Landlord Retaliation in Massachusetts: The Six-Month Presumption and How to Use It

If you reported bad conditions, complained in writing to your landlord, took the landlord to court, or joined a tenants’ group, and within six months you got a notice to quit, a rent increase, or a change in your terms, Massachusetts law presumes the landlord is retaliating. The landlord can overcome that presumption only with clear and convincing evidence that the action was not retaliation and would have happened anyway (G.L. c. 186, § 18). Retaliation is both a defense to eviction (G.L. c. 239, § 2A) and a claim for one to three months’ rent plus attorney’s fees. Section 18 does not presume retaliation from a notice to quit for nonpayment, but the § 2A eviction defense applies in nonpayment and for-cause cases alike. Here is how tenants use it in Housing Court.

What counts as protected activity

The statute lists specific activities. If you did one of them, you are protected (G.L. c. 186, § 18):

• Reporting a violation to a public agency. Calling the board of health, or in Boston the Inspectional Services Department, about a health or building code violation or a suspected one.
• Complaining in writing to the landlord. A text or email about a violation or suspected violation counts. A phone call does not, which is why every complaint should be in writing.
• Taking legal action. Commencing, proceeding with, or obtaining relief in any court or administrative action to enforce a law that regulates residential premises. A counterclaim in an eviction case counts.
• Organizing or joining a tenants’ union or similar organization.
• Exercising utility rights under G.L. c. 164, § 124D, or paying rent to a condominium association under G.L. c. 183A, § 6(c).

Chapter 239, § 2A adds protection for a tenant, co-tenant, or household member who seeks a restraining order, uses the tenant protections for victims of domestic violence, sexual assault, or stalking, or reports such an incident to police.

If someone else took one of these steps on your behalf, or about your building, the six-month window runs from their action too (G.L. c. 186, § 18).

Raising bad conditions in an eviction case is protected as well. When a tenant invokes the rent withholding statute, G.L. c. 239, § 8A, the statute expressly applies § 18 to that tenant. See our guide to withholding rent in Massachusetts.

What counts as retaliation

Section 18 names three landlord actions that trigger the presumption when they arrive within six months of protected activity:

1. A notice of termination of tenancy, except for nonpayment of rent.
2. A notice of rent increase.
3. A notice of any substantial alteration in the terms of tenancy.

Section 2A, the eviction defense, covers filing a summary process case, sending the notice to quit it is based on, or sending a notice or doing any act whose purpose is to materially alter the terms of the tenancy (G.L. c. 239, § 2A).

Beyond the presumption, § 18 makes a landlord liable for threatening or taking reprisals of any kind. A landlord who cuts a service, refuses a repair, or starts harassing you after you complain can be liable even if the conduct is not one of the three listed notices. You just do not get the presumption; you have to prove the connection.

Shutoffs, lockouts and harassment

Some landlords skip the paperwork and retaliate by making life hard. A separate statute covers that conduct. A landlord who willfully fails to provide required heat, hot water, water, light, power or gas, who interferes with your quiet enjoyment, or who tries to regain possession by force without going to court, is liable for actual and consequential damages or three months’ rent, whichever is greater, plus a reasonable attorney’s fee (G.L. c. 186, § 14). Those damages can be set off against any rent the landlord claims.

If the retaliation takes this form, you can bring claims under both § 14 and § 18. If it is an emergency, such as no heat or a changed lock, go to Housing Court the same day. Read Locked Out or Utilities Shut Off? What Massachusetts Tenants Can Do the Same Day.

How the presumption shifts the burden

Normally a tenant claiming retaliation has to prove the landlord’s motive, which is hard. The presumption flips that.

Once you show two facts, protected activity and a listed landlord action within six months, the law presumes retaliation. The landlord must then prove by clear and convincing evidence both that the action “was not a reprisal against the tenant” and that the landlord “had sufficient independent justification for taking such action, and would have in fact taken such action, in the same manner and at the same time the action was taken,” regardless of your protected activity (G.L. c. 186, § 18; G.L. c. 239, § 2A).

It is not enough for the landlord to have a legitimate reason. The landlord has to prove the same action would have happened at the same time anyway. “I was always planning to raise the rent” needs evidence, not just testimony. A landlord who sat on a complaint for months and then sent a notice two weeks after a board of health inspection has a problem.

If the landlord’s action came more than six months after your protected activity, you can still claim retaliation, but you carry the burden of proof.

Counting the six months

Count from your protected act to the landlord’s action. Here is an example. You email your landlord about mold on March 3. The board of health inspects on March 20. You get a no-fault notice to quit on August 15. Both March dates are within six months of August 15, so the presumption applies. If the notice instead arrived on October 1, it would be more than six months after both March dates. You could still argue retaliation, but you would have to prove it.

