How Do You Sublease an Apartment? (w/Examples) + FAQs

You sublease an apartment by rereading your lease, getting your landlord's written consent, screening a subtenant, and signing a separate sublease agreement. Your name stays on the original lease the whole time, and that is the part that trips up most first-time subletters.

Skipping a step carries real risk, from a denied request to an eviction filed months later. New York's Rent Guidelines Board still requires a landlord to act on a written subletting request within 30 days, or consent becomes automatic. Most other states leave that timeline undefined, which is exactly why putting every step in writing matters everywhere else.

What Counts as Subleasing

This article reflects general landlord-tenant practice and the state examples below as of August 2026. Rules change and vary by city and state. Confirm your own lease and local law before you act, and talk to a tenant attorney or your state's housing agency if your case gets hard to sort out. Nothing here replaces advice from a professional who has read your actual lease.

A sublease happens when you, the primary tenant, rent your apartment to someone else for a while. That person is a subtenant. Your name stays on the original lease while they live there, because you plan to come back. The subtenant never signs your lease, so they have no direct legal tie to your landlord at all.

That missing tie is the detail that catches people off guard. Your landlord can only look to you, not your subtenant, if rent goes unpaid or the unit gets damaged. Nolo's sublet guide puts it simply: subletting builds a new legal bond between you and your subtenant, on top of a landlord bond that never changes. In effect, you become a small landlord yourself for the length of the sublease.

Subletting is also not the same as handing off your unit for good, and it is not the same as adding a roommate. Maryland's sublease guide, from a university housing office, draws a clean line here. A sublease is for tenants who plan to return, while a lease assignment (sometimes called a relet) is for tenants who are leaving for good. Mixing up the two leads people to sign the wrong paperwork for what they intend to do.

Before you go further, try a five-minute self-check. Pull out your lease and search the text for the word "sublet" or "assign." Most leases spell out whether you need permission, how much notice to give, and what your landlord can ask about a subtenant. That one read often answers what people otherwise pay an attorney to research.

Which Situation Applies to You?

The right path depends on whether you plan to return, how long you will be gone, and what your building allows. The table below gives a fast read. The sections after it explain the reasoning behind each choice.

Your Situation	What To Do
Leaving for a set period and planning to return	Sign a sublease agreement and keep your name on the original lease
Leaving for good with no plans to come back	Ask about a lease assignment, an assumption, or a mutual lease cancellation
Only want to add a full-time roommate	Skip subletting and ask your landlord to add the roommate directly
Living in a rent-stabilized apartment in a city like New York	Follow the certified-mail notice process and its firm deadlines

You're Leaving Temporarily and Plan to Return

A study-abroad term, a travel-nursing job, or a few winter months somewhere warmer are the classic sublease cases. This is also the group the rest of this article is written for. You want to keep your unit, your rent, and your lease terms exactly as they are. A sublease lets you pause them without breaking the lease early or paying a fee that can run one to two months' rent.

The tradeoff is that you stay on the hook the whole time you are gone. If your subtenant stops paying or damages the kitchen, your landlord comes after you first, not them. You would then need to separately chase your subtenant to recover what you had to cover. That risk shrinks with careful screening and a solid written agreement, both covered later in this article.

You're Leaving for Good

If you are moving away with no plan to return, a straight sublease is the wrong tool, even though people reach for it out of habit. A lease assignment or a lease assumption hands your remaining lease term to the new tenant. Depending on your landlord's paperwork, a signed assignment can fully clear you of future liability. That clean break also frees up your own rental history for the next place you rent.

Ask your landlord directly whether they offer an assignment, an assumption, or simply canceling the lease so a new tenant can sign a fresh one. Whichever option removes your name from future rent bills is usually the better choice, not a sublease that keeps you quietly attached. Devon's story, later in this article, shows exactly why that signed release matters.

