Rules and source checks.

The county review below is separate from site-specific conditions and municipal or township zoning. It does not establish parcel permission or current compliance.

Cook County

Code version limited · Checked October 17, 2026.

The county guidance describes zoning administration in unincorporated Cook County and identified forest-preserve matters. A linked 318-page amendment document is explicitly labeled proposed; it is not treated as an enacted current code.

No data-center-specific rule was established in these checked sources. The guidance and linked proposed document do not supply a complete current-code audit. Chicago, Elk Grove Village and other municipal ordinances are separate; the proposed document cannot prove no applicable law exists.

The dated record.

The retained event log distinguishes announcements, scheduled dates and status-source checks. A review date is not an opening day. A target never becomes a completed event merely because time passes.
