  2. 1930

    Arthur Brown Jr. was commissioned to design the building, then planned as four storeys over a basement; the structural design was C. H. Snyder's and the mechanical plans Leland and Haley's. When the Depression stalled the job, the fifth floor and attic came off the McAllister Street wing and glazed, tooled terra cotta replaced granite on that front and around the courtyard.

  3. May 16, 1936

    The first purpose-built federal office building in San Francisco. Arthur Brown Jr., architect of City Hall, designed the four-storey granite-clad building around a central courtyard in the American Renaissance style to sit with the rest of the Civic Center. Ground was broken on 17 January 1933 before the money existed; the Public Works Administration granted $2,689,089 that August, construction began in early 1934 employing 300 men, and the building was dedicated on 16 May 1936. Staff of 33 federal agencies moved in. It was vacated in 2007 and rehabilitated in 2013.

  12. 1985

    On 27 October 1985 people living with AIDS chained themselves to this federal building's doors, where the regional Health and Human Services office sat - reckoned the earliest act of civil disobedience over the epidemic anywhere. The vigil that grew from it held the lawn outside day and night for ten years, and placards of the dead taped to these walls gave rise to the idea of the AIDS Memorial Quilt.
