Your Rights Under Mass. Gen. Laws ch. 186, § 15B
Under Mass. Gen. Laws ch. 186, § 15B, landlords in Massachusetts must return a tenant's security deposit — or the balance after lawful deductions — within 30 days after the tenancy ends and the tenant vacates the unit. Along with the return, the landlord must provide a written, itemized statement of any deductions within 30 days. Failure to provide this statement is independently actionable.
If a landlord fails to return the deposit within 30 days, Massachusetts law provides for 3x the wrongfully withheld amount as damages.
Massachusetts requires landlords to pay interest on security deposits held for longer tenancies. The current rate is approximately 5.00% per year. Interest must be paid when the deposit is returned.
What Your Landlord CAN Deduct
These deductions are permissible under Massachusetts law when properly documented.
- Unpaid rent
- Damage beyond normal wear and tear
- Cleaning if lease requires and unit was left dirty
- Lease-break fees if specified in lease
- Costs to replace items tenant removed or kept
