York River House is the flexible-ownership value building of far-eastern Lenox Hill — an 18-story postwar red-brick tower at York Avenue between 63rd and 64th, converted in 1989 into a condop: a cooperative in which a co-op corporation (YRH Owners Corp.) owns the residential condominium unit, so shares are sold and financed like a co-op but the house rules carry the flexibility of a condominium. For buyers who want the accessibility and lower price point of a cooperative but not a traditional co-op's restrictions, the condop structure is the entire point of the building.
That structure is why York River House sells the way it does. A conventional far-Upper-East-Side co-op typically caps financing, prohibits pieds-à-terre, and restricts subletting to a few years. York River House, as a condop, permits pieds-à-terre, allows guarantors and co-purchasing and gifting, and runs a flexible sublet policy — while still transacting on a share-based, board-approval model with a co-op-style down payment. Priced on a per-room basis rather than per square foot, it is one of the more accessible full-service ownership options in the corridor, and the flexibility widens the buyer pool well beyond the traditional co-op purchaser.
Location is the honest trade. The building sits across from Rockefeller University near the East River, delivering water and garden views on its eastern lines and a quiet, institutional-campus setting — paired with a longer walk to the Lexington Avenue subway and proximity to the FDR Drive on-ramp at 63rd Street. Buyers who value the light, the views, and the price read the location as a feature; buyers who prioritize transit weigh it.
Architecture and unit composition
York River House is postwar red-brick pragmatism by Hyman Isaac Feldman, a prolific mid-century Manhattan apartment-house architect: an 18-story tower grounded in a rusticated two-story stone base, with efficient plans laid out for daily livability rather than grandeur. The eastern lines look toward the East River and the Rockefeller University grounds; some lines carry terraces and balconies.
The roughly 228 residences run from studios and one-bedrooms — which dominate the stock — through two- and three-bedroom homes. Layouts are classic postwar co-op plans: defined foyers, separated kitchens, and generous closets that renovate well. Because the building is priced per room, the studios and one-bedrooms are the building's currency, which makes it a natural first-purchase and pied-à-terre building given the flexible rules.
Building operations
York River House operates as a full-service condop: a full-time doorman, a live-in superintendent, an on-site full-service parking garage, a fitness center, a children's playroom, a landscaped rooftop terrace and garden, central laundry, a bike room, and private storage. The building is known for keeping maintenance moderate relative to full-service peers. The garage and any commercial income support the operating budget; buyers should review the financials, the reserve position, and any assessment during diligence, and confirm the current flip tax, sublet terms, and financing minimum with the managing agent — condop postures and fees can drift, and the exact figures are the building's most important transactional facts.

York River House trades as an accessible full-service condop, priced on a per-room basis, where the flexible house rules and moderate carrying costs drive absorption. Studios and one-bedrooms are the most liquid stock; eastern river- and garden-facing lines carry a premium over interior lines. The condop flexibility — pieds-à-terre, guarantors, co-purchasing, and a lenient sublet policy — widens the buyer pool relative to the traditional co-ops nearby. Recorded sales auto-populate from public records; unit-level history and current same-line comparables are maintained in The Roebling Research Library and shared with clients during diligence. Because the building is priced per room, same-line, same-room-count comparables are the correct analytical unit.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01458-7502) 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
Understand the condop structure first. A condop is a cooperative for financing and board-approval purposes but carries condominium-flexible house rules. That means a co-op-style down payment (approximately 20 percent) and board approval, alongside permitted pieds-à-terre, guarantors, co-purchasing, and flexible subletting. Confirm every one of those terms in writing with the managing agent. Run the Co-op Board Qualification Calculator before offering.
The flexibility is the reason to be here. Few full-service buildings on the far Upper East Side permit pieds-à-terre and lenient subletting at this price point. If that flexibility matters to your plan, it is the building's core value — verify current policy.
Price per room, not per foot. As a per-room cooperative, the studios and one-bedrooms are the currency. Use same-room-count comparables. Run the True Monthly Carrying Cost Calculator on the specific unit.
Underwrite the location honestly. Across from Rockefeller University near the river: light, garden and water views, and quiet, but a longer walk to the Lexington line and proximity to the FDR on-ramp. View the specific line at multiple times of day.
What to know if you’re selling
Sell the flexibility. The condop rules — pieds-à-terre, guarantors, co-purchasing, flexible subletting — are the building's differentiator against the strict co-ops nearby. Market them directly to the buyer who needs them.
Sell the carry. Moderate maintenance relative to full-service peers is a headline buyers respond to. Document it.
Position the views and the price. Eastern river- and garden-facing lines and the per-room accessibility are the marketing story. The location trade is best framed as light, quiet, and value.
Document the structure proactively. Buyers' attorneys will want the condop mechanics — the financing minimum, sublet terms, and flip tax — confirmed early. Providing them shortens diligence.
