Subletting and Assignment: Getting Permission Properly

Handing your apartment to someone else comes in two shapes, and choosing the wrong one is expensive. A sublease means you keep your lease and stay liable to the landlord while a subtenant pays you. An assignment transfers the whole remaining term to a new tenant who then deals directly with the landlord — though you usually stay secondarily liable unless the landlord expressly releases you in writing. Nearly every residential lease requires the landlord's written consent for either one. The right move is to ask in writing, in advance, and to keep the paper.

Everything past that distinction is state and city law. Some states impose a "not unreasonably withheld" standard on consent, some leave the landlord free to refuse for any reason, and a few give tenants an affirmative right to sublet with a defined procedure. Cities layer on their own rules, particularly about short stays. Nothing here is a national rule or a deadline you can rely on — check your own state statute and city housing agency.

The two structures, and what each one costs you

Under a sublease you remain the tenant. Your name is still on the lease, you still owe the rent, and the subtenant owes you. If the subtenant stops paying or damages the unit, the landlord looks to you. The advantage is control and reversibility: the arrangement can be short, you keep your tenancy, and you can return at the end. This is the usual choice for a semester abroad, a temporary work posting or a few months away.

Under an assignment the entire remaining term moves to the assignee, who becomes the landlord's tenant and pays rent directly. The advantage is that you are leaving for good. The catch is the one people miss: transferring the term does not automatically end your liability. In most places the original tenant stays secondarily liable on the contract unless the landlord signs a release — often called a novation. If your goal is a clean exit, the release is the document that matters, not the assignment itself.

Worth knowing: Ask for the release in the same conversation as the assignment, not afterward. Once the landlord has an acceptable new tenant in place, the incentive to sign a release for the old one drops considerably. The sentence you want states that you are discharged from all future obligations under the lease as of the transfer date.

A third structure is sometimes the better fit: adding the new person as a co-tenant while you also remain on the lease, or simply having them replace you through a lease amendment. That path shifts the liability question into the joint-and-several rules discussed in our guide on roommates, co-tenants and who owes the rent. Whichever structure you use, read the lease's own transfer clause first — our walkthrough on reading a residential lease before signing shows where it usually sits and what language to look for.

What your lease says, and what your state adds on top

Start with the lease. Transfer clauses come in roughly three flavors: an absolute bar on subletting or assignment, a consent requirement with no standard attached, or a consent requirement stating that consent will not be unreasonably withheld. Then check your state, because state law can change the effect of all three, and the picture as of mid-2026 varies widely. In several states a bare consent clause is read to carry a reasonableness standard by statute or case law. In a few, tenants have an affirmative statutory right to sublet, with a request procedure, a response window and consequences if the landlord ignores it. Elsewhere, a flat refusal is permitted and the tenant's realistic options are negotiation or an early-termination payment.

New York City, as one clearly labeled example, has long had a statutory sublet procedure for certain buildings that sets out how the tenant asks and how the landlord must respond. That is a state statute applying to a particular class of buildings, not a description of what happens elsewhere. Do not assume any comparable right exists where you live until you have read your own state's law. Cornell's overview of landlord-tenant law and its entry on leases are useful orientation before you look up the statute itself.

Careful: Short-term rental platforms are a separate legal problem from ordinary subletting. Many cities restrict or ban rentals under a set number of nights, require registration or a permit, and impose per-night penalties on the host. Condominium and co-op rules often prohibit short stays outright. A landlord's consent to sublet does not override a city ordinance, and hosting without checking can produce both a lease-violation notice and a municipal fine.

Two related checks are worth making before you market the space. Confirm that the unit is a legal dwelling in the first place, since transferring an unlawful unit compounds the problem — see illegal units, basement apartments and certificates of occupancy. And confirm how much term you actually have left, because a sublease cannot outlast your own lease; what happens at the end of a term is covered in lease renewal, non-renewal and month-to-month conversion.

How to make the request

Put it in writing, send it the way the lease requires notices to be sent, and keep proof of delivery. A vague text message is not a request; it is something the landlord can later say never happened. A complete request also removes the easiest grounds for refusal, because a landlord who has the information cannot claim to be evaluating an unknown.

• Your name, unit, and the exact dates of the proposed sublease or the effective date of the assignment.
• The proposed person's full name, employment or income information, and consent to a background or credit check.
• References, including a prior landlord where one exists.
• The rent the subtenant will pay you, and confirmation that it does not exceed what your lease or local law permits.
• How many people will occupy the unit, checked against the occupancy limit.
• Your forwarding address and a statement of who remains responsible for rent during the period.
• A request for written consent, and a request for a written release if you are assigning.

