A sublet is a rental arrangement in which a tenant rents out all or part of their leased home to someone else while keeping their own name on the original lease. The tenant stays legally responsible to the landlord for rent and the condition of the property, even though a new person has moved in. Sublets usually come up when someone needs to leave temporarily for a job, school, or personal reason and doesn’t want to break the lease and lose the apartment.
Who’s Involved and Who Owes What
Every sublet has three people in it. The original tenant, sometimes called the sublessor, is the one who signed the lease with the landlord. The sublessee is the new occupant renting from that tenant. The landlord owns the property and holds the master lease. What makes a sublet different from an ordinary rental is the chain of responsibility: the sublessee pays rent to the sublessor, and the sublessor remains on the hook to the landlord for everything in the original lease. The landlord and the sublessee have no direct contract with each other.1Legal Information Institute. Sublease
That structure matters in practice. If the sublessee stops paying or damages the unit, the landlord comes after the original tenant, not the sublessee. The original tenant then has to chase the sublessee separately for reimbursement. This layered accountability is both the defining feature of a sublet and its biggest risk for the person doing the subletting.
Sublet or Lease Assignment?
People often mix up subletting with assigning a lease, but they work differently in one important way. When you sublet, you stay on the original lease and sit between the landlord and the new occupant. When you assign a lease, you transfer your entire interest to someone else, and the new tenant steps into your shoes with a direct relationship to the landlord.1Legal Information Institute. Sublease
With an assignment, the original tenant is typically released from future obligations once the new tenant takes over. With a sublet, the original tenant keeps all those obligations. If you’re leaving permanently, an assignment is usually cleaner. If you plan to come back to the same apartment, a sublet makes more sense.
Common Forms a Sublet Can Take
Sublets take several shapes depending on what the tenant needs:
- Full-unit sublet, where the tenant moves out entirely and the sublessee occupies the whole space for a set period. This is the most common arrangement when someone relocates temporarily.
- Partial sublet, where the tenant rents out one bedroom while continuing to live in the unit. Typical in multi-bedroom apartments when a roommate leaves.
- Short-term sublet, covering a few weeks or months, often over a summer or during a temporary assignment.
- Long-term sublet, spanning several months up to the remaining term of the original lease.
A sublease cannot last longer than the time remaining on the original lease. One that lasts the full remaining term starts to look like an assignment in practice, though legally the original tenant’s obligations stay in place unless the landlord agrees otherwise.
Does Your Lease Allow Subletting?
Before anything else, read your lease. Most residential leases either prohibit subletting outright or require written landlord consent. If consent is required and you sublet anyway, that’s a lease violation and can lead to eviction.
If the lease is silent on the question, the default rule in most jurisdictions is that you have the right to sublet. Relying on that silence is risky, though. Landlords who didn’t anticipate the possibility may object, and local rules vary enough that getting written approval is the safest route regardless of what the lease says.
Make the request in writing. Include the proposed sublessee’s name, the dates, and anything else the lease requires. Some jurisdictions put a deadline on the landlord’s response, and failure to respond within that window may count as consent. Others give landlords broad discretion. Either way, documenting the approval protects you if the landlord later claims they never agreed.
When a Landlord Can Say No
In many jurisdictions, a landlord required to consider a sublet request can’t refuse arbitrarily. Reasonable grounds for denial generally include the proposed sublessee’s inability to afford the rent, a poor rental history, occupancy that would exceed the unit’s legal capacity, or a plan to use the space for purposes not permitted under the lease. A refusal with no stated reason may not hold up where local law requires landlords to act reasonably. But if the lease flatly prohibits subletting and local law doesn’t override that, the landlord can simply say no.
What Goes in the Sublease Agreement
The sublease is the contract between the original tenant and the sublessee. It doesn’t replace the original lease; it sits on top of it. The sublessee should get a copy of the original lease, because they’ll be bound by its terms even without signing it. A solid sublease covers:
- Full legal names and contact information for both parties.
- The exact property address, including specific rooms if it’s a partial sublet.
- Start and end dates, which must fall within the remaining term of the original lease.
