Compass Datacenters Files $300M in Red Oak Tenant Fit-Outs

Compass Datacenters registered $300 million in tenant fit-out construction across three buildings at its Red Oak data center campus, according to three Texas Department of Licensing and Regulation filings submitted the same day, Oct. 15, 2026.

Why it matters

Each of the three TDLR TABS filings lists a $100 million estimated cost on its own. Read together, they describe one operator registering 755,445 square feet of interior fit-out across three buildings on one Ellis County campus on a single day, a concentrated commitment to Red Oak rather than a single-building bet.

The numbers

The three registrations cover Buildings 8, 9 and 10 of the DFWIII-III project, each at $100 million and 251,815 square feet of interior tenant fit-out for a new data center on an existing data center campus, per the filings:

• TABS2027003683, Building 8, 580 Austin Blvd., owner Compass Datacenters DFW IIIJ LLC, estimated completion Oct. 28, 2027.
• TABS2027003693, Building 9, 550 Austin Blvd., owner Compass Datacenters DFW IIIH LLC, estimated completion March 14, 2028.
• TABS2027003697, Building 10, 590 Austin Blvd., owner Compass Datacenters DFW III-I LLC, estimated completion Aug. 22, 2028.

All three list HED as the design firm and no general contractor on the public record. No tenant is named on the filings; Building 10’s registration reads “Tenant not assigned.”

What’s next

The filings put completion between Oct. 28, 2027, and Aug. 22, 2028, building by building. Under Senate Bill 6, loads of 75 megawatts or more face ERCOT large-load interconnection review, so the campus’s place in the state’s power queue may matter as much as the construction schedule for when these buildings can energize. Ellis County permitting and tax records tied to the DFWIII-III project are the next records to check as the buildings near completion.
