A decision regarding the necessity of reappraisal must often be made based on what?

The necessity of reappraisal is often dictated by statutes or administrative rules because these regulations set specific guidelines and requirements for property assessment practices. These legal frameworks can establish conditions under which reappraisal is not only allowed but also required, ensuring that assessments maintain fairness and equity in relation to property values.

Market trends, appraiser opinions, and property sales history are all important factors in the assessment process, but they serve more as indicators or tools for appraisers rather than direct mandates for reappraisal. Statutes or administrative rules provide the foundational legal authority that governs when and how reappraisals should be conducted, ensuring compliance with broader regulatory requirements. This makes adherence to such rules a primary consideration for assessment professionals determining the timing and necessity of reappraisals.
