Building Description

There is no living space at 845 Union Street, but for residents of Brooklyn's Park Slope there may be no more desirable property in the neighborhood, as this is the only permanently deeded parking garage in Park Slope. While neighboring buildings are increasingly altered into more valuable apartment space, this seven-story parking tower has kept its intended purpose. The brick building was raised in 1928 and does not lack for original styling with its Art Deco vibe.

845 Union Street offers plenty of amenities, such as elevator access to cars, hand washing services, and 24-hour valet service. Regular condominium charges apply, including monthly maintenance fees and property taxes. However, not shoveling out during Brooklyn winters and avoiding parking tickets is a true luxury.
