ICE Arrests in the SF Bay Area Surge Nearly 70 Percent, New Data Reveals
Finn's Take· TL;DR- ICE arrests in San Francisco Bay Area surged 70 percent to nearly 5,000 in first seven months of 2026 compared to 2025.
- Majority of detained immigrants lack criminal convictions; enforcement shifted to community arrests versus jail-based operations, increasing tenfold from prior administration.
- Despite California sanctuary laws limiting local cooperation, federal monitoring expanded to over 20,000 individuals in Bay Area, creating widespread climate of fear.
A Sharp Rise in Immigration Enforcement
New data from UC Berkeley's Deportation Data Project is painting a stark picture of immigration enforcement in the San Francisco Bay Area. From January through July 2025, ICE made 2,928 arrests in the region. During the same period in 2026, that number climbed to 4,970 — a jump of nearly 70 percent. The figures are reshaping daily life for immigrant communities across one of the country's most diverse metro areas, and they're raising pointed questions about who is being targeted and why.
"We're at a rate of deportations that's at about five times where it was under the Biden administration," said David Hausman, co-director of the Deportation Data Project and an assistant professor of law at UC Berkeley. That comparison alone underscores just how dramatically the enforcement posture has shifted. And July was a particularly striking month: ICE arrested 982 people in San Francisco in July alone, the highest monthly total since the project began releasing data.
Who Is Being Arrested — and Where
Perhaps the most significant shift isn't just the volume of arrests, but where and how they're happening. Hausman noted that the types of arrests being made have changed dramatically. "Arresting people out in the community or at check-ins is really a new thing in the sense that it was really uncommon before this administration," he said, adding that the rate of arrests not happening at jails or prisons has gone up by over ten times.
The profile of those being arrested has also shifted. Despite administration rhetoric emphasizing dangerous criminal offenders, data shows ICE held 65,765 people in immigration detention as of July 11, 2026, and 70.6% of them had no criminal convictions. Nationally, ICE arrests hit a record 49,571 in a single month in July 2026 — a 70% increase from the roughly 29,241 arrests recorded in February 2026.
The Bay Area's Unique Position
San Francisco has long operated under California's sanctuary laws, which limit local cooperation with federal immigration enforcement. Experts attribute relatively lower arrest rates in Northern California to the state's sanctuary law, as well as community resistance and supportive local policies. Yet the new numbers make clear that federal enforcement has found ways to reach deeper into the region regardless. ICE has made at least 2,440 arrests in San Francisco since President Trump's second term began — the fourth-highest number of arrests for any California city from January 20, 2025, through July 31, 2026, according to a Chronicle analysis of the Deportation Data Project's data.
The agency's Alternatives to Detention programs were monitoring 183,181 individuals and families nationwide as of July 11, 2026, with the San Francisco area office leading the country at 20,804 monitored individuals. That means the reach of enforcement extends far beyond formal arrests — thousands more in the Bay Area are under active federal supervision, a reality that advocacy groups say creates a pervasive climate of fear even for those who have not been detained.
What Comes Next
The data, processed through UC Berkeley's Deportation Data Project, represents one of the most transparent public windows into ICE enforcement activity — and researchers say it likely undercounts the full scope of operations. The tally is considered an undercount of total immigration arrests under Trump, as it only included ICE. Other federal agencies, including Border Patrol, have also conducted deportations in the state.
With monthly arrest totals continuing to climb nationally and the San Francisco field office among the most active in the country, Bay Area immigrant communities and their legal advocates face an intensifying challenge. The data gives advocates a clearer picture of enforcement patterns — but for families navigating this reality on the ground, numbers only tell part of the story. The human cost of this surge, measured in disrupted lives and fractured households, will take much longer to fully account for.
