Assignment and Subletting in Commercial Leases

Commercial leases are long, and businesses change faster than lease terms. A tenant that downsizes, sells itself, merges, or simply wants a smaller footprint has two basic ways to hand space to somebody else — assign the lease outright, or sublet part or all of it — and the lease usually restricts both. The clause that governs those moves, often buried past the middle of the document, has more effect on a tenant's flexibility than the rent number on page one.

Commercial landlord–tenant law is state law, and it gives the parties far more freedom than residential law does. The consumer protections that structure residential tenancies mostly do not apply here; what the parties wrote generally controls. Cornell's landlord–tenant overview sets out the general framework, but the operative rules will come from your lease and your state's case law.

Assignment versus sublease

Because the labels carry consequences, courts look at substance rather than what the document is called. A "sublease" that transfers everything through the end of the term is likely an assignment, and a transfer described as an assignment that reserves a right of re-entry may be treated as a sublease in some states. Draft the deal you intend, and check the lease's definitions before naming the document.

The consent standard, and what it does

Most commercial leases prohibit transfer without the landlord's prior written consent. The critical question is which of three standards applies.

1. Absolute discretion. "Consent may be withheld in landlord's sole and absolute discretion." Enforced literally in many states. The tenant's practical remedy is to have negotiated something better at signing.
2. Not to be unreasonably withheld. The common middle ground. Reasonableness is usually measured against objective criteria — the proposed transferee's financial strength, business reputation, proposed use, and fit with the building — rather than the landlord's preference for a higher rent elsewhere.
3. Silent or ambiguous. Where the lease requires consent but says nothing about the standard, states divide. Some read in a duty of reasonableness; others enforce the requirement as an unqualified right. Do not leave this to chance in drafting.

Well-drafted leases go further and list the specific grounds on which consent may be withheld, plus a deadline for the landlord to respond and a stated consequence for silence — deemed consent, or deemed denial. Tenants should insist on both the list and the deadline. A landlord that can simply not answer holds a veto without ever having to justify one.

Tenants should also negotiate carve-outs for permitted transfers that require notice but not consent: transfers to affiliates, parents, or subsidiaries; transfers in connection with a merger or a sale of substantially all assets; and internal reorganizations. Without those, an ordinary corporate transaction can require landlord approval at exactly the moment the tenant has the least leverage — the same dynamic that plays out in commercial agreements generally, discussed in our guide to assignment and change-of-control clauses.

Recapture, profit sharing, and other landlord rights

Consent is rarely the landlord's only tool. Transfer clauses commonly bundle several rights that reshape the economics of any deal the tenant finds.

• Recapture. On receiving a transfer request, the landlord may terminate the lease as to the offered space and take it back, rather than approving the transfer. In a rising market this is the landlord's most valuable right and the tenant's biggest exposure.
• Profit sharing. Rent the tenant receives above its own rent is split with the landlord — 50 percent is a frequently seen figure, though it is entirely negotiable. Tenants should insist that "profit" be net of broker commissions, legal fees, free rent, and the cost of improvements made for the transferee.
• Consent conditions. Payment of the landlord's review costs, delivery of the transferee's financial statements, a signed assumption agreement, and updated insurance certificates.
• Continuing guaranty. Confirmation that any existing guarantor remains bound notwithstanding the transfer — a point every guarantor should read closely, as our article on personal guarantees in business deals explains.
• Use and exclusivity limits. The transferee's use must fit the permitted-use clause, any exclusive granted to another tenant in the center, and local zoning. A change of use can require its own municipal approval under the local zoning code; see our guide to variances, special permits, and land-use appeals.

Recapture and profit sharing are the two provisions most worth trading for at lease signing. A tenant that expects to need flexibility should try to limit recapture to transfers of the whole premises for the balance of the term, exclude permitted affiliate transfers entirely, and require the landlord to elect recapture within a short window so a deal is not left hanging.

