The Leonis Adobe, built in 1844, is one of the oldest surviving private residences in Los Angeles County and one of the oldest surviving buildings in the San Fernando Valley. Located in what is now Calabasas, California, the adobe was occupied by the wealthy rancher Miguel Leonis (October 20, 1824 – September 20, 1889) until his death. Following Leonis' death, the property was the subject of a legal dispute between his common law wife Espiritu Chijulla (1836 – May 10, 1906), heirs, and a daughter born out of wedlock; the dispute lasted more than 15 years in the courts. In 1961, the adobe had fallen victim to vandalism, and its owner applied for a permit to raze the structure and erect a supermarket in its place. Preservationists succeeded in having the adobe declared Los Angeles Historic-C
