The Tenant Retaliation Defense and What Every Massachusetts Landlord Needs to Know

If you are a Massachusetts landlord who has filed or is considering filing a Massachusetts eviction against a tenant, one of the most serious defenses you may encounter in court is a claim of retaliation. Under Massachusetts law, a tenant who believes that a landlord is pursuing an eviction (or taking other adverse action) because the tenant exercised a legally protected right can raise retaliation as both a defense to the eviction and as a counterclaim for money damages. For Massachusetts landlords who have had no problems with a tenancy until a tenant suddenly reports a housing code violation or joins a tenant organization, the appearance of a retaliation claim in an eviction case can be jarring, frustrating, and, if handled poorly, financially devastating.

This article is written from the perspective of a Massachusetts landlord who is concerned about the retaliation defense and wants to understand how it works, what the law requires, what the courts have said, and most importantly, what a landlord can do to protect against a retaliation claim in a Massachusetts eviction case.

What Is the Retaliation Defense Under Massachusetts Law?

The retaliation defense in Massachusetts eviction cases is rooted primarily in two statutes: Massachusetts General Laws Chapter 186, Section 18, and Massachusetts General Laws Chapter 239, Section 2A. Together, these two provisions create powerful protections for tenants who have engaged in certain activities that Massachusetts law considers protected.

Under Massachusetts General Laws Chapter 186, Section 18, it is unlawful for a landlord to take reprisals against a tenant for any of the following activities:

1. Reporting to the local board of health or any other governmental agency a violation or a suspected violation of any health or building code, or any other state or local law or regulation governing residential premises.
2. Commencing, proceeding with, or obtaining relief in any judicial or administrative action the purpose of which is to enforce any federal, state, or local law governing residential premises.
3. Reporting or complaining of such a violation or suspected violation to the landlord or the landlord’s agent.
4. Organizing or joining a tenants’ union or similar tenant organization.
5. Exercising rights pursuant to certain provisions of Massachusetts law governing utility shutoffs.

The statute also provides that if a landlord sends a tenant a Notice to Quit (other than for nonpayment of rent), increases rent, or substantially alters the terms of the tenancy within six months after the tenant engaged in any of these protected activities, a legal presumption arises that the landlord’s action was retaliatory. This six-month window is critical. As a Massachusetts landlord, you need to understand that any adverse action you take against a tenant within six months of that tenant exercising a protected right will trigger this presumption automatically.

Once the presumption of retaliation is established, the burden shifts entirely to the landlord. To overcome the presumption, the landlord must prove by clear and convincing evidence (a high legal standard) that the action taken was not a reprisal, that there was a sufficient independent justification for it, and that the landlord would have taken the same action in the same manner and at the same time regardless of the tenant’s protected activity. That is an extremely difficult burden to meet, particularly when the timing of the landlord’s action closely follows the tenant’s complaint.

What Actions Can a Tenant Take as Protected Activities?

It is important for a Massachusetts landlord to understand exactly how broad the category of protected tenant activities is under Massachusetts law. Many landlords are surprised to discover that protected activities go well beyond simply filing a formal lawsuit. The following are among the most common protected activities that Massachusetts tenants invoke to support a retaliation defense in an eviction case.

Reporting Housing Code Violations

When a Massachusetts tenant reports a housing code violation to the local board of health, to a building inspector, or to any other governmental authority with oversight of residential premises, that act is protected under Massachusetts General Laws Chapter 186, Section 18. This is one of the most common triggers for a retaliation defense in a Massachusetts eviction case. A landlord who serves a Notice to Quit within six months of a health inspection or a board of health complaint will face the legal presumption that the eviction is retaliatory, regardless of the stated reason for the notice.

Complaining to the Landlord Directly

Perhaps most surprising to many Massachusetts landlords is the fact that a tenant does not have to file a formal complaint with a government agency to earn protection under the retaliation statute. Simply reporting or complaining of a housing code violation or a suspected violation directly to the landlord or the landlord’s agent is a protected activity. This means that even an informal written message from a tenant saying that the heat is not working properly, or that there are mice in the unit, can, if followed within six months by a Notice to Quit or a rent increase, give rise to a presumption of retaliation.

Filing or Participating in Legal Actions

A tenant who commences or participates in a legal proceeding to enforce housing laws, or who files a complaint with any administrative agency, is also engaged in a protected activity. This includes filing a complaint with the Massachusetts Commission Against Discrimination, seeking a court order to compel repairs, or participating as a witness in a housing code enforcement proceeding.

