- Source Briefing
- Public record
A four-story, 372,443 sq ft data center projected at $500 million was registered Nov. 11, 2026 for 1520 West Mockingbird Lane in Dallas. The filing is a Texas Department of Licensing and Regulation accessibility registration, and it names an owner entity but no operating company.
Why it matters
Data center construction is a major line of new spending in Dallas-Fort Worth, and state accessibility registrations often surface a project months before a permit or public announcement. This one is inside the city of Dallas, in ZIP code 75235, rather than in an outer suburb.

The registrant is DA12 LLC, with a Redwood City, California address, and the project is listed as DA13-1 at the facility named DA13. The record names no tenant (“Not Assigned”) and no operating brand, so this story does not attach one. The design firm is Margulies Hoelzli Architecture of New York.
The numbers
- Estimated cost: $500,000,000, per the TABS registration TABS2027005620.

What’s next
The next public steps are a City of Dallas building permit and any utility filings for the site. A permit would show a valuation to compare with the $500 million registration estimate, and a tenant or operator may surface there. Electric load requests tied to the address would show the power the campus needs. More Dallas projects are tracked on the Dallas market page.
