The City of Hayward opened the
steel reinforced concrete building on October 18, 1969. It was originally planned to have 20 floors and a cinema, but only 11 floors were built, with no cinema. The building served as Hayward's city hall from 1969 to 1998. Its top floor was the seat of municipal government and other floors were leased to businesses. It was designed to replace the old Hayward city hall, now located at
Alex Giulini Plaza. It was the first building in the planned City Center complex. Architectural critic
Allan Temko nicknamed the building "the toaster" in the 1970s, strongly influencing public opinion against it. The
Centennial Hall Convention Center was added to the complex. In the 1980s, the PlazaCenter complex of retail and commercial businesses was built next to it, on the former grounds of
Hayward High School. The
1989 Loma Prieta earthquake damaged the building's structural integrity and the city government moved out of the building.{{cite news | last = O'Brien | first = Matt In 1998, after the completion of the new city hall, the building was closed to the public. The city sold the building for $1.5 million in 1998 to a developer who planned to convert it to
condominiums. They renamed it "Centennial Tower" and sold it to another developer. Condominium conversion was never implemented, as it was considered too expensive. In 2006 plans were made to demolish the building. A year later, the demolition was canceled. On November 1, 2009, the adjacent Centennial Hall Convention Center closed, and was subsequently demolished. == New Hayward City Hall ==
