Hayward’s much-anticipated, much-delayed downtown library will officially open on Sept. 14, the city announced. The $60 million project, funded through a voter-approved half-cent sales tax increase, had suffered a series of construction delays that bedeviled its completion over nearly two years.

A number of grand openings have been canceled over the years causing concerns among members of the public. Some residents were given a sneak peek at the library’s 58,000 sq. ft. interior nearly a year ago.

Next month’s opening, however, appears to be a sure thing. Last month, the city receive a certificate of occupancy to begin moving into the new library at 888 C Street.

The city approved the project in 2014 and construction began a year later. It was initially estimated to cost $40 million.

The project also includes a 25,000 sq. ft. open space adjacent to the library and Hayward City Hall to be called Heritage Plaza.

The city calls the downtown library the most environmentally-sustainable building ever built in Hayward. Entirely powered by carbon-free energy sources, the library is net-zero energy building. The library also features a cistern that will capture rainwater for non-potable uses and save 400,000 gallons of water a year.

Part of the recent delays in completing the library stemmed from a complaint the city made against an electrical company working on the project.

Over a number of council meetings this summer, the Hayward City Council was poised to remove the contractor from the project. Each time the agenda item was continued until last month when the city pulled its threat.
