Yes, and there is no limit on the amount. Massachusetts has had no rent control anywhere in the state since 1994, so a landlord can raise the rent by any figure the market will bear.
What you do have is procedure. There are rules about how much warning you're owed, rules about when in your tenancy an increase can happen at all, and a specific protection if the increase followed a complaint you made. Those are worth knowing precisely, because they're the parts you can actually act on.
No, there's no cap on the increase
Rent control was eliminated statewide by a 1994 ballot initiative, and the ban applies to every city and town. No municipality in Massachusetts can adopt its own rent control or rent stabilization scheme, which is why you'll see the subject debated periodically without anything changing.
The practical consequence is that the size of an increase is not, by itself, a legal issue. A steep increase on a long-term tenant, with no improvements to the unit, is still lawful.
It can be a large number, and it can price someone out of a neighborhood they have lived in for years. None of that changes the legal position. Anyone telling you a percentage is "too high to be legal" in Massachusetts is mistaken.
So the useful question is whether the landlord followed the rules that do exist, not whether the amount is allowed.
What notice you're owed
| Your situation | What applies |
|---|---|
| Fixed-term lease, mid-term | No increase during the term. The lease is the agreement, and it sets the rent until it ends |
| Fixed-term lease, at renewal | The renewal is a new agreement. You can accept it, try to negotiate, or decline and move |
| Tenancy at will | At least 30 days' notice, or one full rental period, whichever is longer. The notice ends your current tenancy and offers a new one at the higher rent, so refusing it is also an option |
| A new "fee" rather than a rent increase | Not the same thing. Massachusetts limits what a landlord may require before a tenancy starts |
A tenancy at will is a rental with no fixed end date. Either side can end it with proper notice, and no lease term is running. That is the distinction the table turns on, and it isn't always obvious from your paperwork.
Which row you're in depends on what kind of tenancy you actually have. If you signed a lease for a fixed period and it has since expired without a new one being signed, your situation may have changed in ways worth checking.
One thing a notice does not do is raise your rent by itself. If you hold a tenancy at will, a rent-increase notice ends your current tenancy and offers you a new one at the higher figure. You can accept it, try to negotiate, or refuse it and carry on paying the rent you already pay. Refusing an increase is not the same as failing to pay rent, so it isn't grounds for a non-payment eviction; ending the tenancy is a separate step the landlord would have to take.
They can't raise it mid-lease
If you hold a fixed-term lease, the rent stated in it is the rent for that term. A landlord cannot raise it in month five of a twelve-month lease because the market moved.
That means increases arrive at renewal, and a renewal is a genuinely new agreement rather than a continuation. You are not obliged to sign it. Your options at that point are to accept, to try to negotiate, or to decline and move.
If you complained first, the timing matters
A rent increase or other change to your tenancy that follows within six months of a housing complaint can be presumed retaliatory under Massachusetts law, which is one of the only real levers tenants have in a state with no cap on rent increases.
Under M.G.L. c.186 §18, if you receive a notice of a rent increase — or any substantial alteration in the terms of your tenancy — within six months of reporting a sanitary code violation or other housing-law violation, or of taking part in a tenants' union, that creates a rebuttable presumption of reprisal.
The presumption can be rebutted only by clear and convincing evidence that the action was not a reprisal and that the landlord had sufficient independent justification for it.
Damages run from a minimum of one month's rent up to three months' rent or actual damages, whichever is greater, plus attorney's fees. This protection cannot be waived in a lease.
It's worth being clear about what a rebuttable presumption actually does, because the phrase does a lot of work. Normally, someone alleging retaliation would have to prove the landlord's motive — which is close to impossible. The presumption flips that. Once the six-month timing is established, the landlord has to prove the increase wasn't retaliation, to a demanding standard, with an independent justification for it.
That doesn't make the increase automatically unlawful, and it doesn't mean you have a case. What it means is that the timing is legally significant, and that a landlord who raised your rent five weeks after you called the inspector is in a materially different position than one who raised it out of the blue.
Two practical notes. Write down the dates — when you complained, to whom, and when the notice arrived. And note that because §18 can't be waived, a lease clause purporting to sign the protection away has no effect; our guide to lease clauses that aren't enforceable in Massachusetts covers how that works more broadly.
What to do when the notice arrives
Five things to check, roughly in the order they matter most.
