After the City of Buffalo outgrew it's city hall (now Old County Hall), it was decided to build a new building at the current location at Niagara Square. Ground was broken on September 16, 1929 and the corner stone was laid May 14, 1930. The building was completed for occupancy on November 10, 1931 and was dedicated in July 1932 on the centenial anniversary of the city.
The building has 32 stories, 26 of which are usable office space, and is 398 feet high from the street to the tip of the tower. The total floor area is 566,313 square feet of which 316,937 square feet is usable for office space. There are 1,520 windows from the first to the twenty-fifth floor. An interesting design feature is that all of them open inward, making window washers obsolete in the new City Hall. It takes approximately ten days to clean them all.
