# San Francisco supervisors unanimously pass a 45-day moratorium on new data centers and expansions, extendable to 22 months

On Oct 6, 2026 San Francisco's Board of Supervisors unanimously approved an immediate 45-day moratorium on approvals of new data centers and expansions of existing ones, extendable up to 22 months, while the Planning Department studies energy, water, air-quality, land-use and community impacts. Oakland, Los Angeles County and Santa Clara were weighing their own pauses or reviews.

## Key facts
- Vote: unanimous, Oct 6, 2026; effective immediately; 45 days, extendable to up to 22 months (KTVU, Mission Local)
- Author: District 10 Supervisor Shamann Walton; co-sponsors Connie Chan, Jackie Fielder and Cheyenne Chen
- Projects affected (Mission Local): NOVVA's planned expansion at 400 Paul Ave, Bayview, from 9 MW to 36 MW by 2028; a proposed 160,000 sq ft facility at 1215 Michigan St, Dogpatch (permits filed, no construction)
- Walton: the pause lets the city 'study energy, water, air quality, land use, and community effects'
- Other California cities (KTVU): Oakland weighing its own 45-day moratorium; LA County received a proposal to ban hyperscale data centers; Santa Clara (56 data centers) starting a year-long review

## What happened

The city that hosts OpenAI, Anthropic and many other AI labs voted to pause new data centers while it studies their local effects.
The measure was proposed in mid-September amid concern about AI-driven demand, and passed unanimously on Oct 6. The facilities
directly affected are small by hyperscale standards (NOVVA's Bayview site would grow from 9 to 36 MW), so the vote matters more as a
signal than for compute capacity.

## Why it matters

It adds San Francisco to a growing list of local pauses (Seattle in June, New York State in July) and comes as several other
California governments (Oakland, LA County, Santa Clara) consider similar steps. Local permitting is becoming a real constraint on
AI infrastructure near cities.
