Relating to the appraisal for ad valorem tax purposes of land subject to a quarantine established by the Texas Animal Health Commission for ticks or screwworms.

HB 239 modifies Texas property tax rules for land affected by animal health quarantines. It allows landowners to request a reappraisal of their property during active Texas Animal Health Commission quarantines (lasting 90+ days) for ticks or screwworms. The bill caps the reassessed value at half the original appraised value or the current market value, whichever is lower, to account for reduced land usability during the quarantine. This directly affects Texas agricultural landowners whose properties are under such quarantine orders, providing temporary tax relief while the quarantine remains in effect.
