Massachusetts: 30-Day Rule & 3x Treble Damages

Under M.G.L. c. 186 § 15B, Massachusetts landlords must return deposits within 30 days with interest. Violations carry mandatory 3x treble damages.

Why this calculation is mathematically fair

Massachusetts enforces strict liability on deposit handling. Landlords must hold deposits in separate interest-bearing Massachusetts bank accounts, provide 30-day bank receipts, pay 5% annual interest, and provide sworn damage statements under penalty of perjury. Failing to follow these rules triggers mandatory 3x treble damages.
