The IAA (International Affairs Agency) Headquarters is a skyscraper in Grand Theft Auto V, located in Pillbox Hill, Downtown Los Santos, in the corner of Power Street and Swiss Street. It is located right next to the Federal Investigation Bureau building. It is based on the Two California Plaza building in Los Angeles, California, and is the IAA's field office for the state of San Andreas.
The IAA and FIB buildings are both government run agencies and are similar in design both in the interior and exterior of each skyscraper. The building has a total of 53 floors and most likely possesses similar features to the FIB building such as restricted and high-security areas in the highest floors. The rest of the building is most likely made up of offices. A large number of offices can be seen in Three's Company, as well as the 36th floor, which has a "Legal Affairs" section and a few offices.
Events of GTA V
- For the actual mission walkthrough, see Three's Company
Part of the inside of the building is seen in the mission Three's Company, where Michael De Santa, Trevor Philips and Franklin Clinton are forced by FIB agent Steve Haines to perform an abduction against the IAA in order to boost the funding for the FIB. During the abduction, Karen is seen torturing and beating Ferdinand Karimov, which implies she is working for the agency as a lead interrogator.
- Only the floor where the break-in from the mission is seen; the rest of the building is inaccessible.
- There is a glitch that allow you to get back inside the 36th floor out of missions. You have to parachute from high altitude then head for the second window (from right to left) as seen on this video. You should go through it and land in the building. You can notice that most of the building is poorly designed (except the office where Mr. K is tortured). Some walls are invisible and going through it will make you fall "inside" the building and teleport to a nearby street.
