My question involves landlord-tenant law in the State of: Arizona
http://www.azleg.gov/legtext/50leg/1r/bills/sb1306s.pdf the specific law in question.


Here is the Scenario.

in May the tenant has noticed bedbugs within a used couch brought into the apartment. The tenant removes the couch and notifies the landlord immediately. There is an inspection done by a licensed professional provided by the landlord. The inspector clears the apartment stating its safe and bedbug free, but also states that there may be a chance of them returning within 3 weeks. He states if you do not see any bites within 3 weeks you are in the clear. The landlord charges the tenant for this inspection and the tenant pays for it.

Four months later, there has been no sign of bedbugs anywhere. No bites, no bugs. Then the tenant notices bites appearing and does a self inspection noticing bugs in the bed linens. The landlord is again notified the very next business day. The Tenant has not brought any new furniture into the house or knowingly done anything to re-introduce them into the environment. Both parties have agreed that the prior incident is not the cause of the bedbugs. The landlord is still claiming that the tenant is responsible to pay for a full treatment of the apartment now, stating it is their policy to charge the tenant unless the tenant can prove that the bedbugs were introduced by either negligence on the part of the apartment complex maintenance group or their employees.

Is the tenant responsible? and if not what legal recourse does the tenant have?
