King County, WA Privacy & Surveillance: Recording & Consent Laws (2026)

Washington State's Privacy Act (Chapter 9.73 RCW) establishes one of the nation's strictest recording consent requirements. RCW 9.73.030 makes it a crime to intercept or record a private conversation without the consent of all participants. This applies to: in-person conversations, telephone calls, and electronic communications. A 'private conversation' is any oral communication uttered by a person who has a reasonable expectation of privacy — this has been interpreted broadly by Washington courts. Even a conversation in a public place may be considered private if the speakers are taking steps to avoid being overheard. Consent must be obtained from all parties — not just one. This makes Washington one of approximately 11 states with all-party consent requirements. Key exceptions include: (1) police officers may record with one-party consent if they are investigating drug offenses, bribery, kidnapping, or similar serious crimes (RCW 9.73.090); (2) emergency 911 calls are recorded with implied consent; (3) recording is permitted when all parties have been informed that the conversation is being recorded. The practical impact for King County residents is significant: recording a phone call with a contractor, landlord, or neighbor requires informing them and obtaining consent. Dashcam audio that captures conversations inside your vehicle with passengers requires their consent. Even recording a public meeting where attendees have an expectation of privacy may trigger the statute. Recordings obtained in violation of RCW 9.73.030 are inadmissible in court (RCW 9.73.050).
