What We Do

The Assessor’s office is responsible for determining the value of all taxable real and personal property in the county on a fair and equitable basis, along with maintaining accurate and accessible property information, providing timely and accurate assessments for tax purposes, and a detailed parcel map showing all parcels within the County. Chelan County is now annually updating all properties according to market sales, and continues to do physical inspections of every property on a 4-year cycle. Washington State law requires property to be assessed at 100% of fair market value.

Your property taxes fund state and county services, including roads, transit, schools, libraries, parks, hospitals, fire and rescue, law enforcement, environmental and social services.  Information such as parcel numbers, ownership, tax code areas, and assessed valuations for all property within the county can be obtained on-line through the property search of the Assessor's web site, or by calling the assessor's office during business hours.
