Selected case law

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."

City of 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.
