Hayward City Council Pauses Approval of New Data Centers to Study Water, Energy and Noise Impacts

HAYWARD, Calif. — The Hayward City Council voted unanimously on October 20, 2026, to impose an immediate moratorium on considering and approving new data centers, according to an official city announcement published October 21.

What the city is examining

The council is asking staff to examine cumulative effects of existing and proposed data centers on electricity demand, water supplies, air quality, industrial noise, emergency-response capacity and economic development. The city says the pause is intended to allow more analysis and potential changes to zoning rules.

Hayward’s official announcement identifies multiple existing or approved data centers near Pacific Gas and Electric’s Eastern Substation in the southwestern industrial area. Some operate today, while another has been under construction. The moratorium addresses new approvals; it should not be characterized as an order shutting down existing sites.

How long could the pause last?

The city says state law permits such a moratorium to remain in place for up to two years while officials consider land-use changes. That is a maximum potential period, not confirmation that the pause will last exactly two years.

Questions for residents and businesses include whether utility costs and infrastructure improvements would be fairly shared, how facilities would be monitored and what emergency capacity is required. Future council agendas and staff reports are the best place to track changes or extensions.
