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 from the Hayward Fault. In January 2013 the CSU Board of Trustees authorized $50 million to demolish the former administrative building and replace it with a new structure. Warren Hall was demolished by implosion on August 17, 2013. Construction for a new 67,000 square foot-building is expected to begin in November 2013. Doors are expected to open in May 2015 on the completed structure.
