Alison's House

The DiLaurentis home is where Alison and Jason  lived with their parents before Alison died. Alison's body was unearthed in the backyard of their house a year after her death. Alison's death prompts the DiLaurentises to move away from Rosewood, and the St. Germain family move into the home instead. Jason eventually buys back the house and begins rennovating it himself.

Season 1
Maya is creeped out by the Alison memorial paraphenalia that crops up all around the house as she is moving in. After Maya is sent away to reform school for her drug usage, the St. Germains leave Rosewood.

It is revealed in flashbacks that Jason used to throw wild parties in the house when their parents were gone and in general used to smoke pot in his room with his friends. After Spencer finds the photograph of Alison on her computer that was taken from the perspective of Jason's house, she shows it to Jason, who confesses that he may have taken the picture the night Ali disappeared. He agrees that it could have been taken from the vantage point of his room, but as he was probably stoned that night, he doesn't recall taking the picture.

Season 2
Jason buys the house back with his endowment money. Spencer goes over one night to bring Jason cookies to welcome him back to the neighborhood; in some ways, she really goes to find out information, but Jason is cold to her. A few days later, Spencer sees a figure walking inside Jason's home, so she asks him who is living with him, but he answers that he is in the house alone... That night Spencer looks out her window and sees Jason wallpapering the windows with newspaper; he later Toby to help him with construction in the yard, though it is unclear what the overall construction goal is. Mike tries to break into Jason's house one night when the lights are off, but Jason opens the door and catches Mike in the act.
