Sublet vs Lease Assignment vs Lease Break in NYC — The Complete Breakdown

You need out of your New York apartment. The job moved. The roommate situation collapsed. The city just stopped working for you the way it did in September.

So you start Googling — and you run into three terms that sound the same but are not: sublet, lease assignment, and lease break.

They lead to different paperwork, different costs, and different rights under New York law. Pick the wrong one and you can lose a month of rent, your security deposit, or end up with a tenant screening report you'll be explaining for the next seven years.

Here's the plain breakdown — what each one is, what it costs in NYC in 2026, and the law that actually controls each path.

Sublet vs lease assignment vs lease break: the quick answer

A sublet means you stay on the lease and rent your apartment to a subtenant. A lease assignment means you transfer the entire rental agreement to a new tenant (the assignee) and walk away. A lease break means you terminate the lease early, with or without a buyout agreement.

Most NYC renters say "I need to break my lease" when what they actually need is a sublet.

What is a sublet in NYC?

A sublet is when the original tenant (the sublessor) rents the apartment to a third party (the sublessee or subtenant) while keeping their own name on the lease. You stay legally responsible to the landlord. The subtenant pays you. You pay the landlord. If the subtenant stops paying or damages the unit, the landlord still comes after you — not them.

In NYC, subletting is governed by Real Property Law § 226-b. In any building with four or more units, you have a statutory right to sublet, and your landlord cannot unreasonably withhold written consent — even if your lease says "no subleasing."

A sublet is the right tool when:

• You're leaving for an internship, a clinical rotation, a semester abroad, or a summer stretch.
• You want to come back to the unit.
• You hold a rent-stabilized apartment and want to preserve it long-term.
• You don't want the credit risk of a buyout or a housing court judgment.

The downside: you remain the prime tenant (sometimes called the master tenant). If your subtenant becomes a holdover or stops paying, you're the one in housing court.

What is a lease assignment in NYC?

A lease assignment is when you (the assignor) transfer your entire lease to a new tenant (the assignee), and your name comes off it. The assignee takes over rent, utilities, the security deposit, and all future liability. You walk away clean.

Assignments are also covered by RPL § 226-b, but the landlord has more discretion to refuse. Unlike subletting, a landlord can deny an assignment for almost any reason. If they do, your only remedy is to be released from the lease — and that's actually the point. You offer them an assignment, and either they accept the new tenant or they let you out.

A lease assignment is the right tool when:

• You're leaving New York permanently.
• You have a qualified replacement tenant ready to take the unit long-term.
• You want to be done — no managing a subletter, no liability tail, no monthly check-ins.

The downside: most NYC landlords prefer a sublet (it keeps you on the hook) or a buyout (cash now). Assignments take negotiation.

What is a lease break in NYC?

A lease break is when you terminate the rental agreement before the end date, either with legal cause or by paying a negotiated buyout. No replacement tenant required. The lease just ends.

Lease breaks fall into two categories:

1. Legal cause — no penalty. Active military duty under SCRA, uninhabitable conditions under the warranty of habitability (RPL § 235-b), domestic violence (RPL § 227-c), senior or disability relocation (RPL § 227-a), or documented landlord harassment.
2. Negotiated buyout. You pay 1–3 months rent and the landlord signs a release. This is the standard exit when there's no legal cause and no replacement tenant.

A lease break is the right tool when:

• You have a legal cause that protects you under New York law.
• You can't find a subtenant or assignee in time.
• You'd rather pay 1–2 months than spend three months managing a sublet.

The downside: cash up front. And if you walk without a written buyout agreement, the landlord can sue for the remaining rent — limited only by their duty of mitigation of damages under RPL § 227-e.

Sublet vs assignment vs lease break: which one should you pick?

The decision tree is short.

• Coming back to the unit? → Sublet.
• Leaving permanently with a replacement tenant ready? → Assignment.
• Leaving permanently with no replacement? → Buyout (lease break).
• Have legal cause? → Lease break with no penalty.
• Rent-stabilized? → Sublet only. Never assign a stabilized lease without a tenant attorney.

