Security Deposit Protection · Massachusetts

Did your Massachusetts landlord your landlord collected a security deposit larger than the maximum amount permitted by state law, or deducted more than the statutory cap allows?

Generate a formal statutory demand to claim your full refund and potential penalty damages.

Property managers cannot treat your deposit as a personal slush fund. In Massachusetts, landlords face strict statutory deadlines and limits on how much they can withhold. If your landlord has your landlord collected a security deposit larger than the maximum amount permitted by state law, or deducted more than the statutory cap allows, they may have forfeited their right to keep any of your money. Use our informational utility to generate a professional Security Deposit Demand that formally documents their violation and demands immediate payment.

Your tenant rights: Massachusetts security deposit law

Landlords often assume former tenants do not know their rights under the civil code. Here is the exact statutory reference you can use to hold them accountable in Massachusetts.

Governing statute — Massachusetts

Massachusetts General Laws c. 186 § 15B

MGL c. 186 § 15B requires landlords to return deposits within 30 days with a detailed itemized list of damages. Massachusetts also mandates that deposits be held in a separate interest-bearing account. Triple damages are available for any wrongful withholding.

Statutory leverage

recovery of the deposit, three times the amount wrongfully withheld as statutory damages, interest on the deposit, and court costs and attorney's fees

Why this withholding is illegal

A growing number of states impose strict caps on security deposits — often one or two months' rent. Collecting above that cap is unlawful from the outset, and any purported deductions taken from an unlawfully large deposit may be recoverable in full.

Statutory deadline

30 days

Evidence to lock in your claim

Locate your original lease showing the deposit amount, verify the statutory cap in effect when you signed (caps can change), calculate the difference between what you paid and the legal maximum, and gather rent receipts showing your monthly rate.

Crucial tactic: Sending a structured, formal written demand that explicitly cites MGL c. 186 § 15B signals to the landlord that you understand the law. Property managers will often immediately issue a check to avoid defending a bad-faith claim in small claims court.
