FDC Honolulu is a federal detention center located right next to Daniel K. Inouye International Airport on Oahu, Hawaii. It opened in 2001, with its first inmates arriving that July, and is housed in a distinctive twelve-story tower rather than the sprawling, low-rise layout typical of rural federal prisons. As an administrative-security facility, it's built to hold both men and women across every security classification, though its primary role is as a short-term holding site — mainly for people awaiting trial or sentencing in the U.S. District Court for Hawaii, as well as those serving brief sentences before transfer elsewhere in the federal system. Its rated capacity is around 695. Because Hawaii's federal caseload is relatively small and geographically isolated in the Pacific, FDC Honolulu plays an outsized role as essentially the only federal detention option in the islands, which means inmates from other Pacific jurisdictions can pass through as well. For families, the key things to know are that stays here tend to be transitional rather than long-term, and its downtown/airport-adjacent location makes it relatively accessible compared to more remote federal institutions.