You Only Want to Add a Roommate

Bringing in a new full-time roommate is not subletting at all, and treating it like a sublease adds paperwork you do not need. In most cases, the cleanest move is asking your landlord to add the new person straight to the lease. That gives your landlord a direct legal tie to your new roommate and takes you out of sole duty for their share of the rent. Renters insurance and utility accounts usually need updating too, so add a quick call to each provider to your moving checklist.

If your landlord refuses to add a new name and insists on a sublease deal instead, treat your new roommate exactly like any other subtenant. Run the same credit check and reference calls you would run on a stranger. A friend who cannot pay rent is still a friend who cannot pay rent, and your lease does not care about the friendship.

Step-by-Step: How to Sublease Your Apartment

Once you know a sublease is the right tool, the process follows a set order. Skipping steps out of sequence is where most avoidable problems start. Treat this as a checklist, not a rough outline you can rearrange.

Start by rereading your lease's subletting clause. It tells you whether you need written consent, how much notice to give, and what information about the subtenant your landlord can request. Some leases require 30 days' notice; others say nothing at all, and subletting is often allowed by default then. Write down the exact notice period first, since missing it can void an otherwise fair request.

Next, send your landlord a written request, even if your lease does not strictly require one. A short letter or email naming your proposed subtenant, the sublease dates, and your own temporary address protects you if your landlord later claims you never asked. Rocket Lawyer's subleasing guide recommends attaching the subtenant's credit history and references to that same request. A landlord who can already see the subtenant looks reliable has less reason to stall.

While you wait for a reply, screen your subtenant with the same steps your own landlord once used on you. Run a credit check, verify income, and call at least one past landlord. A subtenant who fails those checks is far more likely to become the unpaid-rent problem you are trying to avoid. Treat a subtenant who resists this process, or who wants to move in sight-unseen, as a warning sign rather than a shortcut.

Once your landlord approves and your subtenant passes screening, sign a written sublease agreement that covers rent, dates, and the deposit. Collect that deposit and the first month's rent before anyone gets a key. Walk through the unit together first and photograph its condition room by room, so neither of you has to guess later what changed. Only after the money clears and the walkthrough is done should you hand over keys and tell your landlord the subtenant has moved in.

What Belongs in a Sublease Agreement

A sublease agreement is a separate contract between you and your subtenant, distinct from your original lease. Start with the basics: the exact start and end dates, the monthly rent, and the day it is due each month. The end date must fall on or before your own lease's end date, and leaving that detail vague is a common source of disputes. Many agreements also ask the subtenant to carry their own renters insurance for the length of the sublease.

The security deposit deserves its own line, including the exact dollar amount and the terms for getting it back. Several states cap what you can collect from a subtenant. U-M's subletting tips note that a subtenant's deposit generally cannot exceed one and a half times their monthly rent, a cap also set by Michigan's own security deposit law as of this writing. Confirm your own state's cap before you set a number, since charging over the legal limit can force a refund later.

Name your subtenant fully and record a permanent address for them beyond the unit itself. Attach a copy of your original lease so they know the rules they are agreeing to follow, from noise limits to any pet policy. Spell out what happens if rent runs late, who handles small repairs during the sublease, and how either side can end the deal early if something goes wrong. Add a line about who covers utilities during the sublease term, since that detail is a frequent source of small disputes later.

A signature line for both of you, dated the same day as your walkthrough, closes the agreement. It gives you something concrete to point to if a fight ever lands in housing court. Keep a signed copy for yourself and hand your subtenant their own copy on the spot, not sometime later once you both remember to send it.

Worked Example: Setting a Fair Sublease Rent and Deposit

Numbers make this concrete. Jordan pays $1,800 a month for a one-bedroom apartment. He is subletting for the summer, three months, while working a temporary job in another city. His lease says nothing about subletting, so he still emails his landlord in writing and gets a reply confirming approval before he lists the unit.

Jordan sets his subtenant Casey's rent at the same $1,800 a month he already pays, matching what similar units rent for nearby. Renters swapping notes in one popular thread called apartments money sinks, only worth what a comparable studio nearby was charging, roughly $1,800 a month in that market. That comparison gives Jordan a useful gut check against setting his own number too high or too low.