- Rent amount, due date, payment method, and any late fees.
- Security deposit amount, where it will be held, and conditions for its return. Deposit limits vary by jurisdiction, typically ranging from one to three months’ rent.
- Which party pays for utilities such as electricity, water, and internet.
- A clause stating the sublessee agrees to follow all terms of the original lease.
One question comes up often: can you charge the sublessee more than you pay in rent? In most places, yes. There’s no general prohibition on profiting from a sublet. The exception is rent-controlled or rent-stabilized housing, where local regulations often cap the price. If your unit is subject to rent regulation, check local rules before setting an amount.
Screening the Sublessee
When you sublet, you’re effectively acting as a landlord, and the screening responsibilities come with the role. A sublessee who doesn’t pay or wrecks the place leaves you holding the bag with your own landlord. At minimum, check credit, verify income, and talk to previous landlords.
Fair housing rules apply to you too. Federal law prohibits discrimination in rental housing based on race, color, religion, sex, national origin, familial status, and disability.2Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices Many state and local laws add other protected classes. Keep your screening focused on financial ability and rental history, not personal characteristics.
Handing Over the Keys
Once the sublease is signed and the landlord’s written approval is in hand, the final steps are mostly logistical: the sublessee pays the deposit and first month’s rent, keys change hands, and the sublessee takes possession.
Before that happens, do a walk-through together and document the condition of every room. Photograph or video the walls, floors, appliances, fixtures, windows, and any existing damage. Both parties should sign a written condition report. HUD publishes a standard move-in inspection form that works well as a template.3U.S. Department of Housing and Urban Development. Move-In/Move-Out Inspection Form This record is what protects you at deposit-return time and what protects the sublessee from being charged for damage that was already there.
The Insurance Gap
Something that catches both sides off guard: the original tenant’s renters insurance does not cover the sublessee. The sublessee’s belongings and personal liability are unprotected unless they buy their own policy. If there’s a fire, a break-in, or an injury in the unit, the sublessee has no coverage under the sublessor’s policy.
Require the sublessee to carry renters insurance as a condition of the sublease. The sublessor’s own policy may also need updating, since some insurers treat a sublet as a change in occupancy that affects coverage. A quick call to your insurer before finalizing anything avoids unpleasant surprises.
What You Owe in Taxes
Rent you collect from a sublessee is taxable income. You report it on Schedule E of your federal tax return, which covers supplemental income from rental real estate.4Internal Revenue Service. Instructions for Schedule E (Form 1040) This applies even if you’re just trying to cover your own rent while away.
There’s one exception. If you rent your home for fewer than 15 days during the year, you don’t report the rental income at all, and you can’t deduct any rental expenses either.5Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property This is sometimes called the 14-day rule. For sublets of two weeks or less in a calendar year, it can mean tax-free income.
For longer sublets, you can offset the income with deductible expenses: the portion of your rent that corresponds to the sublet period, utilities you continue to pay, and repairs or maintenance during the sublessee’s stay. Expenses have to be divided between personal and rental use based on the number of days the unit was rented versus the days you used it yourself.5Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property In most cases, rental expenses cannot exceed gross rental income.
When Things Go Wrong
The most common sublet problem is a sublessee who stops paying. Because your name is on the original lease, the landlord expects rent from you whether the sublessee pays or not. You cover the gap out of pocket and chase the sublessee for what they owe.
If the sublessee refuses to leave, you have to initiate eviction yourself, using the same legal process a landlord would: written notice, a waiting period, and if necessary a court filing. You cannot change the locks or remove their belongings.
Property damage works the same way. The landlord holds you responsible for the condition of the unit and deducts from your deposit. You then recover from the sublessee’s deposit or, if that isn’t enough, through other means.
The worst case is subletting without permission. If your lease requires consent and you sublet without it, the landlord can treat it as a lease violation. Consequences range from a warning to eviction of both you and the sublessee, depending on the lease and local law. Some jurisdictions also let landlords pursue financial damages if the unauthorized sublet generated income above the original rent. The way to avoid all of this is the same thing that prevents most landlord-tenant disputes: get everything in writing before anyone moves in.
