The Hobart Building was constructed in 1914 by San Francisco architect Willis Polk to replace an earlier building damaged by the 1906 San Francisco Earthquake and Fire. Polk designed the building French Renaissance Revival style with a three-part vertical division of base, shaft, and capital. It displays the mounted tower form of skyscraper design with a lozenge-shaped tower that rises from the center of the building.

The Hobart Building is San Francisco Landmark 162.
