The triennial assessment system established in 1979 requires that all real property be valued once every three years based on a physical inspection of the real property. Each county assessment office has identified and reviews yearly one-third of their accounts.

For purposes of clarity and uniformity in communications, reports, and instructions, please refer to the established property grouped accounts as follows:

Group 1 - The one-third for 1979 Physical Review
Group 2 - The one-third for 1980 Physical Review
Group 3 - The one-third for 1981 Physical Review

Each group maintains this unique identification regardless of which year of the assessment cycle it is in​.
