Adds to and amends existing law to provide a certain requirement for a landlord and to provide a certain requirement for a security deposit.

The purpose of this legislation is to define a process for a landlord and tenant to conduct a walkthrough of the premises being rented by the tenant at the time of move in and move out. It also requires landlords to "show their work" regarding what portion of the security deposit they are keeping, and to provide an itemized receipt of charges they want to assess and the actual cost of repairs or cleaning.
