Arizona Attorney General Kris Mayes said the state reached a stipulated agreement with the U.S. Department of Homeland Security and ICE to pause efforts to convert a Surprise property into an immigration detention center.
The announcement follows an April 2026 lawsuit by Mayes’ office. The lawsuit alleged federal agencies moved forward on the Sweetwater Avenue facility without completing environmental review required under the National Environmental Policy Act (NEPA).
Under the agreement filed June 30, 2026, and pending court approval, the federal government agrees not to detain people at the facility and not to take steps to physically convert it. That includes construction, demolition, or retrofitting, until a final environmental assessment is completed.
The stipulation also pauses the litigation while the environmental review is carried out. The state says it may challenge whether the review is adequate if needed.
People in Surprise and anyone affected by detention plans tied to the facility may see delays while the environmental process is completed. For the most accurate details, readers should review the filed stipulation and any court order approving it on the official Arizona Attorney General website.
