Before San Juan Capistrano was established in 1776, the Los Rios Street Historic District and surrounding area was home to Native Americans of the Nation. In 1794, the first adobe homes for Mission neophytes and soldiers were built here, and some remain today, including the Rios Adobe, Montanez Adobe, and Silvas Adobe. Wood-frame structures began to be built in the late 1800's and into the early 1900's. The district is the oldest continually occupied residential street in California. Many historic families of San Juan were and are connected to the Los Rios area, including the Rios, Lobo, Ramos, Yorba, Labat, Olivares, and other families. The Los Rios Street Historic District was listed on the National Register of Historic Places in 1983.
