Overview of 21 East 90th Street

Nestled in the heart of Carnegie Hill, 21 East 90th Street stands as an appealing 14-story beige-brick building offering 50 cooperative apartments. It's impeccably managed and located on a serene tree-lined street that leads directly to Central Park through the elegant Engineer’s Gate.

This prime location enjoys the convenience of excellent cross-town bus service on 86th Street and a subway station at 86th Street and Lexington Avenue, with Central Park just a stone's throw away. Residents benefit from full-time doormen, a dedicated live-in superintendent, private basement storage, an on-site laundry room, and a bike storage facility. The building is welcoming to both pets and pieds-à-terre.

Architecturally, it features a charming two-step-up, canopied entrance, a vigilant doorman, uniform fenestration, appealing ground-floor retail spaces, sidewalk landscaping, and well-placed air-conditioning units. The building lacks a garage, balconies, and a health club.

The location is in close proximity to several prestigious private schools. Museum Mile and various cultural institutions are within easy reach, and the building shares its block with The Cooper Hewitt and its expansive garden. Carnegie Hill is celebrated for its dining establishments, shops, and overall inviting atmosphere. The towering luxury apartment tower at 45 East 89th Street is also a noteworthy neighbor.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
