St. Louis moves toward new zoning rules for data centers, with limits on location and impacts

St. Louis begins formal push for data center zoning standards

St. Louis officials are moving to establish zoning rules specifically for data centers, a land use that has not previously had dedicated standards in the city’s zoning framework. A newly released preliminary regulatory framework sets out proposed definitions, where different types of data centers could be located, and operating conditions intended to address noise, emissions, energy use, and water demand.

The initiative follows an executive order issued on Sept. 19, 2025, which created interim expectations for developers while city staff prepared a longer-term approach. City officials have described the framework as a work in progress and have scheduled it for public discussion as part of the Planning Commission’s Feb. 11, 2026 meeting.

What the draft framework would change

The proposed framework is structured around a core goal: create a predictable review process with minimum standards, while distinguishing between smaller facilities and larger, higher-impact projects. Under the approach outlined publicly by city officials, larger data centers would be steered toward industrial zoning districts and separated from “sensitive uses,” with project conditions designed to reduce operational impacts.

• Data centers would be regulated by size categories so that large facilities face different requirements than smaller sites.
• Larger data centers would be restricted to industrial areas, paired with separation standards from sensitive uses.
• Operational controls would aim to limit and mitigate noise and emissions.
• Design expectations would encourage energy and water efficiency, and seek to preserve walkability in areas such as Downtown.
• Review procedures would be designed to maximize transparency and preserve opportunities for community input.

How the framework could become law

The proposal would not take effect automatically. Any new zoning standards would require approval by the Board of Aldermen and the mayor’s signature. If adopted, the rules would replace the interim approach established under the 2025 executive order.

The framework is described by city officials as a preliminary set of recommendations that will be refined through public feedback, stakeholder discussions, and review by city boards and commissions.

What happens next

The Planning Commission’s Feb. 11, 2026 meeting is set up to include a public hearing component, with participation available both in person and online. City officials have also indicated that written comments can be submitted in advance.

For residents and businesses, the next steps will clarify whether St. Louis sets citywide rules that define where data centers can go, how they must operate, and how projects are reviewed—especially as demand for large-scale computing facilities grows and local governments seek clearer land-use tools.
