A Private Pricing Opinion — what your apartment at 108 East 66th Street 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.
108 East 66th Street is a prewar Lenox Hill cooperative of 1926, a ten-story apartment house of just 18 residences on one of the Upper East Side's most storied blocks — mid-block between Park and Lexington Avenues, directly facing the Park Avenue Armory. Its ownership entity of record is 108 East Owners Corp., the classic cooperative corporation structure, and the building trades as a genuine prewar co-op with individual share sales.
The building's defining traits are its scale and its address. With a maximum of roughly two apartments per floor, it is a boutique, low-turnover cooperative; and its position across from the Armory places it within the Upper East Side Historic District, on a block that pairs residential prewar dignity with landmark civic architecture. Upper-floor residences enjoy open exposures and long city views.
Architecture and building operations
108 East 66th Street is a 1926 prewar apartment house of ten stories on a 25-foot-wide Lenox Hill lot, roughly 21,800 square feet in building area, with a modest ground-floor commercial component. The apartments carry classic prewar detailing — high ceilings, some beamed — and the building falls within the Upper East Side Historic District, so exterior work is subject to landmark review. Operations: Elevator-served with central air, a central laundry room, and a renovated lobby; a boutique building operated with the intimacy that its 18-unit share count implies.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01400-0068). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

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.
