Site[edit]
The building is located at 1355 Market Street,[1][2] occupying the length of the city block between Ninth and Tenth Streets, bounded on the other side by Stevenson Street.[3] This places the building in San Francisco's Mid-Market neighborhood,[3] which is bounded by Fifth Street, Market Street, Mission Street, and Van Ness Avenue,[4] in the city's central business district.[5] Historically, this area around the site on Market Street was a theater district occupied by numerous theaters and movie palaces during the early 20th century, such as the Fox Theatre, which was situated across the street from the building.[3][6]
