The original hospital , located at 1200 State Street , opened in 1923 . Its art-deco construction earned it the nickname the Great Stone Mother and had 800 patient beds . The 1994 Northridge earthquake on January 17 , 1994 renewed concerns about building safety codes , and specifically those for hospitals . The California Hospital Seismic Safety Law was signed into law on September 21 , 1994 . The new law took the 1200 State Street building out of compliance of earthquake and fire safety codes
