The law in plain English
Return deadline
Under Mass. Gen. Laws ch. 186, Section 15B, the deposit response usually has to be sent within 30 days of the move-out timeline described by the state rule.
Required notice
Massachusetts generally gives the landlord 30 days to return the deposit or send a compliant itemized statement, and statutory violations can trigger mandatory treble damages.
This dispute type
Painting deductions are usually weakest when the landlord is refreshing the unit for the next tenant, covering faded walls, or addressing minor marks from normal occupancy. In Massachusetts, the refund deadline and deduction notice rules still apply even if the landlord claims the walls needed work.
Penalty leverage
If the withholding was wrongful or in bad faith, the exposure allowed under the statute is: 3x the deposit, plus interest, court costs, and reasonable attorney's fees
