In 1841, Rancho San Dieguito, as it was originally named, was a Mexican land grant of 8,824 acres (35.71 km 2) from Governor Pío Pico of Alta California to Juan Maria Osuna, the first alcalde (mayor) of the Pueblo of San Diego. In 1906, the Santa Fe Railway, a subsidiary of the Atchison, Topeka & Santa Fe Railway, purchased the entire land grant to plant a Blue gum eucalyptus ( Eucalyptus globulus) tree plantation for use as railroad ties, but the wood proved too soft to hold railroad spikes. The railroad then formed the Santa Fe Land Improvement Company to develop a planned community of country estates, and 6,200 acres developed from the original Rancho San Dieguito land grant were renamed "Rancho Santa Fe" in 1922.

Rice worked through to 1927, designing, supervising, and constructing the village center, as well as several homes.
