Subletting requires your landlord's written permission, a signed sublease agreement with your tenant, and clear terms about rent, duration, and who pays utilities

A sublet means you rent out your apartment to someone else while you remain on the original lease with your landlord. You are not breaking the lease — you are temporarily transferring occupancy to another person. Your landlord can refuse, allow it freely, or allow it with conditions. Many leases require written permission before you sublet; some forbid it entirely. If your lease is silent on subletting, your state's tenant law determines whether you need permission.

The person subletting from you (the subtenant) pays you rent, not the landlord. You remain responsible to your landlord for the full lease amount, for any damage the subtenant causes, and for enforcing the sublease agreement yourself. If the subtenant stops paying you, you still owe your landlord. This is the core risk of subletting: you are the middle party.

Key Takeaways

  • Check your lease for subletting rules and get your landlord's written permission before advertising or signing any sublease agreement.
  • A sublease must be in writing, signed by both you and the subtenant, and should specify rent amount, move-in and move-out dates, utilities, and house rules.
  • You remain liable to your landlord for the full lease amount and any damage, so screen the subtenant carefully and keep records of all payments.
  • Collect a security deposit from the subtenant equal to at least one month's rent, and return it within the timeframe your state law requires.
  • Inform your renters insurance and your landlord's insurance company that you are subletting, as your coverage may not protect you if the subtenant causes damage.

Check your lease and get landlord permission in writing

Before you do anything else, read your lease carefully. Look for language about subletting, assignment, or "occupancy by other parties." If the lease says subletting is prohibited, you cannot sublet legally — your only option is to ask your landlord to modify the lease or to break it (which usually costs a penalty). If the lease says you need permission, send a written request to your landlord and wait for a written response. Email counts as written permission; a text message or verbal agreement does not.

If your lease does not mention subletting, your state's tenant law fills the gap. In most states, you can sublet without permission unless the lease explicitly forbids it. However, some states require you to give notice or to offer the landlord the right to approve the subtenant. Check your state's tenant rights website or contact your local housing authority to learn the rule in your area. Do not assume silence means freedom — get clarity before you advertise.

Once you have permission, keep a copy of the email or letter granting it. If a dispute arises later, you will need proof that the landlord consented.

Create a written sublease agreement

A sublease is a contract between you and the subtenant. It must be in writing and signed by both parties. You can use a template from your state's bar association, a legal document service, or a rental platform — do not rely on a handshake or a text exchange. The sublease should include:

  • Names and contact information for you and the subtenant
  • The apartment address and unit number
  • The sublet start date and end date (must fall within your lease term)
  • Monthly rent amount and due date
  • Which utilities the subtenant pays (water, electric, gas, internet, trash) and which you cover
  • Security deposit amount and when you will return it after move-out
  • House rules: pets, guests, noise, smoking, parking
  • Who is responsible for repairs and maintenance
  • The condition of the apartment at move-in (use photos or a walk-through checklist)
  • Consequences for breaking the sublease early

The sublease rent can be higher or lower than what you pay your landlord — that is between you and the subtenant. However, if you charge significantly more than market rate and the subtenant later disputes the agreement, a court may view the sublease as unfair. Set a reasonable price and document it clearly.

Screen the subtenant and collect a security deposit

You are now acting as a landlord to the subtenant. Screen them the way a landlord would screen you: ask for references from previous landlords, verify employment or income, and run a background check if your state allows it. Many online rental platforms (Airbnb, Furnished Finder, SpareRoom) handle screening and payment processing for you, though they take a commission. If you screen independently, keep records of who you contacted and what they said.

Collect a security deposit before the subtenant moves in. The amount is typically one month's rent, though you can negotiate. Your state law sets the rules for how you hold the deposit, how much interest you must pay (if any), and how long you have to return it after move-out. Some states require you to keep the deposit in a separate account and to provide an itemized list of deductions if you keep any of it. Check your state's tenant law to avoid violating these rules — if you do, the subtenant can sue you for damages.

Keep the security deposit separate from your own money. If you mix it with your rent payments or personal funds, you may lose the legal right to keep deductions, and the subtenant may have a claim against you.

Understand your liability and insurance obligations

You remain responsible to your landlord for everything in the lease: paying rent on time, maintaining the apartment, and following all lease rules. If the subtenant damages the walls, breaks appliances, or causes a fire, your landlord will hold you liable. If the subtenant stops paying rent, you still owe your landlord the full amount. This is why screening and a written sublease matter — they are your only tools to enforce payment and behavior.

