Insurance Code § 678.5
CHAPTER 11. Cancellation and Failure to Renew Certain Property Insurance
No policy specified in Section 675 that is issued, amended, or renewed on or after January 1, 1990, may be canceled, and an insurer may not refuse to renew such a policy solely on the grounds of corrosive soil conditions if the policy or renewal policy contains an existing exclusion for payment of loss for that peril.
