Does my Illinois county have to approve a data center on my land?
Unlike much of the country, Illinois counties zone rural land and a project of this kind usually needs a public approval. That is a slower path and it is also the strongest protection an Illinois landowner has.

Short answer: usually yes. Illinois counties zone rural land, so a large facility on agricultural ground in an unincorporated county ordinarily needs a discretionary approval, commonly a special use permit, decided in public. That is slower than in a non zoning state and it is also the strongest protection an Illinois landowner has.
If you have read about landowners in Texas or Oklahoma being approached about this, some of what you read does not apply to you, and the difference is worth understanding before you take advice written for somewhere else.
Illinois gives counties that power directly. Under 55 ILCS 5/5-12001 a county board may regulate the location and use of land outside the limits of any city or village, and nearly every rural Illinois county has taken that up. So a large facility on agricultural ground in an unincorporated Illinois county will ordinarily need some form of discretionary approval, commonly a special use permit, decided in public by people who can be voted out.
The statute is enabling rather than mandatory, so the one thing worth checking rather than assuming is whether your own county has a zoning ordinance and what it calls this kind of use. Your county clerk can tell you in a phone call.
That changes almost everything about how this arrives at your door.
What does having a public process mean for me?
Three things, and the first two are good for you.
You get information. A proposal that has to be described to a zoning board has to be described accurately, in public, with drawings. What is being built, how big, where, how it gets power and water, what the traffic is during construction. That is a great deal more than a landowner in a non-zoning state ever sees before committing.
You get conditions. An approval can come with terms attached, on hours, lighting, noise, screening, setbacks, road repair, water, decommissioning. Those conditions are enforced by somebody other than you, which is a meaningfully different thing from a promise in a contract you would have to sue on.
And you get uncertainty. The same process that protects you can refuse. A petition can be denied, or approved with conditions that make the project uneconomic, or dragged out past the point where a buyer’s own timeline survives.
Why am I being offered an option instead of a sale?
This is the piece that confuses people, and it makes more sense once the zoning process is in view.
Nobody is going to buy your farm outright and then find out whether the county will allow anything on it. The approval has to come first, and getting it takes months and costs money. So what gets put in front of an Illinois landowner is usually an option: a period during which the other party investigates, applies, and tries to get approval, with payments to you for that period and a price agreed now for a purchase that may never happen.
That structure is not a trick. It is the shape the county process forces. It does mean you can spend two years committed to something that ends with a no, which is why what the option pays, and what you can and cannot do with your ground during it, matter as much as the eventual price.
Will I have to stand up at the hearing?
Worth preparing for rather than being surprised by.
A zoning hearing on a project like this is public and your neighbours will be there. In many counties you as the landowner are the applicant or a co-applicant, which means the petition is in your name even though somebody else wrote it.
Decide early how you want that handled. Whether the buyer’s people present and you sit quietly, or whether you speak. Whether your neighbours hear it from you first or from a notice in the paper. Whether you are comfortable being publicly associated with it, because in a small county you will be, for a long time.
None of that is a reason not to proceed. It is a reason to have thought about it before a date is set.
How do I find out what my county is likely to do?
Many Illinois counties have adopted ordinances aimed at large energy and industrial uses, and some have set setbacks, siting standards or moratoriums. Others have not touched the subject.
Your county’s zoning ordinance and the minutes of the last year of board meetings will tell you more about your realistic prospects than any conversation with a buyer will. Both are public and most counties put them online.
If your county has recently refused something similar, that is worth knowing before you sign an option that ties your ground up for two years while somebody finds out the same thing.
What should I ask before signing an option?
What approval does this actually need in my county, and have you read our ordinance.
Have you applied anywhere in Illinois before, and what happened.
Am I the applicant, and if so what does that require of me.
What happens to my option payments if the county says no.
What am I allowed to do with the ground during the option period, and who pays if the crop is disrupted.
Where we sit in this
We buy and option land for our own account with our own capital. Nobody here earns a percentage, we do not represent sellers, and your property is not shopped to a list of other parties.
In Illinois we read the county ordinance before we read anything else, because a property in a county that will not permit this is not a candidate however good the ground and the power are. When that is the answer, it is a short conversation and you will get the reason.
The county, roughly the acreage, and the name on your electric bill is enough to start.
