What Is a Co-Tenancy Clause?
The Basic Concept
A co-tenancy clause is a retail lease provision that conditions the tenant's rent obligations — or even their obligation to open — on the presence and continued operation of specific anchor tenants or a minimum level of overall center occupancy. The fundamental premise is that in retail leasing, the tenant is not just renting square footage; they are purchasing access to a customer base that is partly generated by co-tenants. When that customer base shrinks materially because anchor tenants depart, the co-tenancy clause provides contractual relief proportional to the loss.
Co-tenancy clauses are most common in:
- Regional and super-regional malls — where department store anchors historically drove the majority of traffic
- Power centers — where big-box anchors (Walmart, Target, Home Depot, Costco) generate destination traffic
- Community and neighborhood shopping centers — where a grocery anchor drives daily visit frequency
- Lifestyle centers and mixed-use developments — where entertainment or food-hall anchors serve as traffic generators
The clause protects against a fundamental asymmetry: the landlord negotiates leases with all tenants separately and controls the tenant mix, but the small-shop tenant has no direct ability to prevent an anchor from departing, dark-storing, or going bankrupt. The co-tenancy clause shifts some of that anchor departure risk back to the landlord, who is better positioned to control and respond to it.
Opening Co-Tenancy vs. Ongoing Co-Tenancy
Co-tenancy protections come in two distinct forms that operate at different points in the lease lifecycle:
Opening co-tenancy conditions the tenant's obligation to open for business (and begin paying full rent) on the center achieving certain leasing or occupancy metrics at or before the tenant's scheduled opening date. If the developer is building a new center and the tenant committed to the project early — when many leases hadn't yet been signed — the opening co-tenancy ensures the tenant isn't stuck opening a store in a half-empty center with no anchor traffic. Opening co-tenancy thresholds are typically expressed as a percentage of the total center GLA that must be leased to opened-and-operating tenants (commonly 70–80%), or as a requirement that one or more specifically named anchors must be open and operating.
Ongoing co-tenancy applies throughout the lease term after the tenant has opened. It protects the tenant against anchor departures and center degradation that occur during the lease term — events that couldn't be anticipated at lease signing. Ongoing co-tenancy clauses specify: (a) which anchors must remain open (named anchor co-tenancy) or what minimum occupancy percentage must be maintained (occupancy co-tenancy); (b) what relief the tenant receives when the co-tenancy condition fails; and (c) for how long the relief applies before termination rights activate.
| Feature | Opening Co-Tenancy | Ongoing Co-Tenancy |
|---|---|---|
| When it applies | At or before tenant's scheduled opening | Throughout the lease term |
| Primary trigger | Center not X% leased/opened at commencement | Named anchor departs or occupancy drops below threshold |
| Primary remedy | Right to delay opening; reduced rent until satisfied | Rent reduction (typically 50%); percentage-of-sales option; termination right |
| Cure mechanism | Center achieves threshold → full rent resumes | Landlord replaces anchor or raises occupancy → rent restored |
| Termination right | If condition never satisfied within defined period | If co-tenancy failure continues beyond cure period (typically 12–18 months) |
How Named Anchor Co-Tenancy Works
Naming the Anchor
The most powerful form of co-tenancy clause names specific anchor tenants — by tenant name and minimum square footage — whose continued operation is required. A well-drafted named anchor clause might read: "Tenant's obligation to pay Base Rent shall be reduced as specified herein if [Anchor Name] is not open and operating in a space of not less than 80,000 square feet within the Shopping Center for a continuous period exceeding ninety (90) days." The minimum square footage threshold prevents the landlord from claiming co-tenancy compliance when the named anchor has dramatically reduced their footprint or converted to a smaller-format concept.
Naming-based clauses are more protective than occupancy-percentage clauses because they directly identify the traffic-generating tenant whose presence motivated the small-shop tenant's location decision. A tenant who chose a center specifically because of Whole Foods as anchor should name Whole Foods explicitly — not rely on an occupancy percentage that could be satisfied by any replacement tenant, regardless of their traffic-generation capacity.
Occupancy Percentage Co-Tenancy
Occupancy co-tenancy clauses provide relief when the center's overall leased/occupied rate drops below a defined threshold — typically 70–80% of the center's total GLA. This form of co-tenancy is less precise than named anchor protection because it responds to overall center health rather than the departure of a specific traffic driver. A center could remain above the occupancy threshold even after losing its primary anchor if smaller tenants backfill the space, yet the traffic loss from the anchor departure may be severe.
Occupancy co-tenancy is most appropriate in large centers with multiple anchors or in power centers where no single tenant generates majority traffic. In smaller strip centers with a single grocery or drug store anchor, named anchor co-tenancy is almost always the more appropriate protection.
The Financial Stakes: Real Dollar Math
Base rent (full): $40/sf/year = $120,000/yr ($10,000/mo)
Anchor departs — co-tenancy triggered
Co-tenancy reduced rent: $20/sf/year (50% reduction)
Reduced annual rent: $60,000/yr ($5,000/mo)
ANNUAL SAVINGS DURING CO-TENANCY FAILURE:
Full rent: $120,000/yr
Reduced rent: $60,000/yr
Annual savings: $60,000/yr
IF CO-TENANCY FAILURE LASTS 18 MONTHS (TYPICAL CURE PERIOD):
Total rent saved: $90,000
IF TENANT EXERCISES TERMINATION RIGHT AT MONTH 18:
Total rent saved (18 months): $90,000
Avoided future rent (3yr remaining × $120K/yr): $360,000 of obligation
vs. finding new space at market: depends on market
PERCENTAGE-OF-SALES ALTERNATIVE (if negotiated):
Annual gross sales: $900,000
Percentage rent rate: 7% of gross sales
Annual rent at % rate: $63,000
vs. full $40/sf: $120,000
Annual savings vs. full rent: $57,000/yr
Value of well-drafted co-tenancy clause (18-month failure): $90,000+
Sales Impact of Anchor Departure
The financial stakes extend beyond rent savings. When an anchor departs, the small-shop tenant's sales typically drop 15–40% depending on how much of their traffic was anchor-driven. A tenant generating $900,000 in annual sales with a healthy anchor in place may see sales fall to $600,000–$750,000 after anchor departure. The co-tenancy rent reduction partially compensates for this sales decline — but the tenant's real economic exposure is the combined impact of reduced sales and any failure to trigger or enforce the co-tenancy clause.
| Sales Impact Scenario | Pre-Departure Sales | Post-Departure Sales | Sales Drop | Rent as % of Sales (Full Rent) | Rent as % of Sales (Reduced 50%) |
|---|---|---|---|---|---|
| Light anchor dependency | $900,000 | $810,000 (-10%) | $90,000 | 13.3% | 7.4% |
| Moderate anchor dependency | $900,000 | $675,000 (-25%) | $225,000 | 17.8% | 8.9% |
| Heavy anchor dependency | $900,000 | $540,000 (-40%) | $360,000 | 22.2% | 11.1% |
Negotiating Co-Tenancy Clause Terms
Identifying the Right Anchors to Name
The most important decision in co-tenancy negotiation is which tenants to name. Many landlords will offer a "co-tenancy clause" that names anchors who are already on long leases with no realistic near-term departure risk — effectively making the co-tenancy clause a paper right. Tenants should identify the anchors who actually drive meaningful foot traffic to their specific location and insist those tenants be named. Questions to evaluate:
- What percentage of your customer interviews or traffic counts identify the anchor as the reason for visiting the center?
- Which anchors are on shorter leases (5–10 years) that could be up for renewal soon?
- Which anchors are part of retail chains that have been closing stores nationally?
- Which anchor spaces are large enough that departure would create a visible dark storefront affecting center perception?
Structuring the Rent Reduction
Co-tenancy rent reductions are typically structured in one of three ways:
Fixed percentage reduction: The most common structure — base rent is reduced by 25%, 50%, or 75% during the co-tenancy failure period. The reduction amount should be calibrated to the anchor's actual traffic contribution. If the named anchor drives approximately 40–50% of the tenant's traffic, a 50% rent reduction is economically rational.
Percentage-of-sales formula: Rent converts to a percentage of gross sales during the failure period (typically 5–8%). This structure benefits tenants with high sales volume and hurts tenants with low sales volume. Negotiate this option alongside (rather than instead of) a fixed reduction floor.
Reduced rent ceiling: Rent is capped at a defined maximum during the failure period (e.g., $20/sf regardless of the original base rent). This structure is cleanest for lease administration but may not provide proportional relief if the base rent is very high.
The Termination Right: Timeline and Structure
After a co-tenancy failure, most well-drafted clauses give the landlord a cure period (typically 6–18 months) to replace the anchor or restore occupancy. During the cure period, the reduced rent provisions apply. If the cure period expires without cure, the tenant's termination right activates.
Termination right timing structure:
- Notice window: Tenant must deliver written termination notice within a defined window (typically 30–90 days after the cure period expires)
- Termination effective date: Usually 60–90 days after the termination notice, giving both parties time to wind down
- Failure to give notice: If the tenant misses the notice window, the termination right is typically waived for that co-tenancy failure event (though it may be re-triggered if the failure continues)
Key negotiating point: Ensure that the termination right is re-triggered if the landlord cures the co-tenancy failure by bringing in a replacement anchor who then departs within 12 months. A pattern of revolving replacement anchors is not a real cure — it is a series of co-tenancy failures with brief periods of nominal compliance.
Shadow Anchor Provisions
Landlords sometimes negotiate the right to substitute a "shadow anchor" — a large retailer in an adjacent outparcel or pad that is separately owned — for a named anchor when drafting the co-tenancy clause. The theory is that the shadow anchor generates traffic that benefits the center's in-line tenants, so its presence should satisfy the co-tenancy condition even when the named anchor is absent.
Tenants should be skeptical of shadow anchor provisions for several reasons:
- The landlord does not control the shadow anchor's lease terms or continued operation
- The shadow anchor may be on a ground lease that the underlying landowner can terminate
- The shadow anchor's traffic-generation for the main center is indirect and harder to measure
- The landlord could argue that any large retailer visible from the center qualifies as a "shadow anchor," even if it's across a highway
If the landlord insists on a shadow anchor provision, negotiate that: (a) the shadow anchor must be physically contiguous to the center (same parking field, connected walkways); (b) the shadow anchor must be of the same retail category and minimum square footage as the named anchor it replaces; and (c) if the shadow anchor departs, the co-tenancy failure resumes immediately.
Co-Tenancy Clause Comparison Table
| Provision | Weak (Landlord-Friendly) | Acceptable | Tenant-Protective |
|---|---|---|---|
| Anchor identification | Occupancy % only (80%) | Named anchor OR 80% occupancy | Named anchor AND 75% occupancy |
| Failure trigger | Anchor must be closed 180+ days | Anchor closed 90 days | Anchor closed 60 days or announces closure |
| Rent reduction | 25% reduction | 50% reduction | 50% or % of sales, whichever is lower |
| Landlord cure period | 24 months | 18 months | 12 months |
| Termination right | None | After cure period expires | After cure period, exercisable within 90 days |
| Shadow anchor substitution | Any adjacent large retailer qualifies | Same-category, contiguous only | Not permitted / very narrow definition |
| Replacement anchor quality | Any tenant with ≥80% of anchor's sf | Same retail category, same footprint | Must open and operate 90 days before cure deemed effective |
Opening Co-Tenancy: Protecting Yourself Before You Open
What to Negotiate for New Developments
When signing a lease in a new development where anchors haven't yet opened, opening co-tenancy is especially critical. The developer is making projections about who will be co-tenants — projections that may not materialize. Opening co-tenancy provisions should:
- Require that named anchors execute leases (not just letters of intent) before the tenant is obligated to sign their lease
- Define a minimum percentage of GLA that must be open and operating (not just leased) before the tenant's rent commencement date
- Give the tenant the right to terminate the lease and recover their pre-opening costs (design fees, permits, pre-opening inventory) if the opening co-tenancy condition is not satisfied within a defined period (typically 12–18 months after the projected opening date)
Rent Structure During Opening Co-Tenancy Failure
If the tenant is required to open before the co-tenancy condition is met — for example, because the center opens in phases — the opening co-tenancy clause should specify reduced rent (or percentage-of-sales rent) during the period the condition is not satisfied. Tenants should resist landlord pressure to commence paying full rent before the center reaches its leasing/occupancy threshold. A center at 60% occupancy on opening day is a materially different retail environment than what the tenant underwrote when they signed the lease.
6 Red Flags in Co-Tenancy Clause Language
🛑 Red Flag 1: Co-Tenancy Tied to Leased Percentage Rather Than Opened Percentage
A co-tenancy clause that measures center occupancy by the percentage of GLA "leased" rather than "open and operating" is dangerous because a space can be leased but dark (under a signed lease with a tenant who hasn't opened, or who is in a build-out period). Tenants should insist that co-tenancy compliance be measured by tenants who are "open and operating for business to the general public" — not merely parties to a signed lease. Dark stores and build-out spaces do not generate foot traffic for the rest of the center.
🛑 Red Flag 2: No Minimum Square Footage for Replacement Anchors
If the co-tenancy clause doesn't specify a minimum square footage for replacement anchors, the landlord can lease the departed anchor's 100,000 sf space to ten 10,000 sf tenants and argue that the space is "re-tenanted" — even though none of the replacements generates anchor-level traffic. Require that any replacement anchor occupy a space of at least 75–80% of the original anchor's footprint and be of a comparable retail category (a fitness center replacing a department store is not comparable for traffic generation purposes).
🛑 Red Flag 3: Co-Tenancy Clause Carves Out Bankruptcy and Receivership
Some landlords include language that the co-tenancy clause is not triggered if the anchor's closure is due to bankruptcy, receivership, or force majeure. From the small-shop tenant's perspective, the cause of the anchor's departure is irrelevant — the traffic loss is the same whether the anchor went bankrupt, relocated voluntarily, or was forced out. Co-tenancy protection should apply regardless of why the anchor is gone. If the landlord insists on a bankruptcy carve-out, push for a shorter trigger period for bankruptcy closures (30 days rather than 90 days) to compensate.
🛑 Red Flag 4: Termination Right Requires Exercise Within Very Short Window
Some co-tenancy clauses impose a 30-day window to exercise the termination right after the cure period expires. This is problematic because: (a) a tenant may not notice exactly when the cure period expires; (b) the tenant may need more than 30 days to evaluate whether a new replacement anchor changes the calculus; and (c) tenants are often focused on operations rather than tracking lease deadlines with precision. A 60–90 day termination notice window is more reasonable and allows the tenant to make a thoughtful decision about whether termination is the right response.
🛑 Red Flag 5: Landlord Can Cure by Designating Any Space as "Anchor"
Watch for co-tenancy clauses that give the landlord sole discretion to designate a replacement "anchor tenant" without requiring the replacement to be of a comparable retail category or traffic-generation capacity. A landlord could argue that a 90,000 sf self-storage facility "replaces" a department store anchor — the replacement occupies the space, but it generates no meaningful pedestrian traffic. Require that replacement anchors be retail or restaurant tenants open to the public with regular operating hours, operating in a comparable merchandise category.
🛑 Red Flag 6: Percentage-of-Sales Formula Has No Floor
When the co-tenancy clause converts rent to a percentage-of-sales formula during a failure period, ensure there is a minimum rent floor below which the percentage calculation cannot go. Without a floor, if the tenant's sales collapse completely (which can happen during severe anchor departures), the tenant could theoretically pay near-zero rent — which might sound good, but creates ambiguity about whether the landlord can treat near-zero rent as a de facto default. A minimum floor of 30–40% of the original base rent prevents this ambiguity while still providing meaningful relief.
✅ 12-Item Co-Tenancy Clause Negotiation Checklist
- Name specific anchor tenants by name and minimum square footage — not just an occupancy percentage. The named anchors should be the tenants whose presence actually motivated your location decision.
- Define "open and operating" carefully — the anchor must be conducting regular retail operations open to the public, not merely a party to a signed lease or in a temporary closure for renovation.
- Set an opening co-tenancy threshold of 70–80% of GLA open and operating — not just leased — before your rent commencement date if signing in a new or redeveloping center.
- Require rent reduction of at least 50% (or percentage-of-sales alternative) during any ongoing co-tenancy failure — calibrated to the anchor's actual traffic contribution to your sales.
- Cap the landlord's cure period at 12–18 months — longer cure periods expose you to years of reduced-but-not-zero rent in a degraded center without any exit mechanism.
- Define "cure" as the replacement anchor being open and operating for 90 days — not merely signing a lease or commencing construction. Paper replacements don't drive foot traffic.
- Require replacement anchors to be of a comparable retail category and minimum 75% of original anchor's square footage — a dollar store in a former department store does not constitute cure.
- Negotiate a termination right exercisable within 60–90 days after the cure period expires — with a clean termination effective date of 60–90 days post-notice.
- Restrict shadow anchor substitution or impose strict requirements — the shadow anchor must be physically contiguous, same category, same minimum size, and subject to re-triggering if they depart.
- Ensure the co-tenancy clause applies regardless of the reason for anchor departure — bankruptcy, voluntary relocation, lease expiration, and force majeure should all trigger the clause.
- Apply co-tenancy protection to renewal terms — confirm that the co-tenancy clause survives lease renewal and is not extinguished or modified upon option exercise.
- Track co-tenancy compliance proactively — calendar the anchor's lease expiration dates, monitor center occupancy changes, and confirm you are receiving required landlord notices about anchor departures.
