Taxation and Finance Oregon 3 Minutes Read ยท published February 20, 2026 Flag of Oregon

In Eugene, Oregon, property assessments are set at the county level but directly affect city taxpayers. This guide explains how to challenge an assessed value, who enforces assessment rules, and the practical steps to request informal reviews or file a formal appeal. Start by checking your assessment notice and contacting the county assessor for an informal review, then gather comparable sales, appraisal reports, and error evidence before filing any formal petition. The process involves both administrative review and, if necessary, a hearing before the county appeal board; below are the steps, forms, enforcement details, and official contacts you will need.

How the Assessment Appeal Process Works

Typical steps are an informal review with the assessor, a formal petition to the county review board, and a hearing if the dispute continues. Evidence commonly used includes recent sales comparables, certified appraisals, photographs showing condition issues, and records of clerical errors. Start with the Lane County Assessor to request an informal review or instructions for filing a petition. [1]

  • Request informal review from the assessor as soon as you receive the assessment notice.
  • Assemble evidence: recent comparable sales, appraisal reports, inspection photos.
  • If unresolved, file a formal petition with the county appeal board following the assessor's instructions.
  • Attend the hearing and present your evidence; the board issues a written decision.

Specific monetary penalties and escalation amounts are not specified on the cited pages; consult the assessor and Oregon Department of Revenue for exact sanctions. [2]

  • Enforcer: Lane County Assessor and the county property tax appeal board; contact the assessor for inspection and complaint pathways. [1]
  • Appeal/review routes and time limits: follow instructions on the county assessor's appeal page; exact filing deadlines are not specified on the cited pages.
  • Defences and discretion: clerical errors, incorrect classification, documented market value evidence, and approved exemptions or reductions (such as homestead or special assessments) when applicable.

Applications & Forms

The specific petition form name or number required to file a formal appeal should be obtained from the county assessor or the board of appeals. Lane County posts instructions and forms through the assessor's office; if a named statewide form is required, refer to the Oregon Department of Revenue property pages for statewide procedures. [2] If no form is published on the assessor's site, the assessor will provide filing instructions.
