The Bay Area Data Center Boom: What Homebuyers Should Know

LOCAL EXPERT SUMMARY: The rapid expansion of artificial intelligence and cloud computing has triggered a data center boom across Santa Clara County and the broader Bay Area. As communities from South San Jose to Gilroy navigate zoning changes and infrastructure demands, it is critical for local homebuyers to understand how these massive commercial projects might shape neighborhood development and long-term property values.

Key Takeaways for San Jose Readers:

Land Use Matters: Future development around a home-such as the transition of open spaces or historic campuses into data hubs-is just as important as the property itself.
Zoning is Evolving: Cities like Gilroy and Hayward are actively revising or pausing data center applications to update their regulations.
Due Diligence is Essential: Buyers must review city planning documents and infrastructure plans rather than making assumptions about how commercial proximity affects home values.

When most Bay Area buyers think about the forces shaping our housing market, they probably think about mortgage rates, inventory, commute times, new housing, and the strength of the local job market. But as technology evolves, there’s another development worth paying attention to: data centers. As artificial intelligence, cloud computing, and digital services continue to expand, companies need enormous amounts of computing infrastructure to support them. That means finding land for facilities filled with servers, along with access to the electricity, water, and fiber required to operate them. In my 20+ years representing Bay Area buyers and sellers, I have seen Silicon Valley landscapes transform dramatically. From Gilroy and Hayward to South San Francisco, communities are deciding where data centers belong and how they should be regulated. You don’t need to become an expert in server infrastructure, but if you’re considering buying near one of these proposed or developing sites in Santa Clara County, it is well worth understanding what is happening in our backyard.

Why Are So Many Data Centers Being Built in the Bay Area?

Data centers provide the physical infrastructure behind modern digital services, meaning the demand for facilities capable of supporting them has skyrocketed alongside AI and cloud computing. The Bay Area is a natural location for this growth because of its heavy concentration of technology companies and existing digital infrastructure. However, building here comes with distinct challenges, particularly when it comes to finding suitable land and securing enough electrical capacity. That combination is creating some fascinating real estate and land-use proposals throughout the region that directly intersect with residential neighborhoods.

Silicon Valley’s Evolving Footprint: The search for suitable land is pushing developments outward from traditional industrial zones into areas like South Santa Clara County, making proximity to infrastructure a new conversation for suburban buyers.
Long-Term Financial Planning: As neighborhoods evolve, understanding tax implications remains crucial. Before buying a home near an evolving commercial corridor, review how tax assessments reset in our guide to Santa Clara County Proposition 13 property taxes.

Almaden Valley: What Could Happen to IBM’s Historic Campus?

One project particularly worth watching for South San Jose buyers is the future of IBM’s longtime Almaden Research Center at 650 Harry Road. The expansive campus has been part of the Almaden landscape for decades. As IBM shifts operations away from the property, questions have naturally emerged about what could eventually happen to the site. Portions of the property have industrial zoning, while much of the surrounding acreage consists of open space and habitat.

Look Beyond the House: If you’re considering a home near the Harry Road corridor, this is a prime example of why future land use matters. What exists today may not necessarily be what exists ten years from now.
Verify with the City: Always check active planning documents. For properties located within city limits, you can verify current zoning codes and active development applications through the City of San Jose Planning and Building Department.

Gilroy and Hayward: Cities Pause and Pivot on Data Centers

Gilroy has become one of the Bay Area’s most closely watched examples of the data center debate. An Amazon data center currently under construction in northeast Gilroy prompted significant community discussion about how these projects are approved. On September 14, 2026, the Gilroy City Council unanimously approved a temporary citywide moratorium on new data center development to give the city time to establish specific zoning, siting, and operating standards. Meanwhile, in the East Bay, the Hayward City Council has similarly considered proposals to prohibit new data center development while monitoring the economic and environmental effects of previously approved facilities.

Regulations are Fluid: Zoning isn’t static. Cities routinely revise their rules as new industries, housing needs, and community concerns emerge.
Assess Local Data: Buyers can review public parcel data, ownership records, and municipal tax maps directly through the Santa Clara County Assessor’s Office to better understand the industrial footprints near their targeted neighborhoods.

Frequently Asked Questions About

Bay Area Data Centers

Will a nearby data center affect my home’s property value?

There isn’t a responsible way to say that the presence of a data center will automatically cause nearby home values to rise or fall, as real estate values are influenced by a complex mix of location, inventory, interest rates, and school quality. You must evaluate how a specific development affects a specific property by looking at traffic, infrastructure, and approved plans. If you are evaluating properties and want to understand local market dynamics, browse active listings on our Willow Glen neighborhood guide.

How can I check if a data center is planned near a home I want to buy?

You should review environmental documents, check future phases of local technology parks, and actively follow City Council and planning updates for the specific municipality. For long-term school district boundary maps and how new commercial zones might affect them, refer directly to the San José Unified School District portal.
