The first tract homes went up in 1960, right next to where the Pomona Freeway (60) would later pass. The town's development and population grew extremely fast after that.
Transamerica oversaw all development of the community through the 1960s. The Transamerica Corporation divested itself of all its real estate ventures in the 1970s and 1980s. As a result, the Diamond Bar project was sold to multiple developers and much of its initial master plan was not implemented during the latter half of its development in the 1980s
