A Private Pricing Opinion — what your apartment at 1003 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.
1003 Lexington Avenue is one of the most quietly exclusive small buildings in Lenox Hill: a 15-story pre-war cooperative with just 14 apartments — in practice, one full-floor home per floor. That configuration is the entire proposition. A buyer here gets the privacy and proportions of a private-floor residence, the discretion of a building where the elevator opens into your own foyer, and the service of a full-time-doorman cooperative — all on a corner of Lexington and 72nd that sits at the heart of the Upper East Side.
This is a building that trades on scarcity and format rather than headline amenities. Full-floor apartments in pre-war co-ops are among the most sought-after products on the East Side, and a building composed almost entirely of them — at a boutique scale, with white-glove service — is a genuine rarity. For the right buyer, 1003 Lexington is less a unit purchase than the acquisition of a floor in a discreet, well-run house.
Architecture and unit composition
Built in 1923, the building is a slender pre-war tower — 15 stories on a compact footprint, masonry over a limestone base, with a canopied Lexington Avenue entrance. The single-apartment-per-floor layout means each home enjoys exposures on multiple sides and the through-floor light that defines the most desirable pre-war residences.
The 14 full-floor apartments carry the hallmarks of the era at a generous scale: high ceilings, gracious entry foyers, separate formal and family spaces, and the room counts that pre-war full-floor living provides. With roughly 3,700 square feet of building area per unit on average, these are substantial homes — among the larger floor plates available in a building of this height. Private elevator-landing entry is the norm given the floor-through configuration.
Building operations
1003 Lexington is run as a white-glove cooperative. A full-time doorman staffs the canopied entrance, with resident building staff handling day-to-day operations, a fitness room, and private storage bins among the amenities. The single passenger elevator opening directly into private floors is itself a service feature, reinforcing the building's privacy.
The cooperative is pet-friendly. As is standard for a building of this caliber, purchases are subject to board approval and a conservative financing limit, and subletting is restricted in keeping with the building's owner-occupied, full-floor character. Given the scale — 14 shareholders — the board operates as a close, hands-on body; we walk buyers through its expectations as part of the purchase process. Confirm the current sublet terms and any flip tax with us before bidding.

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.

The retrade record
Lines that have traded more than once in the public record — the building’s appreciation arc, apartment by apartment.
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01407-0020) 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
This is a board-approval cooperative with a conservative financing posture, so come prepared with strong financials and a complete application; small, full-floor buildings underwrite buyers carefully. The product is the appeal — a private floor with multi-exposure light and pre-war proportions — and inventory is scarce, so be ready to move when a floor becomes available. The pet-friendly policy is a plus for the discerning buyer this building attracts. Underwrite to the building's financing limit and confirm sublet rules with us so your plans align with a building built around long-term, owner-occupied residence.
What to know if you’re selling
Scarcity is the story. A full-floor, multi-exposure pre-war home in a white-glove building of 14 apartments is exactly the product the top of the Lenox Hill market is hunting for, and the comparable set is the limited universe of full-floor pre-war co-ops on the East Side — not standard line apartments in larger buildings. Lead with the format, the light, the room count, and the discretion of the building; price to the scarcity of the product rather than to per-square-foot averages from buildings with very different layouts. The corner location at Lexington and 72nd, steps from the neighborhood's best retail and transit, reinforces the case.

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.
