Agoura Hills is the name of a California city, not a newly released work, so there is no single “release date” for something called Agoura Hills in the way there would be for a song or movie.

However, there are a few key dates people sometimes mean when they ask “when did Agoura Hills come out?”:

  • The community’s name “Agoura” was chosen in 1928, when residents formed a Chamber of Commerce and sought a permanent post office name.
  • The area had earlier names such as “Vejar Junction” and “Picture City” in the 1920s before “Agoura”/Agoura Hills stuck.
  • The city of Agoura Hills was officially incorporated on December 8, 1982, which is the closest thing to when “Agoura Hills” formally “came out” as a city.

So if you mean the city : it officially “came out” (was incorporated) on December 8, 1982.
