(a) The use of the antiarson application shall be mandatory for commercial monoline fire policies, designated occupancies, and designated areas of the state, based upon a finding by the Insurance Commissioner, after a public hearing, that the commercial monoline fire policies, the designated occupancies, and the areas of the state have an abnormally high incidence of arson.
(b) However, if the commissioner desires to extend the application of this subchapter to other than commercial monoline fire policies, he or she must first find, after public hearing, that the properties insured through those other types of policies are especially prone to arson.
(c) Designation of any area of the state under this subchapter shall not be deemed a valid reason for refusal to write, for termination, or for nonrenewal of any policy or contract of insurance.
