Keeping, depositing, and holding the deposit

A security deposit remains the property of the tenant until a landlord is authorized to use it. Therefore, a landlord is required to keep a tenant’s security deposit in a separate, interest-bearing bank account in Massachusetts. Each account must also be clearly identified as containing funds that don’t belong to the landlord and are being held in trust (escrow) for the tenant.  

Within 30 days of depositing the security deposit, the landlord must give the tenant in writing:

  • The name and location of the bank where the deposit is being held
  • The amount of the deposit
  • The account number  
30 days how long the landlord has to give the tenant security deposit information.


If a landlord doesn’t hold a tenant’s security deposit in the proper type of account or fails to give the tenant the required notice of where the funds are deposited, the landlord loses the right to keep the security deposit. At the request of the tenant, the landlord must immediately return the security deposit to him or her.

Interest on a deposit

A security deposit remains the tenant’s property. Therefore, if the tenancy lasts for a year or longer, the landlord is required to pay interest on the deposit to the tenant. The tenant is entitled to the amount of interest actually paid by the bank on the deposit. However, if the landlord fails to deposit the security deposit in a bank, the tenant is entitled to interest at an annual rate of 5 percent. At the end of each year of the tenancy, the landlord may either pay the interest to the tenant or deduct it from the tenant’s next rent payment.

Changing ownership

What happens to a tenant’s security deposit if the property changes owners during the tenancy?

If the landlord sells the property or otherwise no longer owns or manages it, the landlord must transfer the tenant’s security deposit, including interest, to the new owner or property manager, who then becomes responsible for holding it. The new owner or manager has 45 days to give written notice to the tenant of receipt of the security deposit and where it is now being held.

If the former landlord doesn’t properly transfer the funds being held in the tenant’s security deposit account to the new owner or manager, the former landlord remains responsible to the tenant for returning the security deposit. The new owner or manager is also responsible to the tenant for the security deposit (unless the property is now owned by a foreclosing bank or the city/town), which may be satisfied by allowing the tenant to not pay rent for the amount of time equal to the amount of the security deposit and interest.
