(a) Except as otherwise provided by this subsection, a rate approved by the commissioner under this subchapter may not reflect an average rate change that is more than 10 percent higher or lower than the rate for commercial windstorm and hail insurance or 10 percent higher or lower than the rate for noncommercial windstorm and hail insurance in effect on the date the filing is made. The rate may not reflect a rate change for an individual rating class that is 15 percent higher or lower than the rate for that individual rating class in effect on the date the filing is made. This subsection does not apply to a rate filed under Sections 2210.351(a)-(d).
(b) The commissioner may, after notice and hearing, suspend this section on a finding that a catastrophe loss or series of occurrences resulting in losses in the catastrophe area justify a need to ensure:
(1) rate adequacy in the catastrophe area; and
(2) availability of insurance outside the catastrophe area.
