What Are the Legal Aspects of Leasing Commercial Property?
Leasing commercial properties is a critical aspect of real estate that demands attention to legal details to ensure that both landlords and tenants can protect their interests. These legal aspects are often complex and require careful consideration. Commercial leases, unlike residential leases, come with specific legal nuances that cater to businesses and commercial operations. From rent and maintenance obligations to rights and dispute resolutions, there are various factors that must be clearly defined in the lease agreement. In this blog, we will explore the most important legal considerations when leasing commercial property, including types of leases, crucial clauses, and tenant and landlord rights.

Types of Commercial Leases
When leasing commercial property, the type of lease chosen plays a significant role in determining the financial and operational responsibilities of both the tenant and the landlord. Understanding the different lease structures is essential for making informed decisions.
1. Gross Lease
A gross lease is one of the most straightforward and commonly used lease structures, especially for office spaces. Under a gross lease, the tenant agrees to pay a fixed rent amount, and the landlord is responsible for covering all the operational expenses of the property. These expenses can include property taxes, building insurance, maintenance, utilities, and other operational costs. The tenant benefits from predictable rent costs, while the landlord assumes the risk of fluctuating operational costs. The gross lease can be particularly attractive to businesses that do not want to deal with fluctuating operational costs or expenses that vary over time.
For landlords, this lease type provides them with steady and predictable income, but they must bear the risk of increased operational costs. However, gross leases can be beneficial in properties where the landlord has more control over these costs or can negotiate favorable rates with service providers.
2. Net Lease
Net leases are more common in industrial, retail, and certain office spaces. In a net lease, the tenant pays a base rent, and in addition, they are responsible for some or all of the property’s operating expenses. These expenses typically include property taxes, insurance, and maintenance. Net leases can be classified into three types:
- Single Net Lease: In this lease, the tenant pays the base rent plus property taxes. The landlord is still responsible for maintaining the insurance and upkeep of the property.
- Double Net Lease: The tenant pays for both property taxes and insurance, while the landlord remains responsible for maintenance.
- Triple Net Lease (NNN): The most common form in retail and industrial leasing, this type of lease requires the tenant to pay property taxes, insurance, and maintenance expenses, along with the base rent. The tenant thus assumes the majority of the financial responsibility for the property.
Triple net leases are beneficial for landlords as they transfer most of the costs to the tenant, reducing the landlord’s exposure to fluctuations in operational expenses. However, this type of lease can lead to higher costs for tenants, who must budget for additional expenses on top of rent.
3. Percentage Lease
A percentage lease is frequently used in retail leasing, particularly for businesses that rely on consumer traffic, such as malls, shopping centers, and franchise stores. Under this arrangement, the tenant agrees to pay a base rent plus a percentage of their gross sales, with the percentage typically ranging from 5% to 10%. The idea behind this lease structure is that the landlord benefits directly from the tenant’s business success.
For tenants, the percentage lease allows for flexibility, especially during slow periods when paying a fixed rent might be burdensome. Instead, they pay a portion of their sales, which fluctuates with their business performance. This can be an attractive option for tenants who are just starting or those who experience seasonal fluctuations in sales.
From a landlord’s perspective, this lease provides the potential for higher rent if the tenant is successful, aligning the interests of both parties in fostering a profitable business environment.
Essential Clauses in Commercial Leases
The key to a successful commercial lease lies in having well-drafted clauses that outline each party’s responsibilities and expectations. A comprehensive lease agreement helps avoid disputes and provides a clear structure for the relationship between the tenant and the landlord.
1. Rent and Rent Escalation
The rent clause is one of the most important components of any lease. It clearly defines the amount of rent, the due dates, and whether the rent is subject to escalation over the course of the lease. Rent escalation clauses are particularly important as they define how rent will increase. This increase can be tied to inflation, a fixed percentage, or based on market conditions. The specific terms for rent escalation should be negotiated and clearly defined to avoid surprises later in the lease term.
Rent escalation can be tied to various indices, such as the Consumer Price Index (CPI), which ensures that the rent keeps pace with inflation. Alternatively, it can be scheduled on specific dates, such as every 3 or 5 years, to adjust according to market rent trends.
2. Lease Term
The lease term specifies the length of time the tenant will occupy the property. A lease may be for a fixed period, such as one, three, or five years, or it may offer the possibility of renewal. The lease should clearly outline the process for renewing the lease, including the notice period and the terms for renewal.
For both parties, the lease term is critical. Tenants want the stability of knowing how long they can occupy the property, while landlords seek to secure long-term income from the lease. Some leases also allow tenants to break the lease early under certain conditions, which provides them with flexibility.
3. Use Clause

The use clause defines the purpose for which the tenant may use the leased property. This clause ensures that the tenant’s activities comply with zoning laws and other legal requirements. For example, a commercial lease may restrict the tenant to using the space for retail, office, or industrial purposes only.
Landlords include use clauses to protect the property’s value and ensure that tenants do not engage in activities that could harm the property or violate local regulations. It is also essential for the tenant, as it provides clarity about the permissible business activities within the space.
4. Maintenance and Repairs
This clause outlines the responsibilities of the tenant and landlord regarding the upkeep of the property. Generally, tenants are responsible for maintaining the interior of the leased space, including repairs and upkeep of the premises. Landlords, on the other hand, are usually responsible for maintaining the exterior of the property, including structural repairs and common areas such as hallways, parking lots, and elevators.
It’s essential to clearly define the scope of each party’s responsibilities to avoid confusion and prevent disputes regarding maintenance duties.
5. Security Deposit
A security deposit is typically required at the start of a lease to cover potential damages or unpaid rent. The amount of the deposit, conditions for its use, and the procedure for returning it to the tenant at the end of the lease term should be clearly outlined in the lease agreement. The lease should also specify the duration for which the landlord can retain the deposit, as well as any circumstances under which it may be forfeited.
6. Subleasing and Assignment
Subleasing and assignment clauses allow or restrict the tenant’s ability to transfer their lease rights to another party. In a sublease, the tenant rents out part or all of the space to another entity while maintaining responsibility for the lease. An assignment transfers the tenant’s entire interest in the lease to another party.
Landlords often restrict or prohibit subleasing or assignment to maintain control over who occupies the property. These clauses should be carefully negotiated, as they can have significant implications for the tenant’s ability to exit the lease early or change their business operations.
7. Termination and Default
This clause defines the circumstances under which the lease can be terminated by either party. It also specifies the remedies available to the non-breaching party in the event of a default. A default can occur if either the landlord or tenant fails to fulfill their obligations under the lease. Remedies may include the right to terminate the lease, collect damages, or retain the security deposit.
Tenant Rights and Protections
While commercial tenants do not enjoy the same legal protections as residential tenants, they still have certain rights under the lease agreement and local laws. These rights include the right to occupy the space without interference, the right to peaceful enjoyment, and the right to have access to essential utilities.
Tenants also have the right to challenge any unlawful rent increases, seek remedies for breaches of the lease, and request necessary repairs if the property is not in a habitable condition. In many jurisdictions, laws may protect tenants from unfair eviction or retaliation from landlords.
Conclusion
Leasing commercial property is a multifaceted legal process that requires careful attention to detail. By understanding the types of leases, the essential clauses in the agreement, and tenant rights, both landlords and tenants can create a mutually beneficial and legally sound leasing arrangement. A well-drafted lease protects both parties’ interests, provides clarity, and helps avoid disputes. Whether you’re a landlord or tenant, taking the time to understand these legal aspects will ensure a smooth and successful leasing experience.
