Insurance Code (usually included in commercial codals)
Section 66. In case of insurance other than life, unless the insurer at least forty-five days in advance of the end of the policy period mails or delivers to the named insured at the address shown in the policy notice of its intention not to renew the policy or to condition its renewal upon reduction of limits or elimination of coverages, the named insured shall be entitled to renew the policy upon payment of the premium due on the effective date of the renewal. Any policy written for a term of less than one year shall be considered as if written for a term of one year. Any policy written for a term longer than one year or any policy with no fixed expiration date shall be considered as if written for successive policy periods or terms of one year.
