North Hills is one of the oldest communities in the Valley and was originally known as Mission Acres. After World War II, developers renamed the area Sepulveda. Northridge is to the west, Panorama City is to the east, Van Nuys is to the south, and Granada Hills to the north. Main thoroughfares include Lassen, Plummer, and Nordhoff streets, Hayvenhurst, Woodley, and Haskell avenues, and Roscoe and Sepulveda boulevards. North Hills is bounded by Balboa Boulevard and Bull Creek ("the wash") to the west, Lassen Street to the north, Sepulveda Boulevard on the east, and Roscoe Boulevard to the south.
In 1992, residents of the half west of the San Diego Freeway voted successfully to secede from the east in order to create the new community of North Hills. Sometime thereafter the value of apartment buildings and other rental properties between the San Diego Freeway and Sepulveda Boulevard fell. In 2008, management companies lobbied the City of Los Angeles to change the name of Sepulveda to North Hills. Thus, Sepulveda was annexed to North Hills. As a compromise to the residents of the original North Hills, the City of Los Angeles formed a new neighborhood of "North Hills West" which begins west of the 405 freeway and goes to Bull Creek/Balboa and from Roscoe to Devonshire.
North Hills West has a logo of a "tree in the city" was voted on by neighbors after over 20 entries and hundreds of votes. The slogan, Fostering Community, reflects the intent of the 2010 - 2012 Neighborhood Council. The 2012-2014 North Hill West Neighborhood Council was seated into office on September 20, 2012.
North Hills East formed a Neighborhood Council in 2012 and have a growing, bilingual group of neighbors dedicated to service.
The Sepulveda family for whom the community was formerly named has roots back to the founding of Los Angeles. Sepulveda Boulevard begins at the north end of the San Fernando Valley and extends all the way south to Long Beach, running through most of the populated section of Los Angeles County.
Northeast of North Hills is the old Spanish Mission and Pico Ranch House.
The small area varies a great deal; some parts of North Hills still preserve a small town feeling and are characterized by considerable neighborhood activism to preserve quality of life.
The area is home to the Sepulveda Veterans Administration and serves thousands of Veterans in the San Fernando Valley with an outpatient care, therapy and even a small golf course for Veterans.