If you're stuck between a sublet and an assignment, default to a sublet. You keep optionality, you keep the apartment, and you keep your rent-stabilized status if you have it.

How does subletting work in NYC, step by step?

Under RPL § 226-b, the process is specific. Skip a step and the landlord can deny consent or claim a breach.

1. Send a written sublet request by certified mail. Include the proposed sublease term, the subtenant's name and home/business address, your reason for subletting, your address during the sublet, the subtenant's written consent, and a copy of the proposed sublease.
2. The landlord has 10 days to ask you for more information.
3. Within 30 days of your original request (or the date they received your follow-up info, whichever is later), the landlord must either consent in writing or send a written denial with reasons.
4. Silence counts as consent. If 30 days pass with no response, you can legally sublet.
5. If denied unreasonably, you can sublet anyway and raise the landlord's refusal as a defense in any future action.

Most NYC tenants skip the certified mail step. Don't. The paper trail is the whole game if it ends up in housing court.

How does a lease assignment work in NYC?

The procedure mirrors a sublet request, but the outcome is different.

1. Send a written assignment request to the landlord with the assignee's name, financials, and written consent.
2. The landlord has 30 days to respond.
3. If the landlord refuses, you choose: stay on the lease, or be released from the lease entirely within 30 days of giving them notice that you accept the refusal.
4. If the landlord consents, sign an assignment agreement that explicitly releases you from future liability. Without that release in writing, you can still be on the hook.

The release is the only part that matters. Don't sign an assignment without it.

How much does each NYC exit actually cost?

The 2026 numbers, depending on the path you take.

A clean buyout almost always beats walking away. A clean sublet almost always beats a buyout. But that math depends entirely on how fast you can place a qualified replacement tenant — which is where most renters get stuck.

What does New York law actually require?

Three statutes do most of the heavy lifting in any sublet, assignment, or lease break dispute.

• RPL § 226-b — your right to sublet and assign. Applies to buildings with four or more units. Lease language cannot override it.
• RPL § 227-e — your landlord's duty of mitigation of damages if you leave early. They must make reasonable efforts to re-rent the unit. This caps your financial exposure.
• RPL § 235-b — the warranty of habitability. Uninhabitable conditions can be grounds for constructive eviction, meaning you break the lease with no penalty.

Together, these three statutes mean a NYC tenant is almost never as trapped as the lease language suggests.

Can your landlord say no to a sublet in NYC?

Your landlord can deny a sublet request, but only with a reasonable basis — and only in writing within 30 days. Reasonable reasons include a subtenant with poor credit, an unverifiable income source, or a proposed term that violates the lease (such as turning the unit into an Airbnb).

Unreasonable denials don't hold up. If the landlord ignores your request, denies it without giving a reason, or rejects every subtenant you propose with no justification, you can sublet anyway. Their silence or unreasonable refusal becomes your shield.

The exception: buildings with fewer than four units. In a brownstone with three apartments, RPL § 226-b doesn't apply and the lease controls.

Can your landlord say no to a lease assignment?

Yes. A landlord can refuse a lease assignment for almost any reason in NYC. Unlike subletting, the standard isn't "reasonableness" — landlords have wide discretion to reject an assignee.

The protection: if they refuse, they must release you from the lease within 30 days of your notice. That's the trade. Either they accept the new tenant or they let you out. The one outcome the law does not allow is keeping you locked in and refusing the assignment.

How does subletting work for a rent-stabilized apartment?

Rent-stabilized tenants in NYC have the same § 226-b sublet rights, plus a few extra rules:

• The unit must be your primary residence, and you must intend to return.
• The sublet rent can be no more than 10% above your stabilized rent if the apartment is furnished, or your stabilized rent exactly if unfurnished.
• A sublet cannot last more than two years out of any four-year period.
• You cannot permanently assign a rent-stabilized lease without the landlord's specific written consent. Doing so risks losing the stabilized status entirely.

If you're stabilized and thinking about leaving for good, talk to a tenant attorney before signing anything. A stabilized lease is worth more than most people realize.

What is the notice period to break a lease in NYC?

