Early development of the Menifee area began with Sun City in the early 1960s, conceptualized as an active retirement community by Del Webb, a building contractor from Phoenix, Arizona. Webb also developed Sun City, Arizona, under the same concept. Sun City is a centrally located neighborhood within Menifee with a mix of residential and commercial activity.
On June 3, 2008, the residents of the communities encompassing the Menifee area voted to incorporate together to form Riverside County's 26th city. The new City of Menifee was officially established on October 1, 2008
