Selected case law

Ardon v. Kaivas, 92 Mass. App. Ct. 1110 (2017)
Intentionally depriving a tenant of access to a common area basement for a period of less than a month did not, without more, rise to the level of a substantial interference with her tenancy.

Blake v. Hometown Communities, Inc., 486 Mass. 268 (2020)
A manufactured home community charged newer residents $96 per month more than they charged other residents. This requirement that some renters pay additional rent for essentially the same lots was a violation of the Manufactured Home Act, G. L. c. 140, § 32L (2).

Creatini v. McHugh, 99 Mass. App. Ct. 126 (2021)
A landlord does not bear responsibility to a passerby in the street for injuries caused by a tenant's dog after the dog leaves the landlord's property. 

Karaa v. Yim, 86 Mass. App. Ct. 714 (2014)
Discusses mitigation of damages, stating "who bears the burden at trial regarding the mitigation of damages within the landlord-tenant context is the subject of some uncertainty in Massachusetts." See footnote 10 in the case for an explanation of the uncertainty regarding burden of proof of mitigation of damages, with cites to various sources.

Nutt v. Florio, 75 Mass. App. Ct. 482 (2009)
Liability for bite by tenant's dog. A dog bite victim sued the landlord of the owner of the dog, a pit bull. The court stated that the pit bull is a breed "commonly known to be aggressive." "While the defendants may not be held strictly liable by virtue of Tiny's breed, knowledge of that breed and its propensities may properly be a factor to be considered in determining whether the defendants were negligent under common-law principles."

Phillips v. Equity Residential Management, L.L.C., 478 Mass. 251 (2017) 
Triple damages apply to deductions wrongfully made from a deposit, not to defects in the statement of damages, such as the failure to include the required statutory pains and penalties wording in the statement.

South Boston Elderly Residences, Inc. v. Moynahan, 91 Mass. App. Ct. 455 (2017) 
In a warranty of habitability case, the Appeals Court, applied the tort principle that “the defendant must take its plaintiff as it finds him or her” and held that where material breach of the warranty of habitability occurred, a tenant’s special sensitivity to a condition in the apartment may be considered in the determination of the “diminished value to him” of the premises due to its defective condition.  The Appeals Court also held that a lease which permits a landlord a right to access an apartment for purposes of inspection and repair does not create blanket authority for the landlord to enter at any time without the tenant’s permission in derogation of a tenant’s quiet enjoyment rights under statute.

Worcester v. College Hill Properties, LLC, 465 Mass. 134 (2013)
Lodging houses. An apartment rented to 4 college students to share is not a lodging house.
