- "They ought to tear this whole place down. Nothing more than a breeding ground for tranks, lo-bos, and zipheads."

In 1985, people anticipated Hilldale to be a cool location; however by the 2010s, it had become rundown much like Lyon Estates. The sign at the entrance was graffitied over, with the wording Hilldale: The Address of Success crudely altered to Hilldale: The Address of SucKeRs.Officer Reese was of the opinion that because of the kind of people Hilldale attracted, the whole place should be demolished. (See Quote above.)
Marty McFly and his wife Jennifer Jane Parker McFly lived there with their family. When Doc Brown arrived with younger Marty there, he was excited with the idea that his future home would be there, not knowing the rundown status it would devolve into.
However, with the alterations to the timeline that followed, it is uncertain if they lived there afterward.
