The Mendez Building, or alternatively called the Mendez Foundation, is a skyscraper and a headquarter for the Mendez Cartel in Grand Theft Auto: Vice City Stories, during 1984. The building is located in Downtown and most likely used to hide drugs smuggled into the city by the Mendez brothers. The building is east of the Hyman Memorial Stadium and across the Hyman Condo. The flying height limit in Vice City Stories is up to the roof of the building making it a great spot for players to steal Police Mavericks mid-air while being chased by one. Even though the player can clearly see through the building and the elevators, they can't be used and the only floors visible are the top two ones. Using a Little Willie is an easy way to get into the interior. On the bottom part of the building is a health pickup available.
The building's most notable appearance is during the final storyline mission of GTA Vice City Stories, Last Stand, in where Victor Vance first launches an air attack on the building with a Hunter and after getting his helicopter shot down, kills several of the Mendez goons as well as finishing off Diego Mendez and Jerry Martinez on the roof. Some time after the wiping out of the Mendez Cartel, the building was demolished and replaced by a lower one before the events of Grand Theft Auto: Vice City, which occur in 1986.
