Subletting a Rental
Subletting — also called subleasing — occurs when a tenant rents their unit (or a portion of it) to another person, known as a subtenant, while still remaining a party to the original lease. The original tenant acts as a middleman landlord: they collect rent from the subtenant and remain responsible to the property owner. The arrangement is typically temporary, covering a defined period when the original tenant cannot occupy the unit.
Subletting differs from a lease assignment, in which the original tenant transfers all lease rights and obligations to a new party entirely. In a sublet, the original tenant retains legal liability throughout the sublease term.

Why Tenants Consider Subletting

Life rarely conforms to a fixed lease term. A job relocation, a temporary move to care for a family member, an extended travel opportunity — these situations leave renters with an active lease and an empty apartment. Subletting offers a practical solution: keep the lease intact, avoid breaking it early, and offset costs by bringing in a subtenant for the interim period.

That logic is sound, but the execution carries real risk. Many tenants assume subletting is straightforward or that their landlord won't notice. Both assumptions frequently lead to serious consequences. Before exploring how to sublet, it's worth understanding exactly what you're taking on. See also what renters get wrong about breaking a lease early — subletting and early termination are sometimes confused, but they carry very different outcomes.

Your Lease Is the Starting Point

Before contacting a potential subtenant, locate the subletting clause in your lease. Lease language on this topic falls into three broad categories:

  • Outright prohibition: The lease forbids subletting entirely. Proceeding without permission is a lease violation and grounds for eviction.
  • Permission required: Subletting is allowed but only with written landlord consent. This is the most common arrangement, and it usually requires you to submit a formal request and identify the proposed subtenant.
  • Permitted without restriction: Less common, but some leases allow subletting without advance approval.

Even where your lease is silent on the topic, state law governs the default rules. Some jurisdictions give tenants a statutory right to sublet; others leave it entirely to the lease. Reviewing tenant rights every renter in America should know can help you understand the broader legal framework that applies in your state.

Always Get Landlord Approval in Writing

Even if your landlord verbally agrees to the sublease, get confirmation in writing before the subtenant moves in. A written record protects you if the landlord later claims they never approved the arrangement. Email confirmation is generally sufficient, but a signed letter is stronger.

The Liability Problem Most Tenants Underestimate

The most misunderstood aspect of subletting is this: the original tenant never escapes their obligations under the lease. You are the landlord's counterparty. If your subtenant pays rent late, skips payments entirely, damages the property, or violates lease terms, the landlord's legal recourse is against you — not the subtenant.

This dynamic also applies to the security deposit. The landlord holds your deposit and evaluates it based on the unit's condition when your lease ends — regardless of who caused the damage. Many tenants collect a separate deposit from their subtenant precisely to protect against this exposure, but that arrangement exists only between you and the subtenant; your landlord is not party to it.

U.S. states with varying subletting laws

Every state sets its own statutory framework governing tenant subletting rights, making local legal verification essential before any sublease arrangement.

Understanding the distinction between subletting and a full lease transfer matters here. Subletting, assignment, and lease transfers each carry different liability profiles — and confusing them can leave you legally exposed in ways you didn't anticipate.

Getting Permission and Putting It in Writing

If your lease requires landlord consent, submit a written request that identifies the proposed subtenant, the sublease start and end dates, and your reason for subletting. Keep a copy of every communication. Some states require landlords to respond within a set number of days; an unreasonable refusal may not be enforceable in those jurisdictions.

Once you have permission, document the sublease itself in a written agreement with your subtenant. That document should cover rent amount and payment schedule, utility responsibilities, rules about guests and alterations, and conditions for early termination. Verbal agreements are difficult to enforce and leave both parties exposed.

Vet your subtenant carefully. Running a credit and background check — with the applicant's written consent — is standard practice and prudent risk management. You are, in effect, selecting someone who will live in your home and represent your tenancy in your absence.

Frequently Asked Questions

In most states, a landlord can lawfully prohibit subletting if the lease explicitly bans it. Some states and cities — including New York — give tenants the right to sublet even over a landlord's objection under certain conditions. Always check your lease and applicable local law before proceeding.

Yes. As the original tenant, you remain fully liable for the rent under your lease regardless of whether your subtenant pays you. If the subtenant defaults, the landlord can pursue you for any unpaid amounts.

The landlord typically holds your original security deposit and will return or deduct from it based on the unit's condition at the end of your lease. Any damage caused by a subtenant is still your financial responsibility with the landlord.

Whether you can charge a subtenant above your own rent depends on state and local law. In rent-stabilized or rent-controlled markets, overcharging a subtenant may be illegal and can expose you to penalties.

A sublease should specify the rental period, monthly rent amount and due date, security deposit terms, rules about guests and utilities, and each party's responsibilities for property care. Both parties should sign and retain a copy.

In a sublet, the original tenant stays on the lease and retains liability. In an assignment, the tenant transfers all lease rights to a new tenant, removing themselves from the arrangement — though this usually requires landlord consent.
