What Subletting Actually Means
When a tenant sublets their unit, they become a kind of middle landlord. The original tenant — now called the sublessor — collects rent from a subtenant and remains fully responsible to the actual landlord for everything the original lease requires: rent, property condition, and lease compliance.
This arrangement is common when a tenant needs to travel for several months, relocates temporarily for work, or simply needs help covering rent. The subtenant lives in the space and pays the sublessor, but the landlord's legal relationship remains with the original tenant. That distinction matters significantly: if the subtenant damages the unit or stops paying, the original tenant is still on the hook.

Read Your Lease Before Anything Else
Before approaching your landlord or making any arrangements with a potential subtenant, locate the subletting or assignment clause in your lease. It will tell you whether consent is required, what the approval process looks like, and whether there are any fees involved. This step alone can save you from a serious lease violation.
How Lease Assignments Work Differently
A lease assignment is a more complete transfer. Rather than stepping in as an intermediary landlord, the original tenant hands over their entire interest in the lease to a new person — the assignee. Once a landlord formally accepts the assignment, the assignee steps into the original tenant's shoes, responsible directly to the landlord for rent and all lease obligations.
This makes assignment a practical option for tenants who need to exit a lease permanently without going through formal lease-breaking procedures. It's worth noting that some leases include language holding the original tenant secondarily liable even after an assignment — meaning if the new tenant defaults, the landlord might still come after the original signer. Reading the lease carefully and confirming terms in writing is essential before proceeding.
If exiting a lease is your primary concern, the consequences of breaking a lease early are worth reviewing alongside your assignment options.

Survey data from various tenant advocacy organizations suggests that early lease exits — including subletting and assignment — are a common real-world need for American renters.
When You Need Landlord Approval — and How to Ask
The majority of standard lease agreements contain clauses that prohibit subletting or assignment without prior written consent from the landlord. Ignoring this requirement is a serious risk: unauthorized subletting is a lease violation that can lead to eviction of both the original tenant and the subtenant.
That said, tenant protections vary significantly by state and city. In some jurisdictions, landlords cannot unreasonably withhold consent for a sublet or assignment — meaning they must have a legitimate reason for refusal, such as the proposed subtenant failing a standard background check. In other states, landlords have broad discretion to say no.
When requesting approval, put it in writing. Submit a formal letter or email that identifies the proposed subtenant or assignee, explains the reason for the request, and includes supporting information about the incoming tenant (such as income verification or references). Document every communication. If the landlord approves, get that approval in writing before the new tenant moves in.

Protecting Yourself Regardless of Which Route You Choose
Whether you're subletting or assigning, a written agreement is non-negotiable. A sublease agreement should spell out the rental term, monthly rent, security deposit handling, house rules, and what happens if either party violates its terms. It should explicitly reference the original lease and confirm that the subtenant agrees to abide by its conditions.
Keep records of rent payments from your subtenant. Conduct a documented walkthrough before and after the sublease period. If you've collected a security deposit from a subtenant, understand that you may still owe your original deposit to the landlord — and recovering funds from a subtenant who causes damage can be complicated.
For context on how security deposits are regulated and what landlords can lawfully deduct, see what landlords can legally keep from a security deposit.
Local Law Can Override Your Lease
In cities like New York and San Francisco, tenant protection laws give renters the right to sublet under certain conditions — even if the lease says otherwise. If you live in a jurisdiction with strong tenant protections, it's worth consulting a local tenant rights organization or attorney to understand exactly what your lease can and cannot legally restrict.
