In addition to the stores and workshops that occupied the interchangeable spaces that predominated on the ground floors of the main streets in North Beach, there were other businesses established before 1921 which by their nature or their size, did not fit in a standard commercial space. The largest of these were located at the north end of the district: the Bauer & Schweitzer Malting Company (Landmark No. 129) at 530-50 Chestnut Street and the Lewis Packing Company Vinegar and Pickle Works at the corner of Columbus Avenue and Chestnut (demolished). Both were large industrial plants served by rail spurs of the Belt Railroad, linking them to the port, with specialized tanks, sheds, and other structures on large sites. North of Francisco Street, outside the survey area was an extensive industrial zone associated with the port, and drawing much of its labor from North Beach.
