Understanding Property Tax

The Washington State Department of Revenue has created an Understanding Property Tax video to help explain the basics.
Assessed Value vs. Property Tax

Property Inspections

Properties with new construction are physically inspected in all areas of the county. Appraisers will be driving clearly marked white county vehicles and wearing county-issued badges. If they need to step foot on the property, they will knock on the door to introduce themselves. If no one is home, they will leave a door hanger to indicate they visited. During the inspection, appraisers will measure and photograph the exterior of buildings and decks as required. Afterward, staff may remain in their vehicles to update property records.
