Salt Lake City and its county have filed a lawsuit seeking to block the Department of Homeland Security’s plan to open a giant warehouse in the city that would be used to detain up to 10,000 immigrants.

The lawsuit, filed Monday in federal court, is the latest brought by local officials around the country who were not consulted before DHS purchased industrial warehouses that it planned to convert into regional immigrant processing and detention centers.

The lawsuit targets the most expensive property purchased by DHS for the initiative: $145.4 million for a 833,000-square-foot (77,388-square-meter) warehouse that is roughly the size of 15 football fields. The March purchase, from a real estate development group partially owned by Deutsche Bank, cost nearly 50% more than the property’s 2025 assessed market value, records show.

In all, DHS purchased 11 warehouses for more than $1 billion between January and March in the final weeks of Homeland Secretary Kristi Noem’s tenure under her $38.3 billion plan for a new detention model to increase bed capacity and make deportations more efficient. The DHS Office of Inspector General has opened an investigation into whether the plan was wasteful, and Noem’s successor, DHS Secretary Markwayne Mullin, has put it on hold.

Like others filed around the country, the lawsuit in Utah alleges DHS violated federal law by failing to conduct required environmental reviews or get input from state and local officials before the purchase.

“This kind of facility has no place in Salt Lake City, not only due to its inhumane nature but also because of our limited water supply, the increased strain on public utilities systems, and the potentially drastic public health and safety impacts it would have on our residents,” Salt Lake City Mayor Erin Mendenhall said in a statement.
