Subletting 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
- The section index of G.L. c. 186 runs from § 1A to § 31 and our record found no subletting or assignment provision listed in it.
- Nothing our record identifies puts a clock on your landlord's reply, so the answer deadline is whatever your lease promises.
- 940 CMR 3.17, the Attorney General's landlord-tenant regulation, covers conditions, notices, deposits, evictions and entry - and carries no subletting provision.
- Boston's short-term rental ordinance defines a short-term rental as occupancy of fewer than 28 consecutive calendar days for a fee, and an operator must be a natural person who owns the unit.
- Our record finds no Boston rule setting a response deadline or a reasonableness standard for an ordinary sublet request.
Understanding the Subletting Clause
A subletting clause decides whether you can hand your Boston apartment to somebody else for part of your term, and what happens if you skip asking. Our Massachusetts record answers the timing question with a flat no deadline: nothing it identifies requires your landlord to reply by any date or to justify a refusal.
That pushes the whole question into the paragraph you signed. Boston does have a real ordinance in this area, but it is aimed at short stays of fewer than 28 consecutive days rather than at a summer subletter, and read the current text of the sources named below before you rely on any of it.
What renters assume
Renters treat a summer sublet as their own arrangement: find someone dependable, hand over the keys, tell the office afterwards. Around the Fenway, in Allston triple-deckers and anywhere a September-to-September lease outlasts a job, that is the default plan.
What is actually true
Our Massachusetts record identifies no statutory right to sublet, so a clause requiring written consent is the operative rule. Moving someone in without that consent is a breach of the agreement you signed.
This chart is nearly empty, and that is the real finding. Only New York City's renters have a statutory answer - a landlord there must respond within 30 days. In Boston, as in every other city on this chart, the reply deadline is whatever the lease says it is, which makes this the clause where almost every renter's answer comes from the contract rather than the law.
Plain English Version
Subletting in Massachusetts works like lending out something you are still on the hook for - the written agreement you signed decides whether it is allowed, and our record shows no state clock forcing an answer. If your clause says ask first, you ask first, and nothing we found limits how long the reply can take.
Subletting 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.
Occupancy of Premises — Tenant shall not assign nor underlet any part or the whole of the premises, nor shall permit the premises to be occupied for a period longer than a temporary visit by anyone except the individuals specifically named in the first paragraph of this tenancy, their spouses, and any children born to them hereafter, without first obtaining on each occasion the assent in writing of Landlord.
Quoted from the published opinion in Slavin v. Rent Control Board of Brookline, 406 Mass. 458, 548 N.E.2d 1226 (1990). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“shall not assign nor underlet any part”
An assignment hands the tenancy over; an underletting leaves you the tenant with someone under you; this paragraph bars both. The Supreme Judicial Court read this clause and refused to add anything to it: a residential lease requiring written assent before an assignment, an underletting or an additional occupant carries no implied duty to act reasonably. Absent lease language, or a statute, saying consent will not be unreasonably withheld, the landlord may refuse arbitrarily.
“longer than a temporary visit by anyone”
The same ruling reaches this half: it covers an assignment, an underletting or an additional occupant, so a guest who stops being temporary meets the same written-assent gate as a subtenant. Our Massachusetts record finds no section fixing when a visit becomes an occupancy.
“their spouses”
A spouse and children born later are provided for; an unmarried partner, a parent or a roommate are not, and each needs written assent. Massachusetts leaves that list alone: 940 CMR 3.17, the Attorney General's landlord-tenant regulation under G.L. c. 93A, covers conditions, notices, rental agreement terms, deposits, evictions and entry, and our Massachusetts record finds no subletting provision in it.
“on each occasion”
Every time, separately: a yes for last summer's subletter is not a yes for this one. A blanket refusal to accept any replacement occupant did not excuse the tenant's breach, and the certificate of eviction was ordered to issue. The court handed the question to the Legislature, naming in a footnote four states that had already legislated.
