Did your Massachusetts landlord your landlord kept part or all of your deposit but refused to provide a detailed, itemized list of deductions with actual receipts or invoices?

Q: Can I demand my Massachusetts security deposit back if my landlord your landlord kept part or all of your deposit but refused to provide a detailed, itemized list of deductions with actual receipts or invoices?

Yes. Under Massachusetts General Laws c. 186 § 15B, landlords are strictly regulated in how they handle security deposits. Most states explicitly require an itemized written statement — with actual receipts or invoices — whenever a landlord withholds any portion of a deposit. Providing a vague list of charges without backup documentation is itself a statutory violation that often voids the entire deduction. You may be entitled to recovery of the deposit, three times the amount wrongfully withheld as statutory damages, interest on the deposit, and court costs and attorney's fees.

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

Governing statute — Massachusetts

Massachusetts General Laws c. 186 § 15B

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

Most states explicitly require an itemized written statement — with actual receipts or invoices — whenever a landlord withholds any portion of a deposit. Providing a vague list of charges without backup documentation is itself a statutory violation that often voids the entire deduction.

Statutory deadline

30 days

Evidence to lock in your claim

Save every communication where you requested the itemization, document the date you first asked, and note whether the landlord provided actual paid invoices or only rough estimates. Many states require receipts within a strict window; failure to provide them voids the deduction.

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.
