520 East 76th Street (John Jay House)

Feldman's design rises 14 floors in red brick on a mid-block site, with the massing stepped back at the top two floors — the setbacks produce the building's signature penthouse product: angled bay windows, corner dens, and long wraparound terraces documented in the building's floor plans. Below, the 102 apartments run from studios through two-bedrooms, with post-war proportions — long living/dining rooms (some past 30 feet), enclosed windowed kitchens, and defined foyers — and ground-floor lines that open to patios on the garden side. South exposures over the low school buildings carry strong light; upper east-facing lines pick up river views toward the esplanade. Renovation quality varies by line, from estate condition to gut-renovated units marketed with stone baths and reworked kitchens.

Full-service at the essentials: 24-hour doorman, live-in superintendent, central laundry, bike room, and rentable storage, under institutional management (AKAM per city records). The outdoor program is the differentiator — the landscaped backyard with its deck, grill station, and lawn, and the common roof deck above — shared spaces that function as the building's amenity floor. There is no garage and no fitness center; buyers should weigh the outdoor space and service against the amenity stacks of larger post-war peers. Current financial statements, by-laws, and house rules should be obtained through the managing agent during diligence.

Recent sales

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01487-0039) 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.

The policy stack is the headline. Pieds-à-terre, sublets, pets, and 75 percent financing in one full-service co-op is a rare UES combination — it is why this building works for medical-corridor families, commuting professionals, and parents buying for adult children where stricter peer buildings do not. Verify each policy's current terms with the managing agent; the financing maximum appears as 75 percent in the building's marketing records and 80 percent in some brokerage records.

Walk the block before you decide. The cul-de-sac is the product: John Jay Park's pools and courts across the way, the esplanade at the end of the street, school-day rhythm on the sidewalk. Buyers who need subway-door convenience should price the walk — the Q at Second Avenue–72nd and the crosstown M79 are the practical links, and the FDR is immediate for drivers.

Underwrite the building, not the brochure. As with any post-war co-op of this vintage, the questions are the capital ones — facade cycles, elevators, boiler. Your attorney should review the last two years of financials and board minutes; we request them at offer stage as standard practice.

The penthouse and garden lines are different products. Setback terraces above, patio-and-garden lines below — both trade at premiums to the building's standard stack and rarely come to market. If one appears, the comparable set is other terraced post-war units, not the building's own mid-floor history.

Prepare the board package to the corridor's standard. Flexible policies do not mean a casual board. Run the Co-op Board Qualification Calculator before offering and structure the package accordingly.

Sell the flexibility to the widest pool. Pied-à-terre and sublet permissions materially expand who can buy your apartment — make the policies explicit in the marketing rather than leaving them to buyer-agent diligence. We confirm current terms with management before listing so the marketing claims survive attorney review.

Lead with the outdoor program. The backyard and roof deck photograph better than any peer amenity at this price tier, and the John Jay Park adjacency is a named asset — market the block, not just the unit.

Price to the east-of-York comp set. Anchoring to west-of-York post-war pricing overprices the unit; anchoring to walk-up Yorkville underprices the service. The correct comparables are the full-service co-ops east of Second Avenue, adjusted for the cul-de-sac premium. Renovated units clear at meaningful spreads here — run the Renovation Cost Calculator against your asking strategy if your unit is original.

The Roebling Team at Compass works the Upper East Side — including the east-of-York and hospital-corridor micro-markets — as a core practice area, and we have represented buyers at John Jay House; our offer materials from that work are part of the building file. We publish this building profile because buyers and sellers here deserve building-specific intelligence — policy verification, micro-market comparables, and block-level analysis — not generic neighborhood commentary.
