A restaurant tenant spends real money building out a leased space—a commercial kitchen hood, sinks, the equipment that turns an empty room into a working restaurant. The lease ends earlier than planned. The tenant comes to collect what it paid for. The landlord then says: that belongs to me now. Who is right?
A recent Illinois decision answers the question in a way that should make every commercial tenant—and every landlord—read their alteration clause again. 3 Magpies, Inc. v. Pirrello, 2026 IL App (4th) 250604-U (Feb. 26, 2026).
The tenant leased space in a Rockford commercial building to run a restaurant. To open, it installed a kitchen hood that cost over $10,000, plus sinks and other equipment. The lease’s alteration clause provided that “all such alterations, additions or improvements to the premises by the Lessee [ ] shall become the property of the Lessor upon the expiration of the term of this Lease; provided, however, Lessor shall retain the right to require the Lessee to return the premises to its current condition at the termination of this Lease.” After a fire next door damaged the premises, the landlord terminated the lease and sold the building to a new owner for nominal consideration. When the tenant tried to remove the hood and sinks, the new owner refused, claiming ownership. The tenant sued for unjust enrichment and won $34,000 at trial, on the theory that the equipment was removable “trade fixtures.” The appellate court reversed.
“Termination” and “expiration” meant the same thing
The tenant’s clever argument hinged on a single word. The alteration clause said improvements became the landlord’s property upon “expiration” of the term—but the landlord had ended the lease by “termination” after the fire, before the original term was set to expire. So, the tenant reasoned, ownership had not yet passed when it tried to remove the equipment, because the lease was terminated, not expired. Illinois courts do sometimes distinguish the two words, and the tenant leaned on that distinction hard.
The appellate court rejected it, reading the lease as a whole. Another provision—the tenant’s option to extend—used the phrase “termination date” to mean the end of the original five-year term, which is precisely what the tenant was calling the “expiration date.” If the parties used “termination” to mean the end of the term in one provision, the court reasoned, they did not intend the two words to describe different events elsewhere. The structure of the alteration clause sealed it: the clause said improvements become the landlord’s at the lease’s end, then added, after a semicolon and “provided, however,” that the landlord could require the tenant to restore the premises “at the termination of this Lease.” The two phrases, joined that way, plainly referred to the same moment. Read together, “termination” and “expiration” were synonyms. Ownership of the improvements passed to the landlord when the lease was terminated—so the tenant could not claim the new owner was unjustly enriched by keeping them.
The court added a pointed note: because the lease itself did not distinguish between trade fixtures and ordinary fixtures, the trial court erred by conducting that analysis at all. The lease’s plain language governed, and it gave the improvements to the landlord without regard to how a court might classify them.
Drafting Lessons From a Kitchen Dispute
Say exactly when ownership of improvements passes. If a lease provides that alterations become the landlord’s property, pin the trigger to a defined, dated event and use it consistently throughout the document. Do not write “expiration” in one clause and “termination” in another and assume a court will treat them as different. It may treat them as the same.
Use one vocabulary for the end of the lease. Loose, interchangeable use of “expiration,” “termination,” and “end of term” is a recurring source of disputes. Pick defined terms and use them with discipline. The lease here was undone in part by its own inconsistency.
Spell out removal rights for equipment. A tenant who installs valuable equipment should negotiate, in writing, the right to remove specified items at the end of the lease—and address restoration obligations at the same time. Do not rely on the common-law “trade fixture” doctrine to save you; as this case shows, clear lease language overrides it.
Landlords: a broad alteration clause is a powerful asset. A clean clause stating that all improvements become the landlord’s property at lease-end gave this landlord (and its successor) ownership of a built-out commercial kitchen. If that is the intent, draft it plainly—and consider how it should operate on an early termination, not just a natural expiration.
Think about successors. Ownership of the improvements passed with the building to a new owner who had nothing to do with the original lease. Whatever a lease says about improvements should be drafted to work no matter who holds title when the lease ends.
A buildout is an investment. Whether it walks out the door with the tenant or stays with the building is decided long before the fire—in the lease. Write that clause as though six figures depend on it, because they may.
