Armour & Co. Building
Also known as: 1050 Battery St.

Why it's listed
Built in 1907 at the corner of Battery and Union Streets in San Francisco, this load-bearing brick building served as a meat packing plant and smokehouse for Armour & Co., the Chicago firm that was then the nation's most powerful meat packer. It replaced an earlier warehouse on the site that was destroyed in the 1906 earthquake and fires. Architects Henry Geilfuss & Son, better known for Victorian houses, designed it with a rusticated base, brick pilaster-like piers and a corbelled cornice. Inside, heavy timber framing and the brick smoking ovens survive. The building matters as one of the few remaining structures from the time when Chicago's packers overtook San Francisco's local meat industry, and as probably the only surviving industrial work by its architects. Armour & Co. left in 1934, and the building now houses offices. Its exterior remains largely unchanged apart from ground-floor alterations.
Significance in brief: The nomination argues it is significant under Criterion A as a rare surviving building from the period when Chicago meat packing giants, led by Armour & Co., gained dominance over San Francisco's meat industry after the 1906 earthquake and the Meat Inspection and Pure Food and Drug Acts. Under Criterion C it is a late work of the locally prominent architects Henry Geilfuss & Son, apparently their only surviving industrial building, and an example of early twentieth-century warehouse architecture.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
