The data center fight in Chicago, Illinois
As of October 1, 2026, Chicago, Illinois has a data center moratorium under consideration.
Status is derived, not stored — a pause with a documented end date flips to Expired on its own — and the source is right next to the claim.
Status today
Mayor Brandon Johnson signed Executive Order 2026-5 on Aug 11, 2026, directing city departments to strengthen data center oversight and calling on City Council to enact a temporary moratorium. Executive order imposes enhanced air pollution, noise, and planned development review requirements immediately. City Council must approve the moratorium for it to take effect. 90-day rulemaking clock set for Dept of Environment.

An expiry date is the earliest a pause could have ended — extensions are common, so confirm with the clerk before citing it.

As of August 2026 (2m ago) · changes weekly — re-check before citing
Illustrative rather than exhaustive — dozens of localities churn weekly, and this tracks the ones we have read a source for. **Each row carries its own provenance.** Rows showing a verification date link to the ordinance, the enacting body's own page, or a datable report of the vote, and were read on that date. Rows marked *unverified* came from bulk compilation and have not been checked against a primary source — the locality, the year, and the status may all be off. Verify one of those with the town clerk before citing it as precedent. **Expiry is derived, not asserted.** A row with a documented end date flips to *Expired* on its own once that date passes. A time-limited moratorium whose start date was never documented keeps showing as enacted — that is a known gap, not a claim that it is still in force. Moratoriums are also routinely extended, so an expiry date is the earliest it could have ended, not proof that it did.
