Selected cases

Castenholz v. Caira , 21 Mass. App. Ct. 758 (1986)
If a landlord does not place a security deposit in an escrow account within 30 days of receipt, and fails to return the security deposit to the tenant, and the tenant must go to court to get the money back, the landlord must pay triple damages, interest, costs, and attorney’s fees.

Dolores v. Gustafson , 2009 Mass. App. Div. 267 (2009)
Even if the landlord returns the security deposit within 30 days of the end of the tenancy, triple damages may apply if the landlord has not followed any of the other provisions of the law that trigger triple damages, such as keeping the money in a separate account or providing a proper itemized list of damage and repairs made.

Karaa v. Yim, 86 Mass. App. Ct. 714 (2014)
“Landlord’s failure to return deposit within thirty days did not trigger treble damages provision, where tenant offered security deposit as compensation for their own breach of lease.”

Phillips v. Equity Residential Management, LLC, 478 Mass. 251 (2017)
Not all violations of the security deposit act call for triple damages. A tenant is only entitled to recover triple damages for those violations of the act that specifically call for an award of triple damages.

The security deposit law applies to assisted living residences, but those residences can also charge additional up-front fees for the unique services they provide.

Placing the money in an out-of-state bank does not conform to the statute.
