Roommate Clause
in Your Lease
What it actually means, what Massachusetts law says, what's specific to Boston - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- Our Massachusetts record reviewed the official section index of M.G.L. c. 186, which runs § 1A to § 31, and found no provision on adding an occupant or roommate.
- Because that index lists section titles rather than section text, the record reports what was checked: no added-occupant rule was found, which is not the same as a survey of every section body.
- Boston's Zoning Code Article 2 defines "Family" so that a group of five or more persons enrolled as full-time undergraduates is not deemed to constitute a family.
- M.G.L. c. 186 § 16 makes void any lease term whose effect is to end the tenancy because the tenant has a child occupying the premises.
- 940 CMR 3.17 requires the owner to hand you an executed copy of a written rental agreement within 30 days of taking your signature.
Understanding the Roommate Clause
A roommate clause names who is allowed to live in your unit and what approval a new person needs. In Boston that paragraph carries most of the weight, because our Massachusetts record finds no added-occupant provision in M.G.L. c. 186 and no deadline for telling a landlord that someone has moved in.
Boston adds a rule from an unexpected direction. The limit that most often decides who may share a unit here is not a landlord-tenant law at all - it is the Zoning Code's definition of "Family," which excludes a group of five or more full-time undergraduate students.
What renters assume
Renters assume state law gives them a window to report a new roommate, and that as long as the landlord signs off, any group that can afford the rent can share the apartment.
What is actually true
Our Massachusetts record finds no notice window in M.G.L. c. 186, so the lease supplies the timing. And in Boston a landlord's yes does not answer the zoning question: the Article 2 "Family" definition excludes a group of five or more full-time undergraduates.
The metric on this chart is the deadline to notify a landlord of a new roommate, and Massachusetts carries no figure. Only two entries do - New York at 30 days to name an added occupant, and Seattle at 30 days under a city-only rule - while Texas, California, Florida, Illinois, Colorado, Arizona, Georgia, Tennessee, Pennsylvania and Oregon all show no statute. Massachusetts sits with that second group, which leaves a Boston renter without the clock a New York tenant can point to and with the lease as the document that answers the question instead.
Plain English Version
Two separate doors have to open. Your landlord controls one of them through the lease, and Boston's zoning definition of a "Family" controls the other - and a signature on the first door does nothing to the second.
Roommate Clause Example - What the Wording Looks Like in Boston, MA
The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.
Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.
REIMBURSEMENT. You must promptly reimburse us for loss, damage, or cost of repairs or service caused anywhere in the apartment community by your or any guest's or occupant's improper use or negligence. […]
Quoted from the published opinion in Churchill Forge, Inc. v. Brown, 61 S.W.3d 368 (Tex. 2001). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“REIMBURSEMENT. You must promptly”
A duty with no date attached. Our Massachusetts record supplies none either: no deadline for telling a landlord about a new occupant, and none for a landlord to answer a request to add one. Two states in this page's comparison do put a figure on it: New York's roommate statute and Seattle's ordinance each give the tenant 30 days to name the new occupant.Read the chapter as it stands today.
“cost of repairs or service”
Our Massachusetts record holds nothing that caps this sum or splits it between the people living in the unit. What it does draw is a line between kinds of housing: under G.L. c. 186 § 17, occupancy of a dwelling unit in a licensed rooming house or lodging house - not a fraternity, sorority or educational dormitory - for three consecutive months is a tenancy at will. Three months changes what that occupant holds. This paragraph is written for the other case, where the person beside you holds nothing and your signature carries it all.
“caused anywhere”
The line runs around the whole property, not your front door: a loss in the lobby sits inside it. Boston's own limit on the household is not landlord-tenant law but zoning: Article 2 of the Boston Zoning Code defines a Family as one person, or two or more people related by blood, marriage, adoption or an analogous family union occupying a dwelling unit, and provides that a group of five or more full-time undergraduate students shall not be deemed a family. In a student city that is the rule deciding who may share a flat. Zoning text gets amended, so confirm the definition as it reads today.
