Commercial Lease Assignment and Subletting: Tenant Rights and Landlord Approval
February 25, 2026
Assignment vs. Subletting: The Key Difference
Both assignment and subletting involve transferring your lease obligations to someone else — but they work differently:
Assignment: You transfer your entire lease interest to a new tenant. The assignee steps into your shoes completely. You may or may not be released from liability depending on the lease terms and whether the landlord executes a full release.
Subletting: You remain the tenant of record but lease all or part of the space to a subtenant. You're still responsible to the landlord; the subtenant is responsible to you. If the subtenant doesn't pay rent, you still owe the landlord.
Why This Matters: Business Sale, Expansion, Contraction
Business sale: The buyer typically needs the lease transferred. Most business acquisitions require a lease assignment — the buyer won't pay goodwill if they can't keep the location.
Downsizing: You have more space than you need. Subletting the excess recovers some rent cost while you remain in the portion you're using.
Relocation: You want out of the lease. Assignment releases you (ideally with a landlord release) so you can move without paying double rent.
The Landlord Consent Clause
Commercial leases almost universally require landlord consent before assignment or subletting. The key language to look for is the standard of that consent:
- "Landlord may withhold consent in its sole discretion": The landlord can say no for any reason. You have almost no recourse.
- "Landlord shall not unreasonably withhold consent": The landlord must have a legitimate business reason to refuse. Most tenant-friendly leases include this language.
- "Landlord shall not unreasonably withhold, condition, or delay consent": The strongest version — prevents landlord from approving but attaching onerous conditions or dragging out the process indefinitely.
If your lease only says "consent required" without specifying the standard, courts often imply a reasonableness standard — but this creates litigation risk.
What Constitutes Reasonable Denial
When the reasonableness standard applies, landlords can legitimately refuse consent when:
- The proposed assignee has insufficient financial strength to perform under the lease
- The proposed use by the assignee conflicts with exclusive use clauses granted to other tenants
- The proposed assignee has a history of default or business failures
- The assignment would violate a co-tenancy requirement (anchor tenant requirements in retail)
Landlords generally cannot refuse simply because they want to renegotiate the lease at higher rates, or because they have a potential new tenant at better terms.
Recapture Rights
Watch for recapture clauses: if you request consent to assign or sublet, some landlords have the right to "recapture" the space — essentially terminating your lease and dealing with the new tenant directly. This defeats your purpose entirely if you're trying to receive assignment value or sublease income.
Profit-Sharing on Sublease Premiums
If sublease rents exceed your base rent — particularly relevant if market rents have risen since you signed — some leases require you to split that profit with the landlord (often 50/50). This can significantly reduce the economics of subletting in a rising market.
Original Tenant Liability After Assignment
Even after a successful assignment, many leases hold the original tenant secondarily liable if the assignee defaults. This is called "privity of contract" — it survives assignment unless the landlord specifically executes a release. Always push for a full release when assigning, especially if the assignment proceeds from a business sale.
