Section 50IAC27-5-1. Adjustment factors

   (a) In the annual adjustment process the county assessor shall reevaluate the factors that affect value each year, express the interactions of those factors mathematically, and use mass appraisal techniques to estimate property values to reflect a property's market value-in-use. Thus, it is necessary to observe and evaluate, but not always to change, the assessment of each property each year in order to achieve current market value-in-use. Value calibration analysis studies performed by the county assessor will indicate where equalization action is needed to ensure annual equalization within the county.

  (b) The annual adjustment process does not mean that each assessed valuation must be reviewed or recomputed individually. Instead, adjustment factors based on criteria such as property class, type, location, size, and age will be developed and applied to stratified groups of properties. These adjustment factors shall be derived from market value-in-use calibration analyses.

  (c) Adjustment factors are not a substitute for physical reviews and individual reappraisals or reassessments, which are required to correct lack of uniformity within a class of property, and to obtain property characteristics data required by 50 IAC 27-3-1.