“or any guest's or occupant's improper use”
A guest and a live-in occupant are held to the same test here, and neither need ever have signed. Where Massachusetts names an occupant in our record it protects a status rather than judging conduct: G.L. c. 186 § 16 makes a lease term against public policy and void where its effect is to terminate the tenancy, or to let the landlord terminate it, because the tenant has a child who occupies the premises. So a household member can expose you to a charge here and still be someone your tenancy cannot be ended over.
The co-signer's defence failed. JoAnn Brown signed an apartment lease as a cotenant with her adult son. He was alleged to have started a fire that damaged the complex, the landlord sued only her, and she argued she could not be charged for damage she had not caused. The Texas Supreme Court disagreed, reversed the summary judgment she had won and held this sentence enforceable against a cotenant who was not herself negligent. The route ran through two sections. Tex. Prop. Code § 92.052(b) gives a landlord no duty to repair damage caused by the tenant, an occupant or a guest, so § 92.006(e) had no repair duty to stop the parties contracting over; and the fair-notice doctrine did not apply, because the sentence does not shift the landlord's own negligence onto the tenant. The court added that neither statute, common law nor the Restatement bars “requiring a tenant to reimburse the landlord for damages negligently caused by the tenant or one occupying the premises with the tenant's consent.” A dissent would have held the sentence unenforceable outright because it was not underlined or conspicuous, as § 92.006(e)(4) requires. This is 2001 Texas law, decided on the Texas Property Code - state-specific, and not a national rule.
One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.
Massachusetts Law on Roommate Clause
- The official section index of G.L. c. 186 runs from § 1A to § 31 and contains no provision on adding an occupant or roommate, so no state statute sets a notice deadline or a landlord response deadline.
- G.L. c. 186 § 16 provides that a lease term whose effect is to terminate the tenancy, or to let the landlord terminate it, because the tenant has a child who occupies the premises is against public policy and void.
- G.L. c. 186 § 17 provides that occupancy of a dwelling unit in a licensed rooming house or lodging house, other than a fraternity, sorority or educational dormitory, for three consecutive months constitutes a tenancy at will.
- 940 CMR 3.17 has no roommate or added-occupant rule; its rental agreement subsection requires the owner to give the tenant an executed copy of any written rental agreement within 30 days of obtaining the tenant's signature.
M.G.L. c. 186 (no added-occupant provision) - statutes change; verify the current text for your situation.
Our Massachusetts record reviewed the official section index of M.G.L. c. 186, the landlord-tenant chapter, which runs from § 1A through § 31. No provision on adding an occupant or a roommate appears in it, so no state notice deadline and no landlord response deadline turned up. Be precise about what that means: an index lists section titles, not section text, so the record says no such rule was found rather than claiming the chapter was read section by section. A rule sitting inside a section whose title does not disclose it is not ruled out.
What the record does supply is three concrete provisions worth knowing. M.G.L. c. 186 § 16 provides that a lease term whose effect is to terminate the tenancy, or to let the landlord terminate it, because the tenant has a child who occupies the premises is against public policy and void. M.G.L. c. 186 § 17 provides that occupancy of a dwelling unit in a licensed rooming or lodging house - other than a fraternity, sorority or educational dormitory - for three consecutive months constitutes a tenancy at will. And 940 CMR 3.17, which carries no roommate or added-occupant rule of its own, does require the owner to give you an executed copy of any written rental agreement within 30 days of obtaining your signature. Read the current text of these sections before you rely on any of them.
Massachusetts Tenant Protections
Three things here are worth holding onto. M.G.L. c. 186 § 16 voids a lease term whose effect is to end the tenancy because the tenant has a child occupying the premises, so an occupancy paragraph aimed at a child in the unit is unenforceable no matter how it is worded. M.G.L. c.
186 § 17 turns three consecutive months of occupancy in a licensed rooming or lodging house into a tenancy at will, which matters in a city with as much lodging-house stock as Boston, though it does not reach a fraternity, sorority or educational dormitory.
And 940 CMR 3.17 entitles you to an executed copy of your written rental agreement within 30 days of signing it - the single most useful document you can have, because where our record finds no statute the lease is what a judge reads. Confirm the current text of each before acting on it.
What's Specific to Boston
Figures are the state rule, or the stronger city ordinance where one exists. Verify the current law for your own situation before relying on it.
