There was a workplace shooting in this building in 1993. A disgruntled client entered a law firm and killed eight people.

The tower is cylindrical in shape with articulated edges of alternating bands of granite and glass featuring a seven-story, glass enclosed lobby at its base, and a granite paved triangular plaza which contains seasonal flowers, seating and a fountain.

Located in the heart of San Francisco's financial district, 101 California is a 48-story tower encompassing 1,200,000 square-feet of office space.

Tower's entrance reminds one of the main entrances of 101 Park Avenue, another work by the same architect, and completed the same year in New York.

The Spreckels Building formerly stood at the southeast corner of this site.
