Residential confinement, sometimes referred to as house arrest, is used by Parole and Probation as an alternative to incarceration. Residential confinement is available for parolees, probationers and inmates. Residential confinement may include an electronic ankle monitor and equipment to measure alcohol content in the person’s body. Costs for residential confinement vary depending on what type of monitoring is required by law, or by a judge or the Parole Board.
