Permits are the brake on the AI data center buildout. Here's what North Carolina's permit records show.

Ask what's slowing the AI buildout and the answer is increasingly permits. Dell'Oro Group, which tracks data center infrastructure spending, said on October 14 that it now regards siting and permitting as "the most serious near-term brake on the market," and that the timing of permits and grid connections is harder to forecast than the demand behind them. In North Carolina that brake shows up in two places: the local and state approvals that decide whether a data center can be built at all, and the building permits that mark the ones actually going up.

Where the permitting constraint actually sits

"Permitting" covers several different approvals, granted by different people, and the building permit comes last. The slow, uncertain steps come before it.

• Zoning and local pauses. A data center needs land zoned for it, and local boards are slowing new approvals. Charlotte City Council voted unanimously on June 8, 2026, for a 150-day moratorium on new data centers, running to November 5; it does not affect data centers already approved. Chatham County paused permitting for new data centers in its unincorporated areas for 12 months in February 2026, and Gates County passed the state's first one-year moratorium in December 2025.
• State environmental permits. Backup power needs air permits. In August 2026 the NC Division of Air Quality issued two for Amazon's Richmond County data center: one for 588 backup generators and one for 57 Duke Energy diesel generators to power construction for a year. The state's environment secretary said the division's "statutory authority is limited in the review of these projects."
• Power. A campus can't open without a grid connection, and those queues set many project schedules.
• Building permits. The last gate, issued by the county or city once plans pass review. When a shell or upfit permit is issued, the project is real, the general contractor is named, and trade packages are being bought.

For anyone who builds, supplies or finances these projects, that last step matters most. A rezoning or an announcement says a data center might be built. The permits say it is being built, by whom, and roughly when each trade starts.

What the permit record shows in west Charlotte

Charlotte City Council rezoned 156 acres on Moores Chapel Road, between I-85 and Wilkinson Boulevard, for Digital Realty in May 2025. Five months later, local news reported that trees had been cleared but that it was "unknown when formal construction will commence." Mecklenburg County's permit records answer that. The first permits were issued on March 4, 2026. A shell permit for a 1,294,518-square-foot building followed on May 29, and the same day a $150.3 million upfit permit labeled "CLT 13 PBB". Between July 6 and September 4, eight more upfit permits were issued, each declared at $39.8 million to $42.0 million; the ones with a description call themselves new data hall suites.

Around those sit the trade permits: two dozen electrical permits covering switchgear, generators, UPS systems and medium-voltage feeders from the substation, plus 11 plumbing, 10 mechanical and 6 fire permits. The owners of record are Digital Moores Chapel LLC entities with a Dallas address. Brasfield & Gorrie is the contractor on nearly every permit, with Aldridge Electric on electrical work and Hoopaugh Grading on site work. All eight of those upfit permits were issued during Charlotte's moratorium, which doesn't reach projects already approved.

Every data center job in the permit records, since January 2025

Outside Charlotte, most of the work is power and cooling inside existing buildings, which is what higher-density AI racks demand. At CyrusOne's Durham site, one permit covers chilled-water piping, coolant distribution units and liquid-cooling racks for a data hall, and another a new 1.5-megawatt electrical lineup. NetApp's and Fidelity's permits in Research Triangle Park are UPS, generator and distribution packages. Duke University's is a new single-story building for GPUs. For electrical, mechanical and fire-protection contractors these retrofits are often the more reachable work: smaller, more frequent, and bid one package at a time.

How long the last gate takes

Where an office records both the application date and the issue date, the data center permits above took from one to four and a half months. NetApp's $8.5 million UPS and generator permit was issued 66 days after it was filed in Wake County. Fidelity's $7.4 million UPS permit took 56 days, and a smaller interior permit at the same building took 112. In Raleigh, American Tower's modular addition took 133 days and its power-module building 34. Mecklenburg County and Durham don't publish application dates in the records TarSignal reads, so the Charlotte and Durham jobs can't be timed the same way.

Big permits take longer because they go through full plan review, often in several rounds. Part of each wait is the applicant's: an office's clock usually keeps running while plans go back for corrections. Morrisville and Greensboro had only seven such permits each, so treat their numbers as rough. For smaller permits, see our office-by-office permit timelines.

Where TarSignal fits

TarSignal can't shorten a council vote, an air permit review or a grid queue. What it does is show, every day, which projects have cleared the last gate in the North Carolina offices it reads, and who's building them.

• Subcontractors and suppliers: look up a campus address in Permit Search to see every permit filed there, with the general contractor and trade contractors named on each, then search by contractor (Brasfield & Gorrie, DPR, Whiting-Turner) to find their other North Carolina jobs.
• Project Alerts (Pro): a daily email of new permits in the counties, towns and trades you choose, with a minimum project value, so the next $40 million data-hall upfit or generator package reaches you the morning after we read it.
• Planning a schedule: Permit Search shows the application and issue dates on each permit where the office records them, so you can check how long similar permits took in that office before promising a start date.
• Analysts, utilities and investors: the Data & API plan delivers the same permit records by API or bulk export, for tracking the buildout county by county instead of waiting for announcements.

What's in these numbers

• Data center permits are those whose description names a data center or data hall, plus every permit at the campuses in the table, issued or applied for from January 1, 2025, to October 18, 2026, in the permit offices TarSignal reads. Withdrawn permits, an unrelated event permit at the Duke address, and permits that describe themselves only as a server room are left out.
• Declared cost is the construction value the applicant put on the permit. It isn't the project's full cost: land, equipment that isn't part of the building, and work on permits without a value aren't counted. At the Charlotte campus, the $488.7 million is the building and upfit permits; the trade permits there declare about $5.7 million more.
• Counties that aren't in TarSignal's coverage, including Richmond and Person, aren't in these counts. The approvals news cited above (moratoriums, air permits, rezonings) comes from the sources listed below, not from permit records.
