Do I have any Legal Recourse?

Based on your information, it sounds like there may have been an illegal change in use of the property and/or an unlicensed business operating on your neighbors land. So. your best bet for relief will be to involve your local or county zoning/building code enforcement department. You may also turn to your local or county department that handles business licenses to enforce their rules.

In general, such a drastic change in use of the land would need special permits-which would involve a public hearing & perhaps require a petition or consent of the surrounding neighbors. You search the zoning code for your municipality or county ordinances if you live in an unincorporated township. The code will tell you what rights your neighbor has and what restrictions apply to the use of his land.

If the local authorities do not take action, then you may have to go to court. Finally, while not a total solution, you also have rights under the Illinois Fence Act to put up a fence and have your neighbor pay part of the cost and maintenance.
