Massachusetts has the toughest security deposit law in the country, codified at M.G.L. c. 186, § 15B. Landlords face triple damages, attorney's fees, and loss of their right to any deduction for even minor technical violations. As a Massachusetts tenant, you hold real leverage. Before you sign a lease, make sure your landlord provides the statutorily required receipt, interest-bearing account disclosure, and condition statement.
What is a Security Deposit?
A security deposit in Massachusetts is money held by a landlord to secure performance of the tenant's lease obligations. It is governed by M.G.L. c. 186, § 15B, which imposes specific escrow, receipt, interest and return requirements. Deposits are treated as the tenant's property at all times, held in trust.
Red flags to watch for
M.G.L. c. 186, § 15B(1)(b) caps security deposits at one month's rent.
§ 15B(2)(a) requires this receipt. Failure forfeits the landlord's right to retain the deposit.
§ 15B(3)(a) mandates a separate Massachusetts bank account. Commingling or out-of-state accounts are violations.
§ 15B(2)(c) requires landlords to provide a detailed condition statement listing any existing damage. Tenants have 15 days to return it with corrections.
§ 15B(3)(b) requires the landlord to pay interest annually or credit it against rent.
Under § 15B(4), deductions are permitted only for unpaid rent, tax escalation, or damages beyond reasonable wear and tear — itemised and sworn under penalty of perjury.
Your legal rights
M.G.L. c. 186, § 15B provides the most tenant-protective security deposit law in the United States. Key rights: one-month cap, mandatory receipt within 30 days, separate Massachusetts bank account with disclosure, 5% or actual interest paid annually, written statement of condition within 10 days, detailed itemisation of deductions within 30 days of move-out, and triple damages plus attorney's fees for violations under § 15B(7). Housing Court and District Court enforce.
