311 E 75Th St

A six-story pre-war cooperative erected in 1930, this boutique elevator building comprises roughly 60 studio residences spread over a narrow Upper East Side lot. The façade and massing reflect modest 1930s apartment-house proportions; interiors emphasize efficient single-room layouts with separate or pass-through kitchens in many units. Common elements include a staffed live‑in superintendent, a renovated lobby, a recently updated laundry room and video security; some units permit in‑unit washers. Large multi‑pane windows and high ceilings in several apartments provide significant natural light and tree‑lined street or planted-garden views. Building rules are conservative: pied‑à‑terres and dogs are typically prohibited, guarantors and gifting/co‑purchase policies are restricted or reviewed case‑by‑case, while subletting terms vary by tenure (ranging from one to five years before unlimited or board‑approved sublets). No exterior amenities beyond small private terraces or balconies under 60 sq ft are advertised. Located mid‑block on a quiet Upper East Side block near Citarella, Whole Foods and multiple transit lines (Q, 4/5/6 and buses), the property sits between Central Park and cultural institutions and benefits from dense neighborhood retail, gyms and restaurants.
