History:
 
The Los Angeles Signal Depot facility was consolidated in 1943 from several sites located within and outside California. The Depot evolved from two antecedent installations. One of the installations was the San Bernardino Signal Depot. The original building utilized by the Signal Depot in San Bernardino was closed at the end of 1942. In early December 1942, warehouse space was obtained at 831 South Alameda Street in Los Angeles and all operations of the San Bernardino Signal Depot were moved to that site. The name of the facility was changed at that time to the Los Angeles Signal Depot. The other antecedent installation was the Dayton (Ohio) Signal Depot, from which four employees were sent to San Pedro, California to establish a new facility.
 
The initial facility operated from June 1, 1942 to May 13, 1943. Operations were then moved to 1388 East Seventh Street in Los Angeles. The Dayton Signal Depot, Western Branch was opened at the Seventh Street location on June 1, 1943. The Dayton and Los Angeles Signal Depots subsequently were consolidated at 1388 E. Seventh Street on October 5, 1943. The Los Angeles Signal Depot was designated as a backup depot for the Los Angeles Port of Embarkation. The depot furnished Army Ground Forces equipment to California south of King City, to the Desert Training Center, to Los Angeles Sub-Port of Embarkation, and to Land-Lease for Mexico. The area of service was modified to include the states of Arizona and Nevada at various times. Subsequently, equipment maintenance and repair was performed onsite.

Other tasks were to supply the entire Army with meteorological equipment and supplies, to act as backup depot of the Air Services Command, to handle repairs to all radio equipment (including classified equipment), and to exchange defective equipment with airplane manufacturer's plants. As hostilities with Japan ceased at the end of World War II, the mission of the Depot was modified to focus mainly on the disposal of surplus supplies.
 
The 7 May 1946 Army of the United States Stion List shows that the site was in a "Surplus" status. The depot was closed in 1946