Notify your renters insurance company that you are subletting. Many policies exclude coverage if you are renting out the apartment to someone else. If the subtenant causes damage and your policy does not cover it, you will pay out of pocket. Similarly, inform your landlord's insurance company (through your landlord) that a subtenant will occupy the unit. Some landlords require the subtenant to carry their own renters insurance naming you as an interested party.

If the subtenant is injured in the apartment due to a maintenance issue (a broken stair, a gas leak), they may sue you or your landlord. Your liability depends on whether you knew about the hazard and failed to disclose it. Document the condition of the apartment at move-in with photos and a written checklist so you can prove you did not cause the damage.

Collect rent and handle move-out

Set up a clear rent payment method: a bank transfer, check, or online payment platform. Do not accept cash unless you have no other option, and if you do, get a written receipt. Keep records of every payment — a spreadsheet or bank statements are sufficient. If the subtenant misses a payment, send a written notice (email is fine) giving them a important date to pay. If they do not pay by the important date, you may need to pursue eviction through the courts, which is expensive and time-consuming. This is why screening matters: a subtenant with a history of late payments is a red flag.

As the move-out date approaches, remind the subtenant of the condition the apartment should be in and when you will conduct a walk-through. Inspect the apartment with the subtenant present if possible, take photos of any damage, and document what you are deducting from the security deposit. Provide an itemized list of deductions and return the remaining deposit within the timeframe your state requires — usually 30 to 45 days. If you do not return the deposit on time or without an itemized list, the subtenant can sue you for the deposit amount plus penalties.

Know when subletting can go wrong

Subletting breaks down most often when the subtenant stops paying rent or causes damage. If the subtenant stops paying, you have a few options: contact them to find out why, offer a payment plan, or pursue eviction. Eviction is a court process that takes weeks or months and costs money in filing fees and attorney fees. You cannot evict the subtenant yourself — you must go through the courts. If you win, the court orders them out, but collecting unpaid rent is a separate process.

If the subtenant damages the apartment beyond normal wear and tear, deduct the repair cost from the security deposit. If the damage exceeds the deposit, you can sue the subtenant in small claims court to recover the difference. However, small claims court requires you to prove the damage and its cost, so keep receipts and photos.

Another risk: your landlord can refuse to renew your lease if you sublet, even if the sublease was legal. Some landlords view subletting as a sign you are not a stable tenant. Check your lease to see if it says anything about renewal, and be aware that subletting may affect your ability to stay long-term.

Frequently Asked Questions

Can my landlord evict me if I sublet without permission?

Yes. If your lease forbids subletting or requires permission and you sublet without it, your landlord can treat it as a lease violation and begin eviction. Even if your state allows subletting without permission, your lease can override that rule. Always check your lease first and get written permission if it is required.

What if the subtenant breaks the sublease early?

That depends on what the sublease says. If it includes an early termination clause with a penalty (for example, forfeiting the security deposit or paying a month's rent), you can enforce it. If the sublease is silent, you may be able to keep the security deposit or sue for unpaid rent through the end of the sublease term. However, you have a duty to try to find a replacement subtenant to limit your losses — you cannot straightforward sit idle and demand payment.

Do I have to let the subtenant know about maintenance issues in the apartment?

Yes. You must disclose any known hazards or defects — a leaky roof, mold, broken heating, pest problems — before they move in. If you know about a problem and do not tell them, they can break the sublease, withhold rent, or sue you. Document the condition of the apartment at move-in so you can prove you disclosed everything.

Can I sublet to multiple people in different rooms?

Only if your lease and local law allow it. Some leases prohibit subletting individual rooms or limit occupancy to a certain number of people. If your lease allows it, each person in a separate room should sign a separate sublease or a co-sublease agreement. Make sure the total occupancy does not violate local housing codes, which often limit the number of unrelated people per unit.

What happens to my security deposit with my landlord if the subtenant damages the apartment?

Your landlord can deduct repair costs from your security deposit, just as they would if you caused the damage. This is why you need a security deposit from the subtenant — it is your buffer. If the subtenant's damage exceeds their security deposit, you will have to pay the difference to your landlord or sue the subtenant to recover it.
