The lawsuit over the ICE detention center planned for Roxbury, New Jersey is still open and has not settled. The State of New Jersey and the Township of Roxbury sued the Department of Homeland Security and Immigration and Customs Enforcement in March 2026 to block conversion of a 470,000-square-foot warehouse at 1879 Route 46 into a facility holding up to 1,500 immigration detainees. In May 2026, the federal government agreed to pause construction and complete an environmental assessment it had skipped, and the case has been quiet on the docket since.1Civil Rights Litigation Clearinghouse.

What the Lawsuit Claims
The 67-page complaint, filed March 20, 2026, names ICE, DHS, DHS Secretary Kristi Noem, and acting ICE Director Todd M. Lyons. It alleges violations of four federal statutes:7NJ Office of the Attorney General. Complaint, State of New Jersey v. U.S. Immigration and Customs Enforcement
- The Administrative Procedure Act, because the siting decision was allegedly arbitrary and capricious and ignored impacts on local infrastructure, public health, and the environment.
- The National Environmental Policy Act, because DHS never prepared an Environmental Impact Statement or Environmental Assessment.
- The Intergovernmental Cooperation Act, because the federal government did not coordinate with state and local officials on a project with significant community impact.
- The Immigration and Nationality Act, because the warehouse is allegedly not an “appropriate” place of detention, lacking the infrastructure for human habitation and violating local zoning and building codes. At the time of purchase, the building had four toilets, one urinal, and five wash basins.
The plaintiffs ask the court to vacate the decision to establish the facility and to permanently enjoin further construction.
Why Roxbury Sued
DHS purchased the warehouse in February 2026 for approximately $129 million and planned to finalize renovation contracts by the end of March, complete construction within 90 days, and begin operations as early as June 2026.8New Jersey Monitor. NJ, Roxbury Sue Trump, ICE Over Warehouse7NJ Office of the Attorney General. Complaint, State of New Jersey v. U.S. Immigration and Customs Enforcement The planned 1,500-detainee, 1,000-staff operation would land in a township of about 23,000 people served by 42 police officers, a volunteer fire department, and two ambulances.
The complaint says converting the building would push wastewater production to more than 15 times the site’s current approved limit, risking sewage overflows into Lake Musconetcong and Lake Hopatcong. The site sits in the Highlands region, which supplies roughly 70 percent of New Jersey’s drinking water, and the plaintiffs argue the facility’s water demand could reduce pressure for residents and impair firefighting.9NJ Office of the Attorney General.

The complaint also projects nearly 500 additional vehicle trips during the morning rush on a stretch of Route 46 near the Interstate 80 interchange that has a history of fatal crashes, and estimates a loss of roughly $1.8 million in annual property tax revenue because the federal government does not pay local property taxes.8New Jersey Monitor.

What Happens Next
The next real signal will come from the joint status reports the court has ordered. If the Environmental Assessment finds significant impacts, or if the government tries to resume construction without completing it, the plaintiffs have said they will return to court to seek immediate relief.11State Impact Center. New Jersey AG Filed Lawsuit Against DHS and ICE Over Alleged Legal Violations in Conversion of Warehouse to Immigration Detention Facility A parallel case offers one data point on how courts have treated similar projects: in March 2026, a federal judge in Maryland issued a temporary restraining order pausing a similar warehouse-to-detention-center conversion in Williamsport, citing environmental concerns.12Washington Post.
