Manufactured Structures

Manufactured structure ownership and siting information is maintained by the Building Codes Division (BCD) of the Oregon Department of Consumer and Business Services (DCBS). 

As of  May 1, 2017, the Columbia County Assessor's Office will again be able to process  applications for manufactured home ownership or situs changes.  The cost for ownership and situs changes is $55 per application.  The cost for trip permits is $5 per section. We will continue to provide certification that taxes have been paid for those who choose to process the change online though the Building Codes Division (BCD) of the Oregon Department of Business and Consumer Services (DCBS) website.  Please visit for more information.

For changes requested after July 1 and prior to tax certification for the current tax year, an estimated tax for the current tax year will be collected.

CERTIFICATE OF TAXES PAID ON MANUFACTURED STRUCTURE can be downloaded here, and you may bring or mail the form to our office or email to for completion.

Additional forms can be downloaded from BCD.
