PBA Galleries roots lie with Maurice Powers who founded the California Book Auction Galleries in 1955, located at 139 Townsend Street, San Francisco, California. After Maurice Powers passed away in 1990, the company was placed in voluntary bankruptcy by his heirs.
The former employees of California Book Auction Galleries, including Bruce MacMakin, in 1992 founded Pacific Book Auction Galleries located at the old premises of the auction house. In 1996 the auction house relocated to the center of San Francisco, at 133 Kearny Street.
In 2013 the auction house was purchased by the current owner and booklover Sharon Gee. After continued growth the auction house moved in 2019, to 1233 Sutter Street, San Francisco, and finally to its current location at 605 Addison Street in Berkeley.
