I went to the Oakland Public Library's Oakland History room to see if I could find out more about our building. The librarian there couldn't find anything but put me through to Betty Marvin: City Planner at the Oakland Cultural Heritage Survey. Up on the 3rd floor of the building downtown where you go to pay parking tickets, is her little office...an Oakland History enthusiast's dream which includes files on any building in Oakland of potential historical importance. So I sat down and read through the file she pulled for me on 1919 Market St.
The building was built in 1923 by the same architects that had done the Castro Theater (SF 1922) and would later do the Paramount Theater (Oakland 1929) as well as the Telephone & Telegraph building which was, at the time (1924) the tallest building in SF. One of the two architects also would be the lead consultant of the Bay Bridge (1936) design team.
The building was built as a storage/maintenance space for California Transit Co which in 1929 merged with Greyhound. My understanding is this building is the first home to Greyhound Bus Lines on the west coast/ birthplace of their west-coast section (Pacific Greyhound Lines). Greyhound was there until 1955 when a plumbing contractor Scott Co bought it. Not much information about after that, as I understand it's still owned by this plumbing company, but I'm unclear.
