Austin data center permits, Q3 2026: four sites filed to add capacity, all outside the City of Austin, and the Governor ordered a halt to state environmental permits for data centers.

The small hollow grey dots are data centers operating today, from the public PeeringDB facility list, each linked to its PeeringDB record. An operating building is context for the filings and is in no count on this page.

TABS numbers are state registrations, never issued, and the others are City of Austin permits and plan reviews. Values are the filers' own estimates, never added together.

A pending registration at Earl Callahan Road, Cedar Creek, is under Reported.

• Skybox Old Settlers, Round Rock. Rezoned in February 2026 under a plan asking to allow a data center, with no permit in Round Rock's reports through August (Round Rock council). A planning case with no filing date on record.
• Prominent Property Group, Jarrell. A 150.92-acre tract annexed and zoned light industrial in October 2025 and given a preliminary plat in February 2026, which the press ties to a 200 MW data center (October minutes, February minutes, DCD, KXAN). The city's records do not name a data center.

Cielo Digital's proposed data center in the city's Caldwell County part, discussed in closed session in September 2025, and two more projects with data centers at August 2026 workshops (minutes, 4 August, 17 August).

• Tesla Cortex 2.0, Giga Texas, Travis County. An AI training cluster Tesla calls online, with county fire permits for data halls 6 to 9, an extension filed in the quarter and a 46,400 square foot building registered with the state on 25 August (Tesla update, data halls, extension, registration). No Q3 record states a power figure or what the new building houses.

Boundary. The Austin-Round Rock-San Marcos metropolitan area as the Bureau of Labor Statistics defines it: Bastrop, Caldwell, Hays, Travis and Williamson counties.

What is counted. Only work that adds data center buildings or capacity: new buildings, a change of use to a data center and, at a data center already on file, work stating added power with a figure. A new building or site naming a data center counts without a stated capacity, and power work not naming one counts only above 1 MW. Replacements, repairs, renovations, offices, renewals and amendments do not count. Planning cases in Taylor, Round Rock, Hutto and Jarrell are described but not counted, since their council records give no filing date.

Counting. A site is one address or one campus and counts once in a quarter however many jobs it files. Burr's four FM 535 buildings this quarter are one site, at two addresses that county appraisal records put in one campus, as Community Impact reported, and Uppingham's two at 6543 are another. A project is dated by its first application or registration. No counted record states megawatts.