Why the original tenant usually stays on the hook

Assigning a lease transfers the estate; it does not by itself erase the tenant's promises. Under ordinary contract principles the original tenant remains liable on its covenants — chiefly rent — unless the landlord grants a release, typically through a novation in which the landlord accepts the assignee in the tenant's place. Landlords rarely give releases without something in return, such as a strong assignee, a security deposit increase, or a payment.

The practical consequence catches sellers of small businesses regularly. Years after the sale, the buyer stops paying, and the landlord sues the original tenant for the balance of a lease it has not occupied since. If a clean exit matters, negotiate the release at the time of the transfer and get it in writing signed by the landlord. Where no release is available, the tenant should at least secure an indemnity from the assignee, a right to notice of any default, and a right to cure before the landlord pursues remedies. What those remedies look like — damages, termination, acceleration where the lease provides for it, and the duty to mitigate, which varies by state — is covered generally in our overview of remedies after a contract breach, and repossession still runs through the court process described in Cornell's summary of eviction.

The transfers tenants do not see coming

Many clauses define assignment to include changes in the tenant entity itself: a transfer of more than a stated percentage of stock or membership interests, a merger, a conversion, a change in managing control, or a series of transfers that cumulatively cross the threshold. A financing round, a founder buyout, or an internal restructuring can therefore trigger a consent requirement without anyone touching the premises.

Two habits prevent the problem. First, read the transfer clause before any corporate transaction closes, not during diligence panic in the final week. Second, if the business is likely to raise capital or be sold, negotiate at signing to exclude transfers to affiliates and transfers in connection with a bona fide financing or sale of substantially all assets, subject only to notice and a financial test the successor can plausibly meet.

Quick answers

The lease says consent will not be unreasonably withheld. What is unreasonable?

Courts generally look at objective, tenant-related factors: creditworthiness, business experience, the proposed use, its compatibility with other tenants, and any added burden on the building. Withholding consent to capture a higher market rent, or to force the tenant to stay, is more likely to be found unreasonable in states that apply an objective test. Ask the landlord to state reasons in writing — the stated reasons frame any later dispute.

Can I sublet part of my space if the lease is silent about subletting?

If the lease genuinely restricts only assignment and says nothing about subletting, the restriction is often read narrowly, since restraints on alienation are typically construed against the drafter. But do not rely on the argument without local advice; many leases define assignment broadly enough to cover subletting, and proceeding without consent risks a default. Ask for written confirmation instead.

What is recapture and why should I care before I have a transferee?

Recapture lets the landlord respond to your transfer request by terminating the lease as to that space and taking it back. If market rents have risen, a landlord may prefer recapture to approving your subtenant, which means the time you spent finding a subtenant produces nothing for you. Negotiate its scope at signing, and understand that submitting a request may be what triggers the right.

Does a landlord's consent to one transfer waive the clause for the next?

Usually not, because most leases say expressly that consent to one transfer is not consent to any other. Where the lease is silent, some states apply a rule that a landlord who consents once waives the restriction as to further transfers. Check the lease language, and if you expect multiple transfers, negotiate for them specifically rather than relying on a waiver argument.

Do residential rules about subletting apply to my commercial space?

No. Residential tenancies carry statutory protections — habitability, deposit rules, notice requirements — that generally do not extend to commercial leases, where courts assume sophisticated parties and enforce the written bargain. If you rent residential property as well, the two sets of obligations should be tracked separately; general consumer housing information is available through USA.gov's housing pages.

A sensible order of operations

At lease signing, negotiate the transfer clause as a business term: define permitted transfers, limit recapture, cap profit sharing net of costs, set a response deadline with a consequence, and pre-agree the criteria for a reasonable transferee. When a transfer becomes live, read the clause first, identify whether the deal is an assignment, a sublease, or a deemed transfer, and assemble the full consent package before you ask. If you need out permanently, put a written release on the table early — it is the one thing you cannot add later.
