Houses that went up almost at once
Cerritos incorporated in 1956 as Dairy Valley, a town of about 4,000 people and 120,000 cows, LAist reports. A zoning change in March 1965 allowed denser housing on smaller lots and opened the way for large-scale building, and the city took the name Cerritos in January 1967. Census estimates put the median year built at 1974, and about 80% of homes are detached houses. Original supply lines and drains from that building wave are now roughly 50 years old.
