Summary
Round Rock has no by-right zoning category for data centers; siting requires a case-by-case Planned Unit Development rezoning approved by City Council, as seen in the 250,000-square-foot Skybox PUD.
Only one data center building may be constructed. It is limited to 250,000 square feet in floor area, 60 feet in height, and 75 megawatts of grid-interconnected power. The proposed data center must use a closed-loop cooling system, which is written into the planned unit development (PUD) as a binding requirement.
Full Breakdown
Round Rock's base zoning code does not list "data center" as a permitted or conditional use, so operators must rezone through a Planned Unit Development that City Council negotiates project-by-project. The precedent-setting Skybox Old Settlers PUD (PUD25-00009) converted 29.69 acres from Light Industrial to PUD, capping the site at one data center building, 250,000 square feet, 60 feet in height, and 75 megawatts of grid-interconnected power, while mandating closed-loop cooling and limiting on-site generators to emergency, testing, and utility-managed load-shedding use. City Council gave final approval February 12, 2026, after months of public hearings.
Violations & Fines
Building without an approved PUD rezoning, or exceeding the negotiated caps on floor area, height, or power draw, or running generators outside the permitted emergency/testing/load-shedding uses violates the binding PUD conditions the city enforces.
