I am in PA. We own a building that when purchased was beside a metered public parking lot. The lot has since sold and the new owner wants to place a fence that will block access to our handicap ramp. I can not place the ramp anywhere else unless I make it steeper which would be against code. Can they do this since the ramp was already present or is there anyway they have to give us room to access the ramp. The fence will be right on the edge of their property so are we screwed? Thank you in advance.
