⏸️ Pause on new data centers · McHenry County
The county is weighing a 12-month freeze on data center applications, zoning changes and building permits in unincorporated areas. A county committee was set to review it in early October 2026; a board vote could come in November. The county relies only on groundwater for drinking water and has no data center rules yet.
