A residential sublease agreement is a contract between an existing tenant (the sublessor) and a new occupant (the subtenant) under which the subtenant rents all or part of a leased property for a period within the original lease term.
Unlike a lease assignment, a sublease keeps the original tenant on the hook. The sublessor remains fully liable to the landlord under the original lease even after the subtenant moves in. This distinction has major financial and legal consequences for both the sublessor and subtenant.
What Is a Residential Sublease Agreement?
A sublease, also called a sublet, occurs when a tenant who has a signed Residential Lease Agreement with a landlord rents the same space to a third party for some or all of the remaining lease term
Three parties are involved in a sublease arrangement:
- Landlord (lessor): The property owner or management company that is party to the original lease. The landlord is typically not a party to the sublease agreement itself, but their consent is usually required for the sublease to be valid.
- Original tenant (sublessor): The person on the original lease who is renting to the subtenant. The sublessor remains legally bound to the landlord under the original lease, regardless of what the sublease agreement says.
- Subtenant (sublessee): The new occupant who rents from the sublessor under the sublease agreement. The subtenant has rights against the sublessor but generally has no direct legal relationship with the landlord.
Sublease vs. Assignment of Lease: A Critical Distinction
Subleases and Agreement Assignments are both ways for a tenant to transfer occupancy rights, but they differ fundamentally in who remains liable.
The bottom line: in a sublease, the original tenant never escapes liability to the landlord. If the subtenant stops paying rent, the landlord can demand payment from the sublessor. In a lease assignment where the landlord releases the original tenant, the original tenant is no longer responsible.
Does the Landlord Have to Consent to a Sublease?
In most states, a tenant cannot sublease without the landlord's consent unless the lease expressly permits subleasing without approval.
State law governs whether landlords can unreasonably withhold consent. In some states, landlords have broad discretion to refuse any sublease request. In other cases, landlords must provide a reason for refusal and cannot unreasonably withhold consent.
Always check your original lease and your state's current landlord-tenant law before subleasing. Local ordinances (especially in major cities) may provide additional tenant rights.

What to Include in a Sublease Agreement
- Identification of parties: Full legal names and contact information for the sublessor, subtenant, and (if applicable) landlord.
- Property description: Full address of the rental unit, including apartment number. If only a portion of the unit is being subleased (a single room, for example), clearly describe the space the subtenant will occupy and any shared areas.
- Sublease term: Start and end dates of the sublease. The sublease cannot extend beyond the original lease term.
- Monthly rent: The amount the subtenant will pay the sublessor each month, the due date, and the method of payment. Note: the sublessor is still responsible for paying the full rent to the landlord regardless of whether the subtenant pays.
- Security deposit: Whether the sublessor will collect a security deposit from the subtenant, the amount, and the conditions for its return. This is separate from any deposit the sublessor holds with the landlord.
- Original lease terms: Reference to and incorporation of the original lease. The subtenant is typically bound by the same rules as the original tenant, including pet policies, noise rules, and parking restrictions.
- Landlord consent: Attach the landlord's written consent to the sublease, or reference that consent has been obtained.
- Utilities: Which utilities are included in the subrent and which are the subtenant's responsibility.
- Sublease-specific rules: Any additional rules that apply specifically to the sublease arrangement, such as guest policies, use of common areas, or move-in/move-out procedures.
- Default and remedies: What happens if the subtenant fails to pay rent or violates the sublease. The sublessor's remedies against the subtenant include the same eviction rights a landlord would have against a tenant.
- Early termination: Whether either party can terminate the sublease early and the notice required to do so.
- Signatures: Both the sublessor and subtenant must sign. The landlord's signature is not usually required on the sublease itself, but their separate written consent to the sublease should be obtained.
How to Sublease an Apartment: Step by Step
- Review your original lease to determine whether subleasing is permitted, prohibited, or requires landlord consent.
- If consent is required, submit a written sublease request to your landlord with your proposed subtenant's information (name, proposed move-in date, and duration of sublease).
