Imagine you’re in a location in a property anchored by a major tenant. That tenant draws plenty of visitors, driving up your and all the other tenants’ foot traffic. But one day, the anchor store closes. The foot traffic drops. Your sales slow down.
But your rent? It doesn’t move.
This happens more often than businesses realize, and in most cases, tenants have the contractual right to pay less or even walk away. They just didn’t know it or acted too late.
That right is called a co-tenancy clause. If your lease has one, it could save your business significant money. If it doesn’t or if it’s not being monitored, you’re exposed.
First, Know Your Terms
| Term | What It Means |
| Anchor Tenant | The major tenant that drives foot traffic to the property |
| Minor Tenant/Co-Tenant | Smaller tenants whose business depends on the anchor’s presence |
Some leases also include Key Tenant terms, which function similarly but apply to secondary anchor-level tenants.
Two Types of Co-Tenancy
Opening Co-Tenancy protects you at the start of your lease. If the anchor isn’t open when you move in, you may be entitled to reduced rent or a rent-free period until replaced.
Operating Co-Tenancy protects you during the term of your lease. If an anchor vacates or stops operating, you may have the right to reduce rent or terminate entirely.
Co-tenancy clauses are also structured in one of two ways:
Anchor-Based: Tied to a specific named anchor. If they stop operating, the clause is triggered. Any replacement must be comparable in size, use or category and open and operating, not just leased.
Occupancy-Based: Tied to a minimum percentage of occupied gross leasable area (GLA). Requires continuous monitoring of vacant space and leased vs. open and operating tenants.
The Three Clauses That Matter Most
These are the provisions that carry the most financial weight inside any co-tenancy agreement:
- Rent Reduction Clause: Drops your rent to a lower fixed amount or percentage of sales when a breach occurs
- Rent Adjustment Clause: Keeps rent reduced until a qualified replacement anchor is open and operating
- Termination Clause: Allows you to exit the lease if the breach isn’t cured within a defined period
The Problem Most Businesses Miss
Landlords are not required to notify you when an anchor tenant vacates. No alert. No automatic rent adjustment. Businesses continue paying full rent, sometimes for years, unaware they had the right to pay less.
There is another layer of complexity: lease administrators typically do not have access to the anchor tenant’s lease. This means verifying whether a co-tenancy threshold has truly been crossed requires external market intelligence, direct landlord communication, and careful cross-referencing of occupancy data against your lease language. It requires strong expertise and industry experience, not just document access.
How Co-Tenancy Is Managed the Right Way
| STEP | ACTION |
| Review Lease | Identify co-tenancy clauses, named anchors & occupancy thresholds |
| Obtain Rent Roll | Request current tenant list, square footage & occupancy status |
| Verify Occupancy | Confirm tenants are open & operating, not just leased |
| Calculate Thresholds | Compare occupied SF against lease requirements |
| Assess Violation | Document when the breach began & if cure period expired |
| Determine Remedy | Reduced rent, percentage rent, or termination rights |
| Notify Landlord | Formal written notice citing lease provisions |
| Track & Recover | Monitor ongoing status & recoup any overpayments |
Each step has a deadline and a documentation requirement. Missing one can cost you the right entirely.
