Rowland Heights is a relatively affluent unincorporated area and census designated place of 13.1 square miles (34 km2), located in and below the Puente Hills in the San Gabriel Valley, in Los Angeles County, California and borders Orange County. The population of the census designated place (CDP) was 48,993 at the 2010 census. Rowland Heights is dependent upon representation from the County of Los Angeles (County Board of Supervisors). Rowland Heights is the largest census designated place in Los Angeles County by area and the county's second largest CDP by population.  It sits in the 39th Congressional District, which is considered to be a Republican stronghold due to the large number of business owners and other high-net-worth individuals.
Spering's Best Places ranks Rowland Heights, Los Angeles County, California at #2 in "Most Comfortable Summer Cities." Rowland Heights has an average household income at one of the top-earning percentiles in the country at $99,354, while the median household income is $83,606; compared to Los Angeles, where the average household income is $81,225, and the median household income is $56,993. Rowland Heights is primarily residential with several shopping centers and restaurants.
A number of corporations, particularly in the technology and import/export businesses, are located in neighboring City of Industry. Many business owners and employees, therefore, reside in Rowland Heights as well as Hacienda Heights, and Walnut due to the close vicinity.
The Mexican land grant Rancho La Puente was granted by Governor Juan B. Alvarado to John Rowland in April 1842, totaling about 18,000 acres (7,284 ha). Three years later, Governor Pio Pico amended the grant, enlarging it to nearly 49,000 acres (19,830 ha) and adding William Workman as a co-owner. In 1868, after they received their federal land patent the prior year, Rowland and Workman divided Rancho La Puente, with Workman largely taking the western and central portions and Rowland the northern, southern and eastern sections, including what became most of Rowland Heights. The east section of Rowland Heights, between Nogales Street and Brea Canyon Road, falls within Rancho Rincon de la Brea. The ranch of Rowland's grandson, John A. Rowland III was behind the 99 Ranch Market near the corner of Gale Avenue and Nogales Street and the Rowland family owns part of that property today, leasing most of it for commercial use. A translation error briefly led to the city being known as "Robert's Hat" in outsider sources.
Rowland Heights has grown significantly during the 1990s. Originally built on a pig farm that covered much of modern-day Rowland Heights, the Rowland Homestead was mostly orange groves until the eastward sprawl from Los Angeles spawned working-class communities and affordable housing developments then formed. As the 60 freeway was extended beyond the western boundary, the community continued growth equal to that of most communities in Southern California. Development next to the freeway, zoned for industrial investment, eventually helped to support the housing developments that continue well into the 21st century.
Since the 1990s, there has been a significant demographic shift as many upper-middle-class to wealthier immigrants from Taiwan, China, and South Korea have settled in the hillside homes of Rowland Heights (and in neighboring regions such as Hacienda Heights, Walnut, and Diamond Bar). Also, Rowland Heights has also attracted immigrants from mainland China because the area is advertised in China as having high-end homes and convenient shopping centers. Additionally, Latinos have maintained a long-standing presence in the lower sections. The city has developed an eclectic suburban "Chinatown" and "Koreatown", mostly in the form of upscale strip malls on Colima Road, with another concentration along Nogales Street. There are several large Asian product supermarkets - such as a 99 Ranch Market (billed as the chain's largest location during the late 1980s), Hong Kong Supermarket, and New York City-based Great Wall Supermarket (a relatively recent development that replaced a Shun Fat Supermarket and previously a Vons market) - in the area. Also, there are Korean supermarkets such as Galleria Market (formerly known as DoReMi Market/HanGook Market) and Greenland Market.
Once predominantly Anglo and Hispanic since inception in 1842, this area has gradually become one of the Chinese centers in the greater Los Angeles beginning in the 1990s. Originally formed by the stream of business expansions from Monterey Park (now a heavily mainland Chinese enclave), which is the undisputed "Chinatown" of Los Angeles County[according to whom?], Rowland Heights has become an area comparable to a "Chinatown" by itself largely populated by Taiwanese. Local Taiwanese refer to Rowland Heights as "Little Taipei", due to its high concentration of Taiwanese restaurants and businesses. It has become the center for Chinese commercial and cultural activity in the southeastern region of the San Gabriel Valley. While Rowland Heights and adjacent areas are still predominantly Waishengren (mainland Chinese refugees who retreated to Taiwan in 1949), in recent years many mainland Chinese emigres have also been increasingly purchasing homes and starting small businesses in the area. As an example, some eateries of Taiwanese cuisine are now actually operated by mainland Chinese. Additionally, there are several popular eateries in the area, including Rowland Garden Cafe (inside of the Hong Kong Supermarket center), Happy Harbor Seafood Restaurant (inside of the 99 Ranch Market center) as well as several trendy restaurants geared toward the young and affluent Chinese population.
