Co-Tenancy Clause in Commercial Leases: Protecting Retail Tenants When Anchor Stores Leave

April 9, 2026 · 10 min read

When an anchor tenant leaves a shopping center, foot traffic can drop 30 to 60 percent overnight. Without a co-tenancy clause, you keep paying full rent while your sales collapse. With one, you have a contractual right to reduce rent — or walk away entirely. This guide explains how co-tenancy clauses work, how to structure the trigger events, and what to push for before you sign.

What a Co-Tenancy Clause Actually Does

A co-tenancy clause is a lease provision that conditions your rent obligation on the presence of certain other tenants in the property. The logic is straightforward: you chose that location partly because of who else is there. A national anchor — a department store, a grocery chain, a big-box retailer — drives traffic that benefits every surrounding tenant. Your rent was priced on the assumption that traffic would be there.

When the anchor leaves, the economic premise of your lease changes. A co-tenancy clause is how you get the lease to reflect that reality. It gives you either a rent reduction (reduced to a percentage of base rent or a percentage of your gross sales) or a termination right, or both, depending on how long the condition persists.

Co-tenancy clauses are most common in retail leases — shopping centers, strip malls, lifestyle centers, and regional malls. They appear less often in office leases but do show up in medical office buildings and mixed-use properties where one tenant's business depends on another's presence.

Two Types of Co-Tenancy: Anchor and Occupancy

Most co-tenancy clauses fall into one of two categories, and the best leases often include both.

Anchor co-tenancy ties the clause to a specific named tenant. The lease identifies the anchor by name — sometimes by store name, sometimes by entity name — and the clause activates if that tenant vacates, closes, or ceases operations for more than a defined period. The risk: if the landlord replaces the anchor with a different national retailer, the clause may not trigger even if the replacement drives far less traffic.

Occupancy co-tenancy does not depend on any single tenant. Instead, it activates if the gross leasable area of the center drops below a certain occupancy percentage. A clause set at 70% means that if more than 30% of the center sits vacant, your rent adjusts automatically. This is broader protection, but landlords resist it more aggressively because it is harder for them to control.

The Trigger Event: What Counts as "Vacating"

This is where co-tenancy clause disputes most often occur. Landlords draft trigger language narrowly; tenants should push to define it broadly. Consider what each of the following means for your business, and whether your clause covers it:

The most protective trigger language requires the anchor to be "open and continuously operating for retail sales to the general public." That phrase closes the loophole where a dark anchor (paying rent but closed) technically satisfies the lease. Push for "open and operating" language rather than simply "in occupancy."

The Cure Period: How Long Does the Landlord Have to Fix It?

No co-tenancy clause activates the moment an anchor vacates. Every clause includes a cure period — a window during which the landlord can replace the departing tenant before your rights kick in. Cure periods typically range from 90 to 365 days. During this window, you pay full rent even if the anchor space sits dark.

The most common structure is a two-stage timeline:

Negotiate the cure period down as far as the landlord will allow. A 90-day cure period means you start seeing relief much faster than a 365-day cure period. The difference between 90 days and 12 months of full rent during a dead anchor situation can be substantial — on a $15,000/month lease, that gap is $135,000.

How Reduced Rent Is Calculated

The most tenant-favorable co-tenancy rent structure ties your reduced obligation to actual performance, not a fixed number. The standard formulation looks like this:

Why this structure works for tenants:

• If the anchor's departure tanks your sales, you pay 5% of gross sales — which is very low if sales are genuinely down 40–60%.
• The floor (50% of base rent) protects the landlord from paying near-zero rent if your sales happen to hold up despite the anchor leaving.
• It creates aligned incentives: the landlord benefits from replacing the anchor because your rent jumps back to full rate the moment a qualified replacement opens.

Some landlords will push for a simple flat reduction — "50% of Base Rent" with no sales component. That is still meaningful protection but gives you a fixed lower rent regardless of how bad the impact on your business actually is.

The weakest version — one to avoid — caps the rent reduction at a small percentage or limits it to a fixed dollar amount. Language like "Tenant's rent shall be reduced by no more than $2,000 per month" gives you almost nothing on a $15,000/month lease.

The Replacement Anchor: What Counts as "Comparable"?

Most co-tenancy clauses allow the landlord to cure the condition by signing a "comparable" replacement anchor. This word does a lot of work — and how it is defined determines whether the clause provides real protection or just theoretical protection.

A vague clause might say the landlord may cure by "entering into a lease with a replacement anchor tenant." That lets the landlord sign any tenant for the anchor space, even one that drives a fraction of the original traffic, and claim the co-tenancy condition is cured.

A well-drafted clause defines comparable replacement with specifics:

Without a size floor, a landlord can replace a 100,000-square-foot department store with a 20,000-square-foot specialty retailer and claim the co-tenancy condition is cured. Without a national-brand qualifier, a regional or local operator might qualify even if it generates a fraction of the foot traffic.

Also note: "entered into a lease" is weaker than "open and operating." A replacement anchor that has signed a lease but has not yet opened provides no foot traffic benefit. Push for the replacement to be open and operating before the cure is considered complete.

The Termination Right: When Reduced Rent Is Not Enough

Reduced rent keeps you in the space at a lower cost. But if the anchor situation is severe — the center is functionally dead, foot traffic is gone, and there is no realistic prospect of recovery — you may want the option to leave entirely. That is what the termination right provides.

Most co-tenancy termination rights are structured as a second-stage right that activates only after the reduced rent period has continued for some period (often 6 to 12 months). The logic is that rent reduction is the first remedy, and termination is the last resort.

Three things to note about this language:

• The window to exercise is narrow. "Not later than thirty days after" means if you miss the window, the right may lapse. Calendar the date carefully.
• The no-default condition. If you are in default at the time you deliver notice, the right may be void. Cure any open defaults before exercising.
• No termination fee. A co-tenancy termination should not require payment of a termination fee — the landlord's failure to maintain the co-tenancy condition is the cause of the exit. Resist any language that ties a termination fee to the co-tenancy right.

What Landlords Push Back On (and How to Respond)

Landlords dislike co-tenancy clauses because they create contingent obligations that affect the property's value and financing. The most common objections and how to handle them:

Negotiation Checklist

Questions to Ask Before You Sign

• Who are the anchor tenants in this property, and what are the terms and expiration dates of their leases?
• Is there an existing co-tenancy clause in the anchor's lease that I can review?
• Has any anchor tenant given notice of departure or expressed intent not to renew?
• What is the current occupancy percentage of the property, and what is the trend over the past 24 months?
• Does the property have CMBS financing that restricts co-tenancy clauses?
• If my co-tenancy clause is triggered and I reduce rent, will that constitute a default under any other provision of the lease?
• Does my personal guarantee survive if I exercise a co-tenancy termination right?
