Treble Damages in Massachusetts Security Deposit Cases: When 3x Applies
"Treble damages" is the phrase that gets landlords' attention, and it's often misunderstood. Massachusetts law doesn't triple every security deposit claim. M.G.L. c. 186, §15B(7) names specific violations that carry the 3x remedy. Knowing which side of the line your situation falls on is the difference between a strong demand letter and an overreaching one.
What §15B(7) actually provides
When it applies, §15B(7) says the tenant shall be awarded damages in an amount equal to three times the amount of the deposit (or the balance wrongfully withheld), plus 5% interest from the date the obligation arose, together with court costs and reasonable attorney's fees. It's one of the few Massachusetts consumer statutes with a mandatory fee-shifting provision, which is why even small deposit cases get attorneys' attention.
The violations that trigger treble damages
Section 15B(7) applies to three specific failures, listed in §15B(6) clauses (a), (d), and (e):
- §15B(6)(a): failing to deposit the money in a separate, interest-bearing Massachusetts escrow account as §15B(3) requires, which includes failing to give you the bank receipt with the account details within 30 days.
- §15B(6)(d): failing to return the deposit or balance after the landlord loses the right to hold it.
- §15B(6)(e): failing to return the deposit or lawful balance within 30 days after the tenancy ends.
The violations that do NOT triple on their own
A late, missing, or unsworn itemized list of damages (§15B(6)(b)) forfeits the landlord's right to keep deductions, but by itself it doesn't trigger treble damages. The treble exposure appears when that forfeiture leaves a balance the landlord then fails to return within 30 days, which is a (6)(e) violation.
Similarly, collecting more than one month's rent as a deposit (§15B(1)(b)) and failing to pay annual interest (§15B(3)(b)) are real violations with recoverable amounts, but the statute doesn't attach the 3x remedy to them alone.
Treble damages and the small claims limit
Massachusetts small claims court generally handles claims up to $7,000. But when a statute provides multiple damages, as §15B(7) does, the award may exceed that cap as long as the actual damages fit within it. A $3,000 deposit wrongfully withheld can support a small claims case even though trebling could put the award at $9,000 or more.
Frequently asked questions
Is treble damages automatic if my landlord missed the 30-day deadline?
No award is automatic. You'd need to bring the claim and prove the violation. But for the violations named in §15B(7), courts have treated the treble remedy as mandatory once the violation is established, which is significant leverage in a demand letter.
My landlord never gave me a bank receipt. Does that trigger 3x?
Failing to properly escrow the deposit and provide the receipt required by §15B(3)(a) is a §15B(6)(a) violation, which is one of the treble-damages triggers under §15B(7). Whether it applies depends on your specific facts.
Can I get attorney's fees in small claims court?
§15B(7) provides for court costs and reasonable attorney's fees when it applies. Many tenants handle small claims without a lawyer, in which case the fee-shifting matters less, but the exposure still strengthens your position.
