Wylie, TX Data Centers & Crypto Mining: Data Center Zoning & Siting (2026)

Appendix B, Section 5.1's Land Use Chart lists Data Center with an S, meaning Special Use Permit required, in the Commercial Corridor (CC) district, and a P*, permitted by right subject to additional standards, in the Light Industrial (LI) and Heavy Industrial (HI) districts, with parking set Per Approved SUP rather than a fixed ratio. No other district on the chart, including any residential district or the Neighborhood Service, Community Retail or Business Government commercial districts, carries an entry for the use. Section 5.2.H.8.b layers on additional, size-triggered requirements that apply on top of the district-level table: a Special Use Permit is required within the Commercial Corridor district regardless of size, and separately, a Special Use Permit is required for any data center whose cumulative building area reaches or exceeds 5,000 square feet per platted lot, even in LI or HI where the base use is otherwise permitted by right.

Any development over that 5,000-square-foot threshold must also submit a utility study showing compatibility with existing city and franchise infrastructure. For a facility with an approved Special Use Permit, two further conditions apply: the developer must provide a will-service letter from the water provider, and the development must be built on a closed water loop system rather than drawing on the open municipal supply for cooling or process water. Together, the size trigger and the water conditions mean that even a by-right LI or HI site becomes an SUP-and-utility-study project once it crosses the 5,000-square-foot line.
