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 January 27, 2017, the Columbia County Assessor's Office is no longer authorized to process applications for manufactured home ownership or situs changes, however, we will provide certification that taxes have been paid.  The Building Codes Division (BCD) of the Oregon Department of Business and Consumer Services (DCBS) has launched their new online software system, and will be responsible for processing applications.  Please visit mhods.oregon.gov for more information.

Forms can be downloaded from BCD.

Frequently Asked Questions

I purchased a manufactured home, what do I need to do?
You first need to contact the Assessor of the county in which the home is located.  All taxes must be current and you must obtain a signed county notification certificate to include with your application to BCD.

The market value of my manufactured home from the most recent property tax bill is more than I paid for it. I thought manufactured homes depreciate in value so how can that be?
We have found that manufactured homes will increase or decrease in value depending on the current real estate market.  We collect data on sales of manufactured homes every year and compare the sales prices to the current real market value.  Manufactured structure values are then adjusted annually based on the sales analysis.