The landlord did not have to be reasonable, and the tenant lost. The Supreme Judicial Court read this clause and refused to add anything to it: a residential lease requiring the landlord's written assent before an assignment, an underletting or an additional occupant carries no implied duty to act reasonably. Absent express lease language - or a statute - saying consent will not be unreasonably withheld, the landlord may refuse arbitrarily, so a blanket refusal to accept any replacement occupant did not excuse the tenant's breach. The annulment of the rent board's decision was affirmed and the certificate of eviction ordered to issue. The court knew it was declining a trend: it found no demonstrable trend involving residential leases, reasoned that in a rent-controlled town a landlord has little economic incentive to withhold consent, warned that the opposite rule would generate a plethora of litigation, and handed the question to the Legislature - noting in a footnote that four states had already legislated, New York's Real Property Law § 226-b among them. Two limits belong with the holding. The disposition was not a clean sweep: the court reversed the Appellate Division's award of double costs and attorneys' fees even as it affirmed the annulment. And the closing footnote says the court makes no suggestion about the rule it might adopt in other contexts - this is a rule about residential leases and nothing wider.
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 Subletting Clause
- The official section index of G.L. c. 186 runs from § 1A to § 31 and lists no subletting or assignment provision, so nothing in the state's landlord-tenant chapter grants a right to sublet or puts a clock on the landlord's answer.
- 940 CMR 3.17, the Attorney General's landlord-tenant regulation issued under G.L. c. 93A, covers unit conditions, notices, rental agreement terms, security deposits and last month's rent, evictions and entry, and carries no subletting provision.
- With no statutory standard, whether a Boston tenant may sublet, and whether a refusal has to be reasonable, is decided by the wording of the lease's own sublet clause.
- Boston Mun. Code 9-14.4A(B) makes a unit ineligible for the short-term rental registry where any local, state or federal law prohibits the leasing or subleasing of that unit.
M.G.L. c. 186 (no subletting or assignment section) - statutes change; verify the current text for your situation.
Our Massachusetts record checked the official section index of the state's landlord-tenant chapter, G.L. c. 186. That index runs from § 1A through § 31, and no subletting or assignment provision is listed anywhere in it.
Be precise about what that means. Our record says no subletting section was found in the index, not that the state's code has been read line by line - only the section titles were reviewed, so a rule sitting inside a section whose title does not disclose it is not ruled out. That is why thiswhy the sensible next step is to open the chapter yourself.
The other place a rule might have lived is 940 CMR 3.17, the Attorney General's landlord-tenant regulation issued under G.L. c. 93A. Our record reviewed it and found it covers unit conditions, notices, rental agreement terms, security deposits and last month's rent, evictions and entry - and carries no subletting provision.
The practical effect is the same either way. With no statutory standard our record can point to, whether you may sublet at all, and whether a refusal has to be reasonable, is decided by the wording of your own sublet clause. A written promise that consent will not be unreasonably withheld is worth more here than in a state with a statute, because it is the only such duty you are likely to have.
Massachusetts Tenant Protections
The strongest protection a Boston renter has on this clause is the one they negotiate. Because our Massachusetts record identifies no statutory sublet fee, no approval standard and no answer deadline, every charge and condition attached to a sublet has to come from the lease itself - which means it is negotiable before you sign rather than imposed afterwards.
A clause promising a written decision, a named reply window, or that consent will not be unreasonably withheld binds as a contract term even though our record shows no statute demanding one.
Boston Mun. Code 9-14.4A(B) also works in your favour in one narrow way: it makes a unit ineligible for the city's short-term rental registry where any local, state or federal law prohibits the leasing or subleasing of that unit, so a landlord cannot both bar your subletting and run the unit through the registry on that basis.Confirm the current text of the chapter and the ordinance before relying on these points.
