HOUSTON – Here’s a little help for homeowners who have property damage from last week’s severe weather. The Harris County Appraisal District says you can apply for a temporary disaster exemption. A change in state law after Hurricane Harvey allows a property that is at least 15% damaged by a governor-declared disaster area to receive a temporary exemption of a portion of the appraised value of the property. This would lower your property tax bill when it is due in January.