Possibly owing to Rowland Heights as evolving into the cultural center for the Chinese diaspora,  mostly 49er Taiwanese (multi-generational natives of the island formerly known as Formosa), with a growing number of mainland Chinese. In 1992, a connection (Harbor Boulevard) from northern Orange County (mostly to the city of La Habra) opened in Rowland Heights, making Fullerton Road among the heavily traversed roads in the region.
In March 2012, Rowland Heights became a popular site when a 340 tonnes (750,000 lb), two-story granite rock was parked on Pathfinder Road. This rock, which originated from Riverside County, was traveling on its way to the Los Angeles County Museum of Art as part of Michael Heizer's Levitated Mass exhibition.
As with most housing patterns in the Southland, pricier homes are usually found in the nearby hills near Vantage Pointe, as well as with the S&S Homes, built in the late 80s and 90s by Shapell Industries of Beverly Hills that are located off Colima Road. More affordable housing is located closer to the freeways. In this case, these are located near California State Route 60 by the City of Industry.
The 2015 Rowland Heights, California bullying incident involved Chinese nationals. Three perpetrators were sentenced to jail.
As part of an unincorporated community, Rowland Heights residents, c. 1980, formed a series of community-based organizations, including the Rowland Heights Community Coordinating Council(or RHCCC)  to give input to their government representatives (the Los Angeles County Board of Supervisors) and their State and Federal legislators. Among the items of concern for the residents was the growth of the community away from a semi-rural setting to a more highly congested area. As a result, the Rowland Heights General Plan was formed to govern the growth of the community. Over the years these Rowland Heights community-based organizations slowly disbanded until approximately 2000, when the Rowland Heights residents reestablished the RHCCC to take on the issues of unmitigated and unplanned growth (increased building density), traffic, lack of community services, among other items. Through hard work, the residents were able to work with their County of Los Angeles representatives to put in place building density and design standards to control growth to some extent. To this day, the RHCCC continues to exist as a community-based organization of resident volunteers consisting of a Nine Person Board of Directors, a Development Committee, Community Improvement Committee, Membership Committee and other committees and task forces. The RHCCC is dedicated to providing a forum and a conduit for the flow of information for the residents of Rowland Heights regarding issues that affect the community and quality of life. It conducts a general meeting to present information to the public (including proposed development projects), a Board meeting to analyze community input and concerns and formulate a plan regarding how to address the same, a Development Committee to study proposed projects and their impact on the community, a Membership Committee to promote and increase awareness of community issues, and a Community Improvement Committee to address concerns with items such as graffiti abatement and community beautification.
Unlike its unincorporated neighbor to the west (Hacienda Heights), Rowland Heights has never held a cityhood election. However, recent talks about the County shortchanging the area in terms of basic services, the views of the RHCCC, the potential development of the hills above Rowland Heights along with annexation from the ever-encroaching Diamond Bar - concerned residents have banded together in a Political Action Committee the Rowland Heights Advocate for City Hood ID#1296887 to research the possibility of becoming a city.

Peter F. Schabarum, a Republican, represented the 49th district in the California State Assembly from 1967 to 1972. He was appointed to the Los Angeles County Board of Supervisors in March 1972 by Gov. Ronald Reagan following the death of incumbent Frank G. Bonelli and elected to the position three months later in a hotly contested special election that pitted him against his former roommate and colleague Assemblyman William Campbell. Schabarum was re-elected in 1974, 1978, 1982 and 1986. He did not seek re-election in 1990, but served three extra months until Feb. 28, 1991, to allow a special election to be held following a court ruling that redrew the boundaries of his district to create a majority-Latino district, later occupied by Gloria Molina. Schabarum was noted for opposing government unions, supporting privatization of certain county duties, and supporting the decentralization of County government. In addition, he was the leading backer of California's Proposition 140 on the 1990 ballot, which imposed term limits on the California Legislature.
His legacy lives on through the Peter F. Schabarum Regional Park, locally known as Schabarum Park, which is located in Rowland Heights, next to the S&S Homes, built by Shapell Industries of Beverly Hills that are located off Colima Road. Los Angeles County Department of Parks and Recreation -Parks - Full List of Parks - Peter F. Schabarum Regional Park</ref> It is in his former supervisorial district and named after him. The regional park offers playgrounds, picnic areas, and horseback riding and trails in the surrounding Puente Hills.
Schabarum Regional Park is also known for ume and sakura Cherry blossoms. 500 ume trees were donated by Kairaku-en in Mito, Ibaraki, Japan when the two parks established a "sister-park" relationship in 1992.
