On October 20, 2026, the Hayward City Council voted unanimously to hit pause on new data centers. The council adopted an urgency ordinance imposing a 45 day moratorium, which took effect immediately. During the pause, the city cannot approve new data center proposals. Developers can still submit applications, but no approvals will move forward until the city decides what comes next.That decision is not the end of the story. Under state law, the council can extend the moratorium, first by 10 months and 15 days, then by another year, for up to two years in total. A hearing to extend it is tentatively set for December 1, 2026. If the council votes to extend, the pause could run until October 2027, with the option to extend again until October 2028. Hayward is not banning data centers outright. It is buying time to write permanent rules.Why the pause? The city is studying the cumulative impact of data centers on energy and water supplies, air quality, industrial noise, emergency response capacity, and the city's economic development priorities. The vote followed months of community pressure, including an August 11 community meeting with Mayor Mark Salinas, after the city approved the 310,000 square foot STACK data center in May 2025. Hayward already has four data centers clustered near PG&E's Eastern Substation in its western industrial district: a 24 megawatt facility and a 35 megawatt facility on Corporate Avenue, a 49 megawatt facility on Clawiter Road, and the 76.6 megawatt STACK project under construction on Eden Landing Road. A developer has also approached the city about two more, 99 megawatts each, near Arden Road and Corporate Avenue.What the moratorium covers, and what it does not: it covers new data center proposals. It does not shut down existing facilities, and it does not stop the STACK project already under construction, because that project was approved before the pause. The two proposed 99 megawatt centers near Arden Road and Corporate Avenue are the projects most directly affected. Their timelines are now uncertain until the council decides on the extension and the city finishes its study.What it means for nearby properties: for industrial land in western Hayward, especially near Arden Road, Corporate Avenue, Clawiter Road, and Eden Landing Road, development timelines just got longer and less certain. That uncertainty cuts both ways. A pause can slow land deals and entitlements, and it can also make approved or existing industrial space more valuable while new supply is frozen. For homes near the industrial district, the questions are different: noise, truck traffic, and what gets built next door. The moratorium does not change what is already approved, so nearby owners should look at what is under construction today, not just what might be proposed tomorrow.Your checklist before you buy, sell, or invest near the pause:1. Check the entitlement status with the City of Hayward's Development Services records. Is the project approved, under construction, or only proposed? Under the urgency ordinance the council adopted on October 20, 2026 (Council item LB 26-015), the pause applies to new data center proposals, so confirm the project's status with the City of Hayward.2. Confirm whether the moratorium applies to the specific parcel. Projects already approved or under construction are generally not covered by the pause, but confirm the status of any specific parcel with the City of Hayward or a licensed professional.3. Review infrastructure: power capacity, water supply, and any conditions attached to the approval.4. Check the timeline: the December 1 extension hearing, then the city's study and the permanent rules that follow.5. For nearby homes, ask about noise, traffic, and future land use in the area.6. Talk with the city and a qualified professional before assuming a timeline or a value. The rules are being written right now.Hayward is writing the rules for its industrial future in real time, and the next few months will shape what gets built near Eden Landing Road and the western industrial district for years. If you own, invest, or are looking at property in Hayward, this is worth watching closely. Questions about buying or investing in Hayward?
