Subject to subsections (b), (c), and (d) of this section, an insurer may issue a policy of homeowner’s insurance that includes a deductible that is equal to a percentage of the “Coverage A – Dwelling Limit” of the policy. The insurer may: require the deductible described in paragraph (1) of this subsection in a policy of the homeowner’s insurance; or offer the deductible described in paragraph (1) of this subsection as an option to an applicant or insured. An insurer that has adopted an underwriting standard that requires a mandatory hurricane deductible equal to a percentage of the “Coverage A – Dwelling Limit” of the policy shall apply the deductible: only beginning at the time the National Hurricane Center of the National Weather Service issues a hurricane warning for any part of the State and ending 24 hours following the termination of the last hurricane warning issued for any part of the State; and regardless of where the insured’s home is located in the State. An insurer that issues a policy of homeowner’s insurance may not adopt an underwriting standard that requires a deductible that exceeds 5% of the “Coverage A – Dwelling Limit” of the policy in the case of a hurricane unless the insurer has filed the underwriting standard with the Commissioner. The filing required by paragraph (1) of this subsection shall: be made at least 60 days before the insurer proposes to implement the underwriting standard in the State; and include: a copy of the underwriting standard the insurer intends to implement; and the date on which the insurer intends to implement the underwriting standard. An underwriting standard subject to this subsection shall comply with all applicable laws. An insurer that issues a policy of homeowner’s insurance that includes a deductible that is equal to a percentage of the “Coverage A – Dwelling Limit” of the policy or has adopted an underwriting standard that requires a mandatory hurricane deductible equal to a percentage of the “Coverage A – Dwelling Limit” of the policy shall provide a policyholder with an annual statement explaining the manner in which the deductible is applied in accordance with § 19–209.1 of this subtitle. The insurer shall send a copy of the form used to provide the statement required under paragraph (1) of this subsection to the Commissioner prior to its use.
