The advertisements on the King County Assessor’s eReal Property website are part of a pilot program to test the viability of web ads on the site. The goal of the ads is to generate revenue to support department operations and taxpayer services. Advertisements are placed in accordance with the Department of Assessments’ guidelines for web advertising.

An important part of our work is to gather public feedback and to make sure the advertising does not interfere with the viewing or navigation of the Assessor’s website. If you have any questions or comments, we encourage you to send them to: We want to hear from you.
