St. Louis City officials approved a conditional use permit for a data center at the former Armory warehouse in April 2026, clearing the way for a project expected to generate $27.4 million in city tax revenue in its first year. The decision comes as the city advances a broader zoning framework to regulate the wave of data center development driven by AI and cloud computing demand for electricity.
The national pressure on local zoning
Global data center revenue projections range from $300 billion to $573 billion in 2026. The U.S. holds nearly half of all operational data centers worldwide. This growth has triggered intense zoning disputes and community pushback in many markets, as developers race to site facilities and local governments scramble to write rules. St. Louis was no different.
In September 2025, Mayor Cara Spencer issued Executive Order No. 92, directing city agencies to draft a regulatory framework for data center uses. The Planning and Urban Design Agency worked with the Building Division, Office of Sustainability, Water Division, and other departments to prepare a report and zoning text amendment. The draft regulations were presented to the Planning Commission on February 11, 2026, where more than 120 people attended and over 50 commented. Residents raised concerns about electricity rates, environmental impacts, and noise, while others pointed to the potential tax revenue.
Clearing the path for The Armory
Two days after that hearing, the Board of Aldermen voted down Board Bill 172, which would have imposed a one-year moratorium on data center permits. That vote kept the door open for new applications. On April 21, city officials unanimously approved a conditional use permit for a data center at The Armory, a former warehouse familiar to residents.
The approval came with a long list of conditions addressing water use, noise, and sustainability. It also required the developer to enter into a Community Benefits Agreement, a legally binding property agreement that holds the developer accountable for specific metrics. The CBA obligates the developer to build and maintain roads and sidewalks around the site, pay liquidated damages if the project fails to meet projected tax revenue, and forego local tax abatement incentives. The development is expected to create 200 full-time jobs and deliver $33.4 million to St. Louis Public Schools in its first year.
On June 10, 2026, the Planning Commission voted to recommend approval of the broader zoning regulations to the Board of Aldermen for a final vote. The rules will face additional review before becoming final.
Why this matters for real estate and construction
The St. Louis experience shows how local governments are attaching concrete infrastructure and revenue obligations to data center approvals. For developers and contractors, that means site selection now hinges on navigating detailed zoning text amendments and negotiating community benefits agreements that dictate road work, noise limits, and water use. The data center boom is forcing a tighter link between construction delivery and long-term municipal fiscal outcomes. Professionals who understand the evolving regulatory and technical demands-including the expanding role of AI for Real Estate & Construction-will be better positioned to keep projects moving through increasingly layered local approvals.
