Proposed Changes & Improvements

  • Use the county assessed value as the baseline value for calculating the difference vs. going through a costly and time consuming appraisal process.

  • Charge only a percentage of the determined value for changes to residential (less than 10 dwellings) and farm access.

  • Charge full amount of determined value for commercial, retail, etc…

  • Charge an administrative fee for processing requests.
