Mission Statement

The mission of the Columbia County Assessor's Office is to apportion the cost of supporting local public service districts, on behalf of the patrons of those districts, so no taxpayer is required to pay more or less than their fair share by annually producing an accurate and timely assessment roll that complies with Oregon statutes and Department of Revenue rules.
