Annual Pause of Multnomah County Property Data Sharing
The Multnomah County Division of Assessment & Taxation pauses property data sharing annually, sometime between late summer and early fall, as they process annual tax statement payments. You will likely notice discrepancies on the related Property and Owner People records compared to what is listed on the Multnomah County Property website. The City of Portland does not have an estimated date for when they will pause and resume their data sharing. City-maintained property data, such as information displayed in PortlandMaps, that uses Multnomah County data will become outdated during this period.
Assessor Data Discrepancies
For more information regarding how to change assessor data discrepancies like property ownership name and improvements for properties please contact the appropriate county below. These divisions' ownership sections can also review requests to remove a name based on some limited public safety provisions. To make a request to exempt personal information from disclosure with the City of Portland for public records requests, visit the Safety Exemptions for Public Records Requests ↗ webpage.

Building Permits & Assessment Timeline
Building permits are worked by the Multnomah County Assessment, Recording & Taxation office in the year following issuance. The assessment date for a property is January 1st of each year. If a house was not built prior to January 1 then you will not see anything updated on the record until the following year. Assessment values are not finalized until mid-September of each year following the January 1 assessment date. Once the appraiser has done the site visit and inspection, it typically is only a few weeks until the records are updated.
