Universal City is an unincorporated area within the San Fernando Valley region of Los Angeles County, California, United States. Approximately 415 acres (1.7 km²) within and around the surrounding area is the property of Universal Pictures, one of the six major film studios in the United States: about 70 percent of the studio's property is inside this unincorporated area, while the remaining 30 percent is within the Los Angeles city limits. This 70 percent portion of the property remains unincorporated in a county island to avoid the City of Los Angeles' business taxes and regulations (the community has a building permit office on site in order to simplify the building process).
Located within the area of Universal City is the Universal Studios Hollywood film studio and theme park and the Universal CityWalk shopping and entertainment center. Within the Los Angeles city limits are 10 Universal City Plaza, a 36-floor office building for Universal and NBC; the Universal feature animation studio; the Sheraton Universal; and the Universal Hilton. The Metro Red Line underground station of the same name is located opposite the 10 Universal Plaza.
A Los Angeles County Sheriff's Department (LASD) station is located at Universal CityWalk, and the community also houses the only government-funded fire station located on private property. The Los Angeles County Fire Department (LACFD) Station 51 (formally Station 60 until the mid 1990s) is of special significance to Universal, as "Station 51" was the fictional setting of the Universal and Jack Webb television series Emergency!. However, the current Station 51 was not used for external shots, or used as a model for the interior shots seen on the show (LACFD Station 127 in Carson, California was used).
Universal City's ZIP code is 91608, and the community is inside area code 818.
