Massachusetts Tenant Rights 101: The Complete Starter Guide
Every Massachusetts renter's rights, in one place: tenancy types, deposits, habitability, eviction protections, and where to go for help — each one sourced to the actual law.
A complete starting point for Massachusetts tenant rights: the difference between a lease and a tenancy at will, what a landlord must legally provide, what they're barred from doing (like lockouts and retaliation), and exactly which Massachusetts law backs each right.
BLUF: The Rights Every MA Tenant Should Know
📋First: What Kind of Tenancy Do You Have?
Massachusetts recognizes two basic residential tenancy types, and which one you have changes your notice rights:
Tenancy at will — no fixed end date, typically month-to-month (whether or not there's a written agreement). Either side can end it with written notice equal to the rental period or 30 days, whichever is longer (M.G.L. c. 186 §12).
Tenancy for a fixed term (a lease) — runs to the date stated in the lease and doesn't require notice to end on schedule; if you or the landlord want to end it early, the lease terms and general contract law govern, not the tenancy-at-will notice rules.
Either way, ending a tenancy requires a notice to quit — a document that terminates the tenancy — which is a completely separate step from an eviction filing. Post #5 in this series covers that process end to end.
🔧Your Landlord's Core Obligations
| Right | What it means | Statute |
|---|---|---|
Habitable unit | Working heat, hot water, plumbing, no pest infestation, sound structure, functioning smoke/CO alarms | 105 CMR 410 (State Sanitary Code) |
Security deposit rules | Max 1 month's rent, held in a MA interest-bearing account, itemized receipts, returned within 30 days of tenancy end | M.G.L. c. 186 §15B |
Lead paint disclosure & remediation | Must disclose known lead paint in pre-1978 buildings and delead if a child under 6 lives there | M.G.L. c. 111 §§189A–199B |
Quiet enjoyment | Can't cut off utilities, change locks, or otherwise interfere with your ability to live in the unit | M.G.L. c. 186 §14 |
No retaliation | Can't raise rent, end your tenancy, or otherwise punish you within 6 months of you reporting a violation or asserting a right | M.G.L. c. 186 §18 |
No discrimination | Can't refuse to rent, or treat you worse, based on race, disability, familial status, source of income (e.g., Section 8), and other protected classes | M.G.L. c. 151B |
🚫What Your Landlord Cannot Legally Do
- •Lock you out or remove your belongings without a court order. "Self-help eviction" — changing locks, shutting off utilities, or physically removing you — is illegal, even if you owe rent. It's punishable as a crime and gives you a civil claim for three months' rent or actual damages, whichever is greater, plus attorney's fees (M.G.L. c. 186 §14; c. 184 §18).
- •Retaliate against you for exercising your rights. Reporting a code violation, joining a tenant union, or filing a fair-housing complaint, followed by a rent increase or termination notice within 6 months, is presumed retaliatory by law (c. 186 §18).
- •Waive your statutory rights in the lease. Clauses that try to waive your right to withhold rent for code violations, your security-deposit protections, or your anti-retaliation protections are void, no matter what you signed (c. 186 §§15B, 18).
- •Refuse to rent to you because you have a housing voucher, kids, or a disability. Source-of-income, familial-status, and disability discrimination are all illegal under M.G.L. c. 151B — see our fair housing guide later in this series.