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 does have a rule here, and it is the one thing a Boston renter most needs to get right - but it is about short-term rentals, not about handing your room to a roommate for the summer. Under Boston Mun. Code 9-14.2, a short-term rental is use of a residential unit for occupancy of fewer than 28 consecutive calendar days for a fee, and 9-14.3 provides that no residential unit shall be offered as a short-term rental except in compliance with that section.
The registry is where most renters' plans end. It is open only to an operator, defined as a natural person who is the owner of the unit, and 9-14.5(E)(1) makes the operator certify at registration that he or she is the owner. A home share or limited share unit must also be the operator's primary residence, which the ordinance defines as residing there nine months out of twelve. If you rent rather than own, that ownership requirement is the wall.
Draw the line clearly. A three-month handoff to a summer subletter is not a short-term rental under 9-14.2, because the stay is not fewer than 28 consecutive days - so the ordinance is not what decides it. Our record finds no Boston ordinance setting a response deadline or a reasonableness standard for an ordinary sublet request, which leaves your lease clause doing all the work on the everyday version of this question.
It should name the steps and a reply window. Our Massachusetts record sets no deadline, so the only clock you get is the one printed in your lease.
That single line is your best leverage. Our record identifies no statutory reasonableness duty, but a written promise binds as a contract term.
Push back before you sign rather than after. A flat no means you carry rent on an empty unit for the rest of the term.
Watch for an administrative charge with no number attached. Our record sets no sublet fee either way, so insist on a fixed dollar amount in writing.

Red Flags to Watch Out For
-
Consent at landlord's sole discretion
Our Massachusetts record identifies no statutory reasonableness standard for sublet consent, so this wording leaves you very little to argue with.
-
No reply deadline in the clause
Our record shows no state answer deadline, so a lease silent on timing can leave your request open while your replacement finds somewhere else.
-
Unapproved sublet equals instant default
A clause turning any unapproved sublet into immediate breach converts a summer handoff into a default. Get written consent before anyone moves in.
-
Lease silent on short stays
Silence does not make a stay of fewer than 28 consecutive days lawful in Boston. 9-14.3 still requires compliance, and the registry is owners only.
-
Verbal approval from the leasing office
A staff member saying it is fine will not survive turnover. Get approval in writing, naming your subtenant and the exact dates.
Your Rights as a Boston Tenant
-
Your lease can beat the silence
Where our record finds no rule, a clause granting broader sublet rights or a promised reply window controls. Read your own paragraph before assuming no.
-
Every fee has to be in the contract
Our Massachusetts record sets no statutory sublet fee or approval standard, so any charge must be written into the lease you signed - and negotiated before you sign it.
-
A sublet ban blocks the city registry
Boston Mun. Code 9-14.4A(B) makes a unit ineligible for the short-term rental registry where any law prohibits the leasing or subleasing of that unit.
-
Written consent ends the argument
Once your landlord approves in writing, the sublease cannot later be recast as a breach. Get it on paper with your subtenant named and the dates spelled out.
What To Do - Step by Step
Read your sublet clause first
Find whether consent is required, what approval costs, and whether assignment is banned too. With no state clock in our record, that paragraph is the rulebook.
Check the current statute text
Only the section index of G.L. c. 186 was reviewed. Open the chapter yourself before you rely on it.
Count the days before anything else
Fewer than 28 consecutive calendar days for a fee is a short-term rental under Boston Mun. Code 9-14.2, and the registry is open only to an owner. A three-month handoff is not.
Ask in writing, always
Email your property manager the person's name, the dates and the rent. A written request is the only version you can prove later.
Screen your replacement yourself
Bring someone who already clears the building's income and credit standards. With no reasonableness duty in our record, a weak candidate is an easy refusal.
Set your own follow-up date and get the yes on paper
Our record gives your landlord no deadline, unlike New York City's 30 days. Pick a date, follow up in the same thread, and never let anyone move in on a verbal okay.
