Frequently Asked Questions

A protest is an opportunity to demonstrate to the appraisal staff in the Assessor’s Office that your property’s assigned value or classification is inaccurate.  Your protest should provide evidence to support your position. 

Reasons to appeal include:
  • Incorrect property characteristics – property square footage, condition, bath count, use, etc.
  • Estimated value is too high – provide market data to support a reduction in value.
  • Incorrect property classification – the assessor is required to classify property based on the actual use as of January 1 of every year.

After a protest is submitted, it is assigned to a member of the appraisal staff who will review the information presented and make a determination.  A determination can either be to adjust the assigned value/classification, or deny the appeal and retain the current assigned value.  The Assessor will notify you of the determination.
