Maryland Insurance Section 19-107

      (a)      An insurer may not refuse to issue or renew a contract of motor vehicle insurance, property insurance, or casualty insurance solely because the subject of the risk or the applicant's or insured's address is located in a certain geographic area of the State unless:

            (1)      at least 60 days before the refusal, the insurer has filed with the Commissioner a written statement designating the geographic area; and

            (2)      the designation has an objective basis and is not arbitrary or unreasonable.
