San Francisco has paused new data centers. The city's Board of Supervisors voted unanimously on Tuesday for a 45-day moratorium that took effect immediately, in the city that is home to OpenAI and Anthropic.[1][3] The measure can be extended to 22 months, and its author hopes it ends in a permanent ban.[2]
It is a small city measure with a big symbolic punch. The AI boom is built on buildings full of computers, and here is the boom's own hometown telling developers to wait. We have written before about how chips are one choke point in the CoWoS packaging bottleneck. This story shows that finding somewhere to plug those chips in is becoming a choke point too.
What the vote actually does
The ordinance freezes city approvals of new data centers and expansions of existing ones for 45 days.[1][4] Facilities that already run can keep operating, but nobody gets to build or grow while the pause lasts.[9] District 10 Supervisor Shamann Walton wrote it, with support from Supervisors Connie Chan, Jackie Fielder and Chyanne Chen.[1]
During the pause the Planning Department will study energy, water, air quality, land use and community impacts, and work on stronger rules and a clear definition of what counts as a data center.[1] City leaders are due to hold a hearing on its findings by November.[1] If the study finds a significant environmental impact, the moratorium can be extended up to 22 months or replaced with permanent controls.[2] The San Francisco Standard notes it is unclear whether leaders would entertain the full 22 months.[1]
Which projects are caught
The pause stops the expansion of NOVVA, a 7.6-acre data center at 400 Paul Avenue in the Bayview area.[2] It also halts a proposed 49.5 megawatt project in Dogpatch, according to The Next Web's summary.[3] That is a meaningful amount of power for a city this dense, and it explains why neighbours have been paying close attention.
There is a fairness argument at the heart of the vote. SFist reports that District 10 has historically carried a disproportionate share of the city's industrial pollution, and that existing data centers are concentrated there.[4] Walton has said he wants to understand all the impacts before another facility goes in, and the vote followed a long public comment session where dozens of residents backed the measure.[4][6]
It is not just San Francisco
Oakland approved a similar 45-day moratorium the same week, and Richmond did so in September.[5] A coalition quoted by Oaklandside says at least 26 California cities are considering or have passed something similar.[5] Southern California's Monterey Park went further, moving from an interim pause to a permanent ban in May.[6] KTVU reports that cities across the Bay Area and Southern California are stepping back to review long-standing policies as concerns about energy demand and water use rise.[7]
Europe offers a cautionary tale. The Next Web notes that several European pauses were driven by grid limits, and that the continent now struggles to build the capacity the European Commission wants.[3] The lesson is that a pause can look prudent early and costly later, depending on how quickly the rules catch up.
The case for and against
Supporters say communities deserve to know the water, power and pollution costs before agreeing to more. They also point out that the city says it cannot even confirm how many data centers it already has, which makes planning hard.[3] At the Oakland meeting, speakers argued that people should have oversight of technology that affects energy, water and land.[5]
Opponents and sceptics make a different case. One Oakland resident told the council that data centers bring jobs, not job losses.[5] Developers can also simply build elsewhere, which may move the same load, and the same pollution, to a place with weaker protections. Both views are reasonable. The honest test is whether the Planning Department's study produces specific, workable rules or just a longer delay.
Why this matters beyond California
For AI companies, the lesson is about location risk. Compute capacity needs land, power and permission, and local politics can now veto the last of those. The economics already look tough, as our breakdown of Anthropic's reported losses shows. Adding permitting delays on top does not help.
For everyone else, it is a preview of how the AI build-out will be argued over: one council meeting at a time. The same arguments about electricity bills and water are showing up in other places, and the outcome will shape where the next wave of computing is built.
What we still do not know
Quite a bit. The city cannot say how many data centers it already has, so the baseline for the study is shaky.[3] It is unclear whether the full 22 months will ever be used, and the Planning Department has not published findings yet.[1] A reader comment on Mission Local even asks whether the board's make-up could change after the election and reverse the measure. That is speculation, not reporting, but it shows how fragile temporary rules can be.[2]
What this means for you
If you live in San Francisco or Oakland, watch for the November hearing and use public comment, since that is where these rules get shaped. If you build or invest in AI infrastructure, add local permitting to your risk list and look closely at sites that already have approvals. If you simply use AI products, expect more of these debates in your own area. None of this is investment advice.

Common Questions
What did San Francisco decide about data centers?
On October 6, 2026 the Board of Supervisors voted unanimously for a 45-day interim moratorium on new data centers and expansions of existing ones. It took effect immediately. The measure can be extended up to 22 months while the Planning Department studies energy, water, air quality, land use and community impacts.
Which projects does the moratorium affect?
Reports name the planned expansion of the NOVVA data center at 400 Paul Avenue in the Bayview area and a proposed 49.5 megawatt project in Dogpatch. Facilities that already operate keep running.
Is this a permanent ban?
No. It is a temporary measure. Sources close to its author, Supervisor Shamann Walton, say he hopes it leads to a permanent ban, but the outcome depends on the study and on future votes. A hearing on the findings is due by November.
Are other cities doing the same thing?
Yes. Oakland approved its own 45-day moratorium the same week and Richmond acted in September. A coalition cited by Oaklandside says at least 26 California cities are considering or have passed similar measures, and Monterey Park moved to a permanent ban in May.
Why do cities worry about data centers?
Data centers use large amounts of electricity and water, produce noise and take up land. Local officials say they want to understand the community and environmental effects before approving more, particularly in neighbourhoods that already carry a heavy pollution burden.
