IAA Building

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.

FIB Agents Steve Haines, Dave Norton, and Andreas Sanchez have Michael De Santa, Trevor Philips, and Franklin Clinton kidnap Ferdinand Kerimov from the IAA Building while he is being interrogated. Trevor flies a helicopter to the IAA Building, while Michael rappels from the helicopter to the 36th floor to take Kerimov. Franklin sets up across the street to provide long range sniper support while Michael takes Kerimov into custody.


  • While the FIB and IAA Buildings are based on California Plaza, the curtain wall of both buildings is based on the Aon Center.
