Arizona Revised Statutes Title 42. Taxation § 42-16162. Decision of the state board

A. Based on the evidence presented at a hearing on an appeal, the state board shall either grant or refuse the request of the petition, in whole or in part, as the state board considers just and proper. The decision of the state board shall not exceed the assessor's noticed valuation and recommended classification. A decision by the state board does not limit a party from appealing the decision in a manner prescribed by law. The state board may increase individual parcels within an economic unit in a multiple parcel appeal when considering the equitable valuation of an economic unit not to exceed the total aggregate valuation of the multiple parcel appeal on the agreement of both parties.

B. In considering any petition filed by any person, the state board shall review and consider all competent evidence relating to full cash value, including, if presented, the valuation of similar property that is similarly situated.
