Cincinnati discovered this year that its zoning code had no word for a data center. With no definition in the code, data center applications were classified as indoor storage uses. On February 11, 2026 the City Council put an interim development control overlay over every parcel zoned for indoor storage, more than 22,000 of them in districts from downtown to Oakley, the East End and Queensgate. On April 1 it extended the overlay for nine months, to February 11, 2027. Under it, any new or expanded data center must be reviewed by the City Planning Commission for neighborhood compatibility, water and utility use, adverse effects and public benefits.

City officials have been careful to say this is not a ban. The data centers already in Cincinnati mostly serve its large employers, and Councilman Mark Jeffreys named Procter & Gamble, Kroger and Fifth Third as companies that need them. "They won't be big data farms like out in the country," he said. Planning division manager Stacy Hoffman framed the question as one of street life as much as power: "A Downtown building full of data centers where no one comes or goes isn't good for street life."

The constraint around Cincinnati is power, not water. A June study by the Ohio Chamber of Commerce Research Foundation found the Cincinnati-Dayton corridor had about 65 megawatts of available capacity against roughly 1,900 in the Columbus region, with the corridor projected to reach 450 to 550 megawatts by 2030. Duke Energy, which serves Greater Cincinnati, has asked state regulators for a distribution increase it puts at about $8 a month for households; the Ohio Consumers' Counsel says it could reach $18.

At least 138 Ohio municipalities and townships had active data center moratoriums as of September 17, and 23 had effectively banned them, the Ohio Capital Journal counted. Next door, Butler County passed a six-month moratorium covering six of its 13 townships, and the city of Hamilton paused a proposal after finding it would take about 30 months to deliver 45 megawatts. The city's planning department is holding public meetings on the zoning study on October 1 and October 19.
