- "Home of wannabe gangsta rapper, Jefferey Martin. No criminal record. Some unpaid parking fines. Unlikely to be a threat. Do not, repeat do not listen to his music."

OG Loc's House is the home of OG Loc, former member of Grove Street Families and rapper, and is located in Grove Street, Ganton, Los Santos. It is inaccessible to the player and is only seen during the mission House Party. Although from the outside the house appears to be two-story, when the hidden interior is accessed through trainer packs, it is revealed that the house is actually a single-story. The texture of the walls on the inside of the house are neon and rainbow coloured to simulate the effects of the party lights during the mission House Party. The house can be accessed through the Hidden Interiors Universe.
After OG Loc rose to fame, it is not said if he continued to reside on Grove Street, or moved to a wealthy neighborhood.
