The building was the hideout for the Los Santos Vagos gang until it was torched in the mission "Burning Desire". It is also where CJ saved Denise Robinson from the fire, after he threw Molotov Cocktails inside the house.
The house is a blue building, with two tan chimneys, tan window shutters, black shingles, and a red door.
•The red door after the mission, is still there. You can take a car, and crash on the door. The door will be destroyed. However, after that, the door will no longer be there.
