Why Cincinnati extended its temporary data-center restrictions through 2026
Cincinnati OH – City Council extended interim data-center controls through the end of 2026 while planners write zoning rules and review live projects.
Cincinnati is keeping its temporary data-center controls in place through the end of 2026, buying more time to write permanent zoning rules for a fast-growing type of development that city planners say does not fit neatly into the current code.
WCPO reported that City Council voted April 1 to extend Interim Development Control Overlay No. 89, which had originally been adopted on an emergency basis in February and was set to expire May 11. The extension does not amount to a citywide ban. Instead, it keeps an extra review process in place for new or expanded data centers in certain zoning districts while the city studies how those projects should be regulated long term.
Why the city says it needs the extra time
According to Cincinnati’s planning department, data centers currently do not have their own definition in the zoning code. For zoning purposes, they are being treated as indoor storage. City planners say that is a poor fit for facilities that can affect energy demand, utility use, building activity, and surrounding land use in ways ordinary storage space does not.
The city says the study is meant to produce a formal definition for data centers and recommend text changes to the zoning code. Official planning materials say the concern is not just about one building or one permit. It is about whether projects with potentially high power and infrastructure demands should be allowed to move forward automatically under rules written for a different kind of use.
How broad the overlay is
This is a bigger land-use issue than the phrase “temporary restrictions” might suggest. The planning department says the overlay covers more than 22,000 parcels citywide in CC-A, CG-A, UM, DD, ML, and MG districts. That includes a mix of commercial, downtown, urban-mix, and manufacturing areas.
For residents and business owners, that matters because these are places where the city is balancing competing goals: street activity, jobs, redevelopment potential, utility capacity, and neighborhood compatibility. Officials have also said data centers can bring construction work but often support relatively low ongoing employment compared with other uses that could occupy the same land.
What the interim review means in practice
Under the temporary rules, developers seeking a new or expanded data center in the covered districts face a planning review instead of a more automatic path. WCPO reported that proposals are evaluated on factors such as neighborhood compatibility, water and utility use, adverse effects, and public benefits.
That matters most downtown and in mixed-use areas, where city officials are openly weighing whether low-activity, infrastructure-heavy facilities fit the kind of street life and building use the city wants over time. The policy is less about opposing technology than about deciding where these projects belong and under what standards.
What to watch next
The next public checkpoint is already on the calendar. The City Bulletin lists an April 17 City Planning Commission hearing on permit applications for fire suppression and fire alarms tied to an existing data center at 302 W. 3rd Street in the Central Business District.
That hearing is important because it offers a real-world look at how IDC No. 89 works while the broader zoning study continues. For downtown residents, nearby workers, and property owners, it is the clearest near-term sign that Cincinnati’s temporary data-center rules are not just a policy debate at City Hall. They are already shaping live development decisions.
