Fox Valley Adult Transition Center Overview
Fox Valley Adult Transition Center is operated by the Illinois Department of Corrections. The state classifies it as an adult transition center with transitional security, which is a step down from a standard prison. State materials say it houses female individuals in custody and works as a community-transition or work-release style placement. People here are generally sentenced state-custody individuals preparing to return to the community, not recent arrestees waiting for a first court date.
This difference matters for any search. A Kane County resident sentenced from the county courthouse may pass through the county jail first, but once in state custody they show up in the statewide locator. The county detainee search will not reliably cover someone after transfer to the state system, so Fox Valley should never be treated as a county jail.
The center's role also shapes who is there at all. As a transition center, it tends to hold women who are further along in a sentence and closer to release, rather than people at the start of a long prison term. That makes it a reentry placement within the state system, and it explains why the population stays small compared with a full prison.
Fox Valley Adult Transition Center Capacity and Population
The state lists Fox Valley with an operational capacity of 128 and a population of 117 as of June 30, 2024. These are state corrections figures for this one facility, and they should not be mixed with the much larger county jail capacity. The center is the only state corrections facility found physically inside Kane County during this research.
No standard state prison or reception center sits in Kane County beyond this transition center.
How to Look Up an Inmate at Fox Valley
The right tool is the statewide corrections locator, not the county roster. The Illinois Department of Corrections inmate search covers people in state custody and asks how you want to search before showing results.
- Open the state corrections inmate search.
- Search by last name, by the state IDOC number, or by birthdate.
- Confirm the parent institution or location reads Fox Valley Adult Transition Center.
- Open the profile for status, sentence, admission date, and parole or discharge projections.
A state profile shows different fields than a county jail record. Instead of bail and a next county court date, it lists the offense class, the sentence length, the admission date, the mittimus or case number, and projected parole and discharge dates. The state notes that this information can change quickly.
What a State Inmate Record Shows
A state corrections profile is built around the sentence, not the booking. That is the clearest sign you are in the right system: a county jail record talks about bail and the next hearing, while a state record talks about admission, sentence, and release projections. The fields below are the ones a state profile typically carries.
| Field | What It Shows |
|---|---|
| IDOC Number and Name | The state custody identifier and the person's name. |
| Parent Institution / Location | The assigned facility, such as Fox Valley Adult Transition Center. |
| Offender Status | The current state custody status. |
| Admission Date | When the person entered state custody. |
| Offense and Sentence | The offense class, count, sentence length, and county of conviction. |
| Parole / Discharge Dates | Projected parole and discharge dates. |
The state directs written correspondence about a record to its public information office, and it warns that statuses and dates can shift, so a projection is an estimate rather than a fixed release day.
Fox Valley Adult Transition Center Address and Contact
The center is in Aurora, on the west side of the county. Because it is a state facility, custody and case questions route through the state corrections system rather than the Kane County Sheriff's Office.

Visiting Someone at Fox Valley
State facilities do not use the county jail's video-visit kiosk system. State corrections visitation generally requires an approved visitor list and scheduling, with facility-specific days and hours set by the department. Because the county sheriff does not control these rules, the safest move is to use the state facility page and the state family-and-friends resources, then confirm current visiting days directly with the center.
The table shows how a Fox Valley lookup and visit differ from the county jail.
| Fox Valley (State) | County Jail | |
|---|---|---|
| Run By | Illinois Department of Corrections | Kane County Sheriff's Office |
| Look Up With | State corrections locator | County detainee search |
| Visiting | Approved list and scheduling | JailATM video slots |
| Who Is Held | Sentenced women in transition | Pre-trial and short sentences |
Mail and Money at Fox Valley
Mail, deposit, and phone rules at Fox Valley are set by the state corrections department, not the county. The county jail's mail-scanning address in Arkansas and its JailATM and TouchPay vendors apply to the Adult Justice Center, not to this state facility. For correct mailing instructions and the approved money and phone vendors, use the state facility page and family-and-friends guidance, and confirm before sending anything.
Written correspondence about a state inmate's record can also go to the state corrections public information office, which the locator lists. Do not reuse county jail vendor details for this facility, since the wrong address or vendor can delay or reject what you send. The state sets its own approved-sender rules, package limits, and money-deposit vendor, and those can differ from the county jail's setup, so the safest step is to read the current facility page before mailing or depositing anything.
Admission and Transfer to Fox Valley
People do not arrive here straight off the street. The path runs through arrest, the county jail, the court, and a prison sentence, after which the state may place a woman in a transition center as she nears release. That makes Fox Valley a reentry step rather than an intake point. Someone who began in the Kane County Adult Justice Center and was sentenced to state time can end up here on the way back to the community.
Because the placement happens deep in the process, the county roster is rarely the right tool by the time a person reaches Fox Valley. By then the case has a disposition, a sentence, and a state custody record, and the state locator is where all of that lives.
Custody Alerts for Fox Valley
Victims and family members who want to know when a person's custody changes do not have to check the locator by hand. Illinois runs a free notification service that connects to state corrections, county jail booking systems, and the circuit clerks. A registered user can get alerts by email, text, phone, or mobile app when a status changes.
This is often more reliable than manual checks for a transition center, where a move toward release can happen on short notice. The state victim notification line listed in official materials is 1-866-566-8439. Registration is free and does not require any relationship to the case beyond an interest in the alert.
About Fox Valley Adult Transition Center
A transition center exists to bridge prison and release. Residents often work, attend programs, or take part in community activities under supervision while finishing a sentence. Because it serves women in transitional custody, its day-to-day routine differs from both a county jail and a higher-security prison. For victims and families who want custody-change alerts, Illinois VINE registers notifications for state and county custody, which can be more reliable than checking the locator by hand. For the county custody side of a case, the jail inmate records page covers the sheriff's roster.
Note: confirm custody, visiting days, and mailing rules with the state facility before traveling or sending anything, because state placements and schedules change.