- Screen your subtenant. Run a credit and background check and verify their income. You remain liable to the landlord, so the subtenant's reliability matters directly to you.
- Obtain the landlord's written consent before the subtenant moves in.
- Draft the sublease agreement covering rent, term, deposit, rules, and default remedies.
- Both parties sign the sublease agreement.
- Collect the security deposit and first month's rent from the subtenant before handing over keys, and provide a Rent Receipt to document all payments.
- Provide the subtenant with a copy of the original lease so they understand the rules they are bound by.
- Document the condition of the unit with photos or video before the subtenant moves in.
- Continue making your full rent payment to the landlord on time each month, regardless of whether the subtenant pays you.
Risks for the Sublessor (Original Tenant)
As the sublessor, you carry significant financial and legal exposure that does not disappear just because someone else is living in the unit.
- Rent liability: You remain obligated to pay the landlord the full rent each month. If the subtenant does not pay you, you must still pay the landlord or face eviction under the original lease.
- Property damage liability: If the subtenant damages the unit, the landlord can hold you responsible. You may be able to recover damages from the subtenant, but you must settle with the landlord first.
- Lease violation liability: If the subtenant violates the original lease terms (unauthorized pets, excessive noise, illegal activity), the landlord can pursue eviction against you, not just the subtenant.
- Difficulty removing a non-paying subtenant: Even though the subtenant rents from you, removing a subtenant who stops paying or refuses to leave typically begins with a Notice to Pay Rent or Quit and may require a formal eviction proceeding in the county where the property is located.
- End-of-lease complications: If the original lease ends while a sublease is in force, the subtenant may need to vacate. Plan the sublease term carefully to avoid this conflict.
Risks for the Subtenant
Subtenants enjoy fewer legal protections than direct tenants in many states.
- No direct relationship with the landlord: The subtenant's contract is with the sublessor, not the landlord. If the sublessor stops paying rent or violates the original lease, the landlord may evict the sublessor and, in the process, require the subtenant to vacate even if the subtenant has paid all their rent on time.
- Original lease violations: If the sublessor's original lease prohibits subleasing and the sublessor sublets anyway, the landlord may evict the subtenant along with the sublessor.
- Security deposit risk: The subtenant pays a deposit to the sublessor, not the landlord. If the sublessor fails to return the deposit at the end of the sublease, the subtenant must sue the sublessor, not the landlord.
- Fewer legal protections: Some state tenant protection laws apply only to tenants with a direct lease agreement. Subtenants may have fewer statutory rights regarding habitability complaints, notice periods, and rent increases than a primary tenant would.
Section 8 and Subleasing
Tenants holding a Section 8 Housing Choice Voucher are generally prohibited from subleasing their unit.
Section 8 program rules require that the voucher holder actually occupy the unit as their primary residence. Subleasing would mean the voucher holder is not living in the unit, which violates HUD program requirements. A Section 8 tenant who subleases their unit risks losing their housing voucher and may face repayment obligations.
This restriction applies even if the landlord agrees to the sublease. HUD rules supersede the landlord's consent.

When a Landlord Can Refuse a Sublease Request
Even in states that restrict a landlord's ability to withhold consent, landlords generally can refuse a sublease request for legitimate reasons.
- Subtenant fails credit or background check: A landlord can apply the same screening criteria they would use for any prospective tenant. If the proposed subtenant would not qualify as a direct tenant, the landlord can likely refuse.
- Sublease term exceeds the original lease term: The proposed sublease cannot extend beyond the expiration of the original lease's expiration without a lease extension.
- Unit cannot legally accommodate additional occupants: Local occupancy limits (based on square footage and local housing codes) may cap the number of occupants legally permitted in a unit.
- Lease prohibits subleasing entirely: If the lease contains an absolute prohibition on subleasing and applicable state law enforces such clauses, the landlord can refuse any sublease request.
- Proposed use violates lease terms: If the sublease would result in use that violates the original lease (e.g., running a business from a residential unit), the landlord can refuse.