Organizing or Joining a Tenants’ Union

Massachusetts law specifically protects tenants who organize or join a tenants’ union or similar tenant organization. A Massachusetts landlord who serves a Notice to Quit on a tenant shortly after that tenant becomes active in a tenant organization or participates in collective tenant activity will face a presumption of retaliation.

Two Massachusetts Cases Where the Tenant Prevailed on a Retaliation Defense

Massachusetts courts have taken the retaliation defense seriously and have ruled in favor of tenants in a number of cases. The following two examples illustrate how Massachusetts courts apply the retaliation statute and the kinds of circumstances that lead to outcomes favoring the tenant.

Campbell v. Abdulla (Massachusetts Appeals Court, 2025)

One of the most significant and recent Massachusetts decisions on the retaliation defense is Campbell v. Abdulla (2025), decided by the Massachusetts Appeals Court. This case involved a tenant who had lived in her Haverhill apartment for several years. After noticing signs of a rodent infestation in the unit, she notified her landlord of the problem. When the landlord did not address it, the tenant reported the rodent activity and other housing conditions to the Board of Health. A health inspection confirmed the violations, and the Board issued a formal notice of violations against the landlord.

Approximately one month after the Board issued its notice, the landlord served the tenant and her family with a Notice to Quit for cause, citing lease violations. The tenant raised retaliation as a defense in the Housing Court eviction proceedings that followed. At the trial level, the Housing Court judge acknowledged that the retaliation defense was facially viable given the close timing between the board of health complaint and the Notice to Quit. However, the trial judge ruled that the retaliation defense was only available in cases involving nonpayment of rent or no-fault terminations, and not in for-cause eviction cases. The landlord was awarded possession.

The Massachusetts Appeals Court reversed that decision. The Appeals Court held that the retaliation defense under Massachusetts General Laws Chapter 239, Section 2A applies to all Summary Process eviction cases, including for-cause evictions. Because the Notice to Quit followed the board of health complaint by only one month, well within the six-month window, the legal presumption of retaliation arose. The Appeals Court vacated the judgment in favor of the landlord and remanded the case for further proceedings in which the landlord would be required to meet the burden of proving by clear and convincing evidence that the eviction was not retaliatory.

The message for Massachusetts landlords from Campbell v. Abdulla is powerful and practical: it does not matter what reason a landlord gives for an eviction if the timing of the Notice to Quit falls within six months of a tenant’s protected activity. The retaliation defense is available to tenants in all types of Massachusetts eviction cases, not just those involving nonpayment of rent.

Genovevo v. Gallagher (Hampden Housing Court, 1995)

An earlier Massachusetts case that illustrates how courts analyze the retaliation defense in the context of a landlord’s longstanding awareness of a lease violation is Genovevo v. Gallagher, decided in the Hampden Housing Court in 1995. In Genovevo, the landlord sought to evict the tenant for a lease violation that had existed for some time prior to the eviction. The landlord had been aware of the lease violation but did not take steps to evict the tenant until after the tenant engaged in protected activity by making complaints about the conditions of the premises.

The Housing Court ruled in favor of the tenant, finding that the landlord’s awareness of and tolerance for the lease violation for an extended period of time, combined with the timing of the eviction following the tenant’s protected complaint, made it extremely difficult for the landlord to rebut the presumption of retaliation. The court’s reasoning reflected a principle that has been consistently applied in Massachusetts landlord-tenant law: if a landlord had a legitimate basis for eviction that predated the tenant’s protected activity but did not act on it until after the tenant complained, the courts will view the timing of the eviction with deep suspicion.

Genovevo v. Gallagher is particularly instructive for Massachusetts landlords because it addresses situations where the landlord genuinely believes they have a legitimate non-retaliatory reason to evict, but where that reason existed long before the eviction was actually filed. Courts in Massachusetts have repeatedly noted in this context that a landlord who could have evicted a tenant for a lease violation at any time but chose to act only after the tenant made a health complaint faces an uphill battle in convincing the court that the eviction was not retaliatory.

What Are the Damages a Massachusetts Landlord Can Face If Found to Have Retaliated?

