Massachusetts Security Deposit Rules at a Glance
| Maximum deposit | 1 month’s rent — no more. Massachusetts landlords may only collect first month’s rent, last month’s rent, a security deposit equal to one month’s rent, and the cost of a new lock and key. No pet deposits, cleaning fees, or move-in fees are permitted. |
| Return deadline | 30 |
| Itemized deductions required | YES — the landlord must provide a sworn itemized statement of all deductions, signed under the pains and penalties of perjury, with supporting receipts, invoices, or written estimates for each deduction, delivered within 30 days after the tenant vacates. Failure to provide the itemized list within 30 days means the landlord forfeits the right to claim any deductions. |
| Interest on deposit required | YES — the landlord must pay interest at 5% per year or the actual bank interest rate earned, whichever is less. Interest must be paid annually at the end of each year of tenancy and at the end of the tenancy. If the landlord fails to deposit the money in a bank account, the tenant is entitled to the full 5% annually. The tenant is entitled to interest only if they remain for at least one year. |
| Penalty for late/bad-faith return | Massachusetts imposes mandatory treble (3x) damages — the court awards three times the amount of the security deposit wrongfully withheld, plus attorney’s fees and court costs. Treble damages are mandatory, not discretionary, and the court has no authority to reduce them. Bad faith is not required — strict liability applies for procedural violations such as failure to return the deposit within 30 days, failure to hold the deposit in a proper separate account, or failure to provide the Statement of Condition. If the landlord misses the 30-day deadline, the landlord forfeits the entire deposit and owes 3x damages. |
Move-in/move-out walkthrough: Massachusetts does not require a joint move-in or move-out walkthrough inspection. However, the landlord must provide the tenant with a written Statement of Condition within 10 days of receiving the deposit or the start of tenancy. This statement must list all existing damage to the unit, including common areas.
The tenant has 15 days to return a corrected copy if they disagree with any item. If the landlord fails to provide the Statement of Condition, the landlord cannot make any deductions for damage. This requirement effectively substitutes for a formal move-in inspection.
Separate deposit account: YES — the deposit must be placed in a separate, interest-bearing account in a Massachusetts bank within 30 days of receipt. The account must be beyond the reach of the landlord’s creditors. The landlord must provide the tenant with a written receipt showing the bank name, bank address, and account number.
A pooled account holding only security deposits and prepaid rent is permitted — a separate account per tenant is not required. Failure to comply entitles the tenant to demand immediate return of the full deposit plus 3x damages.
What Your Landlord Can and Cannot Deduct in Massachusetts
Massachusetts law limits deductions to: (1) unpaid rent that has not been validly withheld or deducted under other law; (2) unpaid water or sewer charges if the lease requires the tenant to pay these; (3) damage to the unit beyond normal wear and tear caused by the tenant, their guests, or occupants; (4) costs to store and dispose of property abandoned by the tenant; and (5) real estate tax increases only if the lease contains a valid tax escalation clause.
No other deductions are permitted — cleaning fees, carpet shampooing for normal use, and repainting for normal fading are not allowable.
Normal wear and tear vs damage: Massachusetts does not provide a statutory definition, but courts distinguish normal wear and tear from tenant damage. Normal wear and tear (not deductible) includes faded paint from sunlight, minor scuff marks from furniture, lightly worn carpet in traffic areas, small nail holes from hanging pictures, minor dust or dirt removable by routine cleaning, and general aging consistent with the length of tenancy.
Tenant damage (deductible) includes large holes in walls, pet-torn or deeply stained carpet, burns on surfaces, broken fixtures, unauthorized paint requiring full priming and repainting, and deep stains requiring replacement. Courts consider the nature and cause of the condition, expected deterioration from reasonable residential use, the move-in Statement of Condition, and the length of tenancy — longer tenancy means more wear is expected.
How to Get Your Deposit Back in Massachusetts
A Massachusetts tenant can dispute wrongful deductions by: (1) sending a written demand letter (certified mail recommended) to the landlord disputing the deductions and requesting return of the deposit; (2) filing a complaint with the Massachusetts Attorney General’s Office, Consumer Protection Division; (3) filing a claim in Small Claims Court for amounts up to 7000, where no attorney is required; or (4) filing in District Court or Housing Court for amounts over 7000.
Many tenants recover 3x the deposit plus attorney fees and costs. If the landlord did not provide a timely itemized statement, the landlord cannot defend the deductions in court. Filing in Small Claims means the tenant waives the right to appeal.

Other Massachusetts deposit rules: Massachusetts is one of the strictest states for security deposit protections. Key unique rules: (1) Statement of Condition — the landlord must provide a written statement listing all existing damage within 10 days of receiving the deposit, and the tenant has 15 days to dispute it; failure to provide this voids the right to deduct for damage.
(2) Mandatory treble damages without requiring bad faith — unlike most states, 3x damages are automatic for any procedural violation.
(3) Forfeiture for any procedural error — missing the 30-day return deadline, failing to hold the deposit in a separate account, failing to provide bank information, or failing to provide the Statement of Condition each independently cause the landlord to forfeit the entire deposit. (4) Sworn statement under perjury — the itemized deduction list must be signed under pains and penalties of perjury.
(5) Prohibition on non-refundable fees — no pet deposits, cleaning fees, move-in fees, or any charge beyond first month, last month, security deposit, and lock/key cost. (6) Annual interest payment obligation — landlords must proactively pay interest to the tenant each year, not just at move-out.
(7) Receipt with bank details required — the landlord must disclose the bank name, address, and account number within 30 days of receiving the deposit.
(8) 2025 amendment effective August 1, 2025 — Massachusetts now permits landlords and tenants to agree on a non-refundable fee in lieu of a traditional security deposit, but this arrangement is optional and must be mutually agreed upon. The governing statute is MGL Chapter 186, Section 15B.
