How we know this

Compiled from public records and checked on 2026-10-11. 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. Arizona AI takes Phase 3 to be this building, the third on the campus, but no city record states that.
