The primary function of the Pretrial Supervision Unit is to enforce stipulations ordered by a judicial authority as it relates to pretrial release conditions. Once released, defendants are instructed to report by phone, report in person, or be placed and supervised under electronic monitoring. All conditions ordered and enforced, are to ensure that the defendant appears at all scheduled court hearings until final case disposition, and to manage the risk of re-arrest to the community.

All pretrial supervision stipulations are enforced and supervised by Pretrial Officers with the exception of the Pretrial Electronic Monitoring stipulated cases. These cases are coordinated by Pretrial Officers, but supervised by the Allegheny County Adult Probation Electronic Monitoring Unit.

If supervision conditions are ordered, and upon release from the Allegheny County Jail, a defendant must comply with the level of supervision ordered by either phoning into the designated phone number or reporting at 10:00am on the day after release from the jail. Failure to comply with court ordered conditions may result in incarceration or bond revocation. The Pretrial Electronic Monitoring conditions require all other "holds" be satisfied prior to being interviewed. Once all the information is verified the case is processed.
