Should local governments compensate property owners when new zoning laws decrease land values?
A Maricopa County Superior Court judge has ordered the city of Phoenix to provide evidence justifying its 2025 data center zoning ordinance. The legal challenge stems from a lawsuit filed by West Buckeye Road LP, which alleges the ordinance limits land use and diminishes property values.
Why it matters
The case tests the balance between local infrastructure mandates for data centers and private property rights protected by state law. If Phoenix fails to prove the necessity of these requirements, it could set a precedent for how municipalities regulate high-density industrial tech projects.
The city mandate requires data center developers to install specific cooling equipment and soundproofing panels. The unresolved question is the technical threshold of what constitutes a public health necessity for these infrastructure installations.
The players
West Buckeye Road LP
An industrial real estate developer currently contesting Phoenix's land-use ordinances.
Phoenix
The municipality managing zoning regulations for industrial technology infrastructure.
The details
The dispute centers on a 2025 zoning ordinance that forces data center projects to integrate noise-mitigation and climate-control infrastructure. West Buckeye Road LP argues that these restrictions hinder development on industrial land acquired in 2021, claiming losses of $54 million. The court must now determine if these standards meet the legal burden of protecting the public, as defined by existing state property law.
Timeline
2006: Arizona voters approved the Private Property Rights Protection Act.
2021: West Buckeye Road LP purchased industrial land in Phoenix.
2025: Phoenix adopted the data center zoning ordinance.
October 2026: A judge dismissed one challenge against the city.
November 17, 2026: Evidentiary hearing regarding ordinance necessity.
The Tech Race
This case marks a test of the 2006 Private Property Rights Protection Act's reach regarding city-mandated industrial infrastructure standards. It pits local regulatory authority against the rights of property owners developing high-density tech sites.
The ruling will determine whether developers must adhere to costly soundproofing and cooling requirements for upcoming data centers in Phoenix. Future industrial land use and property values in the area depend on the upcoming court decision.
The takeaway
The court's decision will clarify whether Phoenix can enforce specialized infrastructure mandates on private industrial projects. Stakeholders should monitor the November 17, 2026, evidentiary hearing to gauge the future of local zoning for high-density tech facilities.
What happens next
A judge will hold an evidentiary hearing on November 17, 2026, to determine if the city's infrastructure ordinance is essential for public health.
