washer/dryer and sublet rules with the managing agent, including any board approval required. Test price differences for corner and higher-floor apartments against dated transactions.
What to know if you’re selling
The selling story is architecture, layout, and location: a Schwartz & Gross pre-war co-op with two apartments per floor, a paneled lobby, and full-service staffing, one block from Riverside Park. Buyers on West End Avenue are underwriting pre-war character and the privacy of a low-density floor plate — present and price to that. Benchmark against comparable full-service West End Avenue pre-war co-ops, and lead with the named architect, the corner light, the period detail, and the proximity to the park and Broadway. Use matched transactions to assess how renovation and retained period features affect this apartment’s price.

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. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
