Warren City Council passed a one-year moratorium on large-scale data centers on September 9, 2026. The ordinance covers data centers larger than 1,000 square feet, meaning it is not limited only to hyperscale facilities. The council simultaneously established a Data Center Review Committee, which is directed to study the issue and report back to the council within nine months — leaving three months before the moratorium expires for the council to act on the committee's recommendations. The moratorium was sponsored by council members Greg Greathouse and Greg Thumm. Warren is the county seat of Trumbull County in northeast Ohio. The measure is part of a broader cluster of Ohio localities acting on data centers in 2026, including Franklin County Commission and multiple communities pursuing ballot initiatives in November 2026.

Legal detail
City of Warren, Ohio (Trumbull County) — one-year moratorium on large-scale data centers enacted by City Council on September 9, 2026, expiring September 9, 2027. SIZE THRESHOLD: the moratorium covers data centers larger than 1,000 SQUARE FEET. This threshold is deliberately written to capture facilities smaller than hyperscale campuses; a 1,000 sq ft floor catches mid-size colocation and edge computing facilities. REVIEW COMMITTEE: the ordinance establishes a DATA CENTER REVIEW COMMITTEE charged with studying impacts and reporting to the council within NINE MONTHS — timed to give the council three months before expiration to enact or extend. SPONSORS: council members Greg Greathouse and Greg Thumm. OHIO CONTEXT: Warren is the county seat of Trumbull County. In the same period Franklin County, Kansas enacted a similar county moratorium; in Ohio, eighteen communities pursued November 2026 ballot measures on data centers and the state legislature has several data center bills pending. WARREN IS DISTINCT FROM: franklin-county-oh-jackson-twp-dc-mora-2026 and franklin-county-oh-pleasant-twp-dc-mora-2026 (both Ohio but different county); oh-warren-county-dc-moratorium if one were indexed (Warren City is in Trumbull County, not Warren County).
