History and Architecture

Constructed in 1936, the building served 74 years without a major renovation and survived a catastrophic earthquake. It is listed on the National Register of Historic Places as a contributing building to the San Francisco Civic Center National Historic Landmark District. In 2017, the building was added to the National Register of Historic Places as a standalone building under categories A and C. The building's original architect, Arthur Brown, Jr., was a prominent San Franciscan and also the designer of San Francisco City Hall and the San Francisco Opera House.

The Architect of Record for the renovation was HKS, Inc.

Renovations included environmental remediation; new mechanical, electrical, lighting, and plumbing systems; roof replacement and refurbishment of existing historic wood windows; and restoration of the historically significant interiors and central courtyard as well as redesign of office interiors.


With renovations completed in 2013, the building achieved a LEED® Platinum rating from the U.S. Green Building Council and has won prestigious design and reconstruction awards:
