Co-Tenancy Clauses in Shopping Centers: The Quiet Vacancy Trigger

TL;DR

A co-tenancy clause is a provision in a multi-tenant retail lease that ties one tenant's obligations to the continued occupancy of other tenants in the center. The most common version: "if Anchor Tenant X (or a substitute meeting Y criteria) vacates, Tenant has the right to (a) abate rent, (b) reduce rent to percentage rent only, or (c) terminate the lease." With anchor tenants closing stores in waves over the past several years, co-tenancy clauses have shifted from a theoretical risk to an active underwriting concern. Most OMs marketing multi-tenant retail centers don't disclose co-tenancy terms in detail — and the vacancy of a single anchor can cascade into 30-50% NOI reductions.

What a Co-Tenancy Clause Looks Like

A typical co-tenancy clause has three components:

1. The Triggering Event

The clause defines what counts as "vacancy" of the protected co-tenants. Common formulations:

• Named anchor: "If Walmart, Walgreens, or a successor of similar quality vacates the Shopping Center..."
• Anchor by category: "If the [grocery anchor / drug anchor / department store anchor] tenant ceases operations..."
• Occupancy threshold: "If the Shopping Center occupancy drops below 70% of leasable square feet..."
• Combination: "If Walmart vacates AND occupancy drops below 80%..."

The triggering event is usually defined as continuous closure for X days (typically 90-180 days), not a single day of closure. This gives the landlord a window to backfill before the co-tenancy remedy kicks in.

2. The Tenant Remedy

If the trigger fires, the tenant typically has one or more of these remedies:

• Rent abatement: tenant pays 0% or 25-50% of base rent for as long as the co-tenancy failure continues
• Percentage rent only: tenant pays only percentage rent (typically 4-8% of gross sales) instead of base rent — meaningful reduction if sales are also declining
• Right to terminate: tenant can terminate the lease with 30-90 days' notice, often after a defined cure period (e.g., 12 months for landlord to backfill the anchor)
• Combination: rent abatement initially, with right to terminate if the failure continues for X months

3. The Landlord Cure Right

Many co-tenancy clauses give the landlord a window to "cure" the co-tenancy failure by backfilling the anchor space with a comparable tenant.

• Time window: typically 9-18 months after the anchor closes
• Replacement tenant criteria: usually defined as "similar quality" or "of comparable size and use" — varies by lease

If the landlord backfills within the window, the co-tenancy clause goes back to dormant. If not, the tenant remedies become permanent (or convert from rent abatement to right to terminate).

Why This Has Become a Material Underwriting Issue

For decades, anchor tenants in regional shopping centers were stable: Sears, JCPenney, Macy's, Walmart, Target, large grocery chains. The co-tenancy clause was a theoretical protection that rarely got triggered.

Over the past several years, this has changed:

• Sears / Kmart bankruptcies and closures triggered co-tenancy clauses across hundreds of shopping centers
• JCPenney's Chapter 11 reorganization and store closures triggered more
• Bed Bath & Beyond's bankruptcy affected centers anchored by it
• Walgreens' announced 1,200+ store closures (October 2024 announcement, ongoing through FY2027) is a current and unfolding trigger
• CVS's HealthHUB transformation and the related ~900 store closures (2022-2024) similarly

When an anchor closes in a center where multiple in-line tenants have co-tenancy clauses, the landlord can lose 25-60% of the center's NOI even though only one tenant has actually vacated. The remaining tenants' rent abatements compound the impact.

How Most OMs Disclose Co-Tenancy (or Don't)

In our review of net lease OMs, the typical disclosure is:

• No mention in the executive summary or rent roll
• A footnote in the tenant schedule: "subject to co-tenancy provisions"
• Buried in the lease abstract appendix with terms that take careful reading to understand
• Sometimes a list of "in-place anchor tenants" that gives no indication which are co-tenancy triggers

For a buyer, the underwriting workflow has to include reading every in-line tenant's lease for co-tenancy provisions, mapping which ones tie to which anchor, and quantifying the cascade if any single anchor leaves.

Three Things to Look For in Each Lease

1. Specifically Named Co-Tenants vs Categorical Co-Tenants

A lease that names "Walmart" specifically is materially different from a lease that names "any nationally-recognized supermarket anchor." The categorical version gives the landlord more flexibility to backfill (any supermarket counts). The specific version is binary — Walmart or termination.

For shopping centers anchored by tenants in contracting industries (drug, department store, certain grocery), specific-named co-tenancies are higher risk because the landlord may not be able to find a like-for-like replacement.

2. Cure Periods and Cure Standards

A 6-month cure period is much harder for the landlord to meet than an 18-month one. Anchor space backfills are slow — site selection, lease negotiation, build-out, and opening typically take 12-24 months even for healthy retailers.

Pay attention to the cure standard: "comparable in size and use" is more flexible than "of comparable national-chain status and quality."

