Subdivision (a) of Section 1013 of the Code of Civil Procedure shall be applicable if the notice is mailed.(c) An insurer, at least 60 days, but not more than 120 days, in advance of the end of the policy period, shall give notice of nonrenewal, and the reasons for the nonrenewal, if the insurer intends not to renew the policy, or to condition renewal upon reduction of limits, elimination of coverages, increase in deductibles, or increase of more than 25 percent in the rate upon which the premium is based.(d) If an insurer fails to give timely notice required by subdivision (c), the policy of insurance shall be continued, with no change in its terms or conditions, for a period of 60 days after the insurer gives the notice.(e) With respect to policies defined in subdivision (b) of Section 676.6, in addition to the bases for conditional renewal set forth in subdivision (c), an insurer may also condition renewal upon requirements relating to the underlying policy or policies.
