San Francisco board approves pause on new data centers

San Francisco board approves pause on new data centers

Rule Changes San Francisco, CA local

45-day moratorium awaits mayor's signature; could extend to 22 months

Yesterday: Board unanimously approves 45-day moratorium

Overview

Updated 1 hour ago

San Francisco's Board of Supervisors voted unanimously Tuesday to stop approving new data centers for 45 days. The moratorium, which awaits Mayor Daniel Lurie's signature, could stretch to 22 months while the Planning Department studies how AI infrastructure affects energy, water, and air quality.

The vote puts San Francisco in the middle of a regional wave. Gilroy, Richmond, and Oakley already have moratoriums; Oakland and Los Angeles County are weighing their own. The city's zoning rules for data centers date to 2001, before the AI boom changed what these facilities require.

Why it matters

The moratorium could delay new AI data centers in San Francisco, forcing companies to build elsewhere and setting a precedent for cities weighing similar pauses.

Scenarios

1

Mayor signs data center moratorium into law

Likely Resolves by Oct 20, 2026

Discussed by: The San Francisco Standard, city political observers

Mayor Daniel Lurie signs the 45-day moratorium, triggering the pause on new data center approvals and starting the Planning Department's study. The board could then vote to extend it to 22 months while long-term rules are developed.

2

Moratorium extended to 22 months after planning study

Possible Resolves by Dec 15, 2026

Discussed by: The San Francisco Standard, Planning Department

After the initial 45-day period, the board votes to extend the moratorium to 22 months while the Planning Department develops long-term data center zoning rules. This would give the city time to craft new standards for energy, water, and community impacts.

3

Moratorium expires after 45 days without long-term rules

Possible Resolves by Dec 15, 2026

Discussed by: Data center industry observers

The moratorium runs its 45-day course without extension. The Planning Department's study continues, but new data center applications resume under the existing 2001 zoning rules. The article notes it's unclear whether city leaders would entertain an extension.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2001

San Francisco's 2001 data center zoning rules

San Francisco designed its zoning framework for data centers in 2001, when computing infrastructure was far less resource-intensive. The rules don't account for the energy, water, and environmental demands of modern AI data centers.

Then

The rules governed data center development for 25 years.

Now

The framework is now seen as outdated for AI-era infrastructure.

Why this matters now

Walton cited the 2001 rules as the reason for the moratorium: 'We should not be approving this new generation of industrial infrastructure under rules that were written 25 years ago.'

September 2026

California's September 2026 data center moratorium wave

Gilroy (Sept 14), Richmond (Sept 15), and Oakley enacted moratoriums on new data center approvals. Oakland and Los Angeles County followed with their own pauses.

Then

A regional pause on data center development across the Bay Area and beyond.

Now

Cities are developing long-term zoning rules for AI infrastructure.

Why this matters now

San Francisco's moratorium is part of this coordinated regional response to the rapid growth of AI data centers.
