What Percentage Rent and Co-Tenancy Clauses Actually Protect

Retail leases carry two mechanisms that don't really exist in office or industrial: percentage rent and co-tenancy clauses. Both showed up because retail landlords and tenants share something the other asset classes don't, real exposure to how many people actually walk through the door. Understanding what each clause protects, and for whom, is the difference between reading a retail lease and just skimming it.

Percentage Rent Lets the Landlord Share in a Tenant's Upside

In a percentage rent structure, a tenant pays a base rent plus a percentage of gross sales above an agreed threshold, called the breakpoint. The logic is straightforward: if a store dramatically outperforms, the landlord who provided the location and drove the foot traffic gets to participate in that success rather than collecting the same fixed rent regardless of how well the store does. This is common in mall and larger retail formats where the landlord's marketing, anchor tenants, and center management genuinely influence how much traffic a smaller tenant receives. It's far less common in a standalone necessity retail box, where a grocery store's sales have almost nothing to do with what the landlord does beyond keeping the parking lot paved.

The Breakpoint Determines Whether the Clause Actually Matters

A percentage rent clause is only as meaningful as its breakpoint. A natural breakpoint, calculated by dividing annual base rent by the percentage rate, sets the threshold at the point where percentage rent starts making sense mathematically. Some leases negotiate an artificial breakpoint instead, set lower or higher than the natural calculation for negotiating reasons specific to that deal. A buyer evaluating a retail asset's income needs to know not just that percentage rent exists in a lease, but where the breakpoint actually sits, because a breakpoint set unrealistically high means the clause will likely never generate a dollar of additional income no matter how well the tenant performs.

Co-Tenancy Clauses Protect the Smaller Tenant, Not the Landlord

Co-tenancy works in the opposite direction from percentage rent. A co-tenancy clause typically gives a smaller tenant the right to pay reduced rent, or in some cases terminate the lease entirely, if a specified anchor tenant closes or if overall occupancy in the center drops below an agreed threshold. The logic here is that a smaller tenant signed their lease counting on the foot traffic an anchor generates, and if that anchor disappears, the smaller tenant's own sales will likely suffer through no fault of their own. This clause exists because retail tenants are genuinely dependent on their neighbors in a way an office or industrial tenant simply isn't.

Co-Tenancy Risk Is Concentrated in a Specific Kind of Center

The prior piece in this series on necessity versus discretionary retail matters directly here. Grocery-anchored centers rarely trigger co-tenancy problems because grocery anchors don't close at anything like the rate department store and mall anchors have closed over the past decade. A center anchored by a struggling department store chain, or a mall depending on multiple anchors that are each individually vulnerable to the same discretionary spending pressure, carries real co-tenancy exposure that a buyer needs to price into the deal, not just note as a lease term.

Reading These Clauses Tells You Who Actually Bears the Risk

Neither clause is inherently good or bad for an owner. Percentage rent is upside an owner gives up predictability to capture. Co-tenancy is downside protection a tenant negotiates in exchange for accepting a lease in a center with anchor-dependency risk in the first place. What matters in due diligence is reading both clauses for what they actually say, not assuming a retail lease works the way a standard office or industrial lease does just because the base rent and term look familiar.
