Summary

King County treats license-plate-reader data as personal information and bars county agencies and contractors from handing it to ICE, CBP, or USCIS for civil immigration enforcement without a judge's warrant.

City-specific rules exist: Seattle has its own license plate readers rules that differ from King County's county-level regulations. If you live in Seattle, check the city-specific page instead.

Provide personal information to federal immigration authorities for purpose of civil immigration enforcement, except as required by state or federal law, about any person, including place of birth or household members, the services received by the person or the person's next court date or release date, absent a warrant signed by a judge or a law requiring disclosure.

Full Breakdown

King County Code chapter 2.15 defines 'personal information' to include any data collected through an automated license plate recognition system (K.C.C. 2.15.005.S.10). County agencies, employees, and contractors are barred from handing that data to ICE, CBP, USCIS or any other federal agency for civil immigration enforcement -- covering a person's location, court dates, or release date -- unless a judge signs a warrant or another law compels disclosure (K.C.C. 2.15.020.B.5). The code sets no separate ALPR retention period or council-approval process here; it only regulates ICE/CBP/USCIS data sharing.

Violations & Fines

Anyone harmed by a violation may file a damages complaint with the King County Office of Equity and Racial and Social Justice under K.C.C. 2.15.100 and 12.22.040; the chapter sets no fixed fine schedule.

Frequently Asked Questions

Does King County Code set retention limits for license-plate-reader data?
No. Chapter 2.15 only bars sharing ALPR-linked personal information with federal immigration agencies without a warrant; it does not set a retention period or require council approval of ALPR/Flock cameras.
Does this rule cover Seattle Police Department's license-plate readers?
No. Seattle, Bellevue, Kent, Renton, and other cities have their own municipal codes; King County Code chapter 2.15 governs county agencies and contractors, not city police departments.
