Maleng Regional Justice Center Overview
Maleng Regional Justice Center, usually called MRJC, is a full King County adult secure detention facility in Kent. It is not an annex of the Seattle jail and it is not the City of Kent Corrections Facility. King County opened MRJC in 1997 and uses it as a regional courthouse and jail complex for south county custody. It is operated by the Department of Adult and Juvenile Detention, the same agency that operates King County Correctional Facility in Seattle.
MRJC holds adults in King County custody, including people awaiting hearings, people booked on felony and misdemeanor cases, people serving local jail sentences, and people held for court orders. The facility's location in Kent makes it easy to confuse with the city jail at 1230 Central Ave. S. That is a separate municipal facility with a separate Kent lookup system. If the person is booked into King County DAJD, the correct search path is the King County Subject Lookup Tool and the adult jail phone line.
The county's official adult jails page lists MRJC with KCCF and provides the shared adult jail information line. The King County adult jails source is the matching manifest source for the adult jail image below.
The shared county page helps distinguish DAJD's two adult jails from nearby municipal and regional jails that use different lookup systems.
Maleng Regional Justice Center Population
King County's captured facility pages do not publish a rated-bed count for MRJC. The official DAJD scorecards publish Average Daily Population by adult jail location, so those figures are the best sourced numbers for this page. The 2025 annual DAJD scorecard lists MRJC adult secure ADP at 621.2. The 2026 scorecard through May lists MRJC ADP at 596.6. These numbers should be read as custody averages, not as the number of people held on any single hour of a given day.
| Measure | Figure | Source |
|---|---|---|
| MRJC adult secure ADP | 621.2 | DAJD 2025 Detention and Alternatives Report |
| MRJC adult secure ADP | 596.6 | DAJD 2026 through May scorecard |
| Adult secure ADP, KCCF and MRJC | 1,411.5 | DAJD 2025 report |
Maleng Regional Justice Center Roster
MRJC custody is searched through the King County Subject Lookup Tool. The tool is a custody and booking search, not a complete court record and not proof of conviction. It can show whether an adult is currently in custody, where the person is held, and the booking or B/A number. That number is needed for jail contact, deposits, mail, and health-concern calls. The same search can also help with a recent King County jail stay because DAJD says the tool allows searches for people who have been at King County jails during the last year.
- Search by last name first, then add first name and DOB if needed.
- Select Currently In Custody = Yes for active MRJC custody.
- Use Facility = Maleng Regional Justice Center only when the location is known.
- Write down the B/A number, facility location, custody status, and bail information if shown.
- Call 206-296-1234 if the person is not found and the arrest appears to be a King County adult jail matter.
When the lookup fails, the fallback chain matters. King County itself tells users to check other regional jails and prisons in some cases. A person arrested in Kent might be at the City of Kent Corrections Facility, SCORE, MRJC, or another system, depending on the charge, warrant, booking agency, and court. Sentenced state prisoners are searched through the Washington DOC locator, and federal custody is searched through the BOP locator.
| System | When to Use It | Why It Matters |
|---|---|---|
| King County Subject Lookup | Adults held at MRJC or KCCF | DAJD custody and recent jail stays. |
| Kent JILS | Kent municipal arrests and warrants | Separate city jail, not MRJC. |
| SCORE | South county municipal jail custody | Separate regional jail in Des Moines. |
| Washington DOC | Sentenced state prison custody | Used after transfer from county jail. |
Maleng Regional Justice Center Contact
MRJC's official address is 620 W. James St. in Kent. King County uses the same public adult jail phone number for MRJC and KCCF. The adult jail line is the practical first call for custody status, visit questions, and general jail information when the online lookup does not answer the question. Records requests for incarceration records or jail operations records go through DAJD records, not the courthouse counter.

Maleng Regional Justice Center Directions
King County publishes more detailed driving directions for MRJC than many jail pages do. From downtown Seattle, the county route uses I-5 southbound to the Kent/Des Moines exit, then Highway 516 to Fourth Avenue, then James Street. From Highway 167, the county route uses Willis Street east to Fourth Avenue, then about one mile north to James Street. The adult jails page notes that drivers enter the parking garage after turning from James Street, which is a useful local detail for visitors who have not been to the Kent complex before.
Visitors should still confirm parking, entrance rules, court dates, and custody location before travel. MRJC is a jail and courthouse complex, and a hearing at the Kent courthouse does not always mean the person is still housed there. Search the roster first, then call the adult jail line if the facility field is unclear.
Maleng Regional Justice Center Visits
MRJC uses King County adult jail visiting rules. Schedules and housing-based times are facility-specific, so the safest source is the current MRJC schedule or the adult jail information line. Visitors need government-issued picture identification and must follow clothing rules. King County bars miniskirts, revealing necklines, bare midriffs, exposed undergarments, and other clothing that violates the posted dress code. Visits may be refused when a visitor is late, lacks ID, or does not meet the rules.
| Visit Item | MRJC Rule | Where to Confirm |
|---|---|---|
| In-person schedule | Facility and housing-location specific | King County adult visit page or 206-296-1234 |
| Visitor ID | Government-issued picture ID required | DAJD visitor rules |
| Video visits | Up to six free video visits per week | Securus Video Connect instructions |
| Monitoring | Public video visits are recorded and monitored | DAJD video visit rules |
Maleng Regional Justice Center Mail Money
MRJC uses the same adult jail mail, phone, video, and money systems as KCCF. Ordinary personal mail goes to the Securus Digital Mail Center in Tampa, not directly to Kent. The envelope must include the person's first and last name and the 10-digit booking number. If the full number is missing, King County says the mail will be returned. Legal mail and publications go directly to MRJC at 620 W. James St. with the full booked name and B/A number.
| Service | MRJC Detail | Rule |
|---|---|---|
| Personal mail | Full name and booking number, C/O Securus Digital Mail Center-King County, P.O. Box 20245, Tampa, FL 33622 | USPS only; white paper and envelope rules apply. |
| Legal mail | Full booked name and B/A number, 620 W. James St., Kent, WA 98032 | Sent directly to MRJC. |
| Phone calls | Securus | Two free calls weekly, then 5 cents per minute. |
| Deposits | Access Corrections | Online, app, lobby kiosk, phone, retail cash, or mailed cashier's check/money order. |
| Bail | MRJC reception window | 7 a.m. to 10 p.m., seven days a week. |
The King County adult jail mail page is the source for the digital mail center address and MRJC legal-mail path.
The scanned-mail system makes the B/A number more than a roster detail; without it, mail and account actions can fail.
Maleng Regional Justice Center Programs
King County adult jail residents may have access to medical care, behavioral health care, personal development, education, religious services, recreation, drug and alcohol counseling, and release planning. Program availability can change based on staff, volunteers, housing, classification, and contractors. Most residents receive a tablet after housing assignment unless access is limited for discipline, and educational materials may be available through tablet programs.
Health concerns should go to Jail Health Services with enough identifying information to match the person. Family members can call 206-296-1091 or email JHSRequests@kingcounty.gov. Include the person's full name, B/A number, the caller's contact information, and the medical or behavioral health concern. Do not use the public roster as a medical source; it is a custody lookup, not a health record.
Note: Confirm MRJC custody and visiting status before travel because court movement or housing changes can affect visits.
