For 40 years, Warren Hall was CSUEB's signature building; the building was visible from cities throughout the San Francisco Bay Area and served as a landmark for Hayward and the surrounding Eastern San Francisco Bay Area. Warren Hall was rated the least earthquake-safe building in the California State University system by the CSU Seismic Review Board. 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 the new 67,000 square foot-building began in November 2013, and doors opened in December 2015 on the completed structure.
