(B) The tenant shall not unreasonably withhold consent for the landlord to enter into the dwelling unit in order to inspect the premises, make ordinary, necessary, or agreed repairs, decorations, alterations, or improvements, deliver parcels that are too large for the tenant's mail facilities, supply necessary or agreed services, or exhibit the dwelling unit to prospective or actual purchasers, mortgagees, tenants, workmen, or contractors.
(C)(1) If the tenant violates any provision of this section, other than division (A)(9) of this section, the landlord may recover any actual damages that result from the violation together with reasonable attorney's fees. This remedy is in addition to any right of the landlord to terminate the rental agreement, to maintain an action for the possession of the premises, or to obtain injunctive relief to compel access under division (B) of this section.
(2) If the tenant violates division (A)(9) of this section and if the landlord has actual knowledge of or has reasonable cause to believe that the tenant, any person in the tenant's household, or any person on the premises with the consent of the tenant previously has or presently is engaged in a violation as described in division (A)(6)(a)(i) of section 1923.02 of the Revised Code, whether or not the tenant or other person has been charged with, has pleaded guilty to or been convicted of, or has been determined to be a delinquent child for an act that, if committed by an adult, would be a violation as described in that division, then the landlord promptly shall give the notice required by division (C) of section 5321.17 of the Revised Code. If the tenant fails to vacate the premises within three days after the giving of that notice, then the landlord promptly shall comply with division (A)(9) of section 5321.04 of the Revised Code. For purposes of this division, actual knowledge or reasonable cause to believe as described in this division shall be determined in accordance with division (A)(6)(a)(i) of section 1923.02 of the Revised Code.
