Mass AppraisalAn assessed value is based on the market value of the property. However, municipalities utilize a process commonly known as mass appraisal that values hundreds or thousands of properties at once, not individually. Since the process focuses on multiple properties, their similarities and differences, it is more generalized than a single-property appraisal. The focus of mass appraisal is on the equity of the results.
Informal Assessment Reviews:   (January-early April)The informal assessment review process allows owners to submit documentation to the Assessor for review of their property's assessment. An interior and/or exterior inspection may be requested by you or the Assessor's Office if deemed necessary.

You may submit a request for an informal assessment review for the 2024 Assessment Roll to the Assessor's Office, email or by mail. All requests and supporting documentation must be received by March 31, 2024. Forms and instructions are available below. 

Results for the informal reviews:  An Assessment Notice will be mailed the first week of May with the results from the informal hearing (regardless of whether or not a change was made). Any changes made through this informal process will be found on the next available Tentative Assessment Roll (filed May 1st) and is not retroactive. If you are not satisfied with the results, you may file a a formal complaint with the Board of Assessment Review.
