The data center fight in Jefferson County, Iowa
As of October 1, 2026, Jefferson County, Iowa has a data center moratorium in force (action taken Aug 11, 2026; documented end date 2027-08-11).
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
12-month moratorium adopted unanimously alongside a new data center ordinance; second and third readings waived so it took effect at once. County attorney recommended 1 year over the 24 months residents asked for, as more likely to survive a legal challenge

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.
