Exposure Drafts

Updates to Standard on Mass Appraisal of Real Property released for exposure

Updates to the Standard on Mass Appraisal of Real Property has been approved by the IAAO Board of Directors for exposure to members for 30 days. This standard replaces the 2018 rewrite of the standard, which replaced the April 2013 Standard on Mass Appraisal of Real Property.

This standard defines requirements for the mass appraisal of real property and the Research & Standards Committee updated the section on "Alternative to Periodic Site Inspections" with a section on "Considerations for Establishing a Property Inspection Plan." The update changes also included changing references to CAMAs to mass appraisal systems.

A clean and copy with markups are available below for review.

Comments on the standard should be sent to Assessment Advisor Shannon Hiss, RES, RMA, at hiss@iaao.org.  The comment period will run from Nov. 14 to Dec. 13, 2023.
