The Department of Homeland Security (DHS) has recently acquired two major immigration detention centers in California, sparking a wave of controversy and concern. The purchases, totaling $1.5 billion, include the Otay Mesa detention center in San Diego and the California City detention center in Kern County. This move, aimed at thwarting state efforts to regulate private prisons, has raised questions about the future of oversight and conditions within these facilities.
The acquisition comes at a time when immigration enforcement has intensified, with ICE aiming to arrest 3,000 immigrants per day. The DHS spokesperson emphasized that the purchase ensures ICE retains the necessary detention capacity for its operations on the West Coast. However, experts and advocates fear that federal ownership may limit state and local oversight, potentially compromising the humanitarian conditions within these centers.
The Controversial Purchase
The Otay Mesa detention center, with a capacity of 1,994 detainees, has been a focal point of debate in San Diego for over a decade. Reports of poor nutrition, overcrowding, and inadequate medical care have plagued the facility. The DHS purchased the center for $739 million, nearly five times its estimated value of $160 million. Similarly, the California City detention center was bought for $733 million, ten times its estimated value of $71 million.
The funds for these purchases were allocated through the One Big Beautiful Bill Act, passed in July 2026, which provided DHS with $191 billion for immigration enforcement. This substantial investment has raised eyebrows, with Rep. Juan Vargas, D-Chula Vista, questioning the exorbitant cost. “To me, that seems ridiculously high,” Vargas remarked, expecting the purchase to cost between $200 million and $300 million.
Concerns Over Oversight and Conditions
Experts and advocates express grave concerns about the implications of federal ownership. Nancy Hiemstra, a professor at Stony Brook University, suggests that the primary motivation for DHS to buy these centers is to reduce transparency. “This is about adding layers of bureaucracy, so it makes it even harder for people to gain access to the facilities and to know what’s going on,” Hiemstra stated.
The California Department of Justice has conducted annual reviews critical of the centers’ conditions. A state law signed in 2026 grants local health officers the authority to conduct surprise health inspections. However, with federal ownership, state and local governments may be barred from conducting these inspections, similar to federal prisons, which are not subject to state law.
In, the county of San Diego sued the Trump administration after being denied access to tour the Otay Mesa facility. A judge later ordered CoreCivic to allow the inspection, but the report from the health inspector has not yet been released. The ongoing lawsuit highlights the tension between state authorities and federal agencies over the oversight of these facilities.
The Future of Immigration Detention
The DHS acquisition is part of a broader effort to increase detention capacity. A leaked memo from February 2026 revealed ICE’s plan to assemble tens of thousands of beds for detainees by purchasing large warehouses and converting them into makeshift detention centers. However, by June 2026, ICE backed away from these plans due to lawsuits concerning environmental costs.
Jason Houser, former chief of staff at ICE under the Biden administration, noted that the $1.5 billion deal acknowledges the challenges of the previous plan. “We realize that that plan’s not going to work,” Houser stated. The acquisition of existing detention centers, such as Otay Mesa and California City, aligns with ICE’s goal of streamlining the process from arrest to detention to deportation.
The purchase also raises questions about the revolving door between private prison employees and ICE leadership. David Venturella, the new acting ICE director, previously worked as an executive at the Geo Group, another private prison company. This interconnection underscores the complex relationship between private corporations and federal agencies in the realm of immigration enforcement.
As the debate continues, the future of immigration detention in California remains uncertain. The DHS acquisition of Otay Mesa and California City detention centers has ignited a firestorm of controversy, with experts and advocates calling for greater transparency and oversight. The implications of this move will likely resonate for years to come, shaping the landscape of immigration enforcement and detention in the United States.
