Key Takeaways
Option A
Subletting
The temporary transfer with a safety net — for the other party.
Best for: Renters who need to vacate temporarily and plan to return to the unit before their lease ends.
Option B
Lease Assignment
The clean break — transferring your lease entirely to someone else.
Best for: Renters who want to exit a lease permanently before its end date without continuing financial responsibility.
If you're relocating temporarily and want to return to your apartment
Subletting
Subletting lets you keep your lease intact and your right to return, while a subtenant covers your rent during your absence.
If you're moving permanently and want no further financial obligation
Lease Assignment
Assignment transfers your full lease to a new tenant and, when landlord-approved, typically removes you from ongoing liability.
If your lease has favorable rent terms worth preserving for someone else
Lease Assignment
The incoming tenant takes over your existing lease terms, including your rent rate, which can be attractive in rising-rent markets.
If your landlord will not approve a full assignment but permits subletting
Subletting
Some landlords allow subletting more readily than assignment — though you must understand the financial risk you're retaining.
The Core Legal Distinction
Both subletting and lease assignment involve replacing yourself — at least temporarily — with another occupant. But legally, they operate very differently, and the distinction can have serious financial consequences.
In a sublet, you (the original tenant) remain a party to the lease. You're essentially becoming a landlord yourself: you rent to a subtenant, who pays you, and you remain responsible to your landlord for rent, property condition, and lease compliance. If your subtenant stops paying or damages the unit, your landlord can still come after you.
In a lease assignment, you transfer your entire lease interest to a new tenant — the assignee. If your landlord agrees and signs off on releasing you, you step out of the picture entirely. The assignee steps into your shoes, takes over your lease terms, and becomes directly responsible to the landlord.
This fundamental distinction — retained liability versus transferred liability — is what makes the choice matter so much. Before signing any lease, it's worth understanding these dynamics. See our guide to what first-time renters need to know for more on reading lease clauses carefully.
| Criterion | Subletting | Lease Assignment |
|---|---|---|
| Original tenant's liability | Remains fully liable to landlord | Released upon landlord approval |
| Duration | Temporary; tenant intends to return | Permanent transfer for lease remainder |
| Relationship to landlord | Subtenant pays you; you pay landlord | Assignee pays landlord directly |
| Landlord consent | Typically required | Typically required |
| Best use case | Short-term absence with return planned | Permanent departure from the unit |
| Risk to original tenant | High — ongoing exposure to subtenant issues | Lower — exits lease when approved |
Landlord Approval: A Non-Negotiable Step
Most standard leases require landlord consent before you can sublet or assign — and skipping this step is one of the most common and costly mistakes tenants make. Proceeding without approval can constitute a material lease violation, potentially triggering eviction proceedings against you and the person you brought in.
State laws add another layer. Some states — New York is a well-known example — give tenants in buildings of a certain size a statutory right to sublet with landlord approval, meaning the landlord cannot unreasonably withhold consent. Other states are far more permissive toward landlords. Always check the law in your specific state and municipality before assuming your lease clause is the final word.
Security Deposit Considerations
In a sublet arrangement, the original tenant's security deposit typically stays with the landlord. As the sublessor, you may choose to collect a separate deposit from your subtenant — but this is a private arrangement between you and them, not the landlord. In an assignment, the original deposit may be transferred or returned and replaced by the assignee's deposit, depending on what the landlord requires. Clarify deposit handling in writing before any transition.
When seeking approval, present your landlord with a proposed subtenant or assignee who is financially qualified — similar credit and income profile to what was originally required of you. Landlords are more likely to approve a transition that doesn't increase their risk.
When Each Option Makes Sense
Subletting is appropriate when your departure is temporary. If you're taking a six-month work assignment in another city, traveling for an extended period, or handling a family situation that requires you to be elsewhere, subletting lets you hold your place — literally. The downside is ongoing exposure: you're liable until you return and your subtenant vacates.
Lease assignment makes more sense when you're done with the unit and want a clean break. Job relocation, a move to a new city, or a life change that makes returning unlikely are all scenarios where assignment is the practical choice. Because your lease terms transfer with the assignment — including your rent rate — an assignment can be attractive to incoming tenants in competitive rental markets where rents have risen since your lease was signed.
Understanding which lease structure you're in also matters. Fixed-term leases generally lock in terms that make both subletting and assignment more relevant discussions. For context on how lease structures compare, see our breakdown of month-to-month vs. fixed-term leases.

A significant number of US states have specific laws governing subletting rights, though scope and tenant protections vary considerably by jurisdiction.
What to Do Before You Commit to Either Path
Start by reading your lease carefully. Look for clauses that address subletting, assignment, and landlord consent requirements. Note any fees, notice periods, or conditions attached to approval requests.
Next, consult your state's tenant rights statutes or a local tenant advocacy organization — many provide free guidance. If you're unsure whether your landlord is permitted to refuse your request, a brief consultation with a tenant's rights attorney can clarify your options without significant cost.
Document everything in writing: your request to the landlord, their response, any approval conditions, and the terms agreed upon with your subtenant or assignee. A verbal approval is difficult to enforce if a dispute arises later.
Finally, if you are approaching the end of your lease and weighing whether to renew or transition out, the dynamics around renewal also deserve attention. Our guide to lease renewal and rent increases explains your rights when a lease term is ending.