For a fixed-term lease, the notice period is whatever the lease specifies — usually 30 to 60 days, sent in writing. For month-to-month tenants, New York's statutory notice depends on how long you've lived there:

• Less than 1 year: 30 days written notice
• 1 to 2 years: 60 days written notice
• More than 2 years: 90 days written notice

Notice must be in writing, dated, signed, and sent by certified mail with return receipt. Verbal notice doesn't count.

What's the cleanest way to find a subtenant in NYC?

The cleanest path is a furnished, short-term sublet platform that matches your apartment to vetted renters who actually need 1–6 months — interns, summer associates, grad students, residents, and new grads. Craigslist and Facebook groups still work, but the tenant screening burden is on you and the timing is brutal.

snag was built for this exact moment. A sublet platform for furnished, short-term NYC rentals from one month up to a year. Post your apartment, get matched with renters in the opportunity zone — internships, rotations, semesters — and stop bleeding rent while you wait.

The faster you place a subletter, the less leverage your landlord has, the less you owe under any buyout agreement, and the cleaner your exit looks if a dispute ever ends up in housing court.

FAQ: Sublet vs assignment vs lease break in NYC

What's the difference between subletting and assigning a lease in NYC?

Subletting keeps you on the lease — you rent the unit to a subtenant but stay legally responsible to the landlord. A lease assignment transfers the entire rental agreement to a new tenant (the assignee), releasing you from future rent and liability. Subletting is for temporary moves. Assignment is for permanent ones.

Is subletting legal in NYC?

Yes. Real Property Law § 226-b guarantees the right to sublet in any building with four or more units, and the landlord cannot unreasonably withhold consent — even if your lease prohibits subleasing. You must follow the statutory notice procedure, including a written request sent by certified mail.

Do I need my landlord's written consent to sublet in NYC?

Yes, on paper. You must send a written sublet request, and the landlord has 30 days to respond. Silence counts as consent. If they refuse, the refusal must be reasonable and in writing. Skipping the notice step is the most common mistake NYC renters make.

Can I assign my lease if my landlord says no?

If the landlord refuses your assignment request, they must release you from the lease within 30 days of your notice. You cannot be locked in and denied the assignment. That's the trade-off built into RPL § 226-b — landlords get discretion, tenants get an exit.

What's the cheapest way to break a lease in New York?

A clean sublet is the cheapest exit because you don't pay a buyout and you keep collecting rent from your subtenant. The next cheapest is a lease assignment if you have a qualified replacement tenant. A negotiated buyout (1–3 months rent) is the most common cash exit when no replacement exists.

Does a lease break show up on my credit report?

No. Breaking a lease isn't reported to credit bureaus by itself. What shows up is unpaid rent sent to collections or a housing court judgment. A clean buyout, sublet, or assignment leaves no mark on your credit. Walking away without a plan is the move that wrecks it.

Can my landlord charge me rent after I leave if I break the lease?

Only until the unit is re-rented. New York's RPL § 227-e requires landlords to make reasonable efforts to re-rent — known as the duty of mitigation. Once a new tenant signs, your obligation ends. If the landlord refuses to advertise or rejects qualified applicants, you can raise that as a defense.

What is a buyout agreement in NYC?

A buyout agreement is a signed written release in which the landlord agrees to let you out of your lease in exchange for a payment, usually 1 to 3 months rent. It ends your obligation in full. Always get it in writing — a verbal buyout is not enforceable.

The bottom line

Three exits, three different sets of rules.

• A sublet keeps you in control, on the lease, and collecting rent from your subtenant.
• A lease assignment hands the keys to someone else and ends your liability.
• A lease break ends the agreement outright — clean if you have legal cause or a buyout, messy if you walk.

For most NYC renters, subletting is the answer. It's cheaper, it preserves your tenancy, and § 226-b gives you the leverage to force landlord consent if they stall. The piece that holds people up is finding the right subletter fast enough to matter.

That's the gap snag closes. Post your apartment, get matched with renters who need a 1, 3, or 6 month stay, and hand off the keys before the next rent check is due.

Your lease shouldn't decide your year.
