SAT14 - Phase 4 in San Antonio, TX

The SAT14 Data Center at 3545 Wiseman Boulevard in San Antonio is a new construction project completed by Microsoft. This facility features a 46,000 sq ft shell and a specific scope focused on the finish-out of one colocation unit within the existing structure. The project is now finished, having passed its final TDLR accessibility inspection in May 2026.

Microsoft, the owner of record, registered this project with the Texas Department of Licensing and Regulation (TDLR) in July 2021. The filing, identified as SAT14 - Phase 4, listed an estimated cost of $27,200,000. This valuation places the project in the top quarter of new construction filings in Bexar County, significantly above the county median of $600,000. The construction window spanned from October 2021 to the final inspection, a duration longer than the typical 208-day median build window for similar projects in the region.

Design and Construction Details

Page Southerland Page served as the design firm of record for this Microsoft facility. The firm has been involved in other high-profile projects, including the Fine Arts Building in Austin and facilities for Baylor College of Medicine. The construction was privately funded on private land, with no public funding sources indicated in the TDLR records.

Third-party data providers have noted the operational status of this site. For instance, datacenter.fyi lists the SAT14 Data Center as an operational facility with 43.1 MW of power capacity. Other sources, such as Baxtel, describe it as part of a broader network of Microsoft Azure data centers in the San Antonio area. These external reports align with the TDLR record confirming the completion of the physical construction phase.

The project's scale and cost reflect a specialized build rather than a standard commercial renovation. The $591 per square foot cost is above the county median of $115 per square foot, consistent with the high-intensity requirements of data center infrastructure. The completion of the final TDLR accessibility inspection in May 2026 marks the end of the construction and regulatory review process for this specific phase of the SAT14 campus.