Massachusetts landlords who are found to have retaliated against a tenant face significant financial exposure. Under Massachusetts General Laws Chapter 186, Section 18, a tenant who prevails on a retaliation claim is entitled to recover damages in the amount of not less than one month’s rent and not more than three months’ rent, or the actual damages suffered by the tenant, whichever is greater. In addition, the tenant is entitled to recover reasonable attorney’s fees and court costs. In cases involving serious or intentional retaliation, courts may also have the discretion to award additional remedies.

Beyond the financial exposure on the retaliation counterclaim itself, a Massachusetts landlord who loses an eviction case because of a retaliation defense also loses possession, which means the tenant remains in the unit. The landlord has not only failed to recover possession but has potentially paid the tenant money damages and attorney’s fees in the process. This outcome is precisely why understanding and protecting against the retaliation defense is so important for Massachusetts landlords before they initiate an eviction.

What Should a Massachusetts Landlord Do to Protect Against a Retaliation Claim?

The good news for Massachusetts landlords is that the retaliation defense, while powerful, is rebuttable. A landlord who has acted in good faith and who has maintained good documentation of legitimate reasons for an eviction that are independent of any tenant complaint can overcome the presumption of retaliation. The following are practical steps that Massachusetts landlords should take to protect themselves.

Document Everything Before Any Complaint Is Made

The most important protection a Massachusetts landlord can have against a retaliation claim is a contemporaneous record of lease violations, nonpayment of rent, or other legitimate grounds for eviction that predates any tenant complaint. If a tenant is chronically late with rent, keep written records of every late payment. If a tenant has violated a lease provision, document that violation in writing as soon as it comes to your attention. Do not wait. A Massachusetts landlord who has a paper trail of legitimate grounds for eviction that clearly precedes a tenant’s protected activity is in a far stronger position to rebut the presumption of retaliation.

Be Careful About Timing

Massachusetts landlords should be extremely cautious about the timing of any Notice to Quit, rent increase, or other adverse action in relation to any tenant complaint. If a tenant has recently reported a housing code violation, written to the landlord about conditions in the unit, or filed any complaint with a government agency, a Massachusetts landlord should consult with an attorney before taking any action that could be perceived as retaliatory. Even a legitimate eviction for genuine lease violations can be derailed if the timing of the Notice to Quit falls within the six-month window following the tenant’s protected activity.

Address Housing Code Issues Promptly

One of the best defenses against a retaliation claim is a landlord who can demonstrate a consistent history of responsibly maintaining the property. If a tenant reports a housing code violation, address it promptly and document your response in writing. A Massachusetts landlord who responds quickly and professionally to tenant complaints and who repairs code violations in a timely manner is not only fulfilling their legal obligations but is also building the kind of factual record that makes a retaliation claim harder to sustain.

Consult an Attorney Before Filing an Eviction

Given how serious and far-reaching the retaliation defense is under Massachusetts law, any Massachusetts landlord who is considering filing an eviction against a tenant who has made complaints about the property, reported code violations, or engaged in any other protected activity should consult with a licensed Massachusetts attorney before serving a Notice to Quit. An attorney can review the timeline of events, evaluate the strength of the retaliation defense that the tenant is likely to raise, and advise on whether and how to proceed with the eviction in a way that maximizes the likelihood of success.

Conclusion

The tenant retaliation defense is one of the most consequential and commonly raised defenses in Massachusetts eviction cases. Under Massachusetts General Laws Chapter 186, Section 18, and Massachusetts General Laws Chapter 239, Section 2A, Massachusetts tenants who have engaged in protected activities such as reporting housing code violations, making complaints to government agencies, or joining tenant organizations are entitled to a legal presumption of retaliation if a landlord takes adverse action against them within six months of that protected activity.

As the decisions in Campbell v. Abdulla and Genovevo v. Gallagher illustrate, Massachusetts courts apply the retaliation statute broadly and take the tenant’s claims seriously. For a Massachusetts landlord, the stakes of ignoring or underestimating the retaliation defense are high: a finding of retaliation in a Massachusetts eviction case can result in loss of possession, money damages, and an order to pay the tenant’s attorney’s fees.

The best protection is preparation: thorough documentation, careful attention to timing, prompt attention to housing conditions, and consultation with an experienced Massachusetts landlord-tenant attorney before filing an eviction. If you are a Massachusetts landlord who is concerned that a tenant may raise a retaliation defense in an upcoming eviction, speak with a qualified Massachusetts attorney who handles landlord and tenant matters before you take any action.
