(B) The landlord or qualified inspector may initially conduct a visual and manual inspection of the tenant's bedding and upholstered furniture. The landlord or qualified inspector may inspect items other than bedding and upholstered furniture when such landlord or qualified inspector determines that such an inspection is necessary and reasonable. If the landlord or qualified inspector finds bed bugs in the dwelling unit or in any contiguous unit of which the landlord is an owner, lessor or sublessor, such landlord or qualified inspector may have such additional access to the tenant's personal belongings as the landlord or qualified inspector determines is necessary and reasonable. A tenant shall comply with reasonable measures to permit the inspection and treatment of a bed bug infestation as determined by the landlord and qualified inspector or pest control agent, and such tenant shall be responsible for all costs associated with preparing a dwelling unit for such inspection and treatment. The tenant's knowing and unreasonable failure to comply with such bed bug inspection and treatment measures shall result in the tenant being held liable for those bed bug treatments of the dwelling unit and contiguous units arising from such failure.