Boston's rule on who may live together sits in the Zoning Code rather than in landlord-tenant law. Article 2 defines "Family" as one person, or two or more persons related by blood, marriage, adoption or other analogous family union, occupying a dwelling unit and living as a single non-profit housekeeping unit - provided that a group of five or more persons enrolled as full-time undergraduate students at a post-secondary institution shall not be deemed to constitute a family. In a city this full of students, that definition is what actually decides many shared-housing questions, and no landlord signature changes it.
One caution before you rely on the wording above. An amendment to the Article 2 definitions has been adopted but is not yet reflected in the published code, so what you have just read is the version currently in the codified text and may not be the version in force. Check the current Article 2 definition with the Boston Zoning Commission or the Inspectional Services Department before you count on it. Separately, Boston Mun. Code 9-1.3(C)(1) requires all owners of private residential rental units, including condominium units, to register with the Inspectional Services Department by July 1 each year. Our record finds no Boston ordinance creating a right to add a roommate or a deadline for notifying the landlord.
Our Massachusetts record finds no deadline of its own, so a written process with a timeline is the only clock you get - and the landlord is held to it.
940 CMR 3.17 requires the owner to give you an executed copy of a written rental agreement within 30 days of your signature. Ask for it before you argue about what it says.
Boston's Zoning Code Article 2 provides that a group of five or more full-time undergraduate students is not deemed a family. Confirm the current definition before anyone signs a sublease.
M.G.L. c. 186 § 16 voids a lease term whose effect is to end the tenancy because the tenant has a child occupying the premises. Question any wording that does that.

Red Flags to Watch Out For
-
Approval required, no reply deadline
Consent language with no response window. Our Massachusetts record finds no backstop deadline, so a request can sit unanswered unless the lease sets a date.
-
A term that targets a child in the unit
M.G.L. c. 186 § 16 makes void a lease term whose effect is to terminate the tenancy because the tenant has a child occupying the premises. That wording is unenforceable however it is dressed up.
-
No executed copy ever handed over
940 CMR 3.17 requires an executed copy of a written rental agreement within 30 days of your signature. Without it you are arguing about a document you cannot quote.
-
A fifth undergraduate on the lease
Boston's Zoning Code Article 2 provides that five or more full-time undergraduate students are not deemed a family. A landlord's approval does not resolve a zoning definition.
-
Guest converts to occupant after X nights
A night count that turns a partner staying over into a lease violation. Our Massachusetts record supplies no figure here, so the lease's number is the one that governs - pin it down.
Your Rights as a Boston Tenant
-
A child cannot end your tenancy
M.G.L. c. 186 § 16 provides that a lease term whose effect is to terminate the tenancy because the tenant has a child occupying the premises is against public policy and void.
-
Rooming-house occupancy becomes a tenancy
M.G.L. c. 186 § 17 makes three consecutive months of occupancy in a licensed rooming or lodging house a tenancy at will. Fraternity, sorority and educational dormitory units are excluded.
-
An executed copy within 30 days
940 CMR 3.17 requires the owner to give you an executed copy of any written rental agreement within 30 days of obtaining your signature.
-
The lease binds them too
Where our record finds no statutory procedure, the approval steps your rental agreement promises are what govern. A landlord who wrote a process cannot invent a different one later.
What To Do - Step by Step
Reread the occupancy paragraph
Find the exact wording on added occupants, guests, approval and fees. With no added-occupant provision found in our Massachusetts record, that paragraph is what a judge reads.
Get the executed copy in hand
940 CMR 3.17 requires an executed copy of a written rental agreement within 30 days of your signature. Ask for it in writing if you never received one.
Count the full-time undergraduates
Boston's Zoning Code Article 2 provides that a group of five or more enrolled full-time undergraduates is not deemed a family. Settle that before anyone gives notice elsewhere.
Ask in writing, with a date
Email the request with the person's name and move-in date. It creates the only timeline you will have, since our record supplies none.
Check whether a child is the real issue
If the objection traces to a child occupying the unit, M.G.L. c. 186 § 16 voids a lease term whose effect is to end the tenancy on that basis. Name the section.
Verify the current text before relying on it
Read M.G.L. c. 186 and the current Boston Zoning Code Article 2 definition as published, or ask a Massachusetts tenant-rights group, before acting on a denial.