Each protected act starts its own six months. A new written complaint, a second inspection, or a court filing can restart the window. Keep the dates.

The nonpayment exception

Section 18 carves out one notice from the presumption: a notice of termination “for nonpayment of rent.” A 14-day notice for unpaid rent sent within six months of your complaint does not carry the § 18 presumption.

The exception is narrow. It applies to a nonpayment notice, not to a rent increase or a no-fault notice that follows a rent dispute. It does not help a landlord who manufactures a nonpayment case by refusing rent, adding unlawful fees, or raising rent without proper notice and calling the shortfall “nonpayment.” Section 2A, the eviction defense, has no such carve-out: its presumption arises whether or not the case is for nonpayment (Youghal, LLC v. Entwistle, 484 Mass. 1019, 1023-1024 (2020)), though in that case the landlord rebutted it by showing it had repeatedly sued one of the tenants before when she fell behind on rent. The defense is also available in a for-cause eviction based on alleged lease violations, and G.L. c. 239, § 8A, which covers nonpayment and no-fault cases, does not limit it (Campbell v. Abdulla, 105 Mass. App. Ct. 790 (2025)).

Damages

A landlord who retaliates is liable for not less than one month’s rent and not more than three months’ rent, or your actual damages, whichever is greater, plus costs including a reasonable attorney’s fee (G.L. c. 186, § 18). A lease clause waiving these rights is void.

In an eviction case, retaliation does double duty. As a defense under c. 239, § 2A it can defeat the claim for possession. As a counterclaim under c. 186, § 18 it can produce a money judgment for you. Raise both in the written Answer.

What happens in Housing Court

If the landlord filed in a District Court, any party may transfer the case to the Housing Court (G.L. c. 185C, § 20). In the Housing Court, the report of a board of health or city housing inspector is prima facie evidence of the facts stated in it (G.L. c. 185C, § 21). That report often proves both the bad conditions and the date the landlord learned of them.

Expect the case to go first to a housing specialist for mediation. You do not have to give up a retaliation claim to settle. If the landlord offers a new lease or drops the rent increase, the agreement can say so. If the case goes to trial, bring your timeline and the documents behind each date.

If you lose a no-fault case, ask for time. In a case where the tenancy ended without fault of the tenant, the court may stay the judgment for up to six months, or up to twelve months if the household includes a person with a qualifying disability or a person 60 or older (G.L. c. 239, § 9). The court sets the terms of any stay, and it looks at whether you have made a real effort to find other housing (G.L. c. 239, § 10).

How to set yourself up to use it

1. Complain in writing, every time. Text or email the landlord and keep the message.
2. Call the board of health or inspectional services when the landlord does not fix it. Keep the inspection report.
3. Keep a timeline. The date of each complaint, each inspection, and each notice from the landlord.
4. Do not stop paying rent to make a point. Unpaid rent hands the landlord the nonpayment exception.
5. Raise retaliation in your Answer if you are sued, as a defense and a counterclaim.

Documents to gather

• Every text, email and letter you sent the landlord about conditions, with dates.
• Inspection requests, inspection reports and any orders to correct.
• Proof of tenants’ association membership or meetings.
• Court papers from any earlier case you filed, including small claims.
• The notice to quit, rent increase or new lease terms, and the envelope.
• Your rent ledger and proof of payment, to rebut any claim that you were behind.

Frequently asked questions

I complained by phone only. Am I protected?

A report to the board of health by phone is protected. A complaint to the landlord is protected only if it was in writing (G.L. c. 186, § 18). Follow up every phone call with a text or email.

My landlord says the rent increase is “market rate.” Does that beat the presumption?

Not by itself. The landlord must prove by clear and convincing evidence that the increase would have happened in the same manner and at the same time regardless of your complaint. For a rent increase, that means the landlord has to explain the amount and the timing with evidence.

Can the landlord refuse to renew my lease after I joined a tenants’ association?

A notice of termination, a notice to quit, or an eviction case filed within six months of joining a tenants’ union is presumed retaliatory (G.L. c. 186, § 18; G.L. c. 239, § 2A). If the landlord simply lets the lease run out and then sues to evict you, the filing of that case is itself a trigger for the presumption. Joining is protected whether or not the association has done anything yet.

Can I sue for retaliation even if I am not being evicted?

Yes. Section 18 makes a landlord liable for threatening or taking reprisals, not only for evictions. Damages are one to three months’ rent or your actual damages, whichever is greater, plus attorney’s fees (G.L. c. 186, § 18).

My neighbor called the inspector about our building. Am I protected?

Yes. The six-month presumption also runs from action taken by another person on your behalf or relating to the building you live in (G.L. c. 186, § 18; G.L. c. 239, § 2A).

Can my lease waive my retaliation rights?

No. Any waiver of § 18 in a lease or rental agreement is void and unenforceable (G.L. c. 186, § 18).
