The keys don't work. Or they do, and the last tenant's furniture is still in the living room. One Boston renter described arriving to find "the unit was still full of trash, dirt, food," with a truck outside and nowhere to put anything.
September 1 makes this a Boston problem at Boston scale. Much of the city turns over on the same day, which means the gap between one tenant leaving and the next arriving is measured in hours, and when it goes wrong there is no slack anywhere in the system.
Here is what the law actually requires, what evidence to create in the first two weeks, and which remedies have conditions attached before you can use them.
The landlord's duty comes before your tenancy
The landlord's obligation starts before you move in, not only once you complain.
MassLegalHelp puts it plainly: "The law requires landlords to put apartments in good condition before renting them."
What "good condition" means is set out in the State Sanitary Code at 105 CMR 410, which establishes the minimum standards of fitness for human habitation. Alongside it sits the implied warranty of habitability, built from Massachusetts case law and reinforced by the code.
That warranty is non-waivable. Massachusetts does not permit a residential tenant to sign it away. So a lease clause saying you accept the apartment "as is," or that you have inspected it and found it satisfactory, does not remove the landlord's obligation. Plenty of leases contain language like that.
Your best tool is a form most renters ignore
If your landlord took a security deposit, they owe you a written, signed Statement of Condition. It is due when you pay the deposit or within 10 days of the start of your occupancy, whichever is later.
It has to list any damage existing in the premises, including certified sanitary or building code violations, and it carries a required notice in 12-point bold type explaining your right to respond.
You then have 15 days to return it with corrections, counted from when you receive it or from when you move in, whichever is later.
Most renters treat this as deposit paperwork and file it, but on a bad move-in day it is a statutory record of the unit's condition, in writing, that your landlord has signed. If the apartment was filthy, damaged or unusable on day one, that is the document where it goes.
Two practical notes. First, if the statement arrives listing the apartment as flawless, that is exactly when to use your 15 days rather than letting it stand. Second, a landlord who mishandles the deposit process faces real consequences under § 15B, which is covered in our guide to itemized receipts and deposit rights.
Whether or not a deposit was taken, photograph everything before you move a single box in. Date-stamped photographs of an empty unit are the cheapest evidence you will ever create, and you cannot go back for them.
What you can actually do, and what each one requires
Your options run from free and immediate, like documenting the condition and calling the board of health, to heavily conditioned, like repair and deduct. Several remedies have preconditions that have to be satisfied first, and acting without them can leave you in a worse position than you started.
| What you can do | What it requires first |
|---|---|
| Document the condition | Nothing. Do it today, before anything moves in |
| Use the Statement of Condition | That a deposit was taken. Then the 10-day and 15-day clocks apply |
| Report to the board of health | Nothing. They inspect and can certify violations |
| Repair and deduct (M.G.L. c. 111, § 127L) | Certification of the violations, written notice to the owner, and then their failure to act. See below |
| Withhold rent, or end the tenancy | Conditions apply that this guide does not cover. Get advice before doing either |
Repair and deduct is the one people reach for and the one most often misunderstood. It is not a button you press. Under M.G.L. c. 111, § 127L it applies where violations "may endanger or materially impair the health, safety or well-being" of the occupant, and it requires that the violations be certified by a board of health, a code enforcement agency, the commissioner of housing inspection (in Boston, Worcester and Cambridge) or a court.
Only then does the clock start. The owner must receive written notice and then fail to begin the necessary repairs within five days, or fail to substantially complete them within fourteen. And there is a ceiling: the statute says a tenant "may not deduct pursuant to this section an amount greater than four months' rent in any twelve-month period, or period of occupancy, whichever is shorter."
The first move in almost every case is the same and it is free: call the board of health or inspectional services and ask for an inspection. That creates the official record everything else depends on. Our guide to who to call about a landlord problem in Boston sets out the order to work through.
If the problem is pests specifically, that has its own rules about who pays and what the landlord must do, and we have covered it separately in what to check for pests and who pays. If the unit is bad enough that living there is genuinely in question, what to do when an apartment is unlivable goes further than this guide does.
If the landlord pulls out before you sign
Until a lease is signed, you do not have an apartment, regardless of what you have been told, how confident the agent sounded, or how strong your application was. Verbal assurance from a leasing agent is not a tenancy, and it is not a contract.
