Denver bans new data center construction for one year while city studies permanent regulations

The council acted in response to sustained community pressure, particularly from residents of north Denver neighborhoods Globeville, Elyria, and Swansea near an existing CoreSite facility. Dozens of Denver residents testified at the public hearing, citing constant noise, diesel generator air pollution, and water use as harms. The moratorium gives the council time to convene a working group — including community advocates, utility representatives, union members, industry representatives, and subject-matter experts — to recommend permanent regulations covering zoning, energy use, cooling systems, and renewable energy requirements. Councilwoman Serena Gonzales-Gutierrez, one of the sponsors, noted Denver currently hosts 50 data centers, roughly half of whose square footage sits in council district 10.

For AI infrastructure builders, the Denver moratorium is an early test of what community-level regulatory backlash looks like in practice. Data centers are the physical substrate of AI workloads: training runs, inference infrastructure, and cloud AI services all depend on the facilities now blocked from new construction in Denver. The ordinance does not affect existing centers or expansions of currently-under-construction facilities, but any planned greenfield AI compute build in Denver is on hold. The working group's recommendations — due before the one-year moratorium expires — could produce permanent zoning, noise, water, or renewable energy requirements that set a template for other US cities where community opposition to AI infrastructure has grown.
