315 W 99Th St

An eight-story Renaissance Revival co‑operative on the Upper West Side, completed in 1920 and converted to co‑op ownership in the early 1980s. The building contains about 20–33 residences (representative listings reference 20–33 units) configured primarily as two‑ and three‑bedroom apartments, including duplexes and penthouse layouts with significant private outdoor space. Typical homes retain pre‑war details: high ceilings, hardwood floors, generous foyers, built‑ins and ample closet storage; many units have been renovated with modern kitchens and bathrooms while preserving period character. Common areas are well maintained and include a renovated lobby, card‑operated laundry room, building roof deck and individual storage rooms; some units convey large outdoor storage lockers. Resident services feature a daily part‑time doorman (roughly 7:30am–midnight or later), a live‑in superintendent and a porter; bike storage and elevator service are also available. The co‑op has pet‑friendly policies and flexible board practices in many listings, allowing co‑purchasing, gifting and pied‑à‑terres on a case‑by‑case basis. Located on a tree‑lined block between West End Avenue and Riverside Drive, the building sits steps from Riverside Park with convenient access to 1/2/3 express trains, local buses and nearby neighborhood shopping, groceries and restaurants.
