E. Guy Warren Hall, commonly known as Warren Hall, was a 13-story building at California State University, East Bay. It was the signature building of the campus, in the hills of Hayward, California, overlooking the East Bay region of the San Francisco Bay Area. The building was visible from cities throughout the Bay Area, and served as a landmark for Hayward and the East Bay. It was the tallest building in Hayward, followed by the abandoned City Center Building in downtown Hayward.

The hall was named for E. Guy Warren, a Hayward trucking businessman who helped convince the state to open its Alameda County campus in Hayward.[1]


Warren Hall implosion

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.[2] 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.[3][4] 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.[5] Today the now-demolished Warren Hall has become a parking lot and there are no plans whatsoever to build a new building on that lot.
