What co-tenancy is
A retail tenant does not sign a lease for four walls. It signs for the traffic the rest of the center generates. Co‑tenancy is the clause that makes that bargain enforceable: if the center stops delivering the environment the tenant paid for, the rent changes.
It is the most economically significant clause most inline retailers hold, because rent is their largest fixed cost and co‑tenancy is the only mechanism that makes it move without a renegotiation.
Opening co-tenancy
Opening co‑tenancy governs the start of the lease. It typically allows the tenant to delay opening — and delay paying rent — until the center reaches an agreed occupancy level, or until specified anchors are open and trading.
In a new or repositioned center this produces the standoff the industry knows well: several tenants each waiting on the others before committing to open, with nobody willing to move first. Developers usually break it by granting reduced rent for an opening period rather than letting the space sit dark.
Ongoing co-tenancy
Ongoing — sometimes operating — co‑tenancy runs through the term, and it is where the great majority of unclaimed money sits. It holds the landlord to a standard for the life of the lease: keep the named tenants trading and occupancy above the floor, or the rent changes.
Opening co‑tenancy has an obvious date attached, so somebody is always watching it. Ongoing co‑tenancy has no date. It can trip in any month of a ten-year term, which means it is watched by nobody in particular.
Anatomy of a clause
Nearly every ongoing provision is assembled from the same five parts. Read in that order, a clause that looks impenetrable resolves into something you can test.
- 01
The condition
What must remain true — named tenants open, or occupancy above a percentage, or both.
- 02
The measurement
How occupancy is counted. Almost always by gross leasable area, and very often excluding anchor premises from the denominator.
- 03
The cure
How long the landlord has to fix it, and what counts as a suitable replacement tenant.
- 04
The remedy
What the tenant pays instead — a reduced fixed rent, or a percentage of gross sales.
- 05
The commencement
When the remedy starts. This is the sentence that decides whether detection speed matters, and it usually says: the month after written notice.
If at any time following the Commencement Date (a) fewer than two (2) of the Named Anchor Tenants are open and operating for business, or (b) fewer than four (4) of the Named Inline Tenants are open and operating for business, or (c) less than seventy percent (70%) of the Gross Leasable Area of the Shopping Center, excluding Anchor Premises, is occupied by tenants open and operating for business, then Tenant shall be entitled to pay, in lieu of Minimum Annual Rent, Alternative Rent equal to the lesser of (i) Minimum Annual Rent or (ii) four percent (4%) of Gross Sales, commencing on the first day of the calendar month following the date on which Tenant delivers written notice to Landlord of such condition, and continuing until such condition is cured. Should such condition continue for twelve (12) consecutive months, Tenant may terminate this Lease upon ninety (90) days' prior written notice.
Composed for illustration from common market terms. It is not taken from any executed lease.
Remedies
Three remedies appear repeatedly, and a clause may combine them in sequence — relief first, exit later.
Alternative rent
The tenant pays a substitute rent while the failure continues — commonly the lesser of minimum rent or a percentage of gross sales. This converts a fixed cost into a variable one and is by far the most common remedy.
Abatement
A straight reduction in fixed rent, expressed as a percentage or a stated amount. Simpler to administer, less responsive to how badly trade is actually affected.
Termination
A right to exit, usually only after the condition has persisted for a defined run of months and on notice. Rare to exercise, valuable to hold.
Cure periods
A landlord will normally negotiate a window to replace a departed tenant before any remedy bites. The detail that matters is what qualifies as a replacement: without a definition, a landlord can backfill a former apparel anchor with a use that generates none of the traffic the clause was written to protect.
Well-drafted clauses therefore define a suitable replacement by use, quality and sometimes size. Note also that cure periods frequently differ between tests inside the same clause — a named-tenant failure may be claimable immediately while an occupancy failure carries a grace period.
Why it goes unclaimed
Not through negligence. Through structure. The clause lives in a document; the trigger lives in a building three states away that changes every week. Nothing in a standard lease administration stack connects the two.
“Identification of a co‑tenancy violation is often a difficult undertaking since it is incumbent upon store staff and regional management to note closures and keep the corporate office informed.”
Add the commencement rule — relief running from notice rather than from failure — and the cost of the gap compounds every month it stays open.
Glossary
- Anchor
- A large tenant that drives traffic to the whole center — typically a department store, big-box retailer or grocer. Anchor premises are frequently excluded from the occupancy denominator.
- Named tenant
- A specific retailer identified in the lease whose continued trading the tenant has bargained for. Modern leases name inline brands as often as anchors.
- Gross leasable area (GLA)
- Floor area available to be leased to tenants. The usual basis for measuring occupancy in a co-tenancy test.
- Going dark
- A tenant ceasing to trade from its premises, whether or not it continues to pay rent. A dark unit is normally not “open and operating” for co-tenancy purposes.
- Alternative rent
- Substitute rent payable while a co-tenancy failure continues, commonly the lesser of minimum rent or a percentage of gross sales.
- Natural breakpoint
- The sales level at which percentage rent begins, calculated by dividing minimum rent by the percentage rate. Related machinery, and the origin of this company’s name.
- Occupancy cost
- Total rent as a percentage of a store’s gross sales. The ratio retailers manage to, and the one co-tenancy relief moves.
- Recapture
- A landlord’s right to take back space, often used during repositioning — and a common route to the occupancy decline that trips co-tenancy elsewhere in the center.
Common questions
What is a co-tenancy clause in a retail lease?+
A co-tenancy clause conditions a tenant's rent obligation on the shopping center remaining occupied. If named anchor or inline tenants close, or if occupancy falls below an agreed percentage, the tenant becomes entitled to a negotiated remedy — most commonly reduced or alternative rent, and sometimes a right to terminate.
What is the difference between opening and ongoing co-tenancy?+
Opening co-tenancy applies at the start of the lease: the tenant can delay opening, or open at reduced rent, if the center has not reached an agreed occupancy level by the commencement date. Ongoing (or operating) co-tenancy applies through the term, giving relief if occupancy later falls below the threshold.
What occupancy threshold triggers co-tenancy?+
There is no standard figure — it is negotiated lease by lease. Thresholds are commonly expressed as a percentage of gross leasable area, frequently excluding anchor premises from the denominator. Many clauses combine an occupancy test with a separate requirement that specific named tenants remain open and operating.
What is alternative rent?+
Alternative rent is the substitute rent a tenant pays while a co-tenancy failure continues. It is often expressed as the lesser of minimum rent or a stated percentage of gross sales, which converts a fixed cost into a variable one for as long as the condition lasts.
Does co-tenancy relief apply retroactively?+
Usually not. Many clauses provide that the remedy commences on the first day of the month following written notice from the tenant. Where that is the case, months that pass before the tenant notices and serves notice are generally not recoverable — which is why detection speed matters more than almost anything else.
Can a landlord cure a co-tenancy failure?+
Frequently, yes. Many clauses give the landlord a defined cure period in which to replace the departed tenant, often with a requirement that the replacement be a suitable tenant of comparable use or quality. Only if the cure period runs without a qualifying replacement does the remedy become available.
