If your neighbor and you have a common fence face-interchanging sides separated by a 4 inch wood between the sides is it legal to put a 3 inch high net over your fence on this 4 inch wood?

Answer 1

Depends on who owns the fence, i.e. whose property it is on or who bought it in the first place. Often one person installs a fence (maybe 3 owners ago) then allows the neighbor to install wood on their side of the owners fence. This wood is the owners wood but people do it cause it is cheaper than installing a second fence on their own property. If you own the fence (its on your property) then you can do whatever you want including tear it down. If it is on their property they can tell you what you can or can't do. The best thing is to go to the neighbor and actually talk with them about what you'd like to do.
