Google Mesa Building 2

Google Mesa Building 2 is the second building on Google's Redhawk campus in Mesa. City of Mesa records show a certificate of occupancy issued on September 29, 2026 on the permit for the campus's Phase 2 above-ground buildings and structures.

Proposed data center in 3164 S Sossaman Rd, Mesa. Operated by Google.

Where it stands

Permit PMT24-16556, which the City of Mesa issued on December 10, 2024 for the Phase 2 above-ground buildings and structures, shows the status C of O Issued, finaled on September 29, 2026. The Phase 2 foundation permit, PMT24-07723, and the permit for an electrical substation to power the Red Hawk Phase 2 Red building both show the status C of C Issued, finaled on September 10 and September 29, 2026. Cleanview, a listing site, listed the building as planned and expected to become operational in 2026.

The short version

Is it finished?

  • The City of Mesa issued permit PMT24-16556 on December 10, 2024 for the above-ground buildings and structures of Phase 2, which excludes pre-engineered metal buildings, and the permit shows a certificate of occupancy issued on September 29, 2026.
  • A city permit to install an electrical substation "to power Red Hawk Phase 2 Red building" shows a certificate of completion the same day.
  • The city's permits do not say which numbered building is which, and a certificate of occupancy does not show computer equipment in service.
  • Epoch AI, which estimates data center capacity from satellite imagery and a cooling equipment model, estimates that Building 2 became operational on August 15, 2026, based on near-complete construction seen in May 2026.
  • AZBEX reported in October 2025 that Mesa permitting showed Phase II construction began as of early March. Cleanview still lists the building as planned and expected to become operational in 2026.

How big is it?

  • The design plan in April 2024 was for a 280,000-square-foot building, and Cleanview lists it at 138 MW.

What did Mesa approve for the campus?

  • The City of Mesa announced that the City Council approved the development agreement with Google on July 1, 2019, and said the milestone minimums in it do not reflect the actual project scope.
  • The city's council report describes a first milestone, tied to the water allowance, of at least 250,000 square feet of buildings and $600 million of capital investment before July 1, 2025, and an annual water allowance of 1,120 acre-feet that rises by 1,120 acre-feet with each of three milestones, up to 4,480 acre-feet.

How is the campus cooled and powered?

  • Google said in December 2023 that its planning study found the local water source at high risk of depletion and scarcity, so it chose to air-cool the Mesa data center.
  • SRP's witness said at a November 2019 hearing that SRP could serve in the neighborhood of 500 megawatts to the site, for a customer described as an affiliate of Google.

How we know this

Compiled from public records and checked on 2026-11-13. Confidence in this record: high. Blank figures mean the number is not publicly established, not that it is zero.

Each statement on this page is listed with the page it came from and the words that say it. Sources open in a new tab.

Our own notes

These remarks are Arizona AI's own. They say how this record is counted or what we could not find, so there is no outside page to link.

The city's permits name phases, not buildings. Phase 2 is taken to be this building, the second on the campus, but no city record states that.
