What to do if you receive a postcard in the mail from the Assessor's Office.

Attention Homeowner:

Thank you for scanning the QR code on the postcard you received in the mail. You received this postcard because your property has been identified as one to be reviewed this year. Appraisal staff may visit your property and others in your neighborhood.

Appointments are optional. If you would like to schedule an appointment, or if you have questions, email is preferred at: ResidentialCustomerService@multco.us or leave a voicemail at (503) 988-0078 with your preferred phone number, email, and a detailed message including the dates and times you would be available for an inspection appointment.

Oregon law requires County Assessors to value properties each year. To accomplish this, appraisers from the Multnomah County Assessor’s office review property records and visit select properties.

What types of properties are assessed? 

2023 Assessments

Property Values for 2023-2024 Property Taxes were determined as on January 1, 2023, and are not necessarily reflective of current market conditions.

Please remember, you cannot appeal the amount of your property taxes. You may only appeal the value of your property if you feel it is incorrect.  If you decide to appeal, please keep in mind that you are appealing the value as of January 1, 2023. 

Not all value reductions from an appeal will result in tax savings.

For more information, please contact our office.


County appraisers determine your property's values via a variety of methods. Why is there an appraiser at my house? 


If you disagree with the value county appraisers have given to your property, you may appeal your property value. You cannot appeal how much you owe in taxes, only how much your property has been valued. If your appeal is successful and the value of your house decreases, you may pay lower taxes. Appeals must be filed by December 31 of the year in which your property was assessed.
