Bay Area Cities Tighten Data Center Rules
Coverage from KQED, The Mercury News, and others

San Jose is developing citywide standards for data centers as residents and officials weigh electricity and water use, emissions, neighborhood impacts, and public input.
Nearby cities are also changing review and notification rules or considering moratoria, while proposed standards and state legislation could shape project timelines, infrastructure costs, and local oversight.
Gilroy has moved from considering changes to adopting additional notice and review requirements, making at least one regional response concrete. The current account also introduces state legislation as a possible influence on project timelines and local oversight, without specifying its provisions.
The story has broadened from San Jose’s prospective standards to a regional policy response, with multiple Bay Area cities revising data-center review and approval rules as major projects advance.
The story now emphasizes concrete safeguards and community-benefit demands, alongside a more specific PG&E power commitment and grid-investment plan. It also introduces uncertainty over AI-related demand because developers may not disclose intended uses.
San Jose is developing uniform standards for data centers and other large-energy projects while roughly 20 facilities operate, six are under construction, and five are in entitlement review. The city’s process includes public meetings, a project-tracking website, and proposed guidelines expected to return to the City Council in December 2026. The debate is shaped by concerns about grid capacity, water and wastewater impacts, generator activity, cumulative effects in Alviso, and whether projects such as a proposed 250-megawatt Google facility should proceed before the standards are complete.
