Re: Demand for return of security deposit — [rental address]
Dear [Landlord name],
I vacated [rental address] on [move-out date] and provided a forwarding address. To date I have received neither my security deposit of [$amount] nor an itemized statement of deductions.
Mass. Gen. Laws ch. 186 § 15B requires a landlord in Massachusetts to deliver the deposit, or an itemized statement of deductions, within 30 calendar days after the tenancy ends. That period expired on [deadline date].
I request payment of [$amount] within 14 days of the date of this letter, sent to the address above.
If I do not receive it, I intend to file in small claims court. Three times the deposit plus interest, court costs and attorney's fees for certain violations.
Sincerely,
[Your name]
Massachusetts questions
In MA, a landlord has 30 days to return your security deposit or send an itemized statement of deductions (Mass. Gen. Laws ch. 186 § 15B).
Yes. They are calendar days, not business days, and they run from the date the tenancy ended.
Three times the deposit plus interest, court costs and attorney's fees for certain violations. A dated demand letter sent by certified mail is the evidence a court will expect to see that you asked first.
One month's rent.
It isn't required, but judges expect it. A dated letter with a certified-mail receipt is the cleanest evidence that you gave the other side a chance to resolve it.
