In 1846, the area that is now Norco was part of a Mexican Grant from Mexico to Vicenta Sepulveda and was called the Little La Sierra Rancho. The area passed through several owners including the San Jacinto Land Company. James W. Long purchased the Norco area land around 1908. In 1921, the North Corona Land Company purchased the property. The name of Norco came from the North Corona portion of the company name. It was incorporated as a city in December of 1964.
