A Private Pricing Opinion — what your apartment at 1091 Lexington Avenue 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.
1091 Lexington Avenue sits at the center of Lenox Hill, on Lexington at East 77th Street — one of the most consistently in-demand stretches of the Upper East Side. The 6 train at the 77th Street station is essentially at the door, the Madison Avenue retail and gallery corridor is a block west, and the cross-streets connect quickly to Central Park and Museum Mile. It is a quintessential "live everywhere on foot" Upper East Side address, with neighborhood retail at the building's own base and the restaurants and groceries of upper Lexington and Third Avenue all within a few hundred yards.
The building belongs to the late-1950s postwar cooperative generation that reshaped the avenues of the Upper East Side. As Lenox Hill's older low-rise stock gave way to taller full-service buildings, developers built apartment houses designed around efficient layouts, full staffing, and the practical needs of a residential community rather than the ornamental ambitions of the pre-war era. 1091 Lexington is a clean example: 16 stories, roughly 95 apartments, and a scale that supports a real staff while keeping turnover and anonymity low.
For a buyer who wants a central Lenox Hill address with a postwar floorplan — larger windows, efficient room flow, the conveniences of mid-century construction — at pricing typically more accessible than the pre-war and Park-block tiers nearby, 1091 Lexington occupies a useful niche in the corridor.
Architecture and unit composition
The exterior is characteristic of refined late-1950s Upper East Side construction: a brick body on a limestone-trimmed base, organized as a clean, vertical facade without heavy ornament. The era's design emphasis was on the apartment interior and on light, not on facade decoration; the avenue base carries ground-floor retail in keeping with Lexington's mixed-use character.
Across the 16 stories, the roughly 95 apartments span a range of configurations, from compact one-bedrooms to larger two- and three-bedroom homes; some lines run to substantial three-bedroom, three-bath layouts in the 2,000-plus-square-foot range. Postwar signatures recur throughout: efficient room flow, generous closet runs, and large windows. Ceiling heights follow the postwar norm — typically below the pre-war maximum but paired with brighter, more practical interiors. Higher floors gain open exposures over the surrounding low- and mid-rise blocks; light and outlook improve materially with altitude on this stretch of Lexington.
Building operations
1091 Lexington Avenue operates as a full-service postwar cooperative with door staff, elevator service, a live-in superintendent, central laundry, and private storage. The roughly 95-apartment scale supports a stable staffing model and the kind of low-key, residential operation that defines the better Lenox Hill postwar buildings.
The building maintains a no-pets policy, with service animals accommodated as required by law. As at most postwar co-ops on the avenue, the proprietary lease and house rules govern financing allowance, sublet, and pied-à-terre terms; a buyer's team reviews those documents as part of the board package.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign 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.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01411-0053) 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.
What to know if you’re buying
Central Lenox Hill location is the foundation. The 77th-and-Lexington position, with the 6 train at the door, is among the most walkable and transit-convenient on the Upper East Side.
Postwar plans differ from pre-war. Expect larger windows and efficient flow, with ceiling heights generally below the pre-war maximum — a practical, light-filled alternative to the corridor's pre-war stock.
Pricing is typically more accessible than the Park-block tier. Buyers can secure a strong Lenox Hill address here at per-square-foot pricing below Fifth and Park.
Note the pet policy. This is a no-pets building; animal-owning buyers should weigh that early.
Underwrite the apartment, not just the building. With a range of configurations across 16 floors, line- and floor-level comparable analysis matters more than building-wide averages.
What to know if you’re selling
Lead with location and convenience. Central Lenox Hill, walkability, and the 6 train at the corner are the headline for the building's buyer pool.
Price at the line and floor level. Exposure and altitude drive value dispersion; building averages understate the spread.
The full-service operation is a selling point. Door staff and a live-in superintendent distinguish the building within the postwar Lenox Hill set.
Closing timelines are co-op standard — generally 6–10 weeks from contract to closing, subject to board package and approval pace.

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.
