Thayer County
Anti-Data Center Policies
Thayer County allows data centers only with a conditional use permit in FLEX and I-1 districts; applicants must show utilities can serve them and pay for infrastructure extensions, and meet operating standards.
current law · Unincorporated areasRegulates data centers to promote responsible development, compatibility with surrounding land uses, environmental protection, and public health and safety.Thayer County Zoning Regulations § 9.22 — Data Centers (2025)
What this means
Data centers are allowed only by conditional use permit in the FLEX and I-1 districts, so projects face review and are barred in other listed districts (the use matrix). Applicants must show that utilities can serve the facility and pay to extend infrastructure (all costs to extend infrastructure); noise, buffering, water use, and other operating standards add requirements, but the rules do not ban development.
