The clause that punishes the thing you were hoping for

The first store works. That was never guaranteed, and for a while it wasn't obvious, but two years in the numbers are steady and the neighborhood knows your name. So you do the natural thing: you start looking at a second location, a few miles away, close enough to share staff and suppliers but far enough to reach a different set of customers.

Then your original lease comes back to bite you. Buried in the middle of it — usually near the percentage-rent language, in a paragraph most tenants skim on the way to the signature page — is a sentence that says you agree not to operate a similar business within a set distance of the leased premises. Sometimes it's a flat prohibition. Sometimes it's worse: the lease doesn't stop you from opening the second store at all. It just quietly counts that store's sales as if they belonged to the first one.

That sentence is a radius restriction clause, and it's one of the few lease terms specifically designed to activate when your business does well.

What a radius restriction actually does

A radius clause (also called a radius restriction or non-compete radius) prohibits the tenant — and usually the tenant's owners, affiliates, and franchisees — from operating a competing or similar business within a defined distance of the leased space for the life of the lease. The distance is measured from the premises outward, and it can be anything from a few blocks in a dense urban corridor to several miles in a suburban trade area.

The landlord's logic is not spite. In most retail and shopping-center leases, the landlord earns percentage rent — a slice of your gross sales above a certain threshold — on top of base rent. That means the landlord is, in a real sense, a silent partner in the store's revenue. If you open a second location a mile away and half your regulars start shopping there instead, the sales at the leased premises drop, and so does the landlord's percentage rent. The radius clause exists to stop you from cannibalizing the very sales the landlord is counting on.

Once you see it as revenue protection rather than a random restriction, the shape of the clause makes sense — and so does the harder version of it.

The two flavors, and why the softer-sounding one bites harder

Radius clauses come in two basic forms.

The first is an outright prohibition: you simply may not operate a similar business inside the radius. Break it and you're in default, exposed to the landlord's remedies — cure demands, damages, potentially termination. It's blunt, but at least it's honest about what it forbids. You know not to open there.

The second form doesn't forbid anything. It's a sales-inclusion or "roll-in" clause, and it reads almost gently: if you open a store within the radius, the gross sales of that new store get added to the gross sales of the leased premises for the purpose of calculating percentage rent. You're free to expand. You just pay the landlord percentage rent on the new store's revenue as though it rang up at the old address.

The second version is the one people miss, because it doesn't sound like a restriction — it sounds like an accounting footnote. But think through what it does. You sign a second lease down the road, with its own base rent, its own percentage rent, its own landlord taking a cut of that store's sales. Then your first landlord reaches over and taxes those same sales a second time. The new location can be profitable on its own books and still bleed money up the street, because one stream of revenue is feeding two percentage-rent meters at once.

The definitions decide everything

Whether a radius clause is a minor footnote or a wall around your growth comes down to a handful of definitions most tenants never negotiate.

The distance. A one-mile radius in a big-city neighborhood might cover a couple of subway stops. A five-mile radius in the suburbs can swallow an entire metro submarket — every plausible site for your second store, gone. The number is not standard and it is not sacred. It's the first thing to push on.

"Similar business." Does the clause cover any store you operate, or only one in the same line of business under the same name? If you run a full-service restaurant at the premises, does a small takeout-only counter count? A ghost kitchen? A stall in a food hall? Loose language here means the landlord decides after the fact what counts as competition.

Who's bound. Well-drafted radius clauses reach past the named tenant to affiliates, parent companies, owners individually, and franchisees. If you personally own a stake in another concept that opens inside the radius, you may have tripped a clause you thought applied only to this one business.

The measurement date and duration. Does the radius apply for the whole term, or only during the early years while the landlord is most exposed? Does it survive renewals? A radius restriction with no sunset follows you for as long as you hold the space.

E-commerce and delivery. This is the modern trap. If "gross sales" is defined broadly and the radius clause folds in nearby locations, a landlord can argue that online orders fulfilled from — or shipped into — the restricted area belong in the percentage-rent calculation. In a world where a lot of retail revenue no longer walks through the front door, an old-fashioned radius clause written for foot traffic can reach places it was never meant to.

What to fix before you sign

Radius clauses are negotiable, and landlords expect the ask. A few concrete moves:

Shrink the radius to the smallest circle that genuinely protects the leased store's trade area — and insist it be measured in a way you can verify, straight-line distance from the premises, not "driving distance" or the landlord's discretion.

Narrow "similar business" to your specific concept, name, and format, so a different offering — a different brand, a different service model, a wholesale operation — falls outside it.

Carve out what already exists. If you already operate other locations, list them by address and exempt them explicitly. You don't want a clause you're in breach of on day one.

Add a sunset. Tie the restriction to the first few years, or let it fall away once the store clears a sales threshold that proves the location is healthy.

Pin down e-commerce. Define gross sales to exclude online and delivery revenue, or at least to exclude it from the radius roll-in, so digital growth doesn't quietly become the landlord's.

None of this requires a fight. It requires reading the clause as what it is — a limit on your future — before the first store succeeds and the limit starts to matter.

Reading the lease your later self will have to live inside

The hard thing about a radius restriction is that it's invisible at signing. On the day you take the space, you have one store and no plans; the clause costs you nothing and asks for nothing. It only wakes up years later, when you're standing in front of the exact opportunity it was written to constrain — and by then the terms are fixed. The lease you skimmed as a formality turns out to have quietly voted on a decision you hadn't made yet.

That's the pattern closeout was built for: reading a commercial lease the way your future self will, surfacing the clauses that stay dormant until the day they cost you — radius restrictions, percentage-rent breakpoints, the definitions that decide how far a single word reaches. It won't sign the lease for you, but it will make sure the sentence about your second store isn't the one you find out about after you've opened it.
