Landlords are entitled to collect annual administrative expenses of one percent of the deposit. All other interest earned on the deposits belongs to the tenants. Tenants must be given the option of having this interest paid to them annually, applied to rent, or paid at the end of the lease term. If the building has fewer than six apartments, a landlord who voluntarily places the security deposits in an interest bearing bank account must also follow these rules.
For example: A tenant pays a security deposit of $800. The landlord places the deposit in an interest bearing bank account paying 2.5%. At the end of the year the account will have earned interest of $20.00. The tenant is entitled to $12.00 and the landlord may retain $8.00, 1% of the deposit, as an administrative fee.
