Overview of Valuation Methods

Local assessed values derive from standard appraisal approaches: market (sales) comparison, cost (replacement cost less depreciation), and income (capitalization of expected income for income-producing properties). County assessors apply mass-appraisal techniques for roll production and adjust by local sales. Property categories (residential, commercial, industrial, exempt) follow definitions used by the assessor and state guidance.

Market data and assessor schedules determine most valuations.

How Assessments Are Used

  • Annual valuation and assessment rolls are prepared for taxation and budgeting.
  • Assessed values inform property tax bills and are used by municipal budgeting processes.
  • Certain changes (exemptions, new construction) require filings or permits with the assessor or planning departments.

Valuation enforcement and remedies in Eugene are administered through the county assessor, county appeal boards, and ultimately state courts where applicable. Specific monetary fines tied directly to assessment errors or valuation disputes are not specified on the cited pages; remedies more commonly involve correction of the roll, refunds, or tax adjustments rather than fixed fines.
