Dispute with Private road owners
I live in Hawaii on a private road. The road is owned by 7 landowners. At the end of our dead-end private road is a turnaround area. The landowner at the end of the road rents out her house to about 3 different families and uses the turnaround area as parking for her tenants. She only has a 2 car garage. The other 6 landowners want her to stop renting out the area because we cannot use the turnaround area. Cars and emergency vehicles have to reverse all the way down the lane because they cannot turn around at the end. We have sent her a petition demanding that she stop using the area for her private rental business but she just ignores us. Can we rightfully put up No Parking/Tow Away signs? Can the Majority do that or does all 7 landowners have to agree?