That is what happened to a Boston renter on September 1 this year: the realtor confirmed everything, a cosigner was in place, and on the morning of the move the landlord simply declined to take them on, with no explanation and no apartment to show for it.
That is a general problem worth understanding before it happens to you, and we have written it up properly in what a leasing agent tells you is not the lease. If you have been turned down rather than left hanging, what to do when a rental application is denied is the more useful place to start.
The practical protection is unglamorous: keep looking until the lease is signed, and do not release your current place or book movers on the strength of a phone call.
This is not usually anyone behaving outrageously. A landlord can change their mind about an applicant right up until they are contractually committed, and an agent relaying enthusiasm is not the same as an owner signing. Your paperwork, income, and cosigner do not protect you until the lease is signed.
If it does happen to you, two things are worth doing the same day. Ask for whatever was paid to be returned, in writing, and keep every message from the agent. If money changed hands on the strength of an assurance, that record is what any later conversation will turn on.
Moving in a day early
Moving in before your official lease start date creates the opposite problem, and it shows up just as often around September 1, usually because the truck is only available on the 31st.
Two things are worth separating. The outgoing tenant's permission is not the landlord's permission. If their lease runs to the end of the month, the unit is theirs until it ends, and them being fine with it does not make it authorized. The realistic risk is less dramatic than people fear and more annoying than they expect: cleaners or maintenance arriving to an apartment they believed was empty, a dispute about who is responsible for anything damaged in the overlap, and no clear answer about whose insurance covers what.
If you need the day, ask the management company in writing and get the answer in writing. Our guide to coordinating lease dates in Boston covers planning around the gap properly.
Where this stops being general advice
Whether a specific unit's condition actually violates the code. That is what an inspection determines.
Whether you can withhold rent, repair and deduct, or end the tenancy. These have conditions, and getting them wrong is expensive. This guide deliberately does not tell you that you can.
What a landlord owes you for a failed or delayed move-in. This depends on what was signed, what was paid, and what happened, so it needs individual legal advice.
Whether a verbal approval created any obligation at all.
For all of these: your local board of health or inspectional services handles code enforcement and inspections, MassLegalHelp is a good free starting point, Greater Boston Legal Services advises income-eligible tenants, and a tenant-rights attorney can advise on your specific tenancy.
Frequently asked questions
Does a landlord have to clean an apartment before I move in? Massachusetts requires landlords to put apartments in good condition before renting them, and the State Sanitary Code at 105 CMR 410 sets the minimum standards. A unit full of the previous tenant's belongings and debris is not that.
Can my lease say I accept the apartment "as is"? It can say it. The implied warranty of habitability is non-waivable for residential tenants in Massachusetts, so a clause like that does not remove the landlord's underlying obligation.
What is a Statement of Condition? A written, signed statement of the apartment's condition that a landlord who takes a security deposit must give you, on payment of the deposit or within 10 days of occupancy, whichever is later. It must list any existing damage in the premises, and you have 15 days to return it with corrections.
What if the Statement of Condition says the apartment is perfect and it isn't? That is what the 15 days are for. Return it with your corrections rather than letting an inaccurate record stand.
Can I just fix the problem and take it off the rent? Not immediately. Repair and deduct under M.G.L. c. 111, § 127L requires the violations to be certified by a board of health, code enforcement agency, commissioner of housing inspection or court, written notice to the owner, and then their failure to begin within five days or substantially complete within fourteen. It is capped at four months' rent in any twelve-month period, or your period of occupancy if that is shorter.
Can I refuse to move in and get my money back? That depends on what was signed and what happened, and it is a question for legal advice rather than a guide. Document everything first, because that is useful whichever way you go.
What should I do in the first hour? Photograph and video everything before anything comes off the truck, in daylight if you can. Then contact the landlord or management in writing, so the complaint is dated.
The landlord canceled on the day. Do I have any claim? Possibly, and it depends heavily on whether a lease was signed and what was paid. Until a lease is signed you do not have a tenancy, which is why the answer turns on the paperwork rather than the conversation.
Who do I call first? Your local board of health or inspectional services. An inspection creates the official record that most other remedies depend on.