His state caps a subtenant's security deposit at one and a half times the monthly rent. Jordan's math looks like this: $1,800 multiplied by 1.5 equals a $2,700 maximum deposit. Add the first month's rent and Casey owes $1,800 plus $2,700, or $4,500 total, due before Jordan hands over a key. Jordan writes both figures into the sublease agreement so neither of them has to redo the math later.

Casey ends up moving in five days late, on June 6 instead of June 1, so Jordan prorates that first month instead of charging the full amount. He divides the $1,800 monthly rent by 30 days in June, giving a daily rate of $60. He multiplies that by the 25 remaining days in the month: $60 times 25 equals $1,500 owed for June instead of the full $1,800. That one adjustment, worked out on paper before move-in, prevents an argument about a discount neither of them wrote down anywhere else, and it gives both Jordan and Casey a clean number to check against their bank statements at the end of the month.

Where Sublease Rules Differ by State

There is no single federal law that governs subletting an apartment. Residential leases fall under state and local landlord-tenant law, not federal statute. The specific notice periods, consent rules, and deposit limits described in this article can shift the moment you cross a state or city line, so treat every figure here as a starting point, not a final answer. A handful of states set a firm deadline for a landlord to respond to a sublet request, while most states leave that timeline unwritten.

Does My State Differ?

Some states go further than simply requiring your landlord's permission. Nolo's sublet guide lists California and Florida among the states that bar landlords from refusing consent without a fair reason. Rocket Lawyer's subleasing guide notes that San Francisco allows a one-for-one roommate swap without the full sublease process, as long as the new roommate meets the landlord's normal screening standards. A landlord in either state can still refuse a subtenant with a documented history of unpaid rent or eviction.

New York City adds another layer. State law is reported to let tenants in buildings with four or more units sublet even when their lease flatly forbids it. Rent-stabilized tenants there also get a formal, deadline-driven process: a written request sent by certified mail at least 30 days before the sublease starts, a 10-day window for the landlord to ask follow-up questions, and automatic consent if the landlord never replies within 30 days total. Those same tenants cannot demand "key money," and a prime tenant caught overcharging a subtenant on purpose can be forced to refund up to three times the overcharge.

None of that guarantees your own city follows the examples above exactly. Check your state's landlord-tenant statute, or ask a local tenant rights group, before assuming a rule from this article applies where you live. Deposit caps, notice periods, and whether silence counts as consent are the three details most likely to differ from state to state.

Three Sublease Attempts, Three Different Outcomes

Maria Does a Semester-Abroad Sublease by the Book

Maria is a graduate student with a $1,600-a-month lease who is spending a semester studying overseas. She wants to keep her apartment rather than break the lease early. She reread her lease, found a clause requiring 30 days' written notice, and sent that request by email right on schedule with her proposed subtenant's name and references attached. Her landlord approved within a week, in part because Maria had already run a credit check on her subtenant.

What Maria Did	Why It Worked
Gave written notice with the exact lead time her lease required	Removed any excuse for her landlord to claim she skipped the process
Pre-screened her subtenant before asking for approval	Made approval faster because the risk was already addressed
Signed a sublease agreement matching her own lease's end date	Avoided a gap where the subtenant would have no legal right to stay

Devon Learns the Difference Between Subletting and Walking Away

Devon shared a two-bedroom apartment and took a job across the country, with no plan to come back at all. He first planned to sublet as a friend once had, until he realized subletting would leave his name on the lease with no end date. Instead, Devon asked his landlord for a lease assignment, and after the new tenant passed screening, his landlord signed a release that formally removed Devon from the lease.

That release is the detail people miss most often. Without a signed release, even an "assignment" can leave the old tenant on the hook if the new one stops paying. Forum accounts of illegal sublets keep landing on the same outcome: an eviction, a civil suit over the missing rent, and sometimes a warrant if the subletter skips the court date entirely. Devon's insistence on a signed release, not a verbal handoff, is what protected him.

