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
Although the data presented here is largely the work of hundreds of dedicated individuals, the site and the applications within it were built and are maintained by Corporate GIS (CGIS), and the Bureau of Technology Services (BTS) at The City of Portland.
