Return security deposit with itemized statement of damages within 30 days of move-out. Massachusetts law (M.G.L. c. 186 s. 15B) requires returning the deposit and its accrued interest within 30 days after the tenancy ends, with any deduction for damage backed by a sworn, itemized list and repair estimates or receipts delivered within the same 30 days, and missing the deadline or failing to hold the deposit in a separate Massachusetts bank account triggers three times the amount due plus 5% interest, court costs, and attorney fees.
