How to sublease your apartment in Massachusetts

Subleasing is how most off-campus housing actually works in Boston: a tenant heads home for the summer, leaves for a co-op, or studies abroad, and someone else moves in for the remainder of the lease. The mechanics aren’t hard — but Massachusetts has a few specific rules (and one big trap around security deposits) that make the difference between a clean handoff and a lawyer’s phone number.

Here’s the practical, step-by-step version, with the MA-specific bits called out.

What “subleasing” actually means

A sublease is a side agreement where you (the existing tenant) rent out your unit — or a room in it — to someone else for part of the time left on your lease. You stay on the original lease with the landlord and remain responsible to them; the sublessee pays you and is responsible to you. It’s different from a lease assignment, which fully transfers your tenancy to a new person and ends your obligations. Most student situations are subleases, not assignments.

Step 1: Read your lease before you list anything

Almost every modern Massachusetts lease has a clause that requires the landlord’s prior written consent before you sublease. Some leases ban subleasing outright. A few are silent. Look for any section titled “Assignment and Subletting,” “Transfer of Interest,” or similar. If your lease forbids subleasing or requires consent, proceeding without it can be grounds for the landlord to terminate your tenancy — meaning both you and your sublessee end up on the street.

If the lease is silent, MA contract law generally allows subleasing, but it’s still smart to give the landlord a heads-up so they’re not surprised by a new face on move-in day.

Step 2: Get written landlord approval

Verbal “sure, sounds fine” from a landlord is not enough — memories get short, properties get sold, and you may need to show consent later. Ask for written approval (email counts) that:

• Names you and the proposed sublessee.
• Identifies the unit and the sublease dates.
• Confirms the rent the sublessee will pay.
• States that the master lease remains in effect and you remain primarily responsible.

Every listing on Student Spots requires proof that you have written landlord approval before the listing goes live. The point isn’t bureaucracy — it’s that subleases without consent collapse, and we’d rather you not have your deposit eaten while you’re on the other side of the world.

Step 3: Set the dates, the rent, and the realistic terms

A sublease can’t go longer than your own lease (you can’t sublease time you don’t have). Within that window, the typical student sublease runs from a defined start date to a defined end date — 32 days minimum on Student Spots, often a summer or a single semester.

Pricing is your call as the sublessor, with one caveat: some municipalities have rules around what counts as profiteering in short-term rentals, and your lease may forbid sublease rent that exceeds what you pay. For longer student subleases (32 days to a year), this is rarely an issue, but if you’re tempted to charge well above your own rent, talk to someone first.

Step 4: Screen sublessees responsibly

You can — and should — vet the people you’re handing your keys to. Reasonable screening questions cover proof of student status, timeline of stay, income or co-signer for the rent, references, and a quick background check if you both want one.

What you cannot do is screen on protected characteristics. The federal Fair Housing Act and Massachusetts G.L. c. 151B prohibit decisions based on race, color, national origin, religion, sex, familial status, disability, sexual orientation, gender identity, ancestry, age, marital status, veteran status, source of income, and more. We cover the full list and our own commitments on the Fair Housing page. Stick to the unit and the contract, never the person’s identity.

Step 5: Put it in writing

Massachusetts doesn’t statutorily require sublease agreements to be written, but oral subleases are a recipe for disagreements you won’t win. A good written sublease covers, at minimum:

• The names of the sublessor (you) and sublessee.
• The unit address.
• Start and end dates of the sublease.
• Monthly rent and the schedule (and to whom — usually you, who then pays the landlord).
• What’s included (utilities, parking, furniture) and what isn’t.
• Pet policy, smoking policy, guest policy — matching your master lease.
• Conditions of the unit on move-in (a photo walkthrough helps).
• That the master lease still controls — the sublessee can’t do anything you can’t do.
• Cleanup expectations and the move-out date.

On Student Spots, when a sublessor and sublessee agree to terms, we generate a sublease agreement and route it through DocuSign so both parties sign with a full audit trail — no PDF email chains.

The wrinkle most students miss: security deposits

This is the part where a quick generic guide will lead you astray. Massachusetts has one of the strictest security-deposit statutes in the country — M.G.L. c. 186 §15B. A few things to know:

• A residential security deposit in MA must be held in a separate, interest-bearing account in a Massachusetts bank, in the landlord’s name as trustee. Interest accrues to the tenant.
• That obligation belongs to the landlord. As a sublessor, you are not the landlord — you are still a tenant. You should not be collecting and holding a security deposit from your sublessee as if you were one.
• In practice, that means a clean sublease almost always involves either (a) no separate sublessee security deposit at all, or (b) a deposit that the landlord collects and holds under §15B if everyone agrees and the landlord is willing.
• A first-and-last-month-rent arrangement is fine; that’s rent, not a deposit, and it isn’t governed by §15B.

Student Spots does not collect or hold any security deposit on the platform — by design. The first platform payment runs through Stripe; later rent flows directly between renter and host. Anyone telling you to wire a “security deposit” to a personal account in MA is either uninformed or running a scam.

Step 6: The handoff and the move-out

On move-in day, do a brief walkthrough with the sublessee and photograph the unit. Hand off keys, utility account info, the building’s quirks, and the landlord’s contact. On move-out, the sublessee returns the unit at least as clean as they found it. Anything that needs fixing is on you (the sublessor) to handle with the landlord at the end of the master lease — you don’t have a separate landlord-tenant relationship to settle.

What if it goes sideways?

Remember: you remain primarily responsible on the master lease. If your sublessee stops paying you, you still owe the landlord the full rent. If they damage the unit, the landlord can deduct from your deposit, and your recourse is against the sublessee directly under the sublease agreement. The same goes for late-night noise, illegal activity, or anything else the master lease forbids.

This is the single biggest reason to actually screen and to use a written agreement. Most student subleases go fine, but the ones that don’t go badly enough that the prep work pays for itself many times over.

Frequently asked

Can I sublease without telling my landlord?

If your lease requires consent, no — doing so risks termination. If your lease is silent, MA contract law generally allows it, but informing your landlord is still the practical move.

Is a 30-day sublease legal in MA?

Massachusetts doesn’t set a statewide minimum sublease length, but many municipalities regulate short-term rentals separately (Boston requires registration for stays under 28 days, for example). Student Spots requires a 32-day minimum on every listing to stay clearly outside short-term-rental rules.

Can I charge my sublessee more rent than I pay?

Possibly — check your lease first. Many leases prohibit charging the sublessee more than the master rent. If yours doesn’t, MA law doesn’t generally cap student-sublease pricing, but local rules around short-term rentals can apply at very short durations.

Who returns the security deposit?

The landlord, to whoever they collected it from — almost always the original tenant — at the end of the master lease. Sublessors shouldn’t be holding sublessee deposits themselves; under M.G.L. c. 186 §15B, that authority sits with the landlord.

What does Student Spots add?

We screen each listing for landlord approval, generate the sublease agreement, route it through DocuSign, and process the first platform payment via Stripe. See how it works for the full flow and pricing for the fees.
