It is called an outstanding example of early California architecture from the transition after the missions. It was also home to Don Geronimo and Catalina Lopez, the city's first residents, and their descendants.","narrative":"Built in 1882-1883 by Valentino Lopez, this two-story adobe stands at the northwest corner of Maclay and Pico streets in San Fernando. Its walls are two feet thick, and porches with hand-cut railings wrap the front and both ends on the lower and upper levels. A tile roof added about 1928 replaced the original shakes. It was the first two-story adobe in the San Fernando Valley built as a residence, and it is regarded as the oldest remaining building in the city. Geronimo Lopez and his wife Catalina, among the first residents of San Fernando, later lived here after moving from Lopez Station, and the Lopez family's descendants kept the house until the early 1960s. The first newspaper in the valley was reportedly published in the house for a year in 1888. The nomination presents the house as an outstanding example of early California architecture from the period between the decline of the missions and the arrival of American settlers.","period_of_significance":"19th Century","architect_builder":"Valentino Lopez (builder)","architectural_style":"Early California adobe","criteria":[],"status_note":"Listed in good condition, altered, on its original site; described as in excellent physical condition needing minimal restoration, with interior apartments somewhat altered and modernized.
