The Board of Assessment Appeals (BAA) hears appeals filed by real and personal property owners regarding the valuation placed on their property. The County Assessor is responsible for valuing all property in the county except for exempt property and state assessed properties. Taxpayers may appeal the assigned value to the Assessor and the County Board of Equalization (valuation appeal) or to the Board of County Commissioners (abatement).

State assessed properties and exemptions are appealed to the Property Tax Administrator. These cases may then be appealed to the BAA. Appeals can also be filed when a County Board of Commissioners or a County Board of Equalization has failed to make a timely decision on a matter properly presented.

Taxpayers and counties have the option to request a pre-hearing conference which provides an opportunity to meet with the Board’s staff in advance of a hearing to clarify issues and to reach agreements that may simplify the hearing.

Hearings held in person and by video conference may be live streamed. In such cases, please visit the BAA YouTube Channel. Due to current COVID 19 precautions all Board hearings are being held via Zoom video conference.
