B Dup's Apartment is the home of Mark "B Dup" Wayne located in Ganton, Los Santos. It was B Dup's former residence before he moved to his new home in Balla territory after the Grove Street Families were disbanded in the mission The Green Sabre. The apartment interior is seen during the mission Cleaning the Hood and the hallway is seeing in both Cleaning the Hood and Beat Down on B Dup. The apartment is not normally accessible but can be accessed through the use of cheats or modifications.
The apartment itself is rather small, as Carl Johnson is almost as tall as the ceiling. Random things from clothes to Burger Shot items are seen on the floor. There are posters everywhere and a little bed, the kitchen is also rather small. Outside the apartment graffiti is seen like OG X-Ballas SV and GSF.
- During the mission Cleaning the Hood B Dup instructed Big Bear to clean his toilet. B Dup doesn't have a toilet and it is unknown where he uses the bathroom.
- The crackhead during the mission Beat Down on B Dup is the same crackhead seen in The Introduction.
- The VHS player under B Dup's TV is manufactured by Sony, as the texture reveals.
