Land, water and permittingSan Marcos City CouncilHaysWrite to the decider

The San Marcos City Council voted on June 16th, 2026 to define data centers in the city's zoning rules and make them ineligible for development anywhere inside the city. Council members cited concern that the facilities would draw water and energy away from the local community. The vote came after a long fight over a proposed campus and is the first ban of its kind by a Texas city. The city adopted an amended Land Development Code on the same date under ORD-2026-08, effective that day.

How to take part

The decision is made. The adopted Land Development Code, the adopted redlines and the code update summary guide are posted on the city's Code Updates page. Further amendments run through the Planning and Zoning Commission and City Council on the published 2026 meeting calendar.
