Legal Question in Business Law in Illinois

Re: Prohibited from entering a building.

If I understand your question, then yes, they can prevent you from entering a building that they rent. Whether I rent my office building or own it, I have the right to refuse entry to people. Just because I have a business, does not mean I am required to allow anyone in my building. Renting makes no difference. You run your business from your house, but people can't come in there and use the head and check the weather without your permission, correct? Same for any business. Maybe if you offer to pay a little bit? After all, you're making money, and they are effectively subsidizing your business and saving you the expense of having your own office somewhere. Think of it from their perspective. They pay to rent the building, they pay for cleaning the restrooms, they pay for the water you use, they pay for the paper towels, they pay for the computer connection so you can check the weather, they paid for the computer you use, they pay for the electricity, etc. You come in there, essentially running your business from their establishment, and they get no compensation from you. I have to say I would do the same.
