Chet Holifield Federal Building

The Chet Holifield Federal Building, colloquially known as "the Ziggurat Building", is a United States government building in Laguna Niguel, California. It was built between 1968 and 1971 for North American Aviation/Rockwell International, and designed by William Pereira. Since 1974, it has been owned and managed by the General Services Administration. National Archives and Records Administration had holdings for the Pacific region stored here, but has since moved to another location. Primary tenants are now regional offices of the United States Department of Homeland Security and the Internal Revenue Service.
