About the building
517 East 87th Street is a small, five-story cooperative on a side street between York and East End avenues. Its early-1980s conversion offered eight apartments, with the plan becoming effective in April 1984. The building retains the scale of a narrow prewar walk-up, and common laundry and storage are part of its shared facilities. The tax lot is outside a designated historic district.
Upper-floor apartments include one-bedroom plans, some with high ceilings and open sleeping platforms. At the base, a much larger triplex incorporates the first two floors and a lower level, with a private rear garden. That arrangement creates a substantial difference in both interior circulation and outdoor access within a single cooperative. In-unit laundry exists in some apartments; access to the upper floors is by stairs.

What to know if you’re buying
An open sleeping platform in an upper-floor apartment adds usable space without establishing a separate enclosed bedroom. At this address, a one-bedroom home with a loft should be evaluated using its approved room arrangement and the platform's actual headroom and stair access.

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.
