(c) The landlord may claim of the payment or deposit only those amounts as are reasonably necessary to remedy tenant defaults in the payment of rent, to repair damages to the premises caused by the tenant, or to clean the premises upon termination of the tenancy, if the payment or deposit is made for any or all of those specific purposes.

1. (1) If the claim of the landlord upon the payment or deposit is only for defaults in the payment of rent and the security deposit equals no more than one month’s rent plus a deposit amount clearly described as the payment of the last month’s rent, then any remaining portion of the payment or deposit shall be returned to the tenant at a time as may be mutually agreed upon by landlord and tenant, but in no event later than 30 days from the date the landlord receives possession of the premises.
2. (2) If the claim of the landlord upon the payment or deposit is only for defaults in the payment of rent and the security deposit exceeds the amount of one month’s rent plus a deposit amount clearly described as the payment of the last month’s rent, then any remaining portion of the payment or deposit in excess of an amount equal to one month’s rent shall be returned to the tenant no later than two weeks after the date the landlord receives possession of the premises, with the remainder to be returned or accounted for within 30 days from the date the landlord receives possession of the premises.
3. (3) If the claim of the landlord upon the payment or deposit includes amounts reasonably necessary to repair damages to the premises caused by the tenant or to clean the premises, then any remaining portion of the payment or deposit shall be returned to the tenant at a time as may be mutually agreed upon by landlord and tenant, but in no event later than 30 days from the date the landlord receives possession of the premises.

(d) Upon termination of the landlord’s interest in the unit in question, whether by sale, assignment, death, appointment of receiver or otherwise, the landlord or the landlord’s agent shall, within a reasonable time, do one of the following acts, either of which shall relieve the landlord of further liability with respect to the payment or deposit:

1. (1) Transfer the portion of the payment or deposit remaining after any lawful deductions made under subdivision (c) to the landlord’s successor in interest, and thereafter notify the tenant by personal delivery or certified mail of the transfer, of any claims made against the payment or deposit, and of the transferee’s name and address. If the notice to the tenant is made by personal delivery, the tenant shall acknowledge receipt of the notice and sign his or her name on the landlord’s copy of the notice.
2. (2) Return the portion of the payment or deposit remaining after any lawful deductions made under subdivision (c) to the tenant.
