Floating Property Reappraisal - June through August 2016
All houseboats, boathouses, other floating property and moorages in Columbia County are in the process of being reappraised for the 2016-17 tax year. Columbia County staff appraisers will arrive in a marked county vehicle and will be wearing a blue-gray vest with the county logo in front and ASSESSOR clearly visible on the back. Contact will be made with property owners or tenants who are on site at the time of the inspection, however, there will not be an attempt to contact owners who are not on site unless it is determined that additional information is necessary to complete the appraisal. Most properties will be reappraised using data currently in our records combined with a limited exterior inspection to determine changes in inventory or condition. If you have any questions, please call or email our office using the contact information shown above.

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 Revised Statutes and Oregon Administrative Rules.
