Chino Hills was incorporated in 1991, and most of its homes were built in the 1980s and 1990s during Southern California's suburban expansion. That timing means the majority of the city's original fencing is now 30 to 45 years old - far enough along that post rot, loosened footings, and warped boards are common throughout entire neighborhoods at once. The city is built across rolling hills in the Puente Hills and Chino Hills ranges, which means many properties have sloped backyards, tiered outdoor spaces, and retaining walls along their perimeters. Fencing on these lots requires more planning than a standard flat installation - panels need to follow the grade, drainage has to be considered, and post depths vary depending on where on the slope you are digging.

Chino Hills also has a meaningful wildfire exposure. Parts of the city are designated Very High Fire Hazard Severity Zones by CAL FIRE, and the dry Santa Ana winds that push through the area each fall create conditions where homeowners in these zones think carefully about what materials they put near the brush-facing sides of their property. The clay-heavy soil throughout the city expands and contracts with every wet and dry cycle, which gradually loosens fence footings even when the installation was done correctly the first time.

Chino Hills was incorporated as a city in 1991 and sits in the Puente Hills and Chino Hills ranges in San Bernardino County, bordered by Orange County to the south and Los Angeles County to the northwest. With a population of roughly 82,000 to 85,000, it is one of San Bernardino County's larger cities, but it has no traditional downtown and is almost entirely residential in character. Median household income well above $100,000 and median home values past $700,000 make it one of the wealthier mid-size cities in the Inland Empire. Most residents are long-term owner-occupants who commute to jobs in Los Angeles, Orange County, or the broader region. The housing stock is predominantly single-family stucco homes built in the 1980s and 1990s on lots that range from modest to mid-size, many with sloped or tiered backyards owing to the city's hilly terrain. Neighborhoods spread across the hills, with streets that wind rather than grid, and views that extend across the valley.

Chino Hills State Park runs along the city's western edge and gives many neighborhoods a direct view of open grassland and oak woodland. Carbon Canyon Regional Park on the eastern side of the city is known locally for its grove of coastal redwood trees. The main commercial area is centered around Grand Avenue near The Shoppes at Chino Hills. Adjacent communities include Diamond Bar to the east and Pomona to the north, both of which we serve as well.
