I live in Jackson County, Illinois. I failed to check if there was an easement before buying my house, and got saddled with a 50-foot-wide ingress/egress easement. I know this is unusual, but it really isn't a utility easement. The owner apparently gave himself the easement when he sold the land to the people I bought the property from.
Can I build a duck coop on it as long as the easement owner can easily access his property to the north of my house, using the easement? His property north of mine is undeveloped land, that he mows at least once a year. He also has access from the highway next to his parcel.
