San Diego Just Paused Data Center Construction — What the Unanimous Vote Means for Your Neighborhood
San Diego's City Council voted unanimously to impose a moratorium on new data center construction, including a massive proposed project near Old Town. If you own property in San Diego, here's what the pause means for housing, energy, and land use in your area.
San Diego's City Council voted 9-0 to impose a moratorium on new data center construction in the city. The vote directly affects a proposed 400-megawatt facility near Old Town — one that would rank among the largest data centers in California if built.
For homeowners and property investors across San Diego, this matters well beyond the Old Town site.
What the San Diego Data Center Moratorium Actually Does
The moratorium puts a temporary halt on permitting new data center construction within city limits while the Council evaluates the broader impacts. The vote followed intense public pressure after Manchester Financial Group proposed building a massive facility on Navy property near Old Town, known as the NAVWAR site.
Council Member Caté Campillo made the community's position clear: federal land does not exempt a project from drawing on the city's electrical grid or water supply. Council Member Sean Elo-Rivera framed it even more directly, saying San Diegans are tired of large-scale tech interests overriding local priorities, and that data centers are one area where the community can still say no.
That kind of unanimous Council language is not common. It signals a firm position, not a procedural delay.
Why Data Centers Compete Directly with Housing and Residents
A 400-megawatt data center is not a quiet office building. Facilities at that scale consume enormous amounts of electricity and water for cooling, and they generate constant mechanical noise from fans and cooling systems running around the clock. They also occupy large parcels of land.
In a city already facing a housing shortage, land used for data center infrastructure is land not available for residential development. Property owners in La Jolla and across San Diego's coastal communities already feel the pressure of limited developable land. Adding industrial-scale AI infrastructure to that competition changes the equation for future supply.
Energy demand is the other pressure point. San Diego Gas and Electric customers already pay some of the highest electricity rates in the country. A data center drawing 400 megawatts from the regional grid puts real strain on that system, and ratepayers absorb the cost of infrastructure upgrades.
What This Means For You
• Property owners near proposed data center sites should track zoning decisions closely. A moratorium is temporary, and what replaces it will shape long-term land use in those areas.
• Investors evaluating industrial or mixed-use parcels in San Diego should factor in how the city's stance on data centers affects future development potential on any site with tech-sector interest.

• The Council's unanimous vote reflects real political will, not a split decision. Expect San Diego to codify stricter data center standards through zoning ordinance before the moratorium lifts.
The san diego data center moratorium is a local response to a national trend. Cities across the country are grappling with how to absorb AI-era infrastructure without destabilizing residential neighborhoods or overwhelming utility systems. San Diego drew a line, and the 9-0 vote means that line has broad political backing. Homeowners and investors who pay attention to these decisions now will be better positioned when the moratorium ends and new rules take shape.

Frequently Asked Questions
What is the San Diego data center moratorium and how long does it last?
The San Diego City Council voted 9-0 to temporarily halt permitting of new data center construction within city limits. The moratorium gives the city time to study the energy, water, noise, and land use impacts before establishing permanent regulations.
Does the moratorium affect the NAVWAR data center proposal near Old Town?
Yes. The Manchester Financial Group proposal to build a 400-megawatt data center on the NAVWAR Navy property near Old Town was the project that brought this issue to a head. Council members made clear that even projects on federal land depend on city infrastructure and that residents deserve a voice in how that land gets used.
How could the San Diego data center moratorium affect home values near proposed sites?
Proximity to large-scale industrial infrastructure, including data centers with round-the-clock mechanical systems and high utility demand, can affect how buyers perceive nearby residential properties. The moratorium creates a window for residents to engage with the planning process before permanent land use decisions get made.
