After the Spanish founded Mission San Gabriel in 1771, the Chino Hills were used extensively for grazing by mission cattle. During the Mexican Republic era, the hills were used as spillover grazing from such surrounding Mexican ranchos as Santa Ana del Chino and La Sierra Yorba. After Mexico ceded California to the United States in 1848, the land was still used primarily for grazing.
This land was sold to Richard Gird, the founder of nearby Chino. With the building of the Carbon Canyon Mineral Springs in the modern-day Sleepy Hollow region of the city and the new Los Serranos Country Club in Los Serranos, Chino Hills, California, the area became a destination for both Los Angeles tourists and bootleggers during the prohibition because of its isolation. For the same reason, Sleepy Hollow became a destination for hippies and artists during the 60s. During the late 1980s, an incorporation effort began and in 1991, the city was incorporated with a population of 42,000.
Due to its topography of rolling hills, Chino Hills was primarily rural prior to the mid 1970s; most land was utilized for equestrian purposes and for dairies. Rapid and extensive housing developments followed throughout the 1980s and early 1990s, only slowing down in recent years. Most neighborhoods are arranged in a village-type format with strategically placed shopping centers and parks designed to be within walking distance of nearby homes.
Areas of the city adjoining the Orange County line are still primarily rural due to their relative isolation from transportation networks.
Chino Hills is home to the Vellano Country Club, a private golf course and housing development designed by golf champion Greg Norman, his first project in the Los Angeles area. With home prices expected to exceed $2 million, Vellano was touted (as of 2005) as the most expensive housing development in the Inland Empire, a region considered a bastion of affordable housing in the Los Angeles area.
Chino Hills is also the future location of The Shoppes at Chino Hills. Aside from featuring 40 upscale stores, and restaurants, The Shoppes will also be home to a new civic center, and up to 200 apartments and Live/Work townhomes.
There has been much controversy regarding The Shoppes, specifically among residents who frequently access Chino Hills Community Park. In order to build the center, the park had to be torn down. To alleviate the frustration expressed by residents, the City Council opted to move rebuild the park at a larger location about a mile away. 
The average home price in Chino Hills as of August 2006 is $623,758.
Chino Hills follows the Council-Manager model of government. The city is governed by a city council which establishes all city ordinances, approves plans, adopts budgets, etc. The council appoints the city manager who enforces laws and, in essence, runs the city's day-to-day operations.
The city council is elected by city residents and, within the council, rotates the position of mayor. Once elected, the city council members serve a four-year term. The five city council members meet on the second and fourth Tuesday of each month, with opportunity for residents to voice their opinion during the open forum. The meetings are broadcasted via the city's television station and streaming via the city's website.
Chino Hills does not have its own police department. Rather, it contracts with the San Bernardino County Sheriff's Chino Hills station. The Chino Hills station also serves the unincorporated area between Montclair and Chino, which includes an area known as Narod.
The city contracts with the Chino Valley Independent Fire District. The department has three stations located throughout Chino Hills.
Chino Hills is located at GR1(33.975267, -117.723054).
According to the United States Census Bureau, the city has a total area of 116.2 km² (44.9 mi²) much of which is undeveloped rolling hills including the Chino Hills State Park. 116.1 km² (44.8 mi²) of it is land and 0.2 km² (0.1 mi²) of it (0.16%) is water.
The city of Chino Hills is bounded by the Los Angeles County cities of Pomona and Diamond Bar to the north and to the northwest, the San Bernardino County city of Chino to the east, unincorporated Riverside County near Corona to the south and southeast, and the Orange County cities of Brea and Yorba Linda to the west and southwest, respectively.
The eastern border of Chino Hills is formed the Chino Valley Freeway (SR-71), which offers access to the Pomona Freeway (SR-60) to the north and the Riverside Freeway (SR-91) to the south. Undeveloped hills form the western border, which also serves as the San Bernardino - Orange County line. Because this area is mostly undeveloped, there is only one road directly connecting Chino Hills and Orange County, Carbon Canyon Road (SR-142), which is long, winding, and prone to landslides.
Chino Hills' main arterial roads are:
Chino Hills is generally divided into two sections: North Chino Hills and South Chino Hills. The border is usually considered to be the intersection of Chino Hills Parkway and Carbon Canyon (the area to the north and west of the intersection is north Chino Hills, the area to the south and east is south Chino Hills).
Most of the city is residential, and the few commercial areas are at the intersections of the arterial streets. These commercial areas are usually small community centers, anchored by supermarkets and fast food restaurants. The major commercial centers are at Chino Hills Parkway and Pipeline Avenue, and at Chino Avenue and Peyton Drive, where big-box retailers are located.

As is the case with adjacent hillside communities of Hacienda Heights, Rowland Heights, Walnut, and Diamond Bar, the upper-middle-class, often immigrant professional Asian American populations of Chino Hills are growing quickly. Such populations, including Filipino Americans, Chinese Americans, Korean Americans, Indian Americans, and Taiwanese Americans, are drawn by fairly new suburban sub-divisions in Chino Hills. As a result of this emerging demographic, the public library in Chino Hills has stocked some Chinese-language materials.
Chino Hills is served by the Chino Valley Unified School District, as well as a number of private elementary schools. It contains two regular high schools, Ruben S. Ayala High School (named after former California State Senator Ruben S. Ayala) and Chino Hills High School, and Boys Republic High School, a treatment center for troubled boys ages from 12 - 18.
Public transportation is virtually non-existent. However, Chino Hills has the OmniLink dial a ride service open to the general public. For $2.50 one way, one can travel throughout the city and transfer for free to the Omnitrans public bus at the Chino Hills Marketplace and the Chino Hills Civic Center. The dial a ride service operates five days a week, mostly during daytime hours.
