Assessment Procedures Library – Authority, Practical Examples, Periodic Updates
Authority
Authority for the Arizona Department of Revenue (Department) to produce the publications in the Assessment Procedures Library is found in Arizona Revised Statutes (A.R.S.) 42-11054(A) (1) and (2). Regarding the weight of authority of these publications, see A.R.S. 42-13051(B)(2).
Practical Examples
All practical examples within the publications that comprise the Assessment Procedures Library are representative of how the Department would apply a given set of data while adhering to both industry and Arizona-specific guidelines as well as standard appraisal methods and techniques. Practical examples may demonstrate the current best practices used to make a necessary determination. Some practical examples may demonstrate the application of a process mandated by statute. See A.R.S. 42-11001(6). Other practical examples may demonstrate methods that are adaptable to the particular situations of the various counties. Specific calculations used in the practical examples found within these publications are for demonstration purposes only.
Periodic Updates
The Department periodically updates the publications in the Assessment Procedures Library, consistent with the following three levels of updates, depending on the perceived need:
Review: Publication conforms to standard style and formatting. Legislative and other citations verified. No changes to content, methodology, policy, or practice.
Revision: Includes applicable Review processes. Publication is newly edited. Nonsubstantive legislative changes incorporated. Addition or deletion of information that does not alter valuation methodology.
Rewrite: Includes applicable Review and Revision processes. Major substantive changes made to any combination of content, valuation methodology, policy, or practice.
