Oregon has no statutory assessment ratio. Measure 50 (Or. Const. art. XI, § 11) set each property's maximum assessed value at 90% of its 1995-96 real market value and caps growth at 3% a year, so assessed value is the lesser of MAV and real market value and drifts below market over time. 0.536 is the statewide ratio of assessed value to real market value the Department of Revenue reports for FY 2025-26, up from 0.526 in FY 2024-25.
