Subletting, Assignment And Who Stays Liable

A tenant who arranges for someone else to occupy their unit has done one of two legally distinct things. The distinction decides who the landlord can pursue when something goes wrong.

What a sublease creates

In a sublease the original tenant keeps their lease and grants a lesser interest to someone else. The subtenant's agreement is with the tenant, not with the landlord.

That produces two stacked relationships. The tenant owes rent and performance to the landlord, and the subtenant owes rent and performance to the tenant.

The original tenant is therefore exposed twice over. Unpaid rent or damage caused by the subtenant remains the tenant's problem in the landlord's eyes.

What an assignment does differently

An assignment transfers the tenant's entire remaining interest to another person, who steps into the lease directly. The landlord's counterparty changes.

Even so, the departing tenant is not automatically released. Unless the landlord grants a release, often called a novation, the original tenant can remain contractually liable.

This surprises people who assume signing over a lease ends their involvement. The paperwork that ends liability is separate from the paperwork that transfers occupancy.

Consent clauses and how they operate

Most leases restrict both practices, commonly requiring the landlord's written consent. Some clauses add that consent will not be unreasonably withheld, which narrows the landlord's discretion.

Where consent is required, the request usually resembles a rental application: the proposed occupant is screened as any applicant would be. Refusing on grounds unrelated to that screening can raise legal issues.

Proceeding without required consent is generally a lease breach, which can put the tenancy itself at risk regardless of whether rent keeps arriving.

Short-term letting is a separate question

Listing a unit on a short-stay platform is often treated as subletting under the lease and may also run into building rules, insurance conditions and local ordinances.

Buildings frequently prohibit it outright, and some cities regulate it independently of what the lease says. Compliance with one does not imply compliance with the others.

Because the exposure is layered, the consequences can arrive from several directions at once, including from a homeowner association or a municipal enforcement body.

Where the rules come from

Landlord-tenant statutes govern much of this, and they differ substantially by state and sometimes by city. Some jurisdictions grant tenants rights to sublet that a lease cannot simply remove.

These rules also change over time, particularly around short-term rentals. The current text of the lease and the current local ordinance both need checking rather than assuming continuity.

Where a tenant is trying to leave a lease early, or a landlord is deciding whether to consent, an attorney familiar with local landlord-tenant practice is the right person to ask.
