NO. 819 HUDSON'S BAY COMPANY HEADQUARTERS - On this block, then on Yerba Buena's waterfront, stood the California headquarters of the Hudson's Bay Company. Their chief trader, William G.

Inadequate profits, a declining fur catch, and pressure of U.S. expansion caused Hudson's Bay Company to end its California operations.
505 Montgomery Street
Although the guide shows the landmark to be at 505 Montgomery Street, we found the state plaque around the corner at: 605 Commercial St, San Francisco, CA 94111. (It is right across the street from CHL #87 Site of First United States Branch Mint in California)
