Mayor Daniel Lurie Signs 45-Day Data Center Moratorium Approved 11-0 by Board of Supervisors to Study AI Power Demands

Mayor Daniel Lurie Signs Emergency 45-Day Moratorium on Data Center Construction

SAN FRANCISCO, California — Taking swift executive action to address the massive technological transformation reshaping Northern California, San Francisco Mayor Daniel Lurie officially signed an emergency ordinance in mid-October 2026 imposing a 45-day municipal moratorium on new commercial data center developments and major server facility expansions. The landmark legislation was sponsored by District 10 Supervisor Shamann Walton and achieved unanimous 11–0 approval by the San Francisco Board of Supervisors, with Board President Rafael Mandelman expediting committee consideration.

The temporary freeze directs the San Francisco Planning Department, the San Francisco Public Utilities Commission (SFPUC), and regional electrical grid operators to conduct an intensive technical audit assessing the cumulative strain that artificial intelligence server farms place on municipal power substations, potable water supplies, and neighborhood noise baselines.

Board of Supervisors Evaluates AI Infrastructure and Renewable Grid Resilience

During City Hall deliberations, supervisors emphasized that while San Francisco continues to serve as the global capital of artificial intelligence research and venture capital, physical hardware hosting facilities must not cannibalize precious urban space or jeopardize the city's statutory clean energy commitments under CleanPowerSF. The ordinance strictly exempts routine maintenance, municipal hardware upgrades, and accessory enterprise server closets smaller than 10,000 square feet.

The resulting planning study will establish permanent zoning guidelines, including mandatory recycled-water cooling standards and dedicated municipal grid-modernization developer fees, before any large-scale industrial data center permits can be issued in districts like the Bayview, Showplace Square, or SoMa.

Lurie Administration Balances Tech Economic Growth with Neighborhood Livability

Speaking at City Hall, Mayor Lurie affirmed that sensible regulatory pauses protect working neighborhoods and prevent commercial displacement while fostering a predictable, sustainable business climate. Business coalitions and environmental advocates alike commended the prompt, unanimous collaboration between executive and legislative leaders, ensuring that San Francisco’s infrastructure expands responsibly alongside technological innovation.
