9902 3rd Avenue, Hamilton Gardens, is a postwar elevator co-op in the Fort Hamilton section of Bay Ridge, Brooklyn, NY 11209, set right on Third Avenue, the neighborhood’s main commercial spine. One of the larger co-ops in this part of Bay Ridge, it has 144 homes across six stories and is run as a well kept, professionally managed building. With an elevator, a full time live in superintendent, and no doorman, it offers the convenience of an elevator building at carrying costs that tend to run lower than a comparable full service doorman co-op.
The building is overseen day to day by a live in superintendent rather than a doorman, with a secure lobby and intercom entry. Residents have the use of an on site bike room, a card operated laundry room, and a storage room, and the building offers garage parking on a waitlist basis. Monthly maintenance covers heat, hot water, and real estate taxes. 9902 3rd Avenue is a pet friendly building that welcomes both cats and dogs, subject to a weight limit, which makes it a comfortable fit for buyers with a pet.
The location is one of the building’s strengths. The shops, restaurants, cafes, and lively festivals of Third Avenue are right outside the door, and the Shore Road promenade and the waterfront parks are nearby. The R train and the 95th Street station are a short distance away, the express bus to Manhattan runs nearby, and seasonal ferry service from Shore Road and 69th Street connects you to Manhattan and other parts of the city. Soldano Realty knows the building firsthand, so we can speak directly to how homes here live and what they sell for.
