Bay Area ICE Activity Tracker

A 1-100 score for confirmed immigration enforcement in the Bay Area over the last 14 days, with the formula and every source. We count only incidents confirmed by named news outlets or named officials and organizations. Social-media posts and rumors never count.

By the Bay Area Brief staff · Edited by Seamus McKenna · Last updated Oct. 31, 9:40 a.m. PT

Advisory: Immigration enforcement activity in the Bay Area is at its highest level on our tracker. If you or your family may be affected, consider limiting travel to what is completely necessary.

Know your rights if you are stopped or questioned: ACLU of Northern California know-your-rights guide. This advisory is based on the confirmed, sourced reports listed below on this page.

Where it’s happening

Why the score is high: 14 confirmed arrests in 6 counties over 14 days, mostly single arrests rather than large sweeps.

Contra Costa County: San Pablo (2 arrests, Oct. 21)
Marin County: San Rafael (2 arrests, Oct. 27)
San Francisco: San Francisco (1 arrest, Oct. 19)
Santa Clara County: San Jose (1 arrest, Oct. 20), San Jose / Milpitas (ICE seen, no arrest, Oct. 25), Milpitas (ICE seen, no arrest, Oct. 28)

Score (raw 146, kept between 1 and 100)		100

The formula

Score = points from confirmed incidents only, rounded, then capped between 1 and 100. Each confirmed arrest in the last 7 days: 10 points. Each confirmed arrest 8 to 14 days ago: 4 points. Confirmed enforcement activity with no confirmed arrest (for example, a school district or county confirming agents were present): 2 points in the last 7 days, 1 point 8 to 14 days ago. Each incident involving several people in one action, or a checkpoint: +8 (last 7 days) or +3 (8 to 14 days ago). Each confirmed large-scale operation (10+ arrests in one action, a multi-site sweep or a workplace raid): +25 (last 7 days) or +10 (8 to 14 days ago). Each distinct county with a confirmed incident in the last 14 days, after the first: +4. Rumors, unverified sightings and debunked reports: 0 points. Older than 14 days: 0 points.

Words under the number: 1+ No confirmed activity · 2+ Minimal · 10+ Limited · 30+ Moderate · 50+ Elevated · 75+ High. Last 7 days = Oct. 25 to Oct. 31; 8 to 14 days ago = Oct. 18 to Oct. 24. An incident counts only when a named news outlet or a named official or organization confirms it; social-media posts never count. The score is recalculated every time the site is rebuilt, so incidents lose points as they age.

Confirmed incidents, last 7 days

Oct. 28 · Milpitas
Federal immigration agents waited outside Elmwood jail in Milpitas as people were released Wednesday night; the Santa Clara County Sheriff's Office confirmed an increased ICE presence at Elmwood and the Main Jail and said people are being stopped, questioned and sometimes apprehended after release. The county's Rapid Response Network said ICE detained four men and Tasered one, who was taken to a San Jose hospital (Milpitas confirmed a medical call); his custody status and the detentions were not independently confirmed, so this counts as confirmed presence only.

Context

Orinda: city officials said ICE arrested one person in Orinda on Friday, Oct. 30, in a targeted operation tied to a criminal arrest warrant, which ICE's San Francisco office confirmed to the city; the city reported no ongoing enforcement. Only one outlet has reported it so far, so it is not scored yet. Patch (Oct. 30, 2026)
Santa Clara County: after a week of ICE officers waiting outside Elmwood jail in Milpitas as people were released, the Sheriff's Office restricted access to Elmwood's parking lot and lobby on Oct. 30 to people with direct business at the facility. County leaders said they continue their non-cooperation policy ahead of Election Day. NBC Bay Area (Oct. 30, 2026)
Marin: the Marin Rapid Response Network told the Pacific Sun it has documented 18 Marin residents detained by ICE so far in October, more than its total of 17 for all of 2025; the Multicultural Center of Marin gave Telemundo 48 a similar count of 17. These are network tallies, not individually confirmed incidents, so they are not scored. Pacific Sun (Oct. 30, 2026) · Telemundo 48 (Oct. 30, 2026)
Alameda County: ACILEP told Bay City News that ICE has detained at least eight people in the county since Oct. 16, including a fifth Hayward detention and one in Union City on Wednesday, Oct. 28; two people were hospitalized. The Oct. 28 Hayward and Union City arrests have one outlet so far, so they are not scored yet. Bay City News via SFGATE (Oct. 29, 2026)
Concord: Telemundo 48 and Hecho en California report that federal agents apparently detained a 26-year-old San Pablo man near the Concord Avenue exit of Highway 242 on the morning of Oct. 28, based on video and his family's account. ICE has not confirmed it, so it is not scored. Telemundo 48 (Oct. 29, 2026) · Hecho en California (Oct. 29, 2026)
Activity also reached the Central Coast over the weekend of Oct. 24-25: the Santa Cruz County Sheriff's Office said federal agents came to its Main Jail to take a person into custody but left without detaining anyone, and the Monterey County Rapid Response Network said two people were detained in Seaside. Both counties are outside this tracker's Bay Area count. KSBW (Oct. 26, 2026) · NBC Bay Area (Oct. 25, 2026)
Alameda County's ACILEP rapid response program said it tracked at least 10 ICE arrests in the county in the 12 days before Oct. 26, the most in a two-week span in 10 months; most were at ICE check-ins, its managing attorney told the Daily Californian. The Daily Californian (Oct. 26, 2026)
Dozens of advocates held a "die-in" at Oakland's Eastmont Mall on Oct. 25, asking the property owner to bar ICE from using its Lot C parking area, which legal observers say agents have used since December 2025. DHS said ICE's presence in public parking lots is authorized under federal law. This is a protest, not a new enforcement incident, so it is not scored. ABC7 News (Oct. 25, 2026) · Bay Resistance (event listing)
Immigration attorneys and rapid response networks reported an uptick in Bay Area arrests in the week of Oct. 16-22, several involving force; Mission Local verified six arrests in one week. ICE confirmed three of them to KRON4. Hotlines described the Peninsula arrests as targeted, not sweeps. Mission Local (Oct. 2026) · KRON4 (Oct. 2026) · The Almanac (Oct. 22, 2026)
Bay Area rapid response networks said they had not seen a local surge like the Central Valley arrests reported this month. KQED (Oct. 2026) · Mission Local (Oct. 16, 2026)
"Operation Safe California," a reported 45-day statewide enforcement push, has been described only by unnamed sources to the Washington Examiner. DHS has not confirmed it. It is not counted here. NBC Bay Area (Oct. 9, 2026)
Marin: the Marin Rapid Response Network told KALW that ICE detained at least four people on county property in San Rafael after supervisors adopted a new ICE policy on Oct. 20 (one outside the county jail Oct. 20, one inside the Civic Center Oct. 21, two more Oct. 23). Only one outlet has reported these so far, so they are not counted in the score yet. KALW (Oct. 27, 2026)
Sonoma County: Mission Local and KRCB report that masked ICE officers drew guns and detained a Forestville resident in a Santa Rosa parking lot after first surrounding his girlfriend's car; a temporary restraining order was filed that evening and he was released the next morning. The exact date is not given in either report, so it is not added to the score. Mission Local (Oct. 2026) · KRCB / NorCal Public Media (Oct. 28, 2026)
