Summary

The City of Mesa's public building-inspection records for 10256 E Elliot Rd show city inspectors approving construction work on NTT's PH5 data center building in the 85 days to 7 October 2026. On its building permit PMT24-17530 ('NTT DATA CENTER PH5', Building #3, a new two-storey 225,606 sq ft data center) they recorded a water-to-building partial approval (3 August), a plumbing rough-in partial approval (11 August), an above-ceiling approval (24 August), an electric final approval (29 September) and an electrical rough-in partial approval on 7 October 2026, followed by a miscellaneous-inspection partial approval on 14 October. This records PH5 as under construction on 7 October 2026. Partial approvals cover the inspected portions only; the zoning final was cancelled on 20 October and fire-alarm and zoning preliminary inspections were rolled over on 22 October, no certificate of occupancy has been recorded, and completion, operation, IT capacity and customers are not established. The operating PH1-PH3 buildings, PH4 and the unissued PH6 are not part of this record. evidence

Use scope: Campus locator
Scope class: official_tax_parcel_centroid
Authority: Official source
Source entity: Campus
Method: official_county_assessor_parcel_centroid
Derivation: direct_geometry
Precision scope: Centroid of Maricopa County Assessor parcel 304-01-006N (situs 10256 E Elliot Rd, Mesa; owner of record NTT GLOBAL DATA CENTERS PH LLC; 101.69 geodesic acres, about 1,262 by 866 m), the parcel cited by every City of Mesa permit for the NTT Phoenix campus and the parcel that contains the city's permit geocode. It locates the NTT campus property, not the PH5 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 101.7-acre campus parcel, and the position of PH5 (Building #3) within it is not published.
Geometry evidence: 82493fac

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.
