The IAA Building is a high-rise federal building and the west coast headquarters for the International Affairs Agency, located in the Pillbox Hill neighbourhood of Los Santos in Grand Theft Auto V. Loosely based on One California Plaza, it is one of the tallest buildings in the Los Santos skyline. Its design is similar to the FIB Building, and the two buildings share a common plaza.
