Privacy & Surveillance in Seattle, WA: What Residents Actually Need to Know

If you live in Seattle or are thinking about moving there, privacy & surveillance are one of those things you probably won't think about until they affect you directly. Seattle has 5 specific rules on the books covering different aspects of privacy & surveillance, and some of them might surprise you.

Facial Recognition Ban

Seattle SMC 14.18 (2017, expanded 2018) makes Seattle one of the first US cities to require City Council approval and a Surveillance Impact Report before any city department acquires or deploys surveillance technology, including facial recognition.

Key details: Code: SMC 14.18. Adopted: 2017. Approval body: City Council. Review document: Surveillance Impact Report. SPD facial rec: Not approved.

Department use of unapproved surveillance tech: violation of SMC 14.18 subject to enforcement by City Auditor. Officers must cease use; data may be ordered destroyed. Council can withhold funding.

This is one of the stricter rules in Seattle's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

License Plate Readers

Seattle Police use of automated license plate readers (ALPRs) is governed by SMC 14.18 surveillance rules. SPD's ALPR program required a Surveillance Impact Report, City Council approval, and is bound by data-retention limits.

Key details: Authority: SMC 14.18 + SPD 16.170. Retention (no hit): 90 days. ICE sharing: Prohibited. SIR approval: City Council. State law: RCW 43.17.425.

Officer misuse: discipline up to termination plus criminal charges if accessed for personal reasons (RCW 9A.56.020 computer trespass). Department breaches of SMC 14.18: Council enforcement, possible defunding.

This is not one of those rules that cities tend to ignore. Seattle actively enforces its license plate readers requirements.

Security Camera Rules

Seattle allows residential security cameras on private property but Washington's strict two-party consent law (RCW 9.73.030) applies to audio recording. Video-only recording of public areas is generally permitted. Cameras must not record areas where people have a reasonable expectation of privacy.

Key details: Audio Consent: All-party consent required (RCW 9.73.030). Video Only: Permitted for public-facing areas. Permit Required: No permit for residential cameras. Privacy: Cannot record areas with privacy expectation.

Illegal audio recording: gross misdemeanor under RCW 9.73.030. Civil liability for invasion of privacy. Illegally recorded conversations are inadmissible in court.

Washington is a two-party (all-party) consent state under RCW 9.73.030. Recording any private conversation without consent from all parties is a gross misdemeanor. This applies to phone calls, in-person conversations, and audio features on security cameras.

Key details: Consent Type: Two-party (all-party) consent. Statute: RCW 9.73.030. Criminal Penalty: Up to 364 days jail, $5,000 fine. Civil Liability: Yes, damages available.

Gross misdemeanor: up to 364 days in jail and $5,000 fine. Civil liability for damages. Evidence inadmissible in court.

This is not one of those rules that cities tend to ignore. Seattle actively enforces its recording & consent laws requirements.

Privacy Screening

Seattle allows privacy fences up to 6 feet in residential zones without a building permit. Fences up to 8 feet (with architectural features like trellises) may be permitted. No permit is needed for fences 8 feet or shorter that are not masonry or concrete above 6 feet.

Key details: Max Height (Side/Rear): 6 feet (plus 2 feet trellis). Max Height (Front): 4 feet. Permit Required: No (if 8 feet or less, non-masonry). Barbed Wire: Prohibited in residential zones.

Fences exceeding height limits or in restricted areas may receive a Notice of Violation from SDCI. No permit required for most residential fences.

The rules around privacy screening in Seattle lean permissive, but that does not mean anything goes.

If you are a homeowner, renter, or business owner in Seattle, take the time to understand these requirements before they become a problem.
