Yeah I would find out this stuff before you buy. Sometimes old stuff is grandfathered in but then you're not allowed to touch it. Cities now days are getting more and more nazi about what you can do on your own property. I look at all my neighbours they have sheds in the back on slabs. I was not allowed to do that, because of easement. Only legal spot was right in the middle of the yard. I built it on 6x6s so that I can move it in the future with jacks and a rail system as I'll eventually put it in the illegal spot where it belongs once we get a council that is not as nazi. Or I might get so used to having it there that I'll end up leaving it.
