“In early 1939, the San Diego Electric Railway Company began the process of retiring the Class 1 streetcars. For a period of seven months that year, public sales were held to sell off the streetcar bodies, which could be purchased for $50 each.
“Fortunately, some of the big, roomy Class 1 streetcar bodies were purchased, put on lots, and converted into residences. Within a few months, however, there were complaints, and city leaders passed laws which made it illegal to use any more of the retired streetcars as residences…
“Since 1939, any time residential property with a streetcar home was sold in San Diego, the streetcar body had to be removed from the property, because they were not legally transferable as homes. The only streetcar bodies that could be used for homes were those that were grandfathered in, and continually resided in by the original property owner. Most streetcar homes were gone by the 1960s.
“A young, newly married couple purchased three of the streetcars in 1939 during that short seven-month period. This couple lived in them together for over fifty years. These are the last of the original 24 Class 1 streetcars and they are ready to be restored and returned the streets of San Diego.”
