More than 530 US counties and municipalities now restrict or block new data centers

The AI data center backlash stopped being protests and started being law. More than 530 US counties and municipalities now restrict or block new data centers.

What the records show

Heatmap Pro’s review of public records puts the total above 530, and the pace is accelerating: nearly 190 of those measures were passed since June 1, 2026 alone. New York’s one-year statewide moratorium on new data center approvals is not even counted in that figure, since it is a state action rather than a local one.

The restrictions are translating into dead projects. More than 50 data center projects were cancelled in 2026 after local pushback, more than twice the cancellations in all of 2025. About half of contested projects now die, up from roughly 40 percent historically.

The state-by-state spread is wide. In Michigan, 71 percent of challenged proposals were cancelled. In Indiana, 56 percent. In Texas, 17 percent.

What the objections are actually about

The striking part is the content of the complaints. Local opposition is not organized around AI ethics or job displacement. It is organized around power bills, water use and noise, the same categories that have blocked landfills and highway extensions for decades. The AI buildout is being slowed by the most local politics there is: zoning boards, county commissions and town meetings.

That matters because local land-use politics is durable in a way national AI debates are not. A moratorium passed over utility rates does not depend on how anyone feels about the technology itself.

The counterweight

The numbers cut both ways. More than 90 percent of US counties still have no restrictions at all, which leaves developers plenty of map to work with. The question the Heatmap data raises is whether the restricted 530 are concentrated in exactly the places with the grid capacity, water and fiber that hyperscale projects need. If contested projects keep dying at a 50 percent rate, siting strategy, not chip supply, becomes one of the binding constraints on the buildout.
