A massive AI data center campus is going up at 4801 E. Thistle Landing Drive in Ahwatukee, Phoenix — roughly 150 feet from existing homes. Developer Menlo Digital is building five buildings across 38 acres. Two are already standing. Residents organized under the Ahwatukee Community Alliance say they found out months late and want the city to act before three more buildings go up.
If you own or are buying a home near this site, here is what you are up against
Imagine standing in your backyard and looking at a facility with more than 100 diesel generators. That is the reality residents near Thistle Landing Drive are facing right now.
Resident Ana Marshall has lived in Ahwatukee since 2017. She put it plainly: “Would you like to buy a house 150 feet away from a data center?” That is not a rhetorical question. It is a disclosure question — the kind a buyer’s agent must raise and a seller dreads answering.
For current homeowners nearby, the daily concerns are real. Noise from cooling equipment and generators. Heat from a large industrial campus. Air quality worries tied to diesel exhaust. For anyone buying in south Ahwatukee, this campus is a material fact about the neighborhood.
The broader warning: the Valley’s data center boom is landing next to established neighborhoods. Your street may be near a Commerce Park zone. If it is, what happened here can happen to you — often without a public hearing and without advance notice.

Thirty-eight acres, five buildings, two already up: the scale of what’s being built
The Menlo Digital campus sits near 48th Street and Chandler Boulevard in the Ahwatukee Foothills area of Phoenix. The full project covers 38 acres and calls for five data center buildings. Organizers confirm two buildings are already constructed. Three more are planned.
Menlo Digital’s own materials state the campus will include more than 100 on-site diesel generators. The company says its substation is targeted for completion by end of 2026. The first data hall is expected in early 2027.
That timeline matters. Construction is moving faster than the regulatory process meant to govern it.

Five concerns Ahwatukee residents have organized around
The Ahwatukee Community Alliance — a formally organized 501(c)(3) nonprofit — has raised five specific concerns. Use this as a checklist if you live near any large data center site in the Valley:
- Noise. The Alliance commissioned an independent acoustic study and submitted it to the city on April 20, 2026. It documented predicted noise violations.
- Heat. Cooling systems for large data centers generate significant heat output near neighboring properties.
- Air quality. More than 100 planned diesel generators raise exhaust concerns for surrounding homes.
- Water use. AI data centers require large volumes of water for cooling — a real issue in the desert Southwest.
- Urban heat island effect. A large, heat-generating campus in a residential area can raise local temperatures over time.
The Alliance has also formally transmitted 31 written questions to Phoenix, demanding answers before permits advance. That puts their concerns in the official administrative record — not just at a protest rally.

‘We’re not against data centers’ — the Alliance’s actual argument
Craig Evans, chairman of the Ahwatukee Community Alliance, moved to the neighborhood in 1994. His argument is precise. The Commerce Park zoning that allowed this project was granted in 1996. A data center in 1996, he says, “was a very different thing than it is in 2026.”
Evans and the Alliance are not calling for a ban on data centers. They question whether a campus this size belongs next to homes. More than 100 diesel generators and industrial heat output are not what neighbors signed up for. That argument is harder to dismiss than blanket opposition.
Phoenix recognized the problem. In July 2025, the city adopted Ordinance G-7396. That ordinance created the city’s first formal zoning definition for data centers. It required noise studies and a 150-foot setback from residential areas. The catch: Menlo received preliminary approvals in 2024 and is explicitly not covered by the new rules.
How residents were left in the dark until shovels were already in the ground
The Thistle Landing site has been zoned Commerce Park and General Commerce Park since 1996. Before July 2025, Phoenix treated data centers the same as office buildings in that zone. That meant Menlo needed no rezoning — and no public hearing — before construction could begin.
Many neighbors say they did not learn about the project until months after planning had started. One resident noted that people did not realize it was a data center until around springtime. By then, two buildings were already going up.
The new ordinance was designed to close that gap. It came too late for Ahwatukee. If your street is near a Commerce Park zone, check what is permitted there now. Don’t wait until construction starts.

The November air quality hearing — and what still has to happen
Construction is underway, but the project is not fully permitted. As of late August 2026, outstanding city permits remain unresolved. A Maricopa County Air Quality Department hearing is expected in early November 2026. That hearing will cover diesel generator permit applications for all five buildings.
County Supervisor Mark Stewart pressed air quality officials to require Menlo to resubmit those applications. That gave residents another formal opportunity to weigh in.
The Alliance has already submitted its acoustic study and its 31 questions to the city. Both are now part of the official record. Whether those submissions slow or stop further construction depends on what city and county officials decide in the coming weeks.
For Ahwatukee homeowners, the November hearing is the clearest near-term chance to influence what gets built next door. For Valley homeowners watching from elsewhere, this story shows how industrial-scale development can arrive in a residential neighborhood — fast, and without early public notice.
