Retaliatory Eviction in Massachusetts:

What Every Landlord Must Know to Protect Their Eviction Case From the Retaliation Defense

By a Massachusetts Landlord-Tenant Attorney | Gaudet Law Office

Of all the defenses available to a tenant in a Massachusetts eviction proceeding, the retaliation defense is one of the most powerful, and one of the most misunderstood by landlords. I have seen landlords with completely legitimate grounds to evict, tenants in genuine nonpayment of rent (tenants who have materially violated their leases) walk into Housing Court confident in their case, only to watch it unravel when the tenant raised retaliation under M.G.L. c. 186, Section 18 or M.G.L. c. 239, Section 2A. The case the landlord believed was about unpaid rent suddenly became a case about timing, documentation, and the landlord’s motivations.

Retaliatory eviction is not a fringe legal theory. It is a well-established, heavily litigated, and expressly statutory defense in Massachusetts landlord-tenant law. The statutes that govern it are detailed, the presumptions they create are powerful, and the damages they authorize against a landlord who is found to have retaliated against a tenant are severe. Every Landlord must be cousneled on the retaliation risk before a single notice is served, because the safest and most cost-effective time to address this issue is before the case begins, not after a retaliation claim has been raised at trial.

This article explains what retaliatory eviction is under Massachusetts law, which tenant activities are legally protected, how the statutory presumption of retaliation works, what it takes for a landlord to rebut it, what the damages exposure looks like, and (most critically) what steps every Massachusetts landlord should take to protect their eviction case from this defense before it ever becomes a problem.

The Governing Statutes: M.G.L. c. 186, Section 18 and M.G.L. c. 239, Section 2A

Retaliation law in Massachusetts is codified in two primary statutes that work in tandem. The first, M.G.L. c. 186, Section 18, prohibits a landlord from taking reprisals against a tenant for exercising legally protected rights. The second, M.G.L. c. 239, Section 2A, makes retaliation an express defense to a Summary Process eviction action (meaning a tenant may raise the landlord’s retaliatory motive directly in Housing Court to defeat the eviction entirely). Together, these two provisions create a statutory framework that exposes any Massachusetts landlord who acts, or even appears to act,out of retaliation to both eviction dismissal and significant monetary damages.

The scope of M.G.L. c. 186, Section 18 is deliberately broad. It prohibits any person — which includes the landlord, any agent of the landlord, and any property manager acting on the landlord’s behalf — from threatening or taking reprisals against a residential tenant for exercising protected rights. Crucially, the statute does not require that the landlord actually evict the tenant. Threatening to take adverse action is itself a violation. A landlord who tells a complaining tenant ‘you can leave if you do not like it here,’ or who raises the rent immediately after a code violation complaint, is potentially in violation of the anti-retaliation statute even before a Notice to Quit has ever been served.

What Activities Are Protected Under Massachusetts Retaliation Law?

The starting point for understanding the retaliation defense is knowing precisely what tenant activities the law protects. Under M.G.L. c. 186, Section 18 and M.G.L. c. 239, Section 2A, the following categories of tenant conduct are shielded from landlord retaliation:

• Reporting housing code or sanitary code violations. A tenant who contacts the local Board of Health, the city’s inspectional services department, or any other agency with regulatory authority over residential premises — to report a violation or a suspected violation of any health or building code, is engaged in protected activity. This is the most commonly invoked form of protected conduct in Massachusetts retaliation cases. A tenant who calls the Board of Health because the heat is not working, the plumbing is defective, or there is mold in the unit is exercising a legal right that the law shields from any adverse response by the landlord.
• Commencing or participating in legal or administrative proceedings. A tenant who files a complaint in court, initiates an administrative action, or seeks to enforce any federal, state, or local law or regulation governing residential premises is protected from retaliation. This includes tenants who file claims in Housing Court for breach of the warranty of habitability, tenants who pursue complaints before the Massachusetts Commission Against Discrimination, and tenants who participate in any regulatory proceeding relating to the rental property.
• Organizing or joining a tenants’ union. Under both M.G.L. c. 186, Section 18 and M.G.L. c. 239, Section 2A, a tenant who organizes, joins, or participates in a tenants’ union or similar tenant advocacy organization is explicitly protected from retaliation. A Massachusetts landlord who serves a Notice to Quit or raises the rent within months of a tenant joining a tenants’ union faces a strong statutory presumption that the action was retaliatory.
• Withholding rent due to substandard conditions. A tenant who withholds rent because conditions in the apartment violate the State Sanitary Code or constitute a breach of the implied warranty of habitability, and who does so in accordance with Massachusetts law, is engaging in protected activity. A landlord who responds to rent withholding by immediately filing for eviction, particularly without first addressing the underlying conditions, is at significant risk of having the eviction case dismissed on retaliation grounds.
• Seeking domestic violence, sexual assault, or stalking protections. M.G.L. c. 239, Section 2A, as amended by the domestic violence protection statutes, also protects tenants who seek a restraining order under M.G.L. c. 209A or a harassment prevention order under M.G.L. c. 258E, who report incidents of domestic violence, rape, sexual assault, or stalking to law enforcement, or who take any action under M.G.L. c. 186, Sections 23 through 29. A landlord who takes any adverse action against a tenant for exercising these specific rights is subject to the full force of the retaliation statutes.

The Six-Month Presumption: The Most Dangerous Trap in Massachusetts Eviction Law

The feature of Massachusetts retaliation law that most surprises (and most seriously harms) landlords who are not fully informed is the six-month rebuttable presumption established by M.G.L. c. 186, Section 18. The statute provides that if a landlord serves a notice of termination of tenancy, raises the rent, or makes any substantial alteration in the terms of the tenancy within six months after a tenant has engaged in any of the protected activities described above, that notice or action is presumed to be retaliatory.

Let that sink in. The landlord does not have to admit retaliatory intent. The tenant does not have to prove it. The mere timing of the landlord’s action, serving a Notice to Quit, raising the rent, or materially changing the terms of the lease within six months of the tenant’s protected activity, creates a legal presumption in the tenant’s favor that the court must accept unless the landlord overcomes it. The burden immediately shifts to the landlord to prove by clear and convincing evidence, one of the highest evidentiary standards in civil law, that the eviction or other adverse action was not retaliatory. Specifically, the landlord must demonstrate that they had a sufficient independent justification for their action, and that they would have taken the exact same action, in the same manner and at the same time, regardless of whether the tenant had engaged in protected activity.

It is critical to understand what this standard actually demands of a Massachusetts landlord. It is not enough to show that there was a legitimate reason to evict. The landlord must prove that the eviction would have happened in the same way, at the same time, even without the tenant’s protected conduct. A landlord who can point to months of documented rent arrears or repeated written warnings about lease violations, all predating the tenant’s protected activity, is in a strong position to rebut the presumption. A landlord who served a Notice to Quit two weeks after a Board of Health inspection, with no prior documented record of the eviction ground, is in an extraordinarily difficult position.

There is one important qualification: M.G.L. c. 186, Section 18 explicitly provides that a Notice to Quit for nonpayment of rent does not by itself trigger the retaliation presumption under that section. However, as M.G.L. c. 239, Section 2A makes clear, the retaliation defense remains available in all Summary Process cases, including nonpayment cases, where the landlord’s filing of the Summary Process action itself was retaliatory. A landlord who suddenly begins strict enforcement of rent payment after years of informal arrangements, immediately following a tenant’s Board of Health complaint, may still face a viable retaliation defense even in a nonpayment eviction.

The Consequences of a Successful Retaliation Claim: What a Massachusetts Landlord Stands to Lose

A Massachusetts landlord who is found to have retaliated against a tenant does not simply lose the eviction case. The consequences are substantially more severe than dismissal. Under M.G.L. c. 186, Section 18, a landlord found liable for retaliation is subject to 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 the costs of the suit and the tenant’s reasonable attorney’s fees. In cases where a court finds that the landlord’s retaliatory conduct was willful and knowing, additional damages under M.G.L. c. 93A, the Massachusetts Consumer Protection Act, may also be available, with the potential for double or treble damages on top of the base award.

