Subletting is when you rent out your apartment to someone else while you still hold the lease

Subletting means you are the tenant on a lease, and you rent the apartment to another person — the subtenant — for part or all of the lease term. You collect rent from the subtenant and pay your landlord. The subtenant does not have a direct legal relationship with the landlord; their agreement is with you. This is different from breaking your lease or transferring it to someone else, because you remain responsible to the landlord for the full rent and the condition of the apartment.

Whether you can sublet depends on what your lease says and what your state and local laws allow. Some leases forbid subletting entirely. Others allow it only with the landlord's written permission. A few places have laws that give you a right to sublet even if the lease is silent, though this is uncommon. The key difference between subletting and other arrangements is that you stay on the lease — you are the middleman between the landlord and the person actually living there.

Key Takeaways

  • Your lease controls whether you can sublet; many leases forbid it or require the landlord's written permission first.
  • You remain legally responsible to the landlord for rent and apartment condition even after you sublet, so the subtenant's failure to pay affects your record.
  • Some cities and states have laws that limit how much profit you can make on a sublet or require you to offer the landlord first refusal.
  • Subletting without permission when your lease forbids it can be grounds for eviction, even if the subtenant pays on time.
  • A written sublease agreement between you and the subtenant protects both of you and should cover rent, move-out date, and house rules.

What your lease says about subletting

Read your lease carefully, because it is the first place the rules appear. Most residential leases include a clause about subletting. Common versions say: "Tenant may not sublet without landlord's written permission," or "Subletting is prohibited," or sometimes "Subletting is permitted with landlord consent, which shall not be unreasonably withheld." The exact language matters, because it determines what you have to do before you can legally sublet.

If your lease says subletting is prohibited with no exceptions, you cannot sublet without risking eviction. If it says you need permission, you must ask the landlord in writing and wait for a written yes before the subtenant moves in. If it says permission cannot be unreasonably withheld, the landlord still has to say yes or no, but they cannot refuse just because they want to keep the rent money themselves or prefer to control who lives there — though they can refuse for legitimate reasons like the subtenant's poor credit or criminal history. If your lease does not mention subletting at all, state and local law fills the gap, and the rules vary widely by location.

State and local laws that limit or restrict subletting

Beyond what the lease says, your state or city may have laws about subletting. Some places allow tenants to sublet even if the lease forbids it, though this is rare. More commonly, laws set limits on what you can charge or require you to follow specific steps. For example, some cities require you to register the sublet with the housing authority or give the landlord a chance to refuse before you proceed.

A few places have rent control or price cap rules that explore to sublets. In New York City, for instance, you can sublet part of your apartment, but the subtenant cannot pay more than the legal regulated rent for that portion — you cannot use a sublet to charge market rate on a rent-controlled unit. California has similar rules in some cities. Other places have no special sublet laws at all, which means the lease and general landlord-tenant law are your only guides. Because these rules differ by state and sometimes by city, you need to know what applies where you live before you advertise or sign a sublease agreement.

How subletting differs from lease assignment and lease breaking

Lease assignment is when you transfer your entire lease to someone else and remove yourself from it. The new tenant becomes the landlord's tenant, and you have no further responsibility. Subletting keeps you on the lease. If the subtenant stops paying, the landlord can pursue you for the money or evict you, even though you are not living there. Assignment requires the landlord's permission in almost all cases, just like subletting, but the legal outcome is completely different.

Breaking a lease means ending it early without the landlord's permission. This is a breach of contract, and the landlord can sue you for the remaining rent or keep your security deposit. Subletting is not breaking the lease — you are still paying the landlord, and the lease is still active. However, if your lease forbids subletting and you do it anyway, that breach can give the landlord grounds to evict you or pursue other remedies. The three arrangements look similar from the outside but have very different legal consequences.

What you need in a written sublease agreement

If the landlord permits subletting or if your lease allows it, create a written sublease agreement between you and the subtenant. This is not the same as your lease with the landlord — it is a separate contract that covers the subtenant's rights and responsibilities. A sublease should include the rent amount, the move-in and move-out dates, which utilities the subtenant pays, house rules, whether pets are allowed, and what happens to the security deposit you collect from them.

