Following the disastrous San Francisco Earthquake and Fire of 04/18/1906, building developers searched for architects who could deliver earthquake-resistant buildings. Charles F. Whittlesey (1867-1941) presented himself as an expert in reinforced concrete architecture, and received the commission for the Pacific Building, a highrise in the heart of the Market Street business district. Whittlesey also received the commission for another highrise close by, the flatiron shaped building at Market and Ellis Streets.

Building Notes

The Pacific Building, located at the southwest corner of Market Street and 4th Street, stood immediately to the northeast of the Emporium Department Store #2, finished one year later. This portion of San Francisco was heavily damaged in the Earthquake and Fire of 04/18-19/1906.

In 1925, the Massachusetts Protective Association leased space in Room #531 of the Pacific Building. H.C. Bradbury was the State Manager at the time. (See San Francisco, California, City Directory, 1925, p. 1275.)


Gensler Associates supervised a renovation of the Pacific Building.
