The DHD Office is located in Union Square, which is an important and historic intersection in Manhattan in New York City, New York. It is located where Broadway and the former Bowery Road – now Fourth Avenue – came together in the early 19th century. Its name celebrates neither the Federal Union of the United States nor labor unions but rather denotes that this was the union of the two principal thoroughfares of the island of Manhattan.
