A proposed data center does not automatically mean a home will lose value, become noisier, or face higher electricity bills. The outcome depends on the specific project, its approval status and infrastructure, local conditions, and what you can observe from the property. Before making an offer, verify the local records, assess the site and utility plans, and compare nearby homes using local market evidence.
What a nearby data center could mean for a home
There is no reliable universal “data-center effect” that predicts the value of an individual home. A facility could matter to buyers through factors such as noise, views, construction, traffic, utility infrastructure, or perceptions of the area—but the effect, if any, depends on the property and local market.

The National Association of REALTORS® (NAR) cautions that its county-level comparisons cannot show what happens to a home next to a data center. Counties with many facilities can differ from other counties in jobs, housing supply, geography, and market conditions. In Virginia, the Joint Legislative Audit and Review Commission (JLARC) reported in 2024 that it had not found evidence of a relationship between data centers and property values in its review; its discussion also included interview evidence, not a causal home-price study.
That means neither a guaranteed discount nor a guaranteed resale penalty is established. For a particular home, local comparable sales, current listings, buyer demand, and direct observations are more useful than a national or county average.

What broad statistics can—and cannot—tell you
The figures below describe patterns or reported perceptions, not predictions for a particular address. NAR’s figures are from its 2026 coverage; JLARC’s noise and proximity figures are from its 2024 Virginia review.
| Measure | Reported figure | How to interpret it |
|---|---|---|
| County distribution | NAR reported that 92% of more than 3,200 U.S. counties it tracked had no mapped data centers, while 1% had 10 or more. | This describes where facilities were mapped, not exposure at an individual home. |
| Median home values by county group | NAR reported $174,500 in counties with no data centers and $431,750 in counties with 10 or more. | NAR cautions that the difference does not show data centers caused higher values; the county groups and their markets differed. |
| Residential electricity rates | NAR reported rates rose 21.4% from 2020 to 2024 in counties with 10 or more data centers, compared with 15.7% in counties with none. | This is a county-level association; it does not establish that a facility caused an individual household’s rate increase. |
| Agents’ perceptions of nearby home values | In NAR’s 2026 survey, 25% of agents perceived a positive effect and 22% a negative effect; about one-third were unsure. | These are agent perceptions, not measured sale-price effects. |
| Agents’ perceptions of residential demand | In NAR’s 2026 survey, 26% said nearby demand decreased, 27% said it did not change, and 19% reported an increase. | Survey responses do not predict demand for a particular home. |
| Noise readings at complaint-related sites | JLARC reviewed selected data-center noise measurements estimated at 40 to 59 dBA. | The readings came from sites with resident complaints, were not representative of all data centers, and measured total sound rather than an isolated facility contribution. |
| Proximity to residential areas in Virginia | JLARC found one-third of Virginia data centers were near residential areas. | The analysis covered eight localities accounting for nearly all Virginia data centers; it should not be generalized to the United States. |
NAR also reported that surveyed agents said clients’ concerns involved energy costs (61%), water use (56%), perceived environmental contamination (43%), and changes to the immediate landscape (32%). These percentages describe reported concerns, not verified project impacts.
Check what is actually proposed and approved
A public announcement, property purchase, or land-sale agreement is not necessarily approval to build. Find the exact project and parcel, then determine which approvals have been requested, granted, appealed, expired, or left conditional. Ask the listing agent and local planning staff for the project name, parcel numbers, developer, and planning case number, and review the underlying records rather than relying on a headline or summary.

Look for zoning applications, site plans, staff reports, hearing notices, meeting minutes, permits, and recorded land agreements. Also check the comprehensive plan and zoning rules for nearby parcels: they can help show what other uses or future facilities may be possible, though they do not prove that another project will be built.
Approval can be split among agencies. For example, the City of Page, Arizona, says its approved land-sale agreement did not itself approve a data center, zoning, development, or utilities; a project would need separate development approvals. Tennessee’s Department of Environment and Conservation likewise says its environmental permits do not approve a data center project as a whole; local siting and zoning, noise, grid planning, and utility capacity involve other authorities. These are local examples, not rules to apply in another jurisdiction. Identify the equivalent decision-makers where the home is located.

