The 34-year-old recently purchased a house in Silver Lake, LA and a group of residents there have now written an open letter complaint to the actor, reported Hollywood Life.
In the note, the neighbours allege Franco does not live at the property and that their grievances over production vehicles blocking their driveways have been ignored by a female employee of the actor, named Iris.
"At first we were pleased to have Mr Franco living next door. His work in 'Milk' and his academic pursuits made us happy he was on our street. That is no longer the case. If, in fact, Mr Franco has purchased the house next door, it does not appear to be inhabited by the actor; it does appear to be inhabited by several people who are working for him.