Priya Skips the Landlord and Pays the Price

Priya needed to leave for four months and, pressed for time, found a subtenant through a campus posting board without telling her landlord. Her landlord found out two months in, when a maintenance visit turned up someone who was not on the lease. He filed to evict Priya for violating her lease's no-subletting clause, and Priya had no written record to defend herself with.

What Priya Skipped	What It Cost Her
Written notice to her landlord before advertising the unit	Gave her landlord clear grounds to file for eviction
Any subtenant screening or written sublease agreement	Left her with no leverage once the subtenant refused to leave
Reading her own lease's subletting clause first	Meant she never learned about the 30-day notice rule until it was too late

Because the violation was legally "curable," a judge gave Priya's subtenant a short window to move out rather than losing the apartment outright. The process still cost her weeks and a housing court appearance she could have skipped entirely. Similar threads describe the same warning: nobody will rent her a room again, because once an eviction lands, the mark follows a tenant for years. Priya's case is a reminder that the paperwork is the cheap part.

Mistakes to Avoid When Subleasing

• Not getting the landlord's consent in writing. A verbal "sure, go ahead" gives you nothing to point to if your landlord later denies ever agreeing, and courts side with whichever party has the paper trail.
• Skipping a written sublease agreement with your subtenant. Without one, a dispute over the move-out date or the deposit becomes your word against theirs.
• Not screening your subtenant. Accepting the first applicant without a credit check or references sets you up to cover their unpaid rent or repair bill later.
• Letting the subtenant move in before the deposit and first month clear. Chasing money after someone already has a key is far harder than collecting it up front.
• Charging more than your own rent in a rent-controlled market. A subtenant who files an overcharge complaint in a city like New York can force you to refund up to three times what you collected above the legal limit.
• Skipping a move-in walkthrough and photos. Without a documented starting condition, you cannot prove which damage is new when the sublease ends.
• Assuming your landlord's silence means approval. Outside a deemed-consent rule like New York's for rent-stabilized units, no response usually means no permission at all.
• Listing the sublease before checking your lease. Some leases specify exactly how and when to ask, and skipping that step can undercut an otherwise reasonable request.
• Letting the sublease term run past your own lease's end date. A subtenant still living there after your lease expires has no legal right to stay, and that becomes your problem to untangle.

Do's and Don'ts of Subleasing

Do

• Do read your lease's subletting clause before you do anything else. It tells you the notice period and what your landlord can ask about a future subtenant.
• Do put your sublet request in writing, even if your lease does not require it. A dated letter or email protects you if your landlord later claims you never asked.
• Do screen your subtenant with the same steps your own landlord used on you. A credit check and a past-landlord reference cut your risk of a subtenant who stops paying.
• Do collect the security deposit and first month's rent before handing over keys. Money collected after move-in is far harder to recover than money collected up front.
• Do walk through the unit with your subtenant and log its condition. Dated photos from before move-in settle disputes about damage months later.
• Do keep a copy of every signed document. Your original lease, the sublease agreement, and any written landlord approval all matter if a dispute lands in housing court.

Don't

• Don't assume an unwritten "no subletting" habit means you are safe. If your lease is silent, ask anyway to protect the relationship and your security deposit.
• Don't let a subtenant move in without a signed agreement. An informal handshake deal leaves neither of you anything enforceable if the arrangement falls apart later.
• Don't overcharge a subtenant in a rent-controlled unit. The refund owed for a willful violation can wipe out months of the extra rent you tried to collect.
• Don't ignore your own lease's end date when setting the sublease term. A sublease that outlives your original lease has no legal ground to stand on.
• Don't skip a background or credit check to save time. A bad subtenant costs far more in unpaid rent and repairs than a screening fee ever would.
• Don't hand over keys before the funds clear. A payment that falls through is much harder to chase once someone is already living in the unit.

