Is it safe to live near a data center?

Living near a data center is generally safe, but it can bring real, daily nuisances that wear on your quality of life. The biggest, best-documented problem is noise. Beyond that, neighbors raise concerns about air from backup generators, strain on local water and power, and worries about home values.

These are not doomsday risks. A data center will not poison your street overnight. But the effects are real, they are close to home, and they can last for years. Communities from Arizona to Virginia have fought over them.

There is also a new twist. Some data centers are now tied to their own nuclear power plants to feed their huge appetite for electricity. That adds fresh fears about radiation, which we cover honestly below. First, the everyday issues.

Noise: the constant hum

The most common complaint from people near data centers is noise: a steady, low hum that never fully stops. The sound comes from thousands of cooling fans running around the clock to keep servers from overheating. Unlike traffic, it does not pause at night.

The numbers help explain why. According to the Environmental and Energy Study Institute, background noise in these areas often runs 45 to 50 decibels, but a warehouse of servers can push levels up to 96 decibels. Diesel backup generators can hit about 105 decibels when they run, as loud as a jet passing overhead.

Real neighborhoods have felt this. In Chandler, Arizona, residents of the Brittany Heights community complained for years about a constant hum from a nearby data center that started operating in the mid-2010s. The city later passed a zoning rule, effective in early 2023, requiring sound studies and noise checks before and after a data center is built.

Virginia has seen the fiercest fights. In Loudoun County, the noise limit in residential areas is 55 decibels, yet neighbors report the low, tonal drone still gets through walls. Prince William County added new enforcement in 2026 aimed at the exact "steady tonal noise" that data centers and their generators produce. Some residents have said they cover windows just to sleep.

Generator testing adds to the strain. Data centers run their diesel backups on a schedule to make sure they work, so neighbors hear loud test runs on top of the daily hum. If a facility is proposed near you, ask how far it will sit from homes and what noise walls or barriers are planned.

Air quality and diesel generators

Data centers keep rows of diesel backup generators, and testing or running those engines can release pollution near homes. The generators exist to keep servers online during a power outage. But they burn diesel, which puts soot and gases into the air.

Diesel exhaust contains fine particulate matter and nitrogen oxides. Health agencies link long-term diesel exposure to heart and lung disease and cancer. For most neighbors the day-to-day risk is low, because the generators are backups, not constant power. The concern grows where many generators sit close to homes and run often.

Permitting is where critics see a gap. The U.S. Environmental Protection Agency sets standards under the Clean Air Act, and new generators are generally expected to meet strict "Tier 4" limits for soot and nitrogen oxides. But state and local agencies issue most permits, and the rules have loopholes.

Reporting has shown some large projects sidestepping tougher review. In Texas, regulators let some data centers, including one tied to the Stargate project, obtain minor air permits, the kind more common for dry cleaners, rather than the major permits used for big pollution sources. That means less public scrutiny of what neighbors breathe.

If a data center is planned near you, ask what tier the generators meet, how many there are, and how often they will run for testing. Ask whether it holds a minor or major air permit. Those answers tell you a lot about the air-quality risk.

Water and power strain

A large data center can use as much electricity and water as a small city, straining the grid and local supplies your community shares. Servers make heat, and many centers use water for cooling. They also draw enormous amounts of power to run day and night.

Water is the more local worry. Some cooling systems evaporate millions of gallons a year, which can matter a lot in dry regions already short on water. That water competes with homes, farms, and businesses. Newer designs use less, but not all do, and communities often learn the real numbers only after approval.

Power strain hits your wallet too. When a giant new user plugs into the grid, utilities may need costly upgrades, and those costs can land on everyday customers. We break this down in our guide on whether data centers raise electric bills. In several states, regulators are now studying whether ratepayers are subsidizing data centers.

None of this makes a data center unsafe to live beside. But it does mean the facility can quietly reshape your town's resources. For the fuller picture of local costs and benefits, see our overview of data center community impact.

Property values: the evidence

The evidence on property values is mixed: most homes near data centers hold their value, but houses right next to one can sell at a discount. This is one area where fear often runs ahead of the data. The honest answer depends heavily on distance.

A 2025 study from the Schar School of Policy and Government at George Mason University looked at Northern Virginia, the world's largest data center hub. It found home prices were generally higher, not lower, the closer a home sat to a data center, likely because those areas also have strong job markets and infrastructure.

But zoom in to the property line and the picture changes. Case studies in the same region found homes within a few hundred feet of a hyperscale data center listing at rough discounts of 15 to 18 percent compared with similar homes farther away. A home just over a mile away showed little to no penalty. Immediate adjacency, with its noise and views of concrete walls, is the real risk.

So the fair takeaway is this: a data center a mile away is unlikely to sink your home's value, and may sit in a growing area. A center looming right across the street is a different story. If you are buying, weigh the exact distance, the noise, and the view, not just the word "data center."

The nuclear plant next door

A new twist is that some data centers are now tied to nuclear power plants, which raises fresh fears about radiation. To feed AI's power hunger, tech firms are signing deals for nuclear electricity. The most famous is Microsoft's plan to help restart the Three Mile Island plant in Pennsylvania under a 20-year deal, targeted for around 2028.

So is it safe to live near a nuclear power plant? For decades, the mainstream scientific finding has been reassuring. A landmark 1990 study by the National Cancer Institute found no higher cancer death rates in counties with nuclear plants than in similar counties without them. A normal, running plant exposes neighbors to a tiny radiation dose, far below what you get from nature each year.

The science is not perfectly settled, and we will not pretend it is. A 2026 study in Nature Communications found a statistical link between living closer to a U.S. nuclear plant and higher cancer mortality. Importantly, the authors themselves stress this is an association, not proof of cause, and other factors could explain it. It reopens a question rather than settling one.

What is concrete is the planning. The U.S. Nuclear Regulatory Commission requires two emergency planning zones around every plant: a roughly 10-mile zone focused on airborne releases, and a roughly 50-mile zone focused on food and water. Within these zones, officials plan for sheltering, evacuation, and potassium iodide pills if a serious accident ever happened.

The bottom line: living near an established nuclear plant carries a small, much-studied risk that most experts consider low, not the disaster many people imagine. Newer reactor plans deserve more scrutiny, since some are unproven. See our pillar on nuclear data centers and our look at whether small modular reactors are safe.

What you can do

You can push back on a data center by organizing early, demanding real studies, and holding local officials accountable. Communities across the country have slowed, shaped, or stopped projects. The key is acting before the zoning vote, not after the concrete is poured.

Start by learning the plan. Ask for the noise study, the air permit, and the water and power estimates in writing. Demand setbacks from homes, sound barriers, and Tier 4 generators. Insist on post-construction noise checks, like Chandler now requires. Show up to planning meetings, since local boards decide most of these fights.
