530 US Counties Now Restrict New Data Centers

The count: 530 counties, and climbing fast

More than 530 US counties and municipalities now have some form of restriction on new data centers, according to a review of public zoning and planning records published by Heatmap News. The restrictions range from outright bans to noise limits and setback rules that are, in practice, impossible for a hyperscale facility to meet. The pace is what stands out: roughly 190 of those restrictions, more than a third of the total, have been enacted since June 1, 2026 alone.

The caveat matters as much as the count. Heatmap's review also found that more than 90 percent of US counties still have no restriction on data centers at all. This is a fast-growing phenomenon concentrated in specific hotspots, not yet a majority-of-America trend, and both facts are true at once: the restriction map is spreading quickly, and most of the country remains open for new construction.

What 'restricted' actually means on the ground

Few of the 530-plus jurisdictions have passed a law that says 'no data centers' in so many words. Most restrictions are procedural: a noise ordinance capped at a decibel level a substation and chiller plant cannot meet, a setback rule that makes the available parcels too small, a moratorium pending a study that keeps getting extended. Heatmap's review found these forms far more common than outright bans, which makes the restriction map harder to see coming - a project can clear every headline hurdle and still be quietly unbuildable on the specific parcel a developer has under contract.

The Information's corroborating reporting counted more than 300 bans and moratoriums nationally, a smaller number than Heatmap's total because it excludes the noise and setback rules that function as bans without naming themselves as one. Newsweek's mapping of the same trend shows the restrictions clustering in fast-growing exurban counties, exactly the geography hyperscalers have favored for cheap land and available power.

Cancellations are running at double last year's pace

More than 50 data-center projects have been canceled or blocked in the US so far in 2026, more than double the total for all of 2025. The cancellation rate on contested projects has climbed with it: historically, roughly 40 percent of challenged data-center proposals were canceled over a five-year span, and Heatmap found that rate has risen to about 50 percent in recent months. The pace varies sharply by state, which is itself the point - Michigan and Indiana have seen cancellation rates well above the national figure, while Texas has stayed in the teens.

Public opinion has moved with the projects. Heatmap cites polling showing support for local data centers has swung by roughly 49 percentage points against them over nine months, and a majority of Americans now say they would back a moratorium at the local, state, or national level. A local board that approved a facility eighteen months ago is voting in a different political climate today.

A signed capacity deal is not a zoning approval

This is the part that gets lost in corporate announcements. A power-purchase agreement, a signed lease, or a hyperscaler's public capacity roadmap describes an intention and a contract - it does not describe a zoning approval, and it does not survive contact with a county planning board that has just adopted a noise ordinance nobody can meet. The gap between 'we have committed to build here' and 'we are permitted to build here' is exactly where the 530-county map lives.

This is not a new risk in kind - land use has always been decided locally in the United States - but it is new in pace. A jurisdiction that was open to a data center a year ago may not be today, and 190 new restrictions since June is evidence the window can close faster than a procurement cycle.

What to ask before you sign

Anyone evaluating a vendor's cloud GPU availability, a colocation contract, or a hyperscaler's stated capacity roadmap should ask a more specific question than the corporate announcement answers: what is the local entitlement and zoning status of the physical site behind this capacity, right now, not at the time the deal was announced. That means the underlying parcel, the jurisdiction's current ordinance, and whether a moratorium or noise-limit challenge is pending - not just the press release.

None of this argues for blanket pessimism about US data-center capacity. More than 90 percent of counties remain open, and the industry is still building at scale in the jurisdictions that want it. The right response is site-specific due diligence on every capacity commitment a business is relying on, applied consistently, not a retreat from the sector.
