House arrest may be accompanied by electronic monitoring (electronic house arrest), or a condition whereupon the suspect or offender is prohibited from leaving his or her designated residence except in the company of a specified person, sometimes called a surety.
A person subject to house arrest may be prohibited from leaving his/her stated residence except in the presence of one of his sureties.
On good behaviour for a stated period of time, some bail or conditional sentences replace house arrest with a final period of a curfew.
"Regular reporting at the direction of the supervisor, house arrest for the first 4 months subject to pre-approved exceptions, a curfew for the balance of the order, an abstinence condition throughout the order as a reminder that this is a jail sentence and 50 hours of community service work, to be completed by the end of the 5th month."
"... the distinction between house arrest and being placed under curfew. There is a significant difference. House arrest is an order that requires the offender to be, in effect, incarcerated in their own home, except for limited circumstances with the permission of the Court or the sentence supervisor.
"A curfew, on the other hand, gives the offender the freedom to move about in the community at their own discretion so long as they comply with the general conditions of their sentence and return to their residence for the hours of curfew, typically 9:00 p.m. to 7:00 a.m. when many citizens are in their homes in any event."
House arrest, when ordered on a pre-trial basis, is considered to be one of the most stringent of bail conditions.
In the vernacular of youth and in the context of the imposition of parental discipline, house arrest is often referrreed to as being grounded.
