Overview of 233 East 70th Street

233 East 70th Street is a 17-story red-brick cooperative building located in Manhattan's Lenox Hill neighborhood. Built in the 1950s and converted to co-op in the late 1980s, the building features 89 units and maintains a boutique atmosphere with its brass entrance marquee and landscaped sidewalks.

The full-service building offers 24-hour doorman service, a newly renovated gym, central laundry facilities, bike storage, and private storage options for residents. The building is characterized by its corner windows and through-wall air conditioning units, though it does not feature balconies or a roof deck.

Residents benefit from a liberal ownership policy that welcomes pied-a-terres, co-purchasing arrangements, and parents buying for children. The building's pet-friendly policy and flexible subletting rules (allowing leasing after one year of ownership with a minimum two-year lease term) add to its appeal.

The location offers excellent transportation access, with the Q train at 72nd Street, the 6 train at 68th Street/Lexington Avenue, and cross-town bus service nearby. The building sits in a vibrant neighborhood near major medical centers, cultural institutions, and diverse dining options.

The cooperative maintains a professional atmosphere with recent improvements including lobby renovation and updated amenities. The building's relatively small number of units contributes to its intimate, residential character while providing full-service amenities expected in premium Upper East Side buildings.

Broker & Buyer Comments

This "well-maintained" full-service co-op offers a "no-frills but pleasant" atmosphere with its neutral lobby and coveted roof deck. "Pet-friendly" policies and possible storage options add to the appeal. The "prime Upper East Side location" - just blocks from Equinox and the future Second Avenue subway - makes this "solid investment" particularly attractive for those seeking convenience without flash.

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.
