The Jefferson Residence was home to Michael Jackson (under the fake name of Martin Jefferson) and his son Blanket. Apparently, the Donovan Family (Clyde, His Sister, and His Father) used to live in this house.
The Jefferson's house is built just like every other house in South Park. The house is colored a red-brownish color with green borders around the windows and a red roof. The Garden is full of rides and games.
The interior is heavily furnished with toys and arcade games and seems much larger than expected from the outside. On the second floor Blanket's bedroom, Michael's bedroom, a hallway and a bathroom are shown.
