OLEO may receive complaints from any complaining party, including members of the public or employees of the KCSO.

If you wish to file a complaint about an encounter with or the service received from a King County Sheriff's Office employee, you may do so in the following ways: 

  • Complete the online form  (the form cannot be saved online.  You can fill it online, but you will need to save and email it - - , or download and print it.)
  • By calling us at 206-263-8870, so we can write down your complaint
  • By visiting us in person at 401 Fifth Avenue, Room 131, Seattle, WA 98104, so we can write down your complaint

You may also contact the precinct directly and ask to speak to a supervisor. See precincts and jurisdiction.

Complaints received by OLEO are forwarded to the Internal Investigations Unit (IIU) of the King County Sheriff’s Office, for further review.  If a complaint is identified for investigation by IIU, OLEO independently reviews the completed internal investigation and certifies whether it was thorough and objective.

A complaint may be considered for mediation if the allegation could be resolved better through talking and listening rather than through a formal disciplinary process. 

More questions about the complaint process and what happens next?  See the Frequently Asked Questions (FAQ) page.