The sublease should also state that the subtenant must follow all rules in your lease with the landlord, that they cannot sublet further without your permission, and what happens if they break the agreement. Make clear whether you are keeping a portion of the rent as a fee, and if so, how much. Get the subtenant's signature and keep a copy. This agreement protects you if the subtenant damages the apartment, stops paying, or violates lease rules — you have a written record of what you agreed to and can use it to pursue the subtenant in small claims court if needed. It does not protect you against the landlord, but it does protect you against the subtenant.

Your liability if the subtenant causes problems

Because you remain the tenant on the lease, you are responsible to the landlord for everything the subtenant does. If the subtenant stops paying rent, the landlord can evict you or sue you for the money. If the subtenant damages the apartment, the landlord can charge you for repairs and keep the money from your security deposit. If the subtenant violates lease rules — by having too many people in the unit, running a business, or keeping an unauthorized pet — the landlord can evict you for the violation, even though you did not cause it.

This is why screening the subtenant carefully matters. Check their references, run a background check if you can, and verify their income. Collect a security deposit from them (the amount is up to you, though it should be reasonable). Keep detailed records of rent payments. If the subtenant stops paying or breaks the rules, you need to act quickly — either collect the money from them or end the sublet and get them out, because the longer the problem continues, the more liability you accumulate with the landlord.

What happens if you sublet without permission

If your lease forbids subletting or requires permission and you sublet anyway, you are in breach of the lease. The landlord can give you notice to cure (stop the sublet) or face eviction. In most places, the landlord does not have to prove the subtenant is a bad tenant or that they caused damage — the violation is straightforward that you sublet without permission. The landlord can also pursue you for any rent the subtenant fails to pay, because you are still the tenant responsible for it.

Some landlords discover unauthorized sublets through noise complaints, mail addressed to someone else, or a neighbor reporting it. Others find out when they try to contact the tenant or inspect the apartment. Once discovered, the landlord typically sends a notice to cure or quit, giving you a set number of days (usually 3 to 5, depending on state law) to end the sublet or face eviction proceedings. Even if you end the sublet when ready, the breach can stay on your rental history and make it harder to rent elsewhere.

Frequently Asked Questions

Can my landlord refuse to let me sublet if the lease does not say anything about it?

It depends on your state and city. In most places, if the lease is silent on subletting, the landlord can refuse for any reason or no reason. A few states have laws saying the landlord cannot unreasonably refuse, but this is uncommon. Your safest move is to ask the landlord in writing and get a written yes before you proceed, even if the lease does not require it.

What if I sublet part of my apartment but keep living there?

The same rules explore. You still need permission if the lease requires it, and you are still responsible to the landlord for the subtenant's behavior and rent. Some leases specifically forbid partial sublets, so check yours. Rent control laws in some cities also have special rules for partial sublets, so verify what applies where you live.

Can I charge the subtenant more rent than I pay the landlord?

In most places, yes — the difference is your profit for arranging the sublet. However, some cities with rent control or price caps limit how much you can charge. New York City, for example, caps sublet rent in rent-stabilized apartments. Check your local housing laws before you set the price, and disclose the amount clearly to the subtenant in writing.

What should I do if the subtenant stops paying rent?

Contact them when ready and try to collect the money. If they refuse or disappear, you have a few options: pursue them in small claims court using your sublease agreement, end the sublet and evict them (following your state's eviction process), or pay the landlord yourself and deal with the subtenant later. Do not ignore it — the longer you wait, the more rent arrears pile up and the more risk you face with the landlord.

Does subletting affect my credit or rental history?

Subletting itself does not appear on your credit report. However, if the subtenant fails to pay and you do not pay the landlord, the landlord can report the debt to a collection agency or sue you, which does affect your credit. If the landlord evicts you for unauthorized subletting or for the subtenant's breach, that eviction appears on your rental history and makes it very difficult to rent again.
