It's one of the most valuable protections a retail tenant can negotiate — and one landlords almost never volunteer.
When you lease space in a shopping center, you're not just renting four walls. You're buying into the center's traffic — the customers who come for the grocery anchor, the gym, or the department store and then wander into your shop. A co-tenancy clause is the provision that protects you when that traffic disappears.
How it works
A co-tenancy clause ties your lease obligations to the health of the center around you. It typically triggers in one of two situations: when a named anchor tenant goes dark, or when overall occupancy in the center falls below an agreed threshold — say, 70 or 80 percent. When the trigger hits, the clause gives you a remedy.
The two most common remedies are reduced rent — often a switch to a percentage of your sales instead of full base rent — and, if the situation drags on, the right to terminate the lease entirely. The logic is simple: if you signed up for a busy center and the landlord no longer delivers one, your rent should reflect that.
Why landlords resist it
Co-tenancy shifts risk from the tenant to the landlord, and it can complicate the landlord's own financing. So it's rarely in the first draft of a lease, and when it is, it's usually written narrowly enough to be hard to trigger. That's exactly why representation matters — the clause is only as good as its definitions.
What to watch for
The details decide whether the protection is real. Which specific tenants count as anchors for the trigger? How long does the landlord have to cure before your remedy kicks in? Does replacing a dark anchor with any tenant reset the clock, or does the replacement have to be comparable? A co-tenancy clause that lets the landlord swap a grocery store for a discount furniture outlet and call it cured isn't worth much.
For a smaller inline tenant, co-tenancy can be the difference between riding out a rough patch and going under because the center emptied out around you. It's worth asking for, and worth getting right.