1. Day one

   Send the written request by the notice method the lease specifies, and keep the receipt, certified mail slip or delivery confirmation.

2. Within the lease or statutory window

   The landlord responds. Some leases set a response period; a few states set one by statute and attach consequences to silence. Where neither exists, a reasonable time is the practical standard.

3. If information is requested

   Supply it promptly and in writing. An incomplete application is the most common and most defensible reason to say no.

4. On consent

   Get it signed. Then sign the sublease or assignment, do a documented walk-through with photographs, and confirm insurance and utilities.

5. On refusal or silence

   Ask for the reason in writing, evaluate it against your state's standard, and decide whether to propose another candidate, negotiate an early termination, or seek advice.

Reasonable objections, refusals, and the cost of skipping consent

Where a reasonableness standard applies, courts generally accept objections grounded in the proposed occupant's suitability: weak credit or income relative to the rent, poor references, a history of nonpayment, more occupants than the unit lawfully holds, or a proposed use that breaks the lease or local law. Objections that tend to fail are the arbitrary ones — refusal without any stated reason, refusal to force the tenant to stay and keep paying, or refusal used to extract a higher rent where the law does not permit the increase. Refusal on a protected characteristic is a fair housing matter entirely, and complaints go to HUD or a state or local civil rights agency.

If the answer is no and the reason looks unreasonable, the usual next steps are to ask for the refusal in writing, to propose a second qualified candidate, and to document everything. Some states treat an unreasonable refusal as releasing the tenant from the lease or as a defense; others do not, and going ahead anyway is a lease violation. Subletting without consent typically produces a notice to cure, then an eviction case, and in a regulated tenancy it can mean losing a below-market unit that is very hard to replace. If the subtenant creates disturbances, the landlord may also frame the problem as a nuisance, which is a separate ground.

Two practical points get forgotten. First, insurance: your renters policy may not cover a person who is not named on it, and a landlord's policy covers the building, not anyone's belongings. Have the subtenant carry their own policy and confirm your carrier's position in writing. Second, taxes: rent you collect from a subtenant is generally income. Ask a tax professional rather than guessing, and keep records of what you collected and what you paid. Agency directories are indexed at USA.gov.

Finally, write an actual sublease. Verbal arrangements between friends are the ones that produce disputes, because nothing can be pointed to when the departure date, the deposit or the utility bill is contested.

• Names of tenant and subtenant, the unit, and the precise start and end dates.
• Rent amount, due date and payment method, plus who pays which utilities.
• Any deposit the subtenant pays you, where it is held and how it is returned.
• A statement that the sublease is subject to the master lease, with a copy attached.
• Condition documentation: a signed inventory and dated photographs at move-in and move-out.
• What happens if the master lease ends early, and the subtenant's duty to vacate on the end date.
• The landlord's written consent, attached to the sublease.

Common questions

The landlord never answered my written sublet request. Does silence count as approval?

Only where a statute or your lease says so. A few states attach consequences to a landlord's failure to respond within a stated window, sometimes treating silence as consent for the specific procedure the statute describes. Most places do not. Assuming approval from silence is risky, because if you are wrong you have committed a lease violation. Send a second written request noting the first, keep proof of delivery, and get advice before moving anyone in.

Can I charge my subtenant more than I pay in rent?

Sometimes, but check carefully. Some leases prohibit profiting on a sublet, and some jurisdictions — particularly those with rent regulation — cap what a subtenant may be charged and treat overcharging as a serious violation that can cost the tenant the apartment. Where nothing restricts it, a modest premium for a furnished unit is often accepted. Confirm your lease language and your local rules in writing before setting the rent.

If I assign my lease, am I finally free of it?

Not automatically. An assignment moves the remaining term to the assignee, but in most places the original tenant stays secondarily liable on the contract. If the assignee defaults, the landlord can come back to you. The document that ends your exposure is a written release, sometimes called a novation, signed by the landlord and stating you are discharged from future obligations. Negotiate it at the same time as the assignment.

My subtenant will not leave at the end of the agreed period. What now?

You cannot change the locks or remove their belongings; self-help removal is prohibited in most states even when the person clearly overstayed. Depending on your state, a holdover subtenant is removed through a court proceeding, and you as the tenant may be the one who has to bring it. This is exactly why the end date, the obligation to vacate and the deposit terms belong in a signed sublease rather than a friendly understanding.
