T-Mobile McAllen Data Center Ph2

T-Mobile is renovating a 14,800 square foot facility at 1400 E. Upas Ave in McAllen to house new 5G cabinets. The project, identified in filings as T-Mobile McAllen Data Center Ph2, involves the remodel of an existing telecom equipment space. The estimated cost for this renovation and alteration work is $9,500,000. The scope includes replacing the existing roof system and adding a canopy over the current loading dock. FS&L Architects is the design firm of record for this construction effort.

The work is privately funded on private land for private use. Construction was scheduled to begin in August 2025, with a planned completion date of August 2026. TDLR completed the plan review in July 2025. However, TDLR has not yet recorded a final inspection, meaning the current state of the site is not confirmed in the public record. This status indicates that while the schedule has passed, the official closure of the project file has not been documented.

This renovation represents a significant investment compared to other projects in the region. The estimated cost is above the county median for renovation and alteration filings in Hidalgo County. The scheduled build window of 365 days is longer than the county median of 92 days. Additionally, the cost per square foot is calculated at $642, which is above the county median of $71. These figures place the project in the upper tier of local construction activity for its specific type.

T-Mobile holds several other registered projects in Texas, including sites in Friendswood, Fort Worth, Katy, and Spring. In McAllen, a separate Switch Building project is also registered with TDLR. Third-party data trackers such as datacenter.fyi list this facility as under construction. The interconnection.fyi directory similarly identifies the project as a data center development in Hidalgo County. These external references align with the TDLR filing details regarding the project name and location.
