A Facebook post about data centers near a Mesa listing kicked off a real debate this week. One agent's clients fell in love with a house in East Mesa, then found out five data centers are planned nearby and got cold feet. The post claimed 200 data centers are coming to Arizona, and the comments split fast: agents who think buyers deserve to know, and agents who think it's not realistic to research every industrial project within five miles of a listing. Both sides have a point, and the actual numbers are worth knowing regardless of where you land.
What's actually happening: depending on how you count, that 200 figure isn't far off. A 2026 ASU study found 66 data centers completed or under construction across Central Arizona counting large-scale campuses specifically. Sites that track every colocation and cloud facility, like datacentermap.com, count over 180 in the Phoenix market alone. East Mesa is genuinely one of the biggest data center hubs in the country right now, with active or expanding campuses from Meta, Google, NTT, and Apple. Meta's site alone is 2.5 million square feet. NTT paid $300 million for 173 acres to build a 2.2 million square foot campus.
The concerns are documented, not invented. Water is the biggest one in Arizona. Mesa's vice mayor has publicly called data center water use "irresponsible" during the driest 12-month stretch the state has seen in 126 years. Mesa, Avondale, and Phoenix have all passed ordinances capping industrial water use.
Is it an agent's job to bring this up? Arizona disclosure law requires sellers to disclose known material facts, but there's no line item for "data center nearby." That's a judgment call, not a checklist, and I don't think there's a clean answer.
Is it actually bad for home values? Arizona data centers generated $863 million in state and local tax revenue and supported over 81,000 jobs in 2023. Homes within 5 to 15 miles of major data center campuses in the Phoenix East Valley have shown an 8 to 18% price premium since 2022, though that's likely correlation more than causation. What the research does show is that proximity is what matters. Homes right next to a construction site can take longer to sell, but a few blocks away the effect mostly disappears.
If you're house hunting near a proposed site, ask specifically what's planned within a mile. Want to check a specific address yourself? datacentermap.com/usa/arizona/phoenix tracks known facilities across the Valley.