Inspect the full site and infrastructure plan
The main building is only one part of a project. Use parcel maps, aerial imagery, planning drawings, and site visits to understand what may sit between the home and the facility, and what could be closer than the building itself.
- Exposure: Note distance, elevation, sightlines, intervening buildings or trees, and whether equipment or roads would be visible from the house or yard.
- Power: Look for proposed substations, transmission routes, and construction areas; ask how planned capacity, costs, and rate structures are addressed.
- Water and wastewater: Ask providers about the proposed water source, requested or approved volumes, peak demand, cooling method, discharge, sewer capacity, and drought contingencies.
- Other site effects: Review plans for backup generators, fuel storage, lighting, stormwater, wetlands, air and wastewater permits, access roads, and construction activity.
- Future phases: Check whether drawings or approvals describe later buildings or related infrastructure, and whether expansion would require further review.
Planning toolkits commonly group these questions under infrastructure capacity, land use, fiscal impacts, zoning, and legal review. The responsible agencies and records vary by location. An environmental permit, by itself, should not be taken as proof that every aspect of the land use or project has been approved.
Evaluate noise in context
JLARC describes residents reporting a steady, low-frequency “drone” or “hum.” Whether sound carries to a particular home depends on factors including facility design, cooling technology, geography, and nearby buildings. A sound may be persistent without being acutely loud, and the existing background—such as road, rail, or industrial noise—can affect what you hear.
If practical, visit at different times, including a quiet evening or overnight period. For a proposed facility that is not operating, ask whether the local authority requires baseline, pre-construction, or post-construction noise studies. Review where measurements were taken, what operating conditions were modeled or measured, whether tonal or low-frequency sound was assessed, which limits apply, and how complaints are handled.
A handheld sound-level meter can help you make repeatable personal observations, but its reading cannot identify the sound source, isolate a facility’s contribution, or establish legal compliance. If noise is central to your decision, ask the local authority about required studies and consider qualified acoustical help.

Compare local market evidence
Ask an agent or appraiser to compare similar homes at different distances from existing facilities, where possible. A useful comparison accounts for neighborhood, property condition, schools, commute, sale date, inventory, time on market, and broader market conditions. Examine both completed sales and current competing listings; a small or dissimilar sample may not support a confident conclusion.

NAR director of business and consumer research Matt Christopherson said the effect “can vary market to market and even within the same region,” and is “more dictated by local market conditions than solely if there is a data center or not.” Treat broad county patterns as context, not as a substitute for evidence about the home you are considering.
Use the same checklist to compare homes or proposals
If you are choosing between two homes or evaluating alternative project plans, compare them on the same dimensions rather than focusing only on distance to the main building.
- Approval certainty: zoning and permit status, conditions, appeal risk, and the review required for future phases.
- Proximity and exposure: distance to buildings and ancillary equipment, visibility, topography, and intervening structures.
- Noise: expected sources and hours, study methods and modeled levels, complaint process, and enforceable local standards.
- Utilities and environmental conditions: power routes and allocation, water source and demand, cooling, wastewater, stormwater, generators, and construction impacts.
- Local market evidence: comparable transactions, demand, inventory, days on market, and the strength of the available sample.
- Personal fit and resale flexibility: quiet enjoyment, outdoor use, view, commute, likely buyer preferences, and your time horizon.
Make the decision around your own tolerance and exit plan
Consider whether you would still want the home if the project became more visible, construction continued for an extended period, or an expansion were approved within the applicable rules. Decide which changes would affect your daily life and what evidence or project conditions would make you comfortable proceeding. Discuss contract contingencies and disclosure questions with an appropriate local real-estate or legal professional; the relevant rules depend on the jurisdiction and transaction.
