The hard part is done. Certification and a passed home inspection mean the system has verified that his release plan is solid and approved. What comes next is administrative, and unfortunately administrative processes in the correctional system do not move on anyone's preferred timeline.
The honest range is a few weeks to a few months. There is no specific deadline that facilities are required to meet between approval and actual release, and that ambiguity is genuinely frustrating when you are this close. The paperwork has to move between the facility, the parole board or releasing authority, and the supervising parole office in your jurisdiction. Each handoff takes time and depends on staffing, caseloads, and how cleanly everything has been documented.
What can slow things down even at this late stage is any loose end in the paperwork, a form that needs a signature, a condition that needs clarification, or a scheduling backlog at the supervising office. None of those are reasons to panic, but they are reasons the timeline is not precise.
What you can do is stay reachable and responsive. If anyone from the parole office or the facility contacts you with questions about the home plan or release conditions, respond immediately. Delays caused by unanswered calls or unverified information are the easiest kind to prevent.
His case manager is the best source of a realistic estimate on timing given where things stand right now. A polite check-in call every week or two is reasonable at this stage and keeps you informed without creating friction.
You are close. Stay patient.
