Located in the heart of San Francisco's Financial District, 101 California is a 48-story tower encompassing 1.2 million square feet of office space. 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 that contains seasonal flowers, seating and a fountain. 101 California was completed in 1982.
In 2011 and again in 2017, 101 California was certified at the Platinum level under the USGBC's LEED for Existing Buildings (EB) rating system. With a score of 94 leaf credits at that time, this architectural landmark earned the highest score ever awarded in the EB category throughout the world.
In 2023, 101 California underwent renovations on the lobby and plaza and developed new amenities for building tenants including a cafe, lounge, tenant-only workspace, and fitness center.
