In the event of a state of emergency, as defined in Section 8558 of the Government Code, an insurer shall offer a 60-day grace period for payment of premiums for residential property insurance policies covering a property located within the affected area defined in the state of emergency for a period of 60 days after the emergency. This section does not require any change to insurer billing practices regarding billing, automatic payment, or cancellation for nonpayment if the insurer reinstates, without a lapse in coverage or late fees, any policy subject to this section that was canceled for nonpayment of premiums, if requested by the insured and upon reasonably timely payment of all premiums due.
