Criminal Cases in the Washington County Circuit Court
In Oregon the public criminal record is the court file. Criminal cases from Hillsboro are heard by the Washington County Circuit Court, which hears every civil, criminal, family, probate and juvenile case, and the file of each case is kept by the trial court administrator.

The Oregon Criminal History and Your Own Copy
Oregon is one of the states that lets anyone look up another person's statewide criminal history: an Open Record Request returns anyone's Oregon conviction record by name, and the subject is told who asked, for $10 a search, through the Oregon State Police. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Oregon State Police site.
Arrest Records Kept Locally in Hillsboro
The Washington County Sheriff's Office and the agency that reports for Hillsboro (filed by the FBI as Hillsboro Police Department) keep the arrest records in and around Hillsboro: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places these agencies in Washington County: the Washington County Liquor Commission (state agency); the Hillsboro School District (other agency); the Washington County State Police (state police); each keeps the records of its own arrests.
The Portland Police Department and the Lake Oswego Police Department are each listed by the FBI across several counties including Washington County, so their arrests are not broken out for Washington County here.
Together, the 12 agencies in Washington County with all twelve months of 2025 on file reported 18,060 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Hillsboro arrest records.
The Crimes Behind the Records: Hillsboro in 2025
The agency that reports for Hillsboro had 320 violent and 2,201 property crimes reported for 2025; each one is a report on file with it, and each arrest that follows is the start of a criminal record.

The Sex Offender Registry for Hillsboro
Registered sex offenders living in Hillsboro are listed on the Oregon Sex Offender Registry, run by the Oregon State Police. Only Level 3 and some Level 2 registrants are listed online.
Registration itself is done in person with the local agency where the registrant lives: the sheriff's office, or the city police in a city with its own department.
Asking an Agency in Washington County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Oregon Public Records Law a county office must answer a request within 15 business days where practicable, after acknowledging the request within 5, and it may charge the actual cost of making the record available.
