(3) (A) A landlord shall offer to make reasonable assistance available to a tenant who is not physically able to comply with preparation for any bed bug inspection or treatment measures that are the tenant's responsibility under this section. The landlord shall disclose to the tenant the cost, if any, of providing such assistance to the tenant. The landlord may, at the landlord's discretion, charge the tenant a reasonable amount for any such assistance, provided such charge is subject to a reasonable repayment schedule not to exceed six months, unless the landlord and tenant agree to one or more extensions of such repayment schedule. A tenant's failure to agree to any such charges or repayment schedule shall not relieve the landlord of the duty to treat the dwelling unit.
