Co-Tenancy Clauses in NNN Retail Leases: What Landlords Must Negotiate

If you own a strip mall, a power center, or any multi-tenant NNN retail property, co-tenancy clauses are one of the most financially dangerous provisions in your leases — and one of the least discussed.
A co-tenancy clause gives a tenant the right to reduce their rent, defer payment, or terminate the lease outright if a key tenant at the property falls below a specified occupancy threshold. When an anchor goes dark or a center drops below a certain occupancy percentage, tenants with co-tenancy rights can start paying significantly less — or walk away entirely — based on conditions that are completely outside your control.
Here's what co-tenancy clauses look like in practice, why tenants want them, and how to negotiate them so they don't blow up your property's income.

Why Tenants Demand Co-Tenancy Protection
The argument from the tenant side is reasonable on its face: they signed a lease based on the customer traffic generated by the anchor tenant or the overall center. If that anchor closes, their business is materially impacted. They shouldn't be stuck paying full rent in a ghost strip mall.
From a landlord's perspective, that logic leads somewhere you don't want to go. If your anchor leaves and triggers co-tenancy rights across your inline tenants, you can go from a stabilized property to a cascading income collapse — all because one tenant left.
Understanding the structure of these clauses is the first step to negotiating them into something you can live with.

The Two Types of Co-Tenancy Triggers
Co-tenancy clauses typically use one of two trigger types, or a combination of both:
Named anchor co-tenancy: The clause is tied to a specific named tenant — typically the major anchor. Example: "If [Anchor Grocery] ceases operating at the shopping center for more than 180 consecutive days, Tenant may pay Reduced Rent." This type is very specific and somewhat easier to track.
Occupancy-based co-tenancy: The clause triggers if overall occupancy at the center falls below a threshold — say, 80% of gross leasable area occupied and open for business. This is broader and potentially more dangerous because multiple smaller tenants leaving could cumulatively trigger it.
Which is worse for landlords? Occupancy-based co-tenancy triggers are generally harder to manage because they compound. Each tenant that leaves brings you closer to the threshold for everyone else — a domino effect.

What Happens When a Co-Tenancy Clause Triggers
When triggered, a co-tenancy clause typically gives the tenant one or more of the following remedies:
Reduced rent: Rent drops to a specified "co-tenancy rent" — often a percentage of base rent (say, 50%) or a percentage rent only structure. This can cut your effective yield dramatically.
Termination right: After a cure period (typically 6 to 12 months of co-tenancy rent), the tenant has the right to terminate the lease entirely. A termination right is the nuclear option — you lose the tenant and face a vacant space in an already-struggling center.
Rent abatement: Some clauses provide a period of full rent abatement while the landlord works to replace the anchor or bring occupancy back up.
These remedies stack against landlords who are already dealing with the root problem — the lost anchor — while simultaneously trying to manage lender relationships, property taxes, and operating expenses that don't stop.

How to Negotiate Co-Tenancy Clauses as a Landlord
You can't always refuse to grant co-tenancy rights — tenants in strong positions will push hard for them. But you can significantly limit your exposure through negotiation.
1. Push for named anchor co-tenancy only, not occupancy-based
Named anchor provisions are more limited in scope. If a tenant will only accept co-tenancy protection tied to one or two specific anchors, that's far better than a broad occupancy threshold that can be triggered by a series of smaller vacancies.
2. Negotiate a meaningful cure period
The cure period is the window you have to replace the anchor or restore occupancy before reduced rent kicks in. Push for the longest cure period you can get — 12 to 24 months is defensible, especially if you can demonstrate a track record of filling vacancies. A short 60-day cure period on a named anchor is nearly useless; no one replaces an anchor in 60 days.
3. Sunset the co-tenancy right
A sunset provision eliminates the co-tenancy right entirely after a specified period — say, 5 years into the lease term. The rationale: the tenant has been operating and building their customer base; the co-tenancy concern is highest in the early years. After 5 years of successful operation, the argument for co-tenancy protection weakens significantly.
4. Exclude specific causes of anchor vacancy
Negotiate that co-tenancy only triggers if the anchor voluntarily closes, not if it closes due to force majeure, natural disaster, or government-mandated closure. The COVID period showed why this matters.
5. Cap the rental reduction
If you must grant a rent reduction upon trigger, negotiate a floor on what the tenant can pay — don't allow a co-tenancy rent of zero or a purely percentage-rent structure that may pay nothing. A 60–70% rent floor preserves some cash flow and demonstrates continued tenancy commitment.
6. Require the tenant to remain open and operating to access co-tenancy remedies
A tenant who closes their own doors shouldn't be able to invoke co-tenancy rights. Include a provision that co-tenancy protections only apply if the tenant itself is continuously open and operating in the normal course.
7. Eliminate or cap the termination right
A termination right is the provision most worth fighting over. If you can't eliminate it, push to extend the trigger period (tenant must be on co-tenancy rent for 18–24 months before they can terminate), require a termination fee, or limit termination to after the base lease term expires.

Co-Tenancy and Anchor Replacement Strategy
One practical implication of co-tenancy clauses: your speed in replacing an anchor or restoring occupancy is directly tied to your financial exposure. A vacancy that lingers past the cure period starts costing you rent across your inline tenants.
This makes anchor replacement strategy a financial priority, not just a leasing project. When an anchor leaves, your inline tenants are watching the clock. Getting a LOI signed with a replacement tenant — even if they don't open for a year — can stop the co-tenancy clock in some lease formulations if the lease language is right.
When negotiating new anchor leases, push for subletting and assignment rights that give you flexibility to bring in a replacement anchor, co-tenancy cure provisions that treat a signed replacement lease as "cured," and operating covenants on the anchor requiring continuous operation or notice of closure.

The Interaction Between Co-Tenancy and Dark Clauses
Co-tenancy and dark clauses can interact in ways that matter for multi-tenant properties. A tenant with a dark clause (the right to stop operating while still paying rent) can technically "count" as occupying their space for occupancy-based co-tenancy purposes — they're still paying. But if the property has language that requires tenants to be "open and operating," a dark tenant may not count toward the occupancy threshold.
Read every co-tenancy clause against every dark clause in your leases. The interplay can be surprising.

For Strip Mall and Power Center Owners
If you own properties with multiple tenants, co-tenancy exposure across your lease stack is worth auditing before you add new properties. The question isn't just "does my anchor have a solid credit profile" — it's "if the anchor leaves, how many of my inline tenants have co-tenancy rights and what does each of those clauses say?"
Tracking co-tenancy provisions across a portfolio in spreadsheets is doable for small portfolios but starts to break down as you add properties and leases. Being able to pull up the specific co-tenancy provisions across your portfolio when you're negotiating a new anchor deal — or evaluating whether to let an anchor leave — is worth the time to get organized. See our guide on managing multiple NNN properties without spreadsheets for how some landlords approach this.

Co-tenancy clauses aren't automatically deal-killers — sometimes you need to grant them to close a transaction with the right tenant. But going into that negotiation without understanding the full range of exposure, and without a clear negotiating position on cure periods, caps, and termination rights, can leave you with provisions that fundamentally undermine the property's income stability.
