114 East 90th Street

The building is a representative example of mid-1920s Upper East Side apartment design — a red-brick elevation over a quiet limestone base, even fenestration, and the kind of solid masonry construction that gives pre-war apartments their thick walls and sound separation. There is no ornamental flourish here; the value is in the bones.

Inside, the 38 residences span the pre-war range, from intimate one- and two-bedrooms to larger family layouts. Expect the hallmarks of the era: high ceilings, hardwood floors, separate kitchens, and the generous closet and foyer space that newer construction rarely matches. At roughly 1,400 square feet per unit on average across the building, the mix skews toward usable, well-proportioned apartments rather than oversized full-floor spreads.

114 East 90th is run as a full-service cooperative. A 24-hour doorman staffs the lobby and a live-in resident manager handles day-to-day operations, with a central laundry room, a fitness room, a bike room, a children's playroom, and individual storage bins among the shared amenities. The landscaped courtyard is a genuine differentiator on a block of this scale — usable outdoor common space is scarce in pre-war Carnegie Hill.

The board permits pets, including dogs and cats — a meaningful point of difference from the stricter co-ops nearby. As with most Carnegie Hill cooperatives, purchases are subject to board approval and a financing limit, and subletting is permitted on a controlled basis after an initial residency period; specific thresholds are set by the board and reviewed as part of the purchase application.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01518-0061) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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.

This is a board-approval building, so plan for a full co-op purchase application — financial disclosure, references, and a board interview. Budget for the building's financing limit when structuring your offer; co-ops of this vintage typically cap the percentage of purchase price that may be financed. The pet-friendly policy is a real advantage for buyers with dogs, who find Carnegie Hill's stricter buildings a hard fit. Confirm the precise sublet terms and any flip tax with us before you bid so your underwriting reflects the building's actual rules rather than assumptions.

The locational case is strong and durable: a quiet residential block, a top school catchment, the park and Museum Mile within easy reach, and the 4/5/6 at 86th Street plus the Second Avenue line a short walk east. That combination supports value here regardless of the broader market.

The selling story is location and full-service stability. Carnegie Hill's school proximity, the leafy side-street setting, and a deep amenity package — courtyard, gym, playroom, doorman — are exactly what family buyers in this segment are underwriting. Pricing should be benchmarked against comparable pre-war Carnegie Hill co-ops of similar service level rather than against condominiums or Fifth Avenue trophies; the buyer here is choosing co-op value and neighborhood, and the comparable set should reflect that. A renovated, well-lit apartment with the building's amenities behind it competes well, and the pet-friendly policy widens the buyer pool meaningfully.
