Exclusivity Clause in Commercial Leases: How to Stop Your Landlord from Renting to Your Competition

April 9, 2026 · 9 min read

Without an exclusivity clause, your landlord can legally lease the suite next door to your direct competitor. An exclusivity clause prevents that — but only if it is drafted broadly enough to cover your actual business, not just the exact services you offer today. This guide explains how to define your protected category, what your remedies are when landlords violate it, and what to push for before you sign.

What an Exclusivity Clause Does

An exclusivity clause (also called an exclusive use clause or exclusive use provision) restricts the landlord from leasing other space in the same property to a business that competes directly with yours. It is essentially a territorial protection built into the lease.

For a retail tenant, this might mean the landlord cannot lease another suite in the shopping center to another coffee shop, another nail salon, or another optometrist. For a professional services tenant, it might mean no other law firm, dental practice, or financial advisory firm in the building. The specific protection depends entirely on how the clause is written.

Exclusivity clauses are most common in retail leases, food hall leases, medical office buildings, and any multi-tenant property where proximity to a competitor would directly harm your business. They are less common in general office buildings but are achievable for tenants with differentiated uses.

Broad vs. Narrow: The Definition That Determines Everything

The single most important drafting decision in an exclusivity clause is how you define the protected category. Define it too narrowly and a landlord can lease to a competitor while technically complying. Define it too broadly and the landlord will reject it outright.

The key test: would a typical customer of yours consider the competitor's business a substitute? If yes, it should be in your protected category. The clause should protect the customer relationship, not just the brand name.

The Existing Tenant Carve-Out

Every exclusivity clause includes a carve-out for tenants who were already in the property when you signed your lease. This is standard and non-negotiable — you cannot force a landlord to evict an existing tenant on your behalf. What you can and should do is ask, before signing, which tenants are currently in the property and whether any of them operate in your category.

If a competitor is already there, you have two options: accept that the exclusivity clause will not apply to them (and decide whether the location is still worth it), or walk away from the lease. You cannot use exclusivity to solve a pre-existing competitive situation.

The carve-out should be limited to existing tenants and their permitted use at the time of your lease. Watch for language that extends the carve-out to existing tenants' expansions or renewals:

That language lets an existing competitor expand from 2,000 square feet to 8,000 square feet and open a second concept — all without triggering your exclusivity clause. Push to limit the carve-out to the specific premises the existing tenant occupies today, not expansions or new leases for additional space.

How Permitted Use and Exclusivity Interact

These two clauses operate on the same territory, and a weakness in one undermines the other. A narrow permitted use clause limits your own exclusivity protection because exclusivity is often written to reference permitted use language.

The problem: a competitor's permitted use might read "women's lifestyle boutique," "fashion accessories and clothing," or "women's specialty retail" — none of which technically matches "retail sale of women's apparel." The competitor argues they are not in violation. The landlord agrees. You have no practical remedy.

Defining exclusivity by the activity — what the business actually sells — rather than by the permitted use language in some future tenant's lease is far more durable. You cannot control how a landlord drafts another tenant's permitted use clause. You can control how your own exclusivity clause is written.

Remedies When the Landlord Violates the Clause

What happens if your landlord leases to a competitor anyway? Your remedies depend on what the clause says. Most leases offer one or more of the following, in roughly ascending order of tenant-favorability:

The most practical remedy for most tenants is a combination of rent reduction (immediate financial relief) plus a termination right (exit option if the situation does not resolve). Push for both. Landlords will often accept rent reduction but resist a termination right — push back, because a termination right is what gives the clause real teeth.

The Notice Requirement Before Remedies Activate

Most exclusivity clauses require written notice to the landlord before any remedy takes effect. Typically, the landlord gets a cure period — often 30 to 60 days — to remove or modify the competing tenant's use before your rent reduction or termination right activates.

This is reasonable in theory (a landlord might not realize a new tenant's actual operations overlap with yours), but the cure period can be meaningless in practice — if the competing tenant has already signed a lease and opened, the landlord cannot simply evict them in 30 days. Push to make the notice and cure period as short as possible, and make clear that the competing tenant opening for business is itself the triggering event, not just the signing of a lease.

Exclusivity vs. Co-Tenancy: Two Different Protections

Tenants sometimes confuse these two clauses. They protect against different risks and work through different mechanisms.

Many retail leases need both. Exclusivity protects your competitive position when the center is healthy; co-tenancy protects your revenue when the center starts to fail. They are complementary, not redundant.

Exclusivity in Different Lease Contexts

The achievability of exclusivity varies significantly by property type and landlord:

What a Strong Exclusivity Clause Looks Like

Here is a well-drafted exclusivity provision covering the key elements:

Key elements in this language:

• Category definition by activity — "primarily engaged in" the Exclusive Use, not defined by permitted use language
• De minimis carve-out — competitors whose Exclusive Use revenue is below 15% are permitted (avoids blocking restaurants from selling coffee)
• Existing tenant carve-out limited — applies only to current footprint, not expansions or increased use
• Cure period — 30 days before remedy activates
• Dual remedy — rent reduction that activates first, termination right if violation persists
• No termination fee — the landlord's breach is what triggers the exit right

Negotiation Checklist

Questions to Ask Before You Sign

• Who is currently operating in this property, and does any tenant's business overlap with mine?
• Has the landlord granted exclusivity clauses to existing tenants that might limit what I can do?
• Is there a future tenant already committed or in LOI for nearby space who might compete with me?
• How is my protected category defined, and could a competitor reframe their concept to fall outside it?
• What are my remedies if the landlord violates the clause — specifically, is there a termination right?
• Does the exclusivity clause survive a sale of the property to a new landlord?
