Assigning vs Subletting a Commercial Lease in Texas
A Houston tenant's and owner's guide to transferring space you no longer need, the right way
Businesses outgrow space, consolidate, or relocate long before a commercial lease runs out. When that happens in Texas you usually have two exits, assigning the lease or subletting the space, and they are not the same decision. This guide explains how each one works in a Houston commercial lease, what landlord consent really requires, who stays on the hook for the rent, and how to protect yourself before you sign a transfer.

Assignment vs Sublease: What Actually Changes
An assignment transfers your entire remaining lease to a new tenant, who steps into your shoes for the rest of the term. A sublease keeps you on the original lease and creates a second, smaller lease between you and a subtenant. The difference drives everything that follows, from liability to landlord approval, so it is worth settling before you market the space. If you are still learning how your lease is structured, start with our overview of how to read a Houston commercial lease and the plain-English breakdown of commercial lease types.
Under an assignment, the assignee takes on the full obligations of the lease, including rent, operating costs, and any triple net (NNN) charges the lease passes through. Unless the landlord signs a written release, though, the original tenant often remains secondarily liable if the assignee defaults. That single point, release of liability, is the most overlooked term in a Texas assignment, and it is the first thing a broker should negotiate for you.
A sublease is useful when you only need to offload part of your space, or when you expect to return, because you keep control of the master lease. The trade-off is that you become a landlord yourself. You collect rent from the subtenant, you remain fully responsible to the building owner, and you absorb the risk if the subtenant stops paying. Most Houston leases require the owner’s written consent for either path, and many add a recapture right that lets the landlord take the space back instead of approving your transfer.
Assignment vs Sublease, Side by Side
How to Assign or Sublease Your Houston Space
Read your transfer clause first
Find the assignment and subletting section of your lease. It tells you whether you need consent, whether the landlord can recapture the space, and whether any profit on the transfer is shared. Everything else depends on this language.
Decide assign or sublease
If you are leaving for good and want off the hook, aim for an assignment with a written release. If you are offloading part of the space or may return, a sublease keeps your options open.
Price the space to today's market
A broker runs current comparables for your submarket so you are not carrying empty space for months or giving it away below market. Lake Houston, Kingwood, and Humble rents move independently of downtown.
Request landlord consent in writing
Send the owner the proposed tenant's financials and the business terms. Track the response deadline your lease sets, and push back if consent is delayed past it.
Paper the deal properly
Use an assignment-and-assumption agreement or a written sublease, not a handshake. Attach the master lease, address the security deposit, and state who carries insurance and pays operating costs.
Lock in a release of liability
On an assignment, negotiate a landlord release so you are not chasing an assignee's unpaid rent two years later. This is the single most valuable term for a departing tenant.
Confirm the handoff
Document the condition of the space, transfer utilities and signage rights, and get estoppel confirmation that the master lease is in good standing before you walk away.
The Lease Clauses That Control Your Options
Texas gives landlords wide latitude here. If your lease simply says consent is required, a court will usually enforce whatever the lease says, including an absolute right to refuse, because Texas does not imply a reasonableness standard the way some states do. The protection has to be written in. Good tenant-side language says consent will not be unreasonably withheld, conditioned, or delayed, sets a response deadline, and spells out what the landlord may and may not consider. When a transfer is on the table, the landlord will also want current financials and often a signed estoppel certificate and, where a lender is involved, an SNDA from the new party.
Before You Sign, and the Other Side of Your Move
Before you ever sign a transfer, get the deal framed in writing. A short letter of intent that names the rent, term, condition of the space, and who pays for improvements keeps an assignment or sublease from falling apart over a misunderstanding. If you are exiting because the business is expanding or relocating, you are also about to be on the other side of a transaction, leasing or buying new space, and sometimes selling an owned building. That is where working with a Houston commercial real estate broker on both the exit and the next space saves the most money. Owners weighing a sale instead of a transfer should start with a realistic commercial property valuation or a broker opinion of value.

Talk to a Commercial BrokerFrequently Asked Questions
Is subletting the same as assigning a lease in Texas?
No. An assignment transfers your whole lease to a new tenant who takes over the remaining term, while a sublease keeps you on the original lease and creates a second lease between you and a subtenant. With a sublease you stay responsible to the landlord; with an assignment you are responsible only until the landlord releases you in writing.
Can my landlord refuse to let me assign or sublet?
Often, yes. Texas enforces the lease as written, so if your lease gives the landlord an absolute right to withhold consent, a court will usually uphold it. The protection comes from negotiating language that says consent will not be unreasonably withheld, conditioned, or delayed, ideally with a deadline for the landlord to respond.
Am I still liable for the rent after I assign my lease?
Usually, unless you get a written release. Most assignments leave the original tenant secondarily liable if the new tenant defaults. Negotiating a landlord release of liability as part of the assignment is the single most important step for a tenant who wants a clean exit.
What is a recapture clause?
It is a landlord’s right to take the space back and cancel that portion of your lease instead of approving your proposed assignment or sublease. If your lease has one, the landlord can effectively block your transfer, so you need to know it is there before you market the space.
Do I need landlord consent to sublease a few offices?
Almost always. Even a partial sublease of a suite typically requires the owner’s written consent under a Houston commercial lease, and the owner can usually review the subtenant’s financials and intended use first. Read your transfer clause and request consent in writing before you commit to a subtenant.
Should I use a broker to assign or sublease my space?
It helps in two ways. A broker prices the space to the current submarket so you are not carrying it empty, and handles the consent, documents, and release negotiation so the transfer holds up. If you are exiting to expand or relocate, the same broker can line up your next lease or purchase at the same time.
