What is a retaliatory eviction under Massachusetts law?

Under M.G.L. c. 186, § 18 and M.G.L. c. 239, § 2A, a retaliatory eviction occurs when a landlord serves a Notice to Quit, raises rent, or materially alters tenancy terms in response to a tenant exercising a legally protected right. The statutes prohibit any reprisal — including threats — by a landlord, property manager, or agent against a tenant for engaging in protected activity. A tenant may raise retaliation as a complete defense in a Summary Process eviction case, potentially defeating the eviction entirely.

What tenant activities are protected from landlord retaliation in Massachusetts?

Protected activities under M.G.L. c. 186, § 18 and M.G.L. c. 239, § 2A include: reporting housing or sanitary code violations to the Board of Health or any regulatory agency; commencing or participating in legal or administrative proceedings; organizing or joining a tenants' union; withholding rent due to substandard habitability conditions in accordance with Massachusetts law; and seeking domestic violence, sexual assault, or stalking protections including restraining orders under M.G.L. c. 209A or harassment prevention orders under M.G.L. c. 258E.

What is the six-month presumption of retaliation in Massachusetts?

Under M.G.L. c. 186, § 18, if a landlord serves a notice of termination, raises rent, or makes a substantial change to tenancy terms within six months of a tenant engaging in protected activity, the landlord's action is legally presumed to be retaliatory. The burden then shifts to the landlord to prove by clear and convincing evidence — one of the highest standards in civil law — that the action was not retaliatory and would have been taken in the same manner and at the same time regardless of the tenant's protected conduct.

Can a Massachusetts landlord be found liable for retaliation in a nonpayment of rent eviction?

Yes. While M.G.L. c. 186, § 18 provides that a Notice to Quit for nonpayment alone does not trigger the retaliation presumption under that section, M.G.L. c. 239, § 2A makes retaliation an available defense in all Summary Process cases, including nonpayment evictions. A landlord who begins strict enforcement of rent payment immediately after a tenant's Board of Health complaint — particularly with no prior documented pattern of enforcement — may still face a viable retaliation defense.

What damages can a Massachusetts landlord face for retaliatory eviction?

Under M.G.L. c. 186, § 18, a landlord found liable for retaliation faces damages of no less than one month's rent and no more than three months' rent, or the tenant's actual damages, whichever is greater, plus court costs and the tenant's reasonable attorney's fees. If the conduct was willful and knowing, additional claims under M.G.L. c. 93A (the Massachusetts Consumer Protection Act) may allow for double or treble damages on top of the base award.

How can a Massachusetts landlord protect an eviction case from a retaliation defense?

Key protections include: maintaining a contemporaneous written record of the eviction ground that predates any protected tenant activity; never responding to a Board of Health complaint, legal aid letter, or tenants' union notice with immediate adverse action; bringing all outstanding code violations and maintenance issues into compliance before filing; and consulting an experienced Massachusetts eviction attorney before serving any notice. A documented eviction ground that clearly predates the tenant's protected activity is the strongest available rebuttal to a retaliation presumption.

Can a Massachusetts landlord evict a tenant who called the Board of Health?

A landlord may have legitimate grounds to evict a tenant who has called the Board of Health, but the timing is critical. Serving a Notice to Quit within six months of the Board of Health complaint creates a statutory presumption of retaliation under M.G.L. c. 186, § 18 that the landlord must rebut by clear and convincing evidence. A landlord with a documented, pre-existing eviction ground — such as months of prior rent arrears or written lease violation warnings — is in a far stronger position to overcome this presumption than one without such a record.
