Chicago Is Becoming The World's LARGEST Data Center Market

Chicago's data center market is moving in the opposite direction of nearly every other major market in the country. While construction slowed or flattened in places such as Northern Virginia, Silicon Valley, Atlanta, and Hillsboro, Chicagoland saw a 169% jump in data center capacity under construction in a single year.

That is not a small shift. It is a billion dollar buildout driven by artificial intelligence, cloud computing, and the massive amount of computing power those technologies require. And because data centers need huge sites, dependable high voltage power, and room to expand, this is becoming a Chicago suburbs real estate story.

For homeowners and buyers, the implications are not simple. Some suburbs may gain stronger school funding, expanded infrastructure, and a commercial tax base that eases pressure on homeowners. Other neighborhoods may face construction disruption, noise, visual impacts, and concerns about electricity costs.

The important question is not simply whether a town has data centers. It is where the campus sits, where the home sits, and whether you are close enough to experience the downside while missing the broader community benefit.

Why Chicago Is Winning the Data Center Boom

Artificial intelligence has pushed data center demand into an entirely different gear. Cloud computing was already growing, but AI requires an extraordinary amount of processing capacity. That demand has created a race for sites that can support large scale, power intensive facilities.

Chicago has three advantages that are hard for other markets to replicate: land, power, and cost.

• Available suburban land: Large campuses need flat parcels with room for buildings, substations, generators, cooling equipment, and long term expansion.
• Competitive industrial electricity rates: ComEd has helped make the area attractive for power hungry development.
• Lower rental costs: Chicago has been identified as having some of the lowest rental rates among major global data center markets.

Illinois also gave developers a major reason to invest. The state's Data Center Investment Program, passed in 2019, offered qualifying projects exemptions from state and local sales and use taxes on servers, equipment, and construction materials.

To qualify, a development generally needed to represent at least a $250 million investment over five years and create at least 20 full time jobs. The program has been credited with helping bring more than $4 billion of investment into the state.

However, there is an important change to understand. Beginning July 1, Illinois paused new agreements under the incentive program. The decision came amid concerns over rising electricity demand, grid strain, and utility costs for consumers. Projects already holding agreements are not affected, but future development may look different if the incentive program does not return in its previous form.

That does not stop the wave already underway. It simply means the next phase of the boom may have a different shape.

Why This Is Happening in the Chicago Suburbs

Downtown Chicago is not where these massive facilities go. Data centers need acreage, transmission access, dependable power, and enough distance to build at industrial scale. That pushes development outward, especially along the I-88 and I-55 corridors.

The data center map is becoming clearer. Activity begins near O'Hare and pushes west through established industrial suburbs, then extends farther into DuPage, Kane, Will, and Kendall County communities.

Established and Active Data Center Areas

• Elk Grove Village
• Northlake
• Wood Dale
• Itasca
• Franklin Park
• Hoffman Estates
• Plano
• Joliet
• Minooka

These are not merely proposed projects floating around in local conversations. Major campuses are operating, under construction, approved, or in active planning stages across the region.

What Is Being Built Across Chicagoland

Elk Grove Village gives perhaps the clearest picture of what a mature data center market can look like. Stream Data Centers acquired 55 homes in a subdivision, paying approximately $950,000 per property, then demolished the homes to create room for a data center campus.

The village now has 20 operating data center facilities and another five under construction. Those facilities generated approximately $26 million in tax revenue in the most recently reported year, supporting schools, libraries, and parks. The surplus was large enough that residents received $400 water bill credits and $200 Visa gift cards following a public announcement in May.

That is what a substantial commercial tax base can do at the local level.