- Check the notice period against your tenancy type. If you're a tenant at will and got less than the required warning, the increase doesn't take effect on the date they've claimed. That's not a permanent reprieve, but it's real time.
- Check the date against anything you reported. If you complained about conditions in the last six months, the six-month retaliation presumption may apply.
- Ask what's driving it. Not as a negotiation gambit, just as information. A landlord passing on a tax or insurance increase is in a different conversation from one testing the market, and the answer tells you how much room there is.
- Try to negotiate. Sometimes it works, particularly with smaller landlords who value a reliable tenant over a vacancy. We've covered the tactics separately in how to negotiate your rent and in negotiating with a small Somerville landlord.
- Decide whether to move, and do it early if so. This is the unglamorous one and often the right answer. If the new rent doesn't work, the worst outcome is discovering that in late August when nothing is left. Deciding in month ten of your lease gives you the whole market; deciding in month twelve gives you whatever's unrented.
If you do end up moving, the move-in cost is the thing that decides how far your budget stretches. Spot Easy lists Boston apartments with no broker fee on partner units and no admin fees in the fine print.

When a fee isn't rent
Sometimes what arrives at renewal isn't a rent increase at all — it's a new charge with an administrative-sounding name attached to the same rent.
That's a different question, and a more promising one. Massachusetts limits what a landlord may require at all, and those limits get enforced: in July 2026 the Attorney General's office settled with a Boston management company over fees dressed up as lease-renewal and new-lease charges. Our guide to what a landlord can legally charge covers the full list.
If your renewal comes with a new fee rather than a higher rent, it's worth asking in writing what the charge is for before paying it. Who handles which landlord problem covers where fee complaints go.
Where this stops being general advice
This page describes the rules. It can't tell you how they apply to your tenancy, and a few of the questions that matter most are genuinely fact-specific:
- What kind of tenancy you actually have. Fixed-term, at-will and month-to-month arrangements aren't always distinguishable from the paperwork, and the answer decides your notice period.
- Whether a particular increase was retaliatory. The presumption is about timing; whether it holds up depends on everything else.
- What happens if you can't pay and stay past the notice. That's the beginning of an eviction question and needs advice quickly.
MassLegalHelp and Greater Boston Legal Services both cover this ground for free, and the Attorney General's consumer line handles fee complaints.
Frequently asked questions
Is there a limit on how much my landlord can raise my rent in Massachusetts? No. Rent control has been banned statewide since 1994, and no city or town may impose one. There is no cap on the amount of an increase.
How much notice does a landlord have to give for a rent increase? For a tenancy at will, at least 30 days or one full rental period, whichever is longer. That notice ends the old tenancy and offers a new one at the higher rent, so you can also refuse it and keep paying the rent you already pay. Under a fixed-term lease, the rent can't be raised during the term at all.
Can my landlord raise the rent in the middle of my lease? No. A fixed-term lease sets the rent for its term. Increases come at renewal.
My rent went up right after I complained about repairs. Is that legal? It may be retaliation. An increase within six months of reporting a code violation creates a rebuttable presumption of reprisal, which the landlord must overcome with clear and convincing evidence.
What are the penalties if a rent increase is retaliatory? The statute provides for at least one month's rent, up to three months' rent or actual damages, whichever is greater, plus attorney's fees.
Can my lease say I give up retaliation protection? No. That protection cannot be waived in a lease or rental agreement.
They added an amenity fee instead of raising rent. Is that allowed? It's a different question. What a landlord may require is limited by statute, and the Attorney General has enforced against renewal-type fees. Ask in writing what it's for.
Do I have to sign the renewal? No. A renewal is a new agreement. You can accept it, negotiate, or decline and move.
How we sourced this
The statewide ban on rent control dates to the 1994 ballot initiative, and the absence of any cap on increases follows from it. The notice rule for ending a tenancy at will comes from Massachusetts General Laws Chapter 186, Section 12, which for rent payable monthly requires notice equal to one full rental period or 30 days, whichever is longer. The retaliation provisions are separate, and come from Chapter 186, Section 18, which sets out the six-month presumption, the clear-and-convincing rebuttal standard, the damages range, and the ban on waiving it.
The limits on what a landlord may require are in M.G.L. c.186 §15B. The enforcement action over renewal fees was announced by the Massachusetts Attorney General's office.
Which notice period applies to you depends on your tenancy type, which is a legal question rather than a self-assessment. Check with a housing attorney or legal aid if it isn't clear.