Pros and Cons of Subleasing

Pros

• Keeps your lease intact. You avoid breaking a lease early and the fees or credit hit that usually come with ending it early.
• Covers rent while you're away. A subtenant's payment keeps your obligation to the landlord covered during a semester abroad, a work assignment, or an extended trip.
• Preserves your spot. You keep the legal right to return to the same apartment, which matters when local rents keep climbing.
• Costs less than breaking a lease. A sublease typically runs far cheaper than a lease-break fee, which can equal one to two months' rent.
• Builds a paper trail your landlord respects. A documented process, request, agreement, and deposit, tends to smooth over any dispute that comes up later.

Cons

• You stay liable for someone else's mistakes. Unpaid rent or damage from your subtenant becomes your bill, not theirs, until the sublease ends.
• It takes real paperwork. A sublease agreement, subtenant screening, and often a formal landlord request add real time before you can leave.
• Your landlord can say no. Outside a handful of tenant-friendly states, a landlord can refuse consent for a reason you may never learn.
• Screening isn't foolproof. Even a subtenant with clean references and good credit can stop paying rent or damage the unit after moving in.
• Local rules can shrink what you can charge. Rent-controlled cities cap the rent and deposit you can collect, sometimes well below the market rate.

What to Do Next

1. Reread your lease's subletting clause and note any notice period or written-consent rule.
2. Send your landlord a written sublet request naming your subtenant, the term, and your temporary address.
3. Screen the subtenant with a credit check and at least one past-landlord reference.
4. Draft and sign a sublease agreement covering rent, dates, and the security deposit.
5. Collect the deposit and first month's rent before handing over keys.
6. Walk through the unit together and photograph its condition before move-in.
7. Contact a local tenant attorney or your state's housing agency if your landlord refuses consent without a clear reason.

Frequently Asked Questions

Do I need my landlord's permission to sublease my apartment?

Yes, in most cases. Most leases require written consent before you sublet, and subletting without it violates the lease even if your landlord rarely visits the property.

Can my landlord refuse to let me sublease?

Yes, but only for a specific reason in states like California and Florida, where landlords must have real grounds to say no. Elsewhere, a landlord can often refuse without giving a reason at all.

What's the difference between a sublease and a lease assignment?

A sublease is temporary and a lease assignment is permanent. Subletting keeps you as the tenant of record while someone else pays you rent; an assignment transfers your remaining lease term away entirely.

Am I still responsible for the apartment once it's sublet?

Yes. Your name stays on the original lease, so unpaid rent or damage caused by your subtenant becomes your responsibility until the landlord agrees otherwise in writing.

How much can I charge my subtenant?

Often whatever amount you and the subtenant agree to. Rent-controlled cities like New York and San Francisco cap that amount at roughly your own rent, sometimes plus a small furnished surcharge.

How much security deposit can I collect from a subtenant?

Often up to one and a half times the monthly rent, though the exact cap depends on your state. Michigan sets that specific limit under its own security deposit law.

What happens if I sublease without telling my landlord?

You risk eviction for violating your lease. Many states let you keep the unit only if the subtenant moves out quickly after a judge rules the violation against you.

Can I sublease if my lease says subletting isn't allowed?

No, not without help from local law. Some cities override an outright ban, such as New York City's rule for buildings with four or more units.

Do I need a written sublease agreement?

Yes. A signed agreement documents the rent, dates, and deposit so neither you nor your subtenant can dispute the terms later.

How long does it take a landlord to approve a sublease request?

It varies by lease and location, but rent-stabilized New York apartments must get a response within 30 days, or consent becomes automatic under the city's rules.

Can I list my apartment on a short-term rental site instead of finding a subtenant?

No, not under a standard sublease. Short-term platform rentals usually violate a lease's subletting clause and often violate separate short-term rental laws in the city.

What should I do if my subtenant stops paying rent?

Contact your landlord right away and start the process to remove the subtenant. You remain on the hook for the missed rent no matter what your subtenant does next.

Is subletting the same as adding a roommate to my lease?

No. Adding a roommate usually means signing a new lease together, while subletting creates a separate agreement with a subtenant who never signs your original lease.
