The Assessor works with other county departments to identify all properties with over $10,000 in structural damage. The information obtained from other agencies will aid in applying property tax reductions on a mass appraisal basis. However, property owners must complete an Application for Reassessment of Property Damaged by Calamity and submit it to the County Assessor in order to receive property tax relief. You have 12 months to file this claim from the date of the event in order to be eligible.
Visit the Assessor's Disaster Relief Page for more information.
