4 W 109Th St

The Parkside at 4 West 109th Street is a six-story pre‑war co-op originally built in 1890 and converted to cooperative ownership in the late 20th century. The 41‑unit elevator building retains period character—high ceilings, hardwood floors and classic moldings—alongside a series of modern upgrades such as centralized heating improvements and upgraded electrical systems. Residences are primarily one‑bedroom layouts with efficient circulation, generous closets, and features found in many units including windowed kitchens, marble or stone bathroom finishes, walk‑in storage, ceiling fans and occasional first‑floor bedroom arrangements. Common areas are well-appointed for neighborhood living: a large south‑facing roof deck with grill and private roof spaces, a fitness room, children’s playroom, communal laundry, bike room and storage facilities. The building operates with a part‑time doorman/super and maintains low monthly maintenance charges; a flip tax applies. Policies are flexible for a co‑op: pets are permitted, pied‑a‑terre ownership is allowed and subletting is available under the board’s guidelines. On‑site practicalities include elevator access, basement storage and central vacuum provisions in some units. Situated on a tree‑lined block half a block from Central Park and one block from Morningside Park, the address offers immediate access to B/C trains at the corner plus nearby 1/2/3 lines, neighborhood grocery options and a broad roster of restaurants and shops serving the Upper West Side and Manhattan Valley.
