Federal Detention Center Honolulu — BOP facility holding ICE detainees, central Pacific hub
Overview
The Federal Detention Center Honolulu (FDC Honolulu) is a Bureau of Prisons facility that serves as the only significant ICE-holding site in Hawaii and the primary federal detention hub for the central Pacific. It normally holds federal pretrial detainees, sentenced inmates, and inmates in transit. In February 2025, FDC Honolulu became one of nine BOP facilities nationally designated to reserve space for ICE detainees under a BOP-DHS arrangement, in response to the second Trump administration’s enforcement surge and the resulting strain on mainland detention bed space.
Because Hawaii has a low federal crime rate, the 950-bed facility typically holds only ~350 people, leaving substantial spare capacity that ICE has filled.
Key Details
ICE Population Growth (2025)
- Avg daily ICE detainees Jan 2025: 15
- Avg daily ICE detainees end of Nov 2025: 81
- Booked into FDC for ICE through mid-Oct 2025: 218 (vs. 130 in all of 2024)
- Of those booked in 2025 (through mid-Oct): 121 detained for alleged immigration violations only, 66 with prior criminal convictions, 31 with pending criminal charges
Mainland Transfers INTO Hawaii
Beginning summer 2025, ICE began transferring detainees arrested on the mainland to FDC Honolulu to relieve crowding at mainland facilities — an unusual reverse-flow given Hawaii’s isolation. Hawaii Public Radio reported (Dec 2025) that ICE was sending immigrants from the continental U.S. to Hawaii with little explanation. The greater the distance from arrest location, the harder it is for detainees to access attorneys and family — a core due-process concern raised by local immigration lawyers facing unprecedented caseloads.
Separate ICE Wards (2026)
Following the “One Big Beautiful Bill” appropriation (over $1 billion to ICE/CBP), the facility created separate male and female wards specifically for ICE detainees, who had previously been mixed with the federal criminal population.
Conditions — Rep. Tokuda Oversight Visits
U.S. Rep. Jill Tokuda visited FDC Honolulu multiple times, most recently her fourth visit on April 10, 2026, speaking with detainees via a translator. Her account: cells are air-conditioned and individual, but there is no daylight — small windows with no outside view. She noted the majority of detainees had built lives in Hawaii prior to detention (alongside detainees transferred from the mainland from Europe, Asia, Central and South America).
Habeas Litigation
15 habeas corpus petitions challenging ICE detention were filed in the District of Hawaii between January 2025 and early 2026 — including the nationally-cited Rico-Tapia ruling (see county-fight: hawaii-federal-detention-center-habeas-fight). At least six writs have been granted.
Why It Matters
FDC Honolulu is a textbook case of the BOP-as-ICE-overflow model layered onto extreme geographic isolation. Detainees flown 2,500+ miles from the mainland — or arrested locally then bound for mainland deportation flights — face the worst attorney-access problem of any detention setting in the country. The facility’s spare capacity made it an attractive ICE pressure valve, turning a low-crime Pacific BOP center into an emerging habeas battleground.
