Chicago Mayor Brandon Johnson is pushing for a one-year pause on new data center development as the city considers how to regulate the rapidly growing industry.
Johnson and several City Council members introduced an ordinance on Sept. 23 that would impose a citywide, one-year moratorium on new or expanded data center permits and approvals. The proposal has been referred to the City Council for consideration.
The move comes as officials examine how data centers could affect Chicago’s electricity, water supply, zoning rules and quality of life.
Chicago weighs data center moratorium
The proposed moratorium would give city officials time to develop a broader regulatory framework for data centers.
Chicago already has 39 active data centers, according to city officials. The facilities can require significant amounts of electricity and water, particularly as demand for artificial intelligence infrastructure continues to grow.
Johnson has argued that Chicago needs updated rules before allowing additional development.
The mayor previously called for a temporary moratorium in August and directed city officials to work on stronger regulations.
AI growth puts data centers in focus
Data centers have become increasingly important to the growth of artificial intelligence.
However, their expansion has also sparked debates over electricity demand, water consumption and environmental impacts.
Chicago officials are considering rules that could address those concerns while also determining how new facilities should fit into neighborhoods.
The proposed pause would give the city additional time to study those issues before approving more projects.
City Council faces competing proposals
Johnson’s proposal is not the only plan under consideration.
Ald. Bill Conway has proposed separate regulations that would introduce additional zoning and community review requirements for data centers. His approach would regulate the industry rather than relying on a yearlong moratorium.
The competing proposals could shape how Chicago handles future data center projects.
Meanwhile, the mayor’s one-year moratorium ordinance remains under consideration by the City Council.
Chicago joins national data center debate
Chicago is part of a broader national discussion about how communities should manage data center growth.
Other U.S. cities have also considered temporary restrictions or new regulations as officials examine the facilities’ effects on local resources.
The debate has intensified alongside the rapid expansion of AI infrastructure.
For Chicago, the next step will depend on City Council action on the proposed moratorium and other data center regulations.
