The ability to assign your lease or sublet space is one of the most valuable — and most restricted — rights in a US commercial lease. Business needs change: you may outgrow your space, downsize, merge with another company, or need to exit a market. Without the right to assign or sublet, you're locked into paying rent on space you no longer need for the full lease term. Landlords have legitimate interests in controlling who occupies their building, but many commercial leases go far beyond reasonable protections — imposing blanket prohibitions, subjective consent standards, recapture rights that allow the landlord to take back the space, and profit-sharing provisions that capture the economic value of your sublease. Negotiating balanced assignment and subletting terms at lease signing is critical.
What is a Assignment and Subletting?
Assignment is the transfer of the tenant's entire interest in the lease to a third party (the assignee), who takes over all rights and obligations. Subletting is the transfer of a portion of the leased premises or a portion of the lease term to a third party (the subtenant), while the original tenant retains their contractual relationship with the landlord. Most commercial leases require the landlord's prior written consent for either transaction, but the standard for that consent varies significantly.
Red flags to watch for
This gives the landlord an unrestricted veto over any transfer, regardless of how qualified the proposed assignee or subtenant is. Many states imply a reasonableness standard, but contractual language can override this.
A recapture clause means that simply asking to assign or sublet triggers the landlord's right to take back the space. This eliminates your ability to explore the market — the moment you tell the landlord you want to sublease, they can cancel your lease.
If you're subletting at a rate above your lease rent (common in rising markets), a 50/50 profit split with the landlord reduces your economic incentive to sublease and captures value that belongs to you.
Landlords routinely charge tenants for their attorney fees to review assignment/sublease documents. Without a cap, these costs can be deliberately inflated to discourage transfers.
Without a 'deemed consent' provision, the landlord can delay indefinitely — neither consenting nor refusing — while your proposed deal dies.
An overly broad restriction on the type of business the assignee can operate effectively prevents assignment in many scenarios, as the most likely buyers of your lease are often in the same industry.
Your legal rights
Assignment and subletting rights in US commercial leases are governed primarily by state common law and the lease terms. Many states (including California, New York, and Illinois) have adopted the rule from Kendall v. Ernest Pestana, Inc. (1985) or equivalent principles implying that landlord consent to assignment cannot be unreasonably withheld, even if the lease grants 'sole discretion.' However, other states allow landlords to withhold consent for any reason if the lease expressly so provides. The Restatement (Second) of Property: Landlord and Tenant § 15.2 supports the reasonableness standard. UCC Article 2A (for personal property leases) allows free transferability unless the lease restricts it. Some jurisdictions distinguish between assignment (which may require reasonableness) and subletting (where courts are less likely to imply a reasonableness standard). State consumer protection statutes generally do not apply to commercial leases.
Questions to ask before you sign
- 1Is the landlord's consent required for assignment and subletting, and what standard applies — 'reasonable' or 'sole discretion'?
- 2Does the lease contain a recapture clause, and if so, does it apply to both assignment and subletting?
- 3Is there a profit-sharing provision for sublet premiums, and what percentage does the landlord take?
- 4Is there a cap on the landlord's legal fees and consent costs for processing a transfer?
- 5Is there a 'deemed consent' provision if the landlord fails to respond within a specified period?
- 6Are there restrictions on the type of business the assignee or subtenant can operate?
