A Private Pricing Opinion — what your apartment at 115 East 90th 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.
115 East 90th Street provides full-time door service in a nine-story prewar cooperative with 44 residences. The building sits just east of Park Avenue, with a mix of one-bedroom apartments, traditional five-room homes and larger combinations. Its scale allows a buyer to consider staffed Carnegie Hill ownership across several apartment sizes.
The building dates to the early 1920s and converted to cooperative ownership in 1978. Its interiors retain the room divisions associated with that period: entry foyers, separate dining rooms in the larger plans, windowed kitchens and bedrooms reached through their own circulation areas. Later combinations have created three-bedroom homes with multiple full bathrooms and substantially expanded living spaces.
East 90th Street leads directly west to Central Park and the reservoir. Lexington Avenue's express subway station at 86th Street is several blocks south, and the local station at 96th Street is to the north. The building's entrance occupies a side-street position within that broader avenue-and-park setting.
Architecture and unit composition
The standard apartment mix includes one-bedrooms with separate kitchens and dressing areas, and two-bedroom homes with formal dining rooms. The larger traditional plans can have one full bathroom plus a powder room. Other layouts provide two full bathrooms, while combinations bring additional bathrooms and living spaces into a single residence.
South-facing rooms overlook East 90th Street. Some apartments have multiple exposures, including north-facing bedrooms toward the rear gardens. Higher-floor homes can have a more open outlook, while the placement of the bedroom wing creates a different relationship to the street from the principal living room.
Windowed kitchens and bathrooms recur through the building. Renovations have opened some living-and-dining areas and updated kitchens while preserving foyers, bedroom separation and substantial closets. Through-wall or window air-conditioning arrangements depend on the apartment.
The combination inventory is especially important to the building's range. Larger homes can incorporate two living areas, a formal dining room and three bedrooms with three bathrooms. They occupy a different size category from the regular one- and two-bedroom apartments, even when they are on a middle floor.
Building operations
Full-time door service is supported by a live-in superintendent and handyman. The building also has central laundry, bicycle storage and private resident storage. The service model is substantial for a cooperative of this size and is part of its recurring maintenance structure.
Storage bins accompany some apartments, including larger homes with more than one storage allocation. The exact storage interest should be identified with the apartment being sold. A larger combination can carry more than one original storage entitlement.
In-unit laundry exists in some homes and can be installed with board approval. That permission is distinct from the common laundry room available to shareholders. The board's current alteration requirements govern proposed installation work.
The tax lot has no identified development abatement and is Class 2. The building's existing floor area exceeds the present R8B residential allowance, a feature of the established prewar structure.

Facade safety — Local Law 11
The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the inspector (QEWI) identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

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.
