Federal home confinement is a program that allows certain inmates to serve a portion of their sentence in their homes. Typically, these inmates are transferred to an approved home address within the last 12 to 18 months of their sentence. Some inmates might also qualify for home confinement after their arrest while they are awaiting trial. During home confinement, their movements are closely monitored by an ankle GPS monitor. While they might be allowed to access certain outdoor portions of their home, they are mostly confined to the interior structure of the house. They may live with other family members in the home, but they must meet the requirements of the program. There can be no history of violence, and the address must be approved by US Probation or the Federal Bureau of Prisons.
