The role of the Assessor is to estimate (appraise or assess) the value of all taxable property. It is our mission to serve the citizens of Cowlitz County by achieving accuracy, equity, and fairness in the estimation of value.

It is our responsibility to: 1) Neither underestimate nor overestimate the value of property; 2) See that all properties are assessed in a similar manner; 3) Ensure that each owner’s share of the total property tax is the same as his or her share of the total value of property.
