AT&T unveils massive 2-million-square-foot Plano headquarters plan

AT&T is staking its future in Plano with a 2 million-square-foot headquarters campus on a 54-acre site at 5400 Legacy Drive, a project built around a prominent blue AT&T-branded tower that would be visible across much of the city. The scale alone makes it one of the biggest corporate moves in Collin County in years, but the deeper story is what it could mean for jobs, traffic, nearby development and Plano’s standing in the Dallas-Fort Worth economy.

CEO John Stankey shared the first renderings of the campus on LinkedIn, showing a plan that would bring the company’s Dallas-Fort Worth administrative operations under one roof. AT&T said the new campus would consolidate its three largest local locations in Dallas, Plano and Irving, and that the first employees could begin working there in the second half of 2028 if the project stays on schedule. The company expects the headquarters to house thousands of workers and bring up to 10,000 jobs into the Legacy business corridor.

Plano City Council approved the incentive package on February 23, 2026, helping clear the way for the project. The city-backed deal includes a $10 million redevelopment grant, a $1,000-per-job incentive and a partial property-tax rebate on new property value for 25 years. In some coverage, the full package has been described as worth more than $36 million when grants, fee waivers and tax rebates are included.

The site carries a long corporate history. It sits on the former Electronic Data Systems campus in Plano’s Legacy district, the same area that grew out of Ross Perot’s purchase of 2,600 acres in the 1980s to create the Legacy business park. The EDS headquarters opened there in 1992, and the district later drew major employers including Frito-Lay, JCPenney, JPMorgan Chase and Toyota. That lineage is part of why city leaders have framed AT&T’s move as a major reinvestment in a corridor already tied to some of North Texas’ best-known companies.

For Plano, the project offers more than another office tower. It would deepen the city’s corporate identity, strengthen the Legacy area’s pull on restaurants, services and surrounding real estate, and push more daily commuter traffic toward Parkwood Boulevard and Legacy Drive. It also marks a symbolic shift for AT&T, which has been headquartered in Downtown Dallas since 2008, as the company moves to simplify its footprint and plant its flagship presence more firmly in Plano.
