A Non-Disturbance Clause (NDC) is a provision often found in commercial leases or mortgage agreements that protects a tenant’s right to remain in a property even if the property changes ownership or the landlord defaults on their mortgage. The clause ensures that the tenant's occupancy will not be disturbed by a new property owner or lender, as long as the tenant is complying with the lease terms.
Non-disturbance clauses are most commonly used in triple-net leases (NNN), where tenants lease commercial real estate and agree to pay for taxes, insurance, and maintenance. The clause provides tenants with a safeguard, ensuring they can continue to operate their business without disruption in the event of a foreclosure or change in ownership.
How Does a Non-Disturbance Clause Work?
The Non-Disturbance Clause is usually included in the lease agreement between the tenant and the landlord or as part of an agreement between the landlord and the lender. It’s typically paired with a Subordination Clause and an Attornment Clause:
Subordination Clause – This clause allows the landlord’s interest to be subordinate to the lender’s claim, meaning that if the landlord defaults on their mortgage, the lender has first claim over the property.
Attornment Clause – This clause obligates the tenant to recognize and accept a new owner if the property is sold or foreclosed upon.
In a typical lease, if the landlord defaults on their mortgage, the tenant’s lease can be terminated by the lender, resulting in the tenant being evicted. However, the non-disturbance clause ensures that even if the landlord defaults or the property changes ownership, the tenant can stay in the property as long as they honor the lease agreement.
Importance of a Non-Disturbance Clause
The Non-Disturbance Clause (NDC) offers several key protections for tenants. First, it provides stability and security by ensuring that tenants can remain in the property even in the event of a change in ownership or foreclosure. Without an NDC, tenants might face the risk of losing their leasehold rights if the property is sold or repossessed. It also fosters tenant confidence, as knowing that operations can continue uninterrupted under new ownership allows tenants to commit to long-term leases. This is especially critical for businesses that have made significant investments in property improvements or customized spaces. Additionally, the NDC offers protection against foreclosure by guaranteeing that the tenant's right to occupy the space remains intact as long as they are in compliance with the lease terms. Finally, the inclusion of an NDC can give tenants enhanced negotiation leverage during lease discussions, especially in high-demand spaces or for long-term tenants, providing a valuable bargaining chip to secure favorable lease terms.
How to Secure a Non-Disturbance Clause
Tenants should take the following steps to secure a Non-Disturbance Clause:
Include It in the Lease Agreement – Tenants should ensure that the clause is clearly included in their lease, typically as part of the negotiation process for commercial leases.
Negotiate With the Lender – Often, landlords must agree to the clause in conjunction with the lender, so tenants may need to work with the landlord and their lender to ensure the clause is enforceable.
Request Confirmation – In cases where a property is subject to a mortgage, tenants should request that the lender acknowledge and sign off on the Non-Disturbance Clause to ensure enforceability.
Risks and Limitations
While a Non-Disturbance Clause offers protection, it’s not without its risks and limitations:
Involvement of Lenders: If a lender is unwilling to sign or acknowledge the clause, tenants may be exposed to the risk of eviction in the event of foreclosure.
Lease Violation by Tenant: If a tenant violates the lease terms, they could lose the protection of the NDC, even if the property changes hands.
Limited Scope: The clause protects tenants from disruptions due to changes in ownership or foreclosure, but it may not protect tenants in other scenarios, such as if the landlord needs to make property alterations or if the tenant cannot pay rent.
Final Thoughts
A Non-Disturbance Clause is an essential protection for tenants, particularly those in long-term commercial leases, ensuring their occupancy rights remain intact despite changes in ownership or financial distress. By negotiating this clause into their lease, tenants can safeguard their business operations and investment in the property.
For landlords and investors, offering a Non-Disturbance Clause can be a valuable tool to attract long-term tenants, providing them with the security and confidence they need to commit to a lease. However, it is important for both parties to understand the full scope of the clause and how it can impact property rights in the event of foreclosure or a change of ownership.