Elsewhere in the region, the activity is just as serious:

• Northlake: T5 Data Centers has a major facility under construction that topped out last year and continues toward completion.
• Wood Dale: CyrusOne is developing a 62 acre campus west of Route 83, planned for six data center buildings.
• Itasca: NTT Global Data Centers already operates a facility and has a long term campus strategy exceeding 200 megawatts.
• Franklin Park: Digital Realty has a 40 acre campus on Grand Avenue and is expanding its AI-ready footprint with additional Chicago area land purchases.
• Hoffman Estates: Compass Data Centers purchased the former Sears World Headquarters at 3333 Beverly Road for $194 million. The nearly 200 acre site is planned for five hyperscale facilities and roughly $10 billion in local investment.
• Plano: Microsoft acquired approximately 500 acres from three landowners. The farmland was annexed and rezoned for data center use, with site studies underway.
• Joliet: The Joliet Technology Center spans 795 acres and targets 1.8 gigawatts of capacity. Developed by PowerHouse Data Centers and Hillwood Development Company, the project is expected to involve about $20 billion in investment, with construction expected to begin in early 2027.
• Minooka: Equinix is developing its first Illinois hyperscale campus on former farmland, with plans for about seven buildings and approximately $25 million in community investments for roads, water, and sewer improvements.

Not every municipality is eager to approve these projects. Naperville rejected a proposed data center in a 6 to 1 vote, citing noise concerns and proximity to homes. Aurora imposed a 180 day moratorium in 2025 before adopting strict new data center rules in 2026.

That contrast matters. The development boom is real, but local resistance is real too.

Data Centers, Jobs, and Housing Demand

Data centers are not warehouses. The jobs associated with these facilities include engineering, network operations, IT, security, and highly specialized technical roles. The average data center employee in Chicagoland earns more than $142,000 per year.

High earning workers living in or moving into a community can support demand for larger, higher priced homes. At the same time, towns with a growing job base and strong commercial tax revenue often have a more resilient housing market than communities that rely heavily on residential property taxes.

The industry contributed roughly $25 billion to Illinois GDP in 2024. Still, it is worth keeping the jobs discussion realistic. Research from the Brookings Institution suggests that industry job claims can be overstated when they fail to separate new growth from economic growth that was already happening.

A more grounded estimate points to roughly 4% to 5% growth in total private employment in counties with a data center cluster, with clearer gains in information-sector employment and areas that host multiple facilities.

That is meaningful, but it does not mean every new campus suddenly transforms an entire local housing market. The real benefit is usually broader: better municipal finances, specialized employment, infrastructure upgrades, and a stronger commercial base over time.

Can Data Centers Help Home Values?

Most people immediately assume that a nearby data center hurts home values. The research from more established markets suggests the story is more complicated.

In Loudoun County, Virginia, one of the largest and most mature data center markets in the world, data centers contribute so much to the commercial tax base that the typical homeowner's annual property tax bill would reportedly be about $5,800 higher without them.

Illinois is not Loudoun County, at least not yet. But the direction is worth paying attention to.

The planned Joliet Technology Center is projected to generate approximately $2.1 billion in property taxes over its lifetime for the city and local school districts. Even the rejected Naperville proposal was projected to produce roughly $650,000 in annual property taxes from its first building, with about $500,000 directed toward local schools.

Data center campuses may also bring improvements that benefit a wider area:

• Expanded road capacity
• Upgraded electrical infrastructure
• Water and sewer improvements
• Additional funding for schools, parks, libraries, and municipal services

A study of 130 ZIP codes with large data center campuses found that fewer than 1% experienced declining home values over a five year period. Roughly two thirds matched or outperformed their state's appreciation rate. Research examining Northern Virginia home sales also found that properties closer to data centers sold for higher prices after other factors were controlled.

That does not guarantee Chicago suburbs will follow the same exact path. Northern Virginia has had decades to build an ecosystem around data centers. Chicagoland is still early in its expansion.

But the core point stands: a data center's presence may strengthen an entire municipality even if it is not ideal to live directly beside one.

The Tradeoff: A Stronger Town Does Not Mean Every Location Benefits

This is where the data center conversation gets real.

A home two miles away in the same school district may benefit from the commercial tax base, infrastructure investment, and municipal financial stability. A home whose backyard faces a generator bank or electrical substation is dealing with a very different experience.

There are three main concerns showing up repeatedly across Chicago suburbs: noise, electricity costs, and visual or construction impacts.

Noise Can Be a Serious Issue

Data centers run around the clock. Cooling systems, air chillers, industrial HVAC equipment, and backup diesel generators can produce consistent noise during the day and at night. Residents near facilities in Aurora described the sound as similar to a helicopter idling overhead every night.

