Move-in/move-out checklist

A landlord may not collect a deposit unless the lease is written and the tenant gets, at move-in, a signed and dated checklist describing the condition of walls, flooring, furniture, appliances and other items. A landlord who collects a deposit without the checklist is liable for the deposit amount.
