Joliet Residents for Responsible Growth v. City of Joliet (Joliet Technology Center Data Center Zoning Suit)
A nonprofit group, Joliet Residents for Responsible Growth, sued the City of Joliet and developers Powerhouse and Hillwood over the city's March 19, 2026 annexation and rezoning approval of the roughly $20 billion, 795-acre Joliet Technology Center data center campus, alleging defective public notice and Open Meetings Act violations. Will County Circuit Judge Victoria Breslan heard argument on the city's and developers' motions to dismiss on September 8, 2026; no ruling had been reported as of this entry.
Why it matters
The suit is a procedural, rather than substantive, challenge to a major data center approval -- targeting public notice and open-meetings compliance instead of the underlying zoning judgment -- and is emerging as part of a national pattern of similar procedural challenges to hyperscale data center approvals, alongside comparable disputes in Edgerton, Kansas and Westlake, Texas. Developers and municipalities should treat notice and hearing procedure as a first-order legal risk for large rezoning and annexation approvals.
