The hall was named for E. Guy Warren, a Hayward trucking businessman who helped convince the state of California to open its campus in Hayward.[1]
The building held administration offices and classrooms for 40 years.[2] The president's office was on the top floor and had extensive views.[citation needed]
Demolition
Warren Hall was rated the least earthquake-safe building in the California State University (CSU) system by the CSU Seismic Review Board. It was built 2000 feet (600 meters) from the Hayward Fault.[3] In January 2013, the CSU Board of Trustees authorized $50 million to demolish the building and replace it with a new structure. Warren Hall was demolished by implosion on August 17, 2013.[4][5] At the time, construction for a new 67,000 square foot-building was expected to begin in November 2013, with doors expected to open in May 2015.[6] Today the now-demolished Warren Hall has become a parking lot, and there are no current plans to build a new building on it.
Seismic research
The implosion of Warren Hall provided a scientific opportunity to learn more about the Hayward fault.[7][8]