3. Cumulative vs Stand-Alone Triggers

Some leases have cumulative co-tenancy provisions: not just one anchor closing, but center-wide occupancy below a threshold. These can be quietly devastating because they create a vacancy cascade — one tenant vacating triggers another's co-tenancy, which triggers a third's, and so on.

Specifically watch for clauses that reference both an anchor closure AND an occupancy threshold ("70% occupancy" being common). With anchor square footage often 30-50% of total GLA, an anchor leaving can immediately drop the occupancy ratio below the threshold.

Modeling Co-Tenancy in the Underwriting

A defensive underwriting framework for a multi-tenant retail center with co-tenancy exposure:

Step 1: Map the Triggers

For each in-line tenant, identify:

• Which anchor's closure triggers the co-tenancy
• What the remedy is (abatement, percentage rent, termination)
• What the cure period is
• Whether there are cumulative triggers

Build a simple matrix: rows = anchors, columns = in-line tenants, cells = triggered remedy if anchor vacates.

Step 2: Run a Scenario for Each Anchor

For each anchor in the center, model:

• The lost rent from the anchor's vacancy
• The compounded rent abatements from in-line tenants whose co-tenancy triggers
• The probability of landlord cure within the cure period (function of submarket demand, anchor space size, and replacement tenant universe)
• The terminal value if the cure fails (portion of in-line tenants exercise termination)

Step 3: Apply Probabilities

For each anchor, estimate the probability of vacancy over the underwriting horizon:

• Strong national tenant on long lease, growing footprint: 5-10%
• Stable national tenant, mature business: 10-20%
• National tenant in contracting industry: 25-50%
• Declining tenant on a near-term expiration: 50-75%

Multiply each scenario's NOI impact by its probability to arrive at a probability-weighted NOI vs the headline pro-forma NOI.

Step 4: Adjust the Cap Rate

The probability-weighted NOI gives you a more honest year-1 number. The cap rate should also reflect the systemic vacancy risk — a center with three at-risk anchors and a co-tenancy cascade should price 100-150 bps wider than a center with the same headline NOI but no co-tenancy exposure.

A Worked Example

Consider a 100,000 sq ft shopping center:

• Walmart (40,000 sq ft anchor): $8/sf NNN = $320,000 base rent
• Five in-line tenants (60,000 sq ft total): blended $24/sf NNN = $1,440,000 base rent
• Total NOI: $1,760,000
• Asking cap rate: 7.0%
• Implied value: $25.1M

Co-tenancy disclosure (read in the in-line leases):

• 4 of 5 in-line tenants have co-tenancy clauses tied to Walmart's continued operation
• Remedies: 50% rent abatement after 90 days of anchor closure; right to terminate after 18 months of continuing failure

Stress scenario: Walmart vacates. Cure period of 12 months in their lease (so the rent loss starts immediately on their side). For the in-line tenants:

• 4 of 5 abate 50% of rent immediately ($1,440,000 × 4/5 × 0.5 = $576,000 lost)
• Walmart rent of $320,000 is also lost
• Total NOI in vacancy scenario: $1,760,000 - $576,000 - $320,000 = $864,000 — a 51% NOI reduction from a single tenant departing

If the landlord can't backfill within the 18-month cure window, the 4 in-line tenants can exercise their termination rights, and the center NOI craters further. The landlord faces a redevelopment scenario with most of the rent gone.

Underwriting takeaway: even before considering Walmart's actual likelihood of vacating, the buyer should price this asset with a meaningful co-tenancy risk premium. A 7.0% headline cap rate that doesn't reflect this exposure is structurally underpriced.

What's Hard to Get From an OM

The OM will usually tell you:

• Anchor tenant names
• Anchor square footage
• Aggregate occupancy

The OM usually won't tell you:

• Which in-line tenants have co-tenancy clauses
• What the triggering events are
• What the remedies are
• What the cure periods are
• Whether the leases have cumulative occupancy triggers

You have to read the leases yourself — usually in the data room appendix. For shopping center deals over $5M, this is non-negotiable diligence.

Practical Workflow

1. Pull every in-line tenant's lease during the LOI / contract diligence period
2. Build the co-tenancy matrix as described above
3. Identify the highest-risk anchor based on tenant credit + industry trajectory
4. Run the cascade scenario and quantify the NOI impact
5. Adjust the cap rate in your offer or re-trade demand based on the exposure
6. In the IC memo, include a one-paragraph co-tenancy summary so the IC understands the structural risk

For sellers and listing brokers, the discipline is to build the co-tenancy matrix during pre-marketing and disclose it transparently in the OM. Surprises in escrow re-trade or kill deals; transparency upfront converts the issue into a properly-priced data point.

Co-tenancy clauses are no longer a theoretical risk in 2026 multi-tenant retail underwriting. They're a primary structural risk worth as much underwriting attention as tenant credit.