Consider the practical arithmetic. A landlord who evicts a tenant paying $2,000 per month, if found to have done so in retaliation, could face a damages award of $6,000 in rent equivalent damages, plus the tenant’s attorney’s fees, which in a contested Housing Court case might add another $3,000 to $7,000 or more. The total exposure on a single retaliatory eviction finding can easily exceed $10,000 to $15,000 before any Chapter 93A multiplier is applied. Compared to the cost of a proper, well-documented eviction handled by an experienced Massachusetts eviction attorney from the outset, the financial case for getting this right is overwhelming.

How Massachusetts Landlords Can Protect Themselves From the Retaliation Defense

The retaliation defense is dangerous precisely because it can arise from circumstances the landlord did not create with retaliatory intent. A landlord who has a genuinely legitimate reason to evict a tenant, nonpayment, lease violation, the legitimate need to reclaim the unit, but who times the eviction poorly in relation to a tenant’s recent protected activity will find themselves facing a presumption of retaliation they had no intention of triggering. The following practices represent what every Massachusetts landlord must be advised to implement as a matter of routine property management.

Document the Eviction Ground Consistently and Contemporaneously

The most powerful tool a Massachusetts landlord has against a retaliation defense is a written record that predates the tenant’s protected activity. If a tenant has been in arrears for three months before they ever called the Board of Health, and the landlord has three months of rent ledger entries, written payment demands, and documented communications with the tenant about the arrears, the landlord can credibly argue that the eviction would have happened regardless of the Board of Health complaint. Conversely, a landlord who has no written record of the eviction ground prior to the tenant’s protected activity is in a very weak position to rebut the presumption.

Never Respond to Protected Activity With Immediate Adverse Action

A Massachusetts landlord who receives a Board of Health complaint, a legal aid demand letter, or notice that a tenant has joined a tenants’ union should treat those events as a legal signal requiring measured, documented response, not as an emotional trigger for immediate eviction. Serving a Notice to Quit within days or weeks of a tenant’s protected activity is the single fastest way to create a retaliation presumption that is almost impossible to overcome. If the landlord has legitimate grounds to evict, those grounds will still exist in six months. A brief, properly documented waiting period, combined with evidence that the eviction decision predated the protected activity, provides meaningful protection against a retaliation claim.

Address All Outstanding Maintenance and Code Compliance Issues Before Filing

A Massachusetts landlord who files a Summary Process eviction action while the rental unit has outstanding Board of Health orders, unaddressed Sanitary Code violations, or deferred repairs is handing the tenant two defenses: habitability under M.G.L. c. 239, Section 8A, and retaliation under M.G.L. c. 186, Section 18. Before any eviction is filed, an experienced Massachusetts eviction attorney will audit the condition of the property and the landlord’s maintenance history. Units with known violations should be brought into compliance before the eviction proceeds, not as a courtesy to the tenant, but as a legal strategy to remove the foundation on which a retaliation and habitability defense rests.

Consult a Massachusetts Eviction Attorney Before Serving Any Notice

As with every aspect of Massachusetts eviction practice I have discussed in this series of articles, the single most effective protection against a retaliation defense is retaining experienced legal counsel before the first notice is served. A Massachusetts eviction attorney reviewing your case will identify the protected activity risk immediately, whether the tenant has recently filed a Board of Health complaint, initiated any legal action, joined a tenants’ organization, or engaged in any other conduct that would trigger the six-month presumption. That review, conducted before the eviction is initiated, allows for a litigation strategy that either avoids the presumption entirely or builds the documented record needed to rebut it.

Do Not Let Retaliation Law Derail Your Eviction: Contact Gaudet Law Office

The Massachusetts retaliation statutes were designed to protect tenants from landlords who abuse the eviction process to silence or punish tenants for exercising their legal rights. That is a legitimate and important purpose. But these statutes also create significant legal exposure for landlords who have entirely legitimate reasons to evict, and who simply lack the documentation, the timing strategy, or the legal awareness to protect themselves from the presumption.
