Sammamish Inmate Population Search
Sammamish inmate population records are managed through King County's jail system, which processes all arrests made by the King County Sheriff's Office. The Sheriff's Office provides contract policing for Sammamish under a long-standing services agreement, meaning every Sammamish arrest feeds into the same county booking system used by the rest of unincorporated King County and several contract cities. You can search current and recent Sammamish inmate records through the King County Jail Information and Lookup System, which is available online at no cost and updates throughout the day as bookings occur.
Sammamish Jail Overview
Where Sammamish Arrests Are Processed
Sammamish is a city in eastern King County, incorporated in 1999 on the Sammamish Plateau. The city contracts with the King County Sheriff's Office for all law enforcement services. When a sheriff's deputy makes an arrest within Sammamish city limits, the person is transported to one of two King County correctional facilities for booking.
Most Sammamish arrests go to the King County Correctional Facility (KCCF) at 500 5th Ave in Seattle. This facility is the main downtown detention center operated by the King County Department of Adult and Juvenile Detention, or DAJD. For cases that come out of the southeast part of King County, some individuals may instead be processed at the Maleng Regional Justice Center (MRJC) at 401 4th Ave N in Kent. The type of charge and arresting circumstances typically determine which facility receives the person.
The King County DAJD oversees both facilities and maintains all booking records. The department also manages the public-facing jail lookup system, which is the main tool for searching Sammamish inmate population data.

The King County Sheriff's Office has provided contracted law enforcement to Sammamish since the city incorporated. Deputies who patrol Sammamish are part of the sheriff's Contract Cities Division. All use-of-force reports, arrest logs, and incident data generated in Sammamish flow through the sheriff's department rather than a city police department. That means records requests for Sammamish Police incidents go to the Sheriff's Office, not a municipal department.
How to Search Sammamish Inmate Population
The King County Jail Information and Lookup System (JILS) is the main tool for searching current Sammamish inmate population data. The system is free and available online at any time. You do not need an account or login to run a search.
To find someone in the Sammamish inmate population, go to the King County JILS lookup at dajd-jms.powerappsportals.us. Last name is a required field. You can also add first name, middle initial, date of birth, race, and gender to narrow results. The system also accepts booking number if you have it. Results show the full name, booking number (called a BA number), the facility where the person is held, booking date, expected release date, charges, bail amount, housing unit, and upcoming court date.
The DAJD also maintains a jail register that shows everyone currently in custody plus people who were booked or released in the past 24 hours. This register is updated throughout the day. You can search records up to 365 days back using JILS, which is useful for recent releases. The King County DAJD page below shows the agency that manages all Sammamish inmate population records and the tools it provides to the public.
The DAJD page links directly to the JILS lookup tool and provides additional guidance on how to contact the facility, request visitation, and submit public records requests for booking data.
Note: If someone does not appear in JILS, they may have been released, transferred to a state DOC facility, or held in a different county. Try the Washington State DOC search if the person was convicted of a felony.
Public Records Access for Sammamish Inmate Data
Washington's Public Records Act under RCW 42.56 gives every person the right to request government records without explaining why. That includes booking logs, arrest reports, jail intake records, and custody status information. Agencies must respond within five business days. The response can be a full release, a partial release with explanations, a timeline for completion, or a request to clarify what you are looking for.
Jail registers specifically are covered by RCW 70.48.100, which requires all county jails to keep a public record showing each person's name, the date and time they were confined, and how they were released. The JILS system and DAJD daily register both exist in part to meet this requirement. When you search the online roster, you are looking at data the county must keep public under state law.
To request Sammamish-related police records, contact the King County Sheriff's Office. For records held at KCCF or MRJC, contact the DAJD at kingcounty.gov/dept/dajd.aspx or visit their public records office at 516 Third Ave, Room W-116, Seattle, WA 98104. The main public records line is 206-296-4155. Written requests are preferred for anything beyond basic roster data, and you can submit requests by mail, in person, or through the county's online public records portal.
Some records may be withheld if they are part of an active investigation or if release would violate a third party's privacy rights. But basic arrest and booking information is almost always releasable under the public records law.
VINE Notification for Sammamish Inmates
VINE (Victim Information and Notification Everyday) lets you track custody status changes for an inmate held at a King County jail facility. If a Sammamish inmate is released, transferred, or has a court date come up, you will get an alert by phone, text, or email. You can sign up at VINELink.com. Registration is free and you do not have to give your name.
The service is run by the Washington Association of Sheriffs and Police Chiefs and covers jail facilities across the state. For Sammamish arrests, VINE works with both the KCCF in Seattle and the MRJC in Kent. The system checks custody status approximately every 15 minutes, so you will usually get a timely notification when something changes. You can monitor more than one person at a time using a single account.
VINE also covers state prison inmates at Washington DOC facilities. If a Sammamish resident was sentenced to state prison after a felony conviction, you can set up VINE notifications for their DOC record as well. This makes it a useful single-stop tool for tracking both pre-trial and post-conviction custody across different levels of the system.
State Resources for Sammamish Inmate Searches
When a Sammamish resident is convicted of a felony and given a sentence longer than one year, they serve that time in a Washington State Department of Corrections facility rather than King County jail. The Washington State DOC incarcerated person search at doc.wa.gov covers all state prisons, work release centers, and reentry programs. You can search by name or DOC number, and results show the current facility, sentence details, and projected release date.
The Washington State Patrol WATCH system at watch.wsp.wa.gov runs criminal history searches for $11 per lookup. The system is fingerprint-based, so it gives more accurate results than a name search alone. It covers convictions statewide and arrests less than one year old that have a pending disposition. For a thorough background check on someone from Sammamish, WATCH gives the most complete view available to members of the public.
Court records for Sammamish cases are available through the Washington Courts public case search at courts.wa.gov. Misdemeanor cases are handled in King County District Court. Felony cases go to King County Superior Court. Case search results show charges, hearing dates, dispositions, and sentencing information. Keep in mind that arrest records and court records are separate systems, and someone who was arrested may have had their case dismissed or reduced later.
