Somerset County Jail Role
Somerset County Jail is operated by the Somerset County Sheriff's Office and remains the county jail facility at 40 Grove Street in Somerville. The current public role is narrower than the old one-county-one-jail model. Somerset County says the jail continues to meet court and local law-enforcement needs on a limited basis, including short-term housing for detainees scheduled for court hearings. It is also the point associated with processing, intake, custody records, and transport when someone enters the Somerset County jail system.
The most important Somerset County Jail inmate lookup fact is that the jail no longer serves as the county's overnight adult housing facility. The Somerset County visitation notice says incarcerated persons are processed into Somerset County Jail and transferred to Morris County Jail, and that the Somerset jail does not house incarcerated persons overnight after the October 22, 2024 change. That makes the custody path split: recent arrest and court-hearing questions start in Somerville, while longer county-jail housing questions usually move to Morris County Correctional Facility.
Somerset County Jail Population
The current Somerset County Jail population figure is best described as an operational status, not a daily roster count. Somerset County reports no overnight housing at the Somerville jail after October 22, 2024. Morris County's June 18, 2024 shared-services release states that nearly 80 Somerset County inmates moved to Morris County Correctional Facility from June 3 through June 6, 2024, under an agreement that continues until May 2029. Those people remain Somerset County detainees by case origin, but the adult jail bed is in Morristown.
| Custody stage | Where to check | Reason |
|---|---|---|
| Fresh Somerset County arrest | Somerset County Jail | Processing and short-term court custody may still occur in Somerville. |
| Overnight or longer county custody | Morris County Correctional Facility | Somerset detainees are transferred there under the current agreement. |
| State-prison sentence | NJDOC Offender Search | State-sentenced prisoners leave county jail custody. |
Look Up Somerset County Jail Custody
No official public Somerset County Jail online roster was located in the county sources. That does not mean custody cannot be checked. It means the Somerset County Jail inmate search is a phone, records, VINE, court, and OPRA workflow rather than a public name-search roster. For a very recent arrest, call the Somerset jail information line first. If the person is held overnight or beyond a brief court-hearing window, call Morris County Correctional Facility Records because Somerset's current adult detainees are housed there for longer stays.
- Call Somerset County Jail for a new arrest, intake, or short court-hold question.
- Call Morris County Correctional Facility Records if the person may have been transferred after processing.
- Use New Jersey VINE for custody status and victim notification when available.
- Use New Jersey Courts case search for charges, court dates, complaint numbers, and case posture.
- File a Somerset County OPRA request for specific booking, intake, transfer, or release records not available by phone.
A person may be physically housed in Morris County while the case remains a Somerset County matter. Use that wording when asking for records: "Somerset County detainee housed at Morris County Correctional Facility."

Somerset County Jail Visits
Somerset County Jail visitation is limited by the facility's current role. Because Somerset does not house people overnight, routine adult jail visiting for longer-term Somerset detainees follows Morris County rules after transfer. For a person held briefly in Somerville for a court hearing, call the jail before traveling. Do not assume a visit can be arranged at 40 Grove Street just because the case began in Somerset County.
| Situation | Visit channel | What to confirm |
|---|---|---|
| Short-term court custody in Somerville | Call Somerset County Jail | Whether any visit is allowed before transport or hearing. |
| Somerset detainee housed overnight | Use Morris County visitation rules | Floor, classification, day, registration window, and ID rules. |
| State prison transfer | Use NJDOC facility visitation | Approval, scheduling, and the specific state facility. |
Note: Confirm the physical custody location before any visit because Somerset County detainees may move quickly after processing.
Somerset County Jail Mail and Money
Somerset County's mail and account information points users to Morris County for people housed longer than the short Somerset processing or court-hearing stage. Mail, phone calls, commissary deposits, and personal-property rules are controlled by the facility where the person is physically housed. For Morris County housing, the mail format is Morris County Correctional Facility, Attn: inmate name, 43 John Street, Morristown, NJ 07960.
| Service | Somerset County Jail record path |
|---|---|
| Call first for a short Somerville hold; use Morris mail rules after transfer. | |
| Phone calls | Morris County uses outgoing inmate calls through AdvancePay for housed detainees. |
| Money deposits | Morris County accepts money order routes and Access Corrections options for housed detainees. |
| Records | Use Somerset OPRA for specific booking, transfer, commitment, or release records. |
Somerset County Jail Booking
Booking at Somerset County Jail can include identification, property handling, an initial custody record, medical or security screening, and coordination with the court process. The Somerset Corrections Division also describes Medication Assisted Treatment screening when an inmate self-discloses alcohol or opioid use disorder or tests positive for opioid use. Qualified people may receive medication options, counseling, education, and release transition support.
The arrest-to-custody chain in Somerset County is not complete until the housing location is known. A complaint-warrant case can bring a person into custody and a first court appearance. If the person remains detained, transfer to Morris County is the normal longer-stay path. A complaint-summons case may not involve jail detention in the same way. For charges and court records, use the Judiciary system rather than relying on jail staff to explain the formal case.
- Remand
- A court order placing a person in custody.
- Transfer record
- A custody record that helps show movement from Somerset processing to Morris housing.
- Classification
- The jail process used to assign housing and supervision level after intake.
About Somerset County Jail
The Somerset County Jail remains part of the Sheriff's public-safety system even after the overnight housing change. The Sheriff's Office handles jail operation, prisoner transportation, courthouse security, warrants, civil process, criminal identification, K-9, gang intelligence, and related county law-enforcement work. Jail administration sources also describe social services, drug and alcohol counseling, religious services, education, work release, control-center technology, and added camera monitoring.
Recent reform is central to any Somerset County Jail roster question. Sheriff Darrin J. Russo's county bio describes the jail transition as a detention-hub model tied to declining incarceration trends and shared services with Morris County. Morris County's release says the shared-services agreement was designed to cut operating costs while giving Somerset detainees access to programs, reentry services, Hope Wing addiction recovery, and vocational or education support at Morris County Correctional Facility.
Note: Call the facility before travel because custody, visits, mail, and money rules depend on the current housing location.