Data centers can produce noise levels above 90 decibels, while prolonged exposure above 85 decibels can contribute to hearing damage. The issue is not just occasional construction noise. It can be continuous mechanical sound, especially when the surrounding neighborhood is quiet.

Illinois does not have a statewide minimum distance requirement separating data centers from residential areas. Aurora responded by setting sound limits of 56 decibels during the day and 46 decibels at night, adding vibration limits, and requiring city council approval for new projects.

Electricity Bills Are a Regional Concern

You do not need to live next door to a data center to care about grid demand. Illinois electricity bills rose approximately 15% from 2024 to 2025, more than twice the national average. Higher PJM capacity prices have been a major part of the increase, and data center demand has been linked to that pressure.

The Citizens Utility Board has warned that Chicago area electric bills could continue rising over the next several years. Its estimate suggests that the average ComEd customer could pay around $70 more per month by 2028.

Longer term projections have also raised concerns that data center load growth could add tens of billions of dollars to Illinois electricity system costs by 2050. State agencies have warned of potential power capacity shortfalls as early as 2029 in northern Illinois and 2031 in other parts of the state.

That is one major reason Illinois paused new data center incentive agreements. The state wants investment, but it also has to deal with grid reliability and consumer costs.

Scale, Appearance, and Construction Matter

These facilities can range from 50 acres to more than 800 acres. They often include security fencing, windowless concrete or steel buildings, large substations, cooling systems, and visible equipment near public roads.

Construction can take years. Stream's Elk Grove Village campus is projected to take up to a decade to build. Individual buildings may create two to four years of disruption, affecting traffic, noise, dust, and how nearby homes show when they are listed for sale.

A strong town budget is valuable. But if a home's immediate surroundings include industrial equipment, generators, construction activity, or a substation, that location needs to be priced and evaluated differently.

What Buyers Should Check Before Making an Offer

If you are buying in an active or emerging data center suburb, this is the due diligence that many buyers skip.

1. Review village and planning commission agendas. Data center proposals typically appear in planning commission packets, village board agendas, zoning notices, and local reporting before they become widely known. Look for nearby parcels being rezoned from residential to industrial or planned development.
2. Visit the property at different times. Go during the day, early in the morning, and later at night. Cooling equipment is often far more noticeable when traffic and neighborhood activity are quiet.
3. Identify the real noise sources. Do not measure only the distance to the main building. Find out where generator banks, cooling towers, substations, and mechanical equipment are located. Those elements may sit much closer to the campus edge.
4. Pay attention to ComEd substation activity. A new or expanded substation near a residential neighborhood does not automatically mean a data center is coming. Still, it can be an early indicator that substantial new power demand is expected.
5. Understand the construction timeline. A completed campus and an active multi-year construction site are completely different situations for daily living and resale timing.

What Sellers Near Data Center Hubs Need to Know

If you are selling in an established data center community, the town's commercial tax base can be a legitimate selling point. Buyers should understand the municipality's financial health, school funding position, public services, and infrastructure investment.

That information is part of the home's value proposition, not just a footnote about local taxes.

However, sellers need to be realistic if the home is directly affected by a campus. A property close enough to see, hear, or feel the impact of a facility may have a smaller buyer pool. If active construction is nearby, timing and pricing become even more important.

The goal is not to pretend the project does not exist. The goal is to position the home honestly, explain the larger municipal benefits, and price appropriately for the property's exact location.

Which Chicago Suburbs Are Most Affected?

Elk Grove Village, Northlake, Wood Dale, Itasca, Hoffman Estates, and Franklin Park are active or established data center markets where commercial tax revenue is already becoming part of the local picture.

Joliet and Minooka represent more of the next wave. The long term tax revenue could be substantial, but infrastructure demand and construction impacts may arrive before the broader financial benefits do.

For anyone comparing Chicago suburbs, that distinction is worth remembering. There is a real difference between buying in a town that benefits from data center investment and buying next to a data center campus.

Where the campus sits on the map and where the house sits in relation to it are two entirely different conversations.
