Open Book Inspection Period

The Open Book Inspection Period was August 12 - September 12, 2019. The dates for 2020 have not been set yet.

This "open book" inspection period is set aside to answer questions posed by property owners and to correct obvious clerical errors that were made in compiling the assessment roll.

Information about assessments and sales is available for viewing at the front counter of the Assessor's Office. This information can assist property owners when they are determining their own opinion of value. In addition, sales are available on our web page.

Comparing Assessments

Property owners wishing to review assessments may use the assessment reports located in the lobby of the Assessor's Office. Information is listed in address order and shows ownership, lot size, building data, assessment, and tax information. Assessment / tax data is also posted on the city's website. Available information includes property address, legal description, sales information, as well as details about physical characteristics.

Owners who disagree with their assessment should personally discuss it with the Assessor's Office. If an error was made, or if there is evidence that the assessment is more than the actual fair market value of property, the Assessor's Office will review the facts and may make appropriate adjustments. The best evidence of value is a recent sale of the property or sales of comparable properties.

Formal Objections

After talking with the Assessor's Office, owners who still feel that the value of property is overstated may file formal written objections to the Board of Review (BOR). Objections must be submitted to the City Clerk on forms that are available in the City Clerk's Office or on-line.

Formal objections may proceed to a formal hearing before the Board of Review. Similar to a court, the Board of Review has the responsibility for resolving differences of opinion of valuation. The Board hears oral testimony and evidence presented by the property owner and the Assessor's staff. After hearing the evidence, the Board may lower, raise, or sustain the assessment.
