If approved, the changes will take place for new policies issued on or after October 16, 2017. Should current policyholders choose to renew, they'll be affected on or after November 16, 2017.

  • 9.3% increase for Washington county residents.
  • 8.1% increase for Houston county residents.
  • 4.4% increase for Sequatchie county residents.
