Around here all yards are fenced in- good fences make good neighbors! The fence goes on the property line of course-
who would give 2-3 feet of their yard all around to the neighbors?? Also you never need to go "maintain" the other side of the fence- that is the other persons job- my neighbor next door put up a wood fence- he liked his side stained and that is what he did with his side- the guy on the other side wanted it painted to match his house and that is what he did with his side- each person weed whacks their own side (I do get a kick out of people calling it weed eating though LOL).
For those of you that think the fence should be 3 feet in on your own property- then your neighbor puts theirs 3 feet in on their property and you have a 6 foot gap of nothing in between?? Yuk. And if you didn't put up a fence but your neighbor did then when he was on "your" side of hte fence it would be like he was in the yard with you- what if your dog was running around your yard and bit the person???
