Thurston County criminal history records are held by the Superior Court Clerk, the District Court, and the Sheriff's Office, all based in Olympia. The Superior Court handles felony cases for the entire county, including residents of Olympia, Lacey, and Tumwater. The District Court covers misdemeanors and traffic matters. The Sheriff's Office maintains arrest logs and jail bookings for unincorporated areas. This guide covers each office, what records they maintain, how to request copies, and how to run a full statewide background check through the Washington State Patrol for any Thurston County subject.
Thurston County Overview
Thurston County Superior Court Criminal Records
The Thurston County Clerk of Superior Court is the primary keeper of felony criminal case records for the entire county. This covers charging documents, plea agreements, sentencing orders, and final judgment rolls for all felony cases filed in Thurston County. The office also holds civil cases over $100,000, family law matters, probate, guardianship, and juvenile records. All of these are public under Washington Court General Rule 31 unless a judge has ordered them sealed.
The courthouse is at 2000 Lakeridge Drive SW, Olympia, WA 98502. You can visit in person Monday through Friday during regular business hours to view records at a public access terminal or request copies. Copy fees follow the standard Washington schedule: non-certified copies are $0.50 per page, and certified copies cost $5.00 for the first page plus $1.00 for each additional page. Bring the full name of the party or the case number if you have it.
Recent case information is also available online. The Washington Courts Odyssey Portal gives free access to case summaries, party names, charges, hearing dates, and disposition data for Thurston County cases. Full documents are not posted online and must be ordered from the clerk's office.
Thurston County District Court Records
The Thurston County District Court handles misdemeanor and gross misdemeanor criminal cases, traffic infractions, and civil matters under $100,000. Cases such as first-offense DUI, shoplifting, simple assault, and minor in possession are filed here. These records are public and can be searched through the Odyssey Portal or accessed in person at the court.
The District Court operates at multiple locations in the county, including Olympia and Lacey. Court hours run Monday through Friday during standard business times. The court provides forms and self-help guidance for people who are handling their own cases without an attorney. For records not available online, you can visit in person or mail a written request with the relevant case information and applicable copy fees.
Note: Municipal courts in Olympia, Lacey, and Tumwater handle misdemeanor cases arising within those city limits. County District Court covers unincorporated Thurston County.
Thurston County Sheriff Arrest Records
The Thurston County Sheriff's Office provides law enforcement for the unincorporated parts of the county and operates the Thurston County Jail. The Records Division maintains arrest logs, incident reports, and jail booking information. These records are public under the Washington Public Records Act, Chapter 42.56 RCW, with standard exemptions for active investigation files that have not been closed.
Conviction records are available to the public. Non-conviction data, meaning arrests that did not result in a conviction and where the case is no longer active, is restricted under RCW 10.97. Under RCW 10.97.080, such records can only go to criminal justice agencies or to the person whose record it is. If your request turns up an arrest with no conviction, the agency will redact that portion before releasing anything.
The Thurston County Sheriff's Office is the main law enforcement agency for unincorporated county areas and operates the county jail.
For a comprehensive statewide criminal history check, the Sheriff's Office will direct you to the Washington State Patrol WATCH system.
Statewide Background Checks Through WSP WATCH
The most reliable way to get an official conviction record for a Thurston County resident is through the Washington State Patrol. The WATCH system (Washington Access to Criminal History) delivers results online right away for $11.00 per search. You pay by credit or debit card and get immediate results. WATCH pulls from a fingerprint-linked statewide database, so it is more accurate than a name-only search at any single county office.
Mail requests are also accepted. A name-based mail request costs $32.00. If you include a fingerprint card for a more precise match, the fee is $58.00. Mail processing takes about 7 to 10 business days. Since the WSP main office is located in Olympia at 106 11th Ave SW, Suite 1300, it is accessible to Thurston County residents who prefer to handle this in person. The in-person option is free for reviewing your own complete record, including non-conviction data, for up to thirty minutes. Bring a valid government-issued photo ID.
More details on the process are at the WSP Criminal History Records page.
Note: WATCH shows conviction records and pending arrests under one year old. Non-conviction data older than one year is not included in general public searches.
Thurston County Public Records Requests
For county agency records that are not court documents, use the Thurston County Public Records system. This covers Sheriff's Office incident reports, county department correspondence, and meeting records. Requests can be submitted online, by mail, or in person. Court records must be requested separately from the court clerks, not through the county's general public records process.
Under RCW 42.56.520, Thurston County must respond to any public records request within five business days. The response may provide the records, give a production timeline estimate, or deny the request with a specific statutory reason. You do not need to explain why you want the records, and the county cannot ask. Fees cover only actual reproduction costs, not staff time. Electronic delivery is preferred when available and usually costs less than paper copies.
Conviction vs. Non-Conviction Data
Washington's Criminal Records Privacy Act, RCW 10.97, governs what Thurston County agencies can release. Conviction records, meaning cases ending in a guilty plea, verdict, or other adverse disposition, are public under RCW 10.97.050. Anyone can request them.
Non-conviction data is restricted. Under RCW 10.97.030, this covers records from cases that did not result in a conviction and where the case is no longer active. These records can only go to criminal justice agencies, to the subject of the record, or to parties specifically authorized by law. If a report contains both conviction and non-conviction data, the agency must redact the non-conviction parts before releasing anything to the public.
If your record contains errors, you can file a Request for Modification of Record Form with the Washington State Patrol. If the challenge is substantiated, the Criminal History Records Section makes the correction. Rules for deleting old non-conviction records are covered under RCW 10.97.060, which requires no prior convictions and sets defined waiting periods.
DOC Inmate Search and Sex Offender Registry
If someone from Thurston County is currently incarcerated in a Washington state prison, you can find them through the Department of Corrections Incarcerated Search. The database shows name, DOC number, age, and current facility. For federal inmates, check the Federal Bureau of Prisons locator separately.
For registered sex offenders, the statewide registry is at WASPC Sex Offender Information. Class A sex offense convictions require lifetime registration. Class B offenses carry a fifteen-year registration period. Class C offenses require ten years. Offenders register in person at the Thurston County Sheriff's Office under RCW 9A.44.130.
Thurston County Auditor and Historical Records
The Thurston County Auditor Recording Division maintains recorded documents such as deeds, mortgages, and liens. While not directly related to criminal history, these records can be useful when researching a person's background in the county. The office is at 2000 Lakeridge Drive SW, Olympia, WA 98502. For older criminal court records that predate the Odyssey system, the Washington State Digital Archives may have archived Superior Court records from earlier periods. The MRSC Criminal History and Arrest Records guide is also useful if you are new to the process of requesting criminal history in Washington state.
