Value History under Measure 50

This search tool provides a way to locate property in Clackamas County and view a history of Real Market Value (RMV) and Maximum Assessed Value (MAV) for a specific property. Taxes are based on an Assessed Value, which is the lesser of RMV or MAV. The lower value in each year on the graph below is the Assessed Value. (Veteran exemptions amounts are deducted from the AV (before taxes are calculated) but are not reflected in this data)

Note: Graphs are not available on manufactured homes, business personal property, public utilities or on special use real property such as farm or forestland.
