San Fernando Building, Renaissance Revival office building in Historic Core district, Los Angeles, United States

The San Fernando Building is a Renaissance Revival office building in the Historic Core district of Los Angeles with Mediterranean influences. Its lobby features a 22-foot ceiling, ornate cornices, and exterior panels decorated with an incised diamond pattern.

The building was commissioned by businessman James Boon Lankershim in 1906 and designed by architect John F. Blee. Its completion in 1907 marked a period of commercial expansion in the downtown district of that era.

The building's name comes from the San Fernando Valley landholdings of James Boon Lankershim, whose father owned much of the valley; the family name traces to Rancho San Fernando. In 1908 the California Colony and Home Promoting Association, formed by Lt. Col. Allen Allensworth and Dr. William A. Payne, opened an office here to promote the Black-settled town of Allensworth in Tulare County.

The building was converted into residential lofts in 2000, preserving its historic details while enabling modern living in downtown Los Angeles. The location is easily walkable, and the downtown setting provides good transit connections and nearby amenities.

In October 1913 a fire started by an overheated motor in Unit 110, home of the California Film Exchange, destroyed some 150 motion pictures; two explosions followed when flames reached stored chemicals. Three people, including a fireman, were hospitalized, and the night operator of the physicians' telephone exchange upstairs barely escaped. The blaze prompted calls to ban flammable film stock from downtown office buildings.
