Summary

EdgeConneX PHX11 — 412,065 sq ft core-and-shell data center building with Data Hall 1-4 build-outs, under construction (Mesa permits PMT24-11896, PMT25-09255 and PMT25-17623)

The City of Mesa's public building-inspection records show the EdgeConneX PHX11 building still under construction in September 2026. Its core-and-shell permit PMT24-11896 ('EDGECONNEX PHX11', a 412,065 sq ft building with two shell data hall wings, offices, storage and back-up power infrastructure, issued 16 September 2024) and its Data Hall 1-2 build-out (PMT25-09255) both had certificate-of-occupancy inspections that returned corrections on 8 September 2026, and on the Data Hall 3-4 build-out (PMT25-17623, the south pair of data halls: interior walls, MEP systems, generators, switchgear, chillers and CRACs) inspectors recorded mechanical rough-in partial approvals on 17 and 26 August and 9 September and above-ceiling partial approvals on 7 August and 23 September 2026. Data Hall 1-2 had above-ceiling and electrical rough-in partial approvals and a fire-overhead approval in August 2026. This records the PHX11 building and its data-hall build-outs as under construction on 23 September 2026, the latest named construction inspection. Partial approvals cover the inspected portions only; no certificate of occupancy has been approved for the shell or any data hall, and completion, operation, IT capacity and customers are not established. The PHX12 building is a separate project on the campus. evidence

EdgeConneX PHX12 — 296,800 sq ft core-and-shell data center building under construction (Mesa permit PMT25-22027)

The City of Mesa's public building-inspection records show city inspectors approving foundation and underground work on EdgeConneX's PHX12 building in the 85 days to 20 October 2026. On its civil-and-shell permit PMT25-22027 (a new 296,800 sq ft precast core-and-shell building on the campus parcel, whose tenant build-out is filed as 'EDCPHX12 - Tenant Buildout') they recorded a plumbing-underground partial approval (4 August), seven footing partial approvals (13 August to 10 September), a water-to-building approval (20 August) and five electric-underground approvals or partial approvals between 23 September and 20 October 2026, the latest on 20 October 2026. This records the PHX12 building as under construction on 20 October 2026. Partial approvals cover the inspected portions only; the building's interior build-out permit (PMT26-08118) is not yet issued, no certificate has been recorded, and completion, operation, IT capacity and customers are not established. The adjacent PHX11 building and its data-hall build-outs are not part of this record. evidence

Derivation: direct_geometry
Precision scope: Centroid of Maricopa County Assessor parcel 304-03-011X (situs 3261 S Hawes Rd, Mesa; owner of record LOOP 202 & ELLIOT ROAD LLC; 93.13 geodesic acres, about 792 by 489 m), the single current parcel that contains the city permit geocodes of both EdgeConneX buildings (PHX11 and PHX12). It locates the EdgeConneX Mesa campus property, not the PHX12 building footprint, a surveyed boundary or the works extent.
Horizontal uncertainty: Not reported
The assessor publishes no positional accuracy for parcel polygons; the centroid represents a 93-acre campus parcel, and the PHX12 building's position is indicated only by the city's permit geocode, 153 m from the centroid.
Geometry evidence: 36ad5920

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
