A coalition of Oregon residents and an advocacy group has taken the City of Hillsboro to court over agreements tied to data center growth. The case asks whether local officials followed the law when approving data center tax breaks. For residents and businesses watching public budgets, the outcome could matter well beyond one city.
What the Lawsuit Claims
1000 Friends of Oregon, joined by farmers, local leaders, and businesses, filed a petition against the City of Hillsboro on June 22, 2026. The petitioners argue that the city, along with Washington County, improperly issued approvals required for property tax exemptions connected to 17 data center applications. The matter was brought as a writ of review proceeding in Washington County Circuit Court.
The plaintiffs are represented by attorneys from Willamette Law Group, 1000 Friends of Oregon, and Crag Law Center.
The Money at Stake
The figures are large. The city forgoes an estimated $71.0 million to $75.5 million each year in real property taxes on active data center buildings, plus $46.3 million to $49.4 million annually in personal property taxes. Combined, the abated amounts reach a reported $117.3 million to $124.9 million per year.
Those estimates were published by the Hillsboro Herald, which has tracked the deals closely.
Supporters of the lawsuit tie those numbers to local services. Their stated concerns include:
- School closures and teacher layoffs
- Higher water and energy costs for residents
- Pressure on farmland and local watersheds
- Agreements that extend for decades, some reaching 2051
The Legal Question
At the center of the dispute is how the approvals were granted. The challenge focuses on 17 Enterprise Zone applications the city approved under the Oregon Enterprise Zone Act, a state program meant to encourage investment in communities facing economic hardship.
The petitioners argue that the way these zones were structured strays from that purpose. One plaintiff contends the program linked wealthier industrial areas with lower-income neighborhoods to qualify for subsidies, without delivering the intended benefit to the communities used to justify them.
A writ of review is a specific procedural tool. It asks a court to examine whether a local government followed proper legal standards when making a decision. If the court finds the approvals were issued improperly, it can send them back for correction.
Why This Case Reaches Beyond Hillsboro
Data center development is expanding across Oregon and other states. Many of these projects rely on data center tax breaks negotiated at the local level. A ruling here could shape how other cities handle similar agreements and how closely residents review them.
