In Massachusetts, a landlord must return a security deposit within 30 calendar days

Quick answer

A Massachusetts landlord has 30 calendar days after you return possession to return your deposit or send an itemized list of deductions. Miss it in bad faith and the landlord can end up owing you more than the deposit itself.

Under Massachusetts security deposit law, a Massachusetts landlord has 30 calendar days to return your security deposit, counted from when you return possession. By statute, the deposit is capped at 1 month's rent. If the landlord misses the deadline or keeps money you are owed, you can push back in writing and, if needed, in small claims court.
