Landlord & Tenant Laws in Massachusetts.

A tenant should preserve the statement of condition, move-in records, and any receipts or communications because Massachusetts ties many deposit rights to strict documentation and procedural requirements.

In Massachusetts, a landlord generally must return the security deposit within 30 days after the tenancy ends, together with any required interest and an itemized list of lawful deductions supported by proper documentation.

If a landlord fails to follow Massachusetts security-deposit rules, the tenant may be able to recover the deposit and, in the right case, treble damages, interest, costs, and attorney’s fees.
