The DiLaurentis home is where Alison and Jason DiLaurentis lived with their parents before Alison went missing. Alison's body was unearthed in the backyard of their house, where the gazebo was being built, a year after her death. Alison's "death" prompts the DiLaurentises to move away from Rosewood, and Maya St. Germain and her family moves into the house. Jason eventually buys back the house and begins renovating it himself. In Season 4, Jessica DiLaurentis moves back into the house alone, without Jason after separating from her husband.
The Hastings' residence is right next door to the DiLaurentis home which makes them neighbors. There have been conflicts between Spencer and Jason's parents over property lines in the past. Spencer's bedroom is visible from Ali's bedroom and vice versa.
Season 4 reveals Alison is still alive, after being pulled from the gazebo by Carla Grunwald, meaning that someone else was killed and buried in the backyard (which was later revealed to be Bethany Young).

The St. Germains come across the body when undergoing outdoor construction of their own. Maya finds it difficult to feel at home after the discovery, but she and her family stay put. However, after Maya is sent away to reform school for her drug usage, the St. Germains leave Rosewood.

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.
Jason buys the house back with his endowment money. Spencer goes over one night to bring Jason brownies to welcome him back to the neighborhood; in some ways, she really goes to find out information, but Jason is cold to her.

At that moment, Spencer recalls how Alison used to take Jason's belongings and expertly hide them around their home. Alison's penchant for hoarding things is confirmed when Jason reports to Aria that Alison had hidden a box of old things under her floor boards, including a roll of film containing undeveloped pictures of Aria. Jason develops that film later in the makeshift dark room he has set up in his shed.

That night Spencer looks out her window and sees Jason wallpapering the windows with newspaper; he later hires Toby to help him with construction in the yard, though it is unclear what the overall construction goal is.
