The IAA (International Affairs Agency) Headquarters is a skyscraper in Grand Theft Auto V. It is the IAA's field office for the state of San Andreas. The building is located on the corner of Power Street and Swiss Street in Pillbox Hill, Downtown Los Santos, right next to the Federal Investigation Bureau Headquarters. It is based on the Two California Plaza, a 751-foot (229 m) skyscraper in Los Angeles, California. The building is the third tallest structure in Los Santos after the Maze Bank Tower and the Mile High Club, and is almost identical in height to the FIB Headquarters.
