Radius Restriction Clause in a California Retail Lease

A radius restriction clause bars a retail tenant from opening a second location within a set distance — commonly two to five miles — of the store it is leasing, and in Southern California we see it most often in percentage-rent deals for restaurants, fitness concepts, and specialty retail. The landlord's goal is straightforward: keep you from opening a nearby unit that siphons sales away from the center where your rent is partly tied to revenue. Left unnegotiated, a radius restriction clause can quietly cap your growth across an entire submarket for the full term of the lease, so we treat it as a business-plan issue, not boilerplate.

What is a radius restriction clause?

A radius restriction clause is a lease provision that prohibits the tenant, and usually its affiliates and owners, from operating a competing or similar business within a defined radius of the leased premises during the lease term. If the tenant opens inside the prohibited zone anyway, the landlord typically gets a remedy: the right to include the outside store's gross sales in the percentage-rent calculation for the leased premises, injunctive relief to shut the second unit down, or in aggressive drafts a default. The clause is a cousin of the exclusive use clause, but it points the other direction. An exclusive use clause protects you from competitors the landlord might lease to in the same center; a radius restriction restrains you.

The distance is measured as a straight-line radius from the leased premises, and the restricted activity is usually described as a store “of the same or similar name, concept, or type.” Small wording differences carry real weight: whether the clause reaches franchisees, licensees, or a spouse's separate business can decide whether your next lease is even allowed.

Why do landlords ask for a radius restriction?

The radius restriction exists to protect the landlord's percentage rent. When part of your rent is a percentage of gross sales above a breakpoint, the landlord is effectively a minority partner in your revenue at that address. A second store a mile away can cannibalize the first — the same regular customers simply split their visits — which drops reported sales at the leased premises and shrinks the landlord's percentage-rent check. The radius clause is the landlord's hedge against you diluting your own sales inside their center.

That logic is strongest for destination and habit-driven uses: full-service and fast-casual restaurants, coffee, gyms, med-spa and salon concepts, and specialty grocers. It is weakest for uses that draw from a wide trade area or rarely repeat — furniture, a single flagship, or a service with regional draw. We use that distinction at the negotiating table: the more your concept relies on convenience and repeat local traffic, the more a landlord will insist on the radius, and the more precisely we need to draw its edges.

How big is a typical radius restriction in Southern California?

In most Southern California retail leases, a radius restriction runs one to three miles in dense infill markets and three to five miles in lower-density suburban and Inland Empire trade areas. Dense corridors such as those in Los Angeles, coastal Orange County, or Pasadena support a tighter radius because a two-mile circle can already cover several distinct neighborhoods and a large customer base; spread-out markets like Riverside, Corona, or Chino often see a wider radius because trade areas are physically larger.

Context sets the number. A one-mile radius in a walkable stretch of Old Town or along a beach-city Main Street can enclose tens of thousands of residents, so it behaves like a much larger restriction elsewhere. A three-mile radius around a freeway-oriented power center in the Inland Empire may still leave plenty of room to expand. We map the actual circle on a trade-area map before we ever agree to a distance, because two identical-sounding clauses can have wildly different real-world reach.

What does a radius restriction actually cost a growing tenant?

The cost of a radius restriction is measured in lost expansion, not dollars on the rent schedule, and for a multi-unit operator that price can dwarf the rent itself. If your model is to build a cluster of four or five stores across Orange County over a five-year term, a five-mile radius around your anchor location can foreclose the very submarket you planned to saturate. We have seen operators discover, only when scouting a second site, that a clause they skimmed at signing blocks the exact corner they wanted.

There is also a violation cost. If you breach the radius, the standard remedy folds the outside store's gross sales into your percentage-rent math at the leased premises — so you can end up paying percentage rent at one location on revenue you earned at another. In an aggressive lease the landlord may also seek an injunction or declare a default. Those stakes are why we negotiate the scope before signing rather than hoping to fit through a loophole later.

How we negotiate the radius restriction clause down

We work several levers at once. First, the distance: we push a five-mile ask toward two or three miles, and we tie it to a straight-line measurement so it cannot be stretched by driving routes. Second, duration: a radius restriction should not have to survive the entire term, so we negotiate it to burn off after the first two or three years once the store has established its sales base, or to lift once you have paid percentage rent above an agreed floor. Third, the trigger: we narrow the restricted activity to stores operating under the same trade name and concept, so a genuinely different brand you own is not swept in.

We also fix the counting parties — limiting the clause to the named tenant and its controlled affiliates rather than every owner, relative, or passive investor — and we cap the remedy. A landlord may keep the percentage-rent add-back as its exclusive remedy, giving up injunctions and default rights, so that a technical breach never threatens the lease you actually depend on. These points are cheapest to win early, which is why we surface them in the letter of intent before either side is anchored to lease language.

Are radius restrictions enforceable in California?

Radius restrictions are generally enforceable in California as reasonable covenants incidental to a commercial lease, but their outer limits are shaped by the state's strong policy against restraints on business, codified in California Business & Professions Code section 16600. Courts weigh whether the geographic scope and duration are reasonably tailored to protect the landlord's legitimate interest in its percentage rent, rather than simply blocking legitimate competition. You can review the statute directly at the state's official site, California Legislative Information.

The practical takeaway is that an overbroad radius — say, a ten-mile ring for ten years covering every possible brand you might ever own — is far more vulnerable than a tight, term-limited clause tied to your specific concept. We would rather negotiate a defensible clause up front than rely on a courtroom fight after you have already committed capital to a second site.

What should a tenant check before signing?

Before you sign, confirm four things: the distance and how it is measured, how long the restriction lasts, exactly which businesses and people it binds, and what happens if you breach it. Map the radius against your real growth plan across the corridor and the wider county, and make sure a store you already operate does not put you in violation on day one. If any of those answers conflict with where you intend to grow, that is a term to fix now, not a surprise to absorb later.

A radius restriction clause is one line in a long lease, but for an ambitious operator it can shape years of expansion strategy across Orange County, Los Angeles, and the Inland Empire.
