Oakley's City Council voted 3-1 on Tuesday to introduce an ordinance that would ban data centers in every zoning district in the city — including setups small enough to run out of someone's house. Vice Mayor Aaron Meadows cast the lone dissenting vote on a measure that, if adopted, would make Oakley one of a growing number of California cities moving to shut the door on the industry before it ever knocks.
The ordinance targets commercial data centers as well as anyone trying to operate a similar facility as a home-based business, according to East Bay Times. The paper reports that the rule would only stop a homeowner or resident from getting a business license and home business permit to run the operation — personal-use equipment inside a residence would not be restricted. Oakley's municipal code currently does not regulate or define data center land uses at all, the outlet notes, leaving the city with essentially no framework for handling the technology until now.
Councilmember Shannon Shaw said the council had heard about companies paying individuals to set up small data centers inside their homes, per the same report. Even so, Shaw acknowledged nothing like that has actually surfaced in Oakley. While there haven't been similar instances in the city, she said officials wanted to “get ahead of it.” It remains unclear whether home-based data centers of this kind have ever been installed at scale anywhere, the outlet reports.
A Moratorium That's Been Building for Months
A Moratorium That's Been Building for Months Tuesday's vote didn't come out of nowhere. Oakley became the first Bay Area city to impose a temporary data-center ban back in April 2026, starting with an initial 45-day hold before extending the pause by 10 months and 15 days, pushing the moratorium out to April 14, 2027, according to Contra Costa News. That moratorium blocks the city from accepting, processing or approving any land-use applications tied to data centers, giving officials time to rework zoning rules and tighten regulation before any project could break ground.
By midsummer, Oakley leaders were already signaling a permanent ban might be coming. City officials said in July that roughly 141 municipalities nationwide had enacted permanent or temporary bans of their own, according to The Mercury News. The ordinance introduced Tuesday would, if ultimately adopted, override that moratorium once it takes effect and prohibit data centers of any size or name within city limits — a far more sweeping and permanent approach than the stopgap measure Oakley has relied on for the past several months.
What Happens Next
The timeline from here is straightforward but not yet finished. Bay Area News Group's Danielle Navarro reported that the council is expected to adopt the ordinance in December, and that it would go into effect 30 days after adoption. Once in effect, the ordinance would override the moratorium currently governing the city's handling of data-center applications — but Tuesday's action was only an introduction, and the council has not yet taken a final adoption vote.
Oakley isn't alone in moving this way. Monterey Park enacted a permanent ban through a ballot-measure initiative. The Coachella staff report recommended that Coachella consider its own temporary 45-day moratorium on accepting or approving data-center development applications, pointing to a California statute that lets cities adopt urgency interim ordinances to block land uses that might conflict with planned zoning changes.
Why Tiny Home Nodes Are Even Part of the Conversation
The home-based language in Oakley's ordinance isn't being written in a vacuum. Span announced in April 2026 that it was in early testing with chipmaker Nvidia to install small fractional data-center “nodes” on the outer walls of newly built homes, East Bay Times reported. CNBC reported in May that Span's XFRA units — small, fractional data centers that can be mounted on the side of residential homes and small commercial buildings — had been deployed in a single home at the time of its report. Span says a network of these nodes, communicating across the country, could function like a small- to mid-sized traditional data center. Span did not immediately respond to a comment request from Bay Area News Group, according to East Bay Times.
The scale of the industry's bigger players helps explain why some cities are nervous. The Abilene, Texas, campus being built for OpenAI and Oracle is designed for 1.2 gigawatts of capacity, which at full power around the clock would equal roughly 880 gigawatt-hours a month — about the electricity consumption of one million homes, per East Bay Times. For comparison, the average U.S. home uses about 900 kilowatt-hours of electricity monthly, according to the Energy Information Administration. A Coachella staff report has cited projections suggesting data centers could account for up to 12% of U.S. electricity consumption by 2028, while a Lawrence Berkeley National Laboratory report put a 2030 estimate range at 521 to 843 terawatt-hours of U.S. data-center electricity consumption.
For now, Oakley's ban remains introduced but not adopted, with the council's next move — a final vote expected in December — set to determine whether the moratorium gives way to a permanent, citywide prohibition.
