The Russell Warren House is one of the best examples in scale and detail of a flat-front Italianate Victorian in San Francisco. It was built about 1875 by a noted San Francisco architect and builder of post Gold Rush era, Russell Warren.

With an elegant and simple facade, the building makes the point of permanence by recalling the glory of modified Renaissance and Mannerist Italian palaces. As a residence it fits the close functional and fashion relationship of buildings made high and narrow because of lot limitations and because of regard for high-ceiling interiors at this time, with high and narrow door and window openings related to the basic building shape.

Few flat front Italianate residences remain in San Francisco as most were East of Van Ness Avenue and did not survive the 1906 Earthquake and Fire.
