Massachusetts state law (Mass. Ann. Laws ch. 239 § 2A; ch. 186 § 18) prohibits landlords from retaliating against tenants.
It is illegal for a landlord to retaliate against a tenant in Massachusetts who has exercised a legal right, including:
Massachusetts law applies when a retaliatory eviction follows a court case or administrative hearing concerning the tenant’s underlying complaint, membership in a tenant organization, or exercise of a legal right. In this situation, a tenant may claim the benefit of the antiretaliation presumption only if the eviction falls within six months of the final determination of the court case or administrative hearing.
For advice on how to respond to—and prove—retaliation, see the article Landlord Retaliation.

Also, check your local housing ordinances, particularly if you are covered by rent control, for any city or county rules that protect tenants from landlord retaliation. To find yours, call your mayor or city manager’s office or check your city or county website.
