Rent Increases in Boston
Boston has no rent cap. But state law still sets strict rules for how and when your landlord can raise your rent. This page explains those rules, your choices, and what happens in court.
-
No law caps rent amounts in Boston. Your landlord can propose any increase. Massachusetts law bans rent control in every city and town as decided by statewide ballot in 1994. Therefore, Boston cannot set a cap.

If you have a lease, your rent stays the same until the lease term ends. Your landlord can raise rent during the lease only if the lease has a tax escalator clause.

A tax escalator clause makes you pay part of a property tax increase during the lease. Massachusetts law sets 3 conditions: the clause must say you pay only your unit's share of the tax increase, it must state the exact percentage you pay, and it must promise you a share of any tax refund your landlord receives.

A tax escalator clause that breaks any of these conditions is not valid. The court will not enforce it. If you paid more than your unit's share, your landlord must return the extra money. The law adds interest of 5% per year. 5% of a $200 overcharge is $10 for 1 year.

If you rent month to month without a lease, you are a tenant at will. Your landlord can propose a rent increase at any time. But you must get written notice first. You must get the notice at least 30 days or 1 full rental period ahead, whichever is longer.

For a tenant at will, a valid rent increase notice does 2 things: it ends your current tenancy at the old rent and it offers you a new tenancy at the higher rent. Count the notice time from the day the notice actually reaches you.

The new rent binds you only if you agree to it. If you pay the higher rent, the court can treat the payment as your agreement. Decide before you pay.

If you accept the higher rent, your landlord can ask you to add the difference to your security deposit and last month's rent. The deposit still cannot be more than 1 month of the new rent.

You can refuse the increase and stay in your home. Keep paying the old rent on time, and keep receipts. Refusing the increase is not the same as not paying rent. So your landlord cannot use the 14-day nonpayment notice against you. To evict, the landlord must send a 30-day notice to quit instead. A notice to quit is a letter that ends your tenancy but does not itself force you out.

A notice does not move you out. Only a court can order you to leave. Your landlord cannot change the locks or take your belongings. The court case is called summary process. In that case, you can raise defenses. A defective or missing notice is a defense that can end the case.

Boston adds a local rule. A landlord who ends a tenancy must also give you a City form called the "Notice of Tenants' Rights and Resources." It must come with the notice to quit or the notice of non-renewal. If you did not get the form, you can report the landlord to the City.

Your landlord cannot raise your rent to punish you for using your legal rights. Protected acts include reporting unsafe conditions, complaining to your landlord in writing, going to court, and joining a tenants union. In Boston, reports to the City's housing inspection office are protected too.

Timing protects you. Suppose your landlord raises rent or sends a notice to quit within 6 months after your protected act. The court then assumes the landlord acted to punish you. This protection works in your own lawsuit and as a defense against eviction. Your landlord can defeat that assumption only with clear and convincing proof.

If the court finds the increase was punishment, your landlord owes you money. You get at least 1 month of rent and up to 3 months of rent, or your actual losses if greater. Your landlord also pays your court costs and a reasonable lawyer fee. A lease cannot make you give up this protection. The court will not enforce a lease term that tries.
