Hacienda Heights (pronunciationⓘ) is an unincorporated suburban community in Los Angeles County, California, United States.

[4] Hacienda Heights sits on land that was originally part of Rancho La Puente.

[6] In 1912, his descendant, Anita Baldwin, sold the property to Edwin Hart and Jet Torrance.

[6] In 1913 the pair subdivided the area and named it North Whittier Heights, which became known for avocado, citrus and walnut orchards.

[7] However, from the Great Depression era to the early 1940s, citrus growing became unprofitable because of pests and diseases, setting the impetus for the area's transformation into a suburb.

[9] In 1960, the Hacienda Heights Branch of the Los Angeles County Public Library opened.

According to the United States Census Bureau, the community has a total area of 11.2 square miles (29 km2), of which only 0.06% is water.

There were 16,650 housing units at an average density of 1,488.9 per square mile (574.9/km2), of which 12,720 (78.6%) were owner-occupied, and 3,473 (21.4%) were occupied by renters.

Proponents argued that a new city would be able to better control development and provide increased police and fire service, while opponents argued that the new city would increase taxes and redevelop residential neighborhoods for revenue-generating businesses.

Most of the prime commercial land had already been annexed by the City of Industry to escape taxes levied by the County on unincorporated areas.

The festivities consists of rides, games, food, music and a grand raffle with cash prizes.

[46][47] Since the 1970s, there has been an annual football derby between rival high schools, Los Altos and Glen A. Wilson for control of a trophy that resembles a wagon wheel.
