685 West End Avenue is one of the larger apartment houses built on upper West End Avenue in the great 1928 building season, and it has never lost the qualities that made it desirable then. Designed by Sugarman & Berger — a firm responsible for a wide range of New York apartment and commercial buildings in the 1920s — it rose fifteen stories at a moment when West End Avenue, with its proximity to Riverside Park and the new transit along the West Side, was drawing the city's most sought-after tenants. When it opened that October, more than half of its ninety original apartments had already been spoken for; the building has held that pre-war prestige across nearly a century.
What distinguishes it today is the combination of generous pre-war layouts, a quiet residential block near 93rd Street, and a full-service operation that punches above the building's size. The lobby has been restored and renovated, and the roof deck — furnished and landscaped, with open views that reach to the Hudson — is the kind of shared amenity that turns a co-op into a community. For buyers who want classic West End Avenue scale without the price of the avenue's marquee names, 685 is a serious, livable address.
Architecture and unit composition
The building reads as a confident piece of late-1920s West End Avenue masonry: a fifteen-story brick-and-stone façade, a deep lobby, and the proportioned windows and high ceilings of the pre-war era. Apartments were originally laid out from three to six rooms and have evolved into a mix of one-, two-, and larger family-sized homes, many retaining the entry foyers, separate dining rooms, and detailed ceilings that define the period. Upper-floor lines on the western flank capture light and partial Hudson outlook to the west.
At 96 apartments across fifteen floors, the building is intimate enough to feel managed and personal, yet large enough to support a real staff and a full amenity package — a balance pre-war buyers consistently prize.
Building operations
685 West End Avenue runs as a full-service cooperative with a full-time doorman and a live-in superintendent. The renovated lobby, central laundry, and landscaped rooftop deck round out the resident experience. Pets are permitted under the building's house rules. In-unit washers and dryers are allowed. Subletting is permitted with board approval; the cooperative charges a sublet surcharge equal to 30% of monthly maintenance for the duration of a sublease, with a partial rebate when the shareholder returns. Pied-à-terre purchases are not permitted — this is an owner-occupied building, and parents-buying and corporate purchases are not allowed.

Facade safety — Local Law 11
Safe to live in today — but the last inspection flagged repairs that are due on a deadline, so facade work and its cost are coming. Whether that’s a real concern depends on the scope, the timing, and how the building plans to pay for it — reserves or an assessment — which is exactly what we’d dig into for you.

The /sales tab below draws live from the building's tax lot. As a 96-unit cooperative, 685 West End sees a measured, pre-war cadence of turnover — typically a handful of closings in an active year rather than the steady churn of a large post-war tower. Pricing tracks the upper West End Avenue pre-war market, where value is set by line, floor, light, and the quality of the renovation; classic six- and seven-room homes command a clear premium over the smaller lines, and high-floor river-view apartments sit at the top of the building.
What to know if you’re buying
This is a board-approval cooperative, and a complete, well-documented purchase application is essential. Financing is capped at 75% of the purchase price, so buyers should plan for at least 25% down plus the post-closing reserves the board expects to see. A 1% flip tax, paid by the seller, applies on resale — useful to factor into your offer strategy because it shapes how sellers price their net. Pets and in-unit laundry are both allowed, which widens the buyer pool; the building is owner-occupied, so a pied-à-terre or investment purchase is not the right fit here. We help buyers assess the line and exposure, read the financials, and prepare a board package that clears cleanly.
What to know if you’re selling
The selling case is the full-service, pre-war, park-adjacent package: a doorman building with a restored lobby and a landscaped roof deck, on a quiet upper-West-End block two blocks from Riverside Park. Buyers pay for that combination. Price to the building's own comparable set — recent closings in similar lines and floors here and at the neighboring pre-war co-ops — and lead with what's scarce: light, ceiling height, original detail, and the quality of any renovation. The 1% seller flip tax should be built into your net-proceeds expectations from the start; our Seller Closing Cost Calculator below makes that straightforward.
