An earlier thread, The Case Against Zero Lot Line Zoning, brought up a number of issues and problems such properties can have, mostly involving encroachment by a neighbor, spillover effects of a neighbor's activities/problems (pests, flammable debris, flooding), and access to your wall. That got me wondering about solutions. Being an interested outsider and not a professional planner, I figure some of you would have tackled these issues and know far more than I ever will about them.

So, oh Throbbing BrainTM, my question is: What solutions have you guys (and gals) come across or implemented? Particularly what worked? How did it work?

(I asked this in the other thread, but it might be different enough in content to justify its own thread. So, here it is, my first new thread--I think)
