A Triple Net Lease—commonly referred to as an NNN lease—is one of the most widely used lease structures in commercial real estate. In this arrangement, the tenant takes on responsibility for three major property expenses: property taxes, insurance, and maintenance, in addition to paying base rent.

Whether you’re an investor exploring commercial leasing options or a business owner seeking the ideal space, understanding the intricacies of Triple Net Leases is crucial. Our comprehensive guide covers everything from the basics to the finer details of NNN leases, equipping you with the insights needed to make informed decisions in the commercial real estate market.

What Is a Triple Net Lease (NNN) and What Does NNN Mean?

A Triple Net Lease (NNN) is a lease agreement commonly found in commercial real estate, where the tenant agrees to cover nearly all operating expenses—including taxes, building insurance, and maintenance—in addition to rent. The term “NNN” stands for the three ‘nets’: property taxes, insurance, and maintenance costs.

In an NNN lease—or triple net lease—the landlord typically remains responsible only for major structural elements, such as the roof, foundation, and exterior walls. Meanwhile, the tenant assumes nearly all operational costs, including:

  1. Property Taxes: Paid directly by the tenant
  2. Insurance: The tenant covers property insurance premiums
  3. Maintenance: Tenants handle day-to-day upkeep, minor repairs, and ongoing maintenance tasks

What is The Concept of NNN?

The concept of an NNN or Triple Net Lease refers to a commercial leasing agreement where the tenant is responsible for three major categories of expenses in addition to their regular rent.

In essence, the NNN lease shifts the burden of many property ownership expenses from the landlord to the tenant, allowing the landlord to receive a more predictable income without the uncertainties of variable property-related costs.

NNN Lease vs Net Lease

When comparing a net lease vs. NNN lease, it helps to understand that “net lease” is a broader category, while NNN (triple net) lease is a specific type.

  1. NNN Single Net Lease (N): Tenant pays base rent + property taxes
  2. Double Net Lease (NN): Tenant pays rent + taxes and insurance
  3. Triple Net Lease (NNN): Tenant pays rent + taxes, insurance, and maintenance (Triple Net Lease):

Think of it like this:

A single net lease is like renting a car and only paying for fuel. A double net lease adds insurance. A triple net lease means you cover everything—from gas to maintenance and insurance.

Triple Net Lease Considerations

Although the triple net lease is a highly favored and prized form of a commercial real estate lease, it might not always work in the landlord’s favor. 

Putting the responsibility on the occupant takes the control out of the owner’s hands, and because of that, there are important considerations to be made – by all parties – for every one of the three charges that the tenant will deliver.

  1. Maintenance – establishing the level of maintenance will set the terms of the lease requirements. If a tenant allows a property to deteriorate, that will decrease the property’s value. This is something that every landlord will need protection from.
  2. Insurance – Outlying the amount of insurance will be required. Again, if a tenant cheaps out on the insurance, or doesn’t acquire it at all, then the property owner might end up in a lot of trouble should some catastrophe strike.
  3. Taxes – If an unfair appraisal of the proprietary taxes comes, the landlord can contest it, but since he is not the one paying the bill, he might as well not bother. Likewise, a tenant could leave before taxes are due, and the landlord will be stuck with the bill, so if you’ve ever wondered what does landlord pay in triple net lease – there’s the answer.

Why Do Landlords Prefer Triple Net Leases?

NNN leases help landlords reduce risk by shifting most variable costs—like property taxes and maintenance—onto the tenant. This setup makes income from a triple net property more stable and predictable.

If insurance premiums or property taxes increase, the landlord isn’t responsible for the added expense. That’s why NNN real estate is a popular option among long-term CRE investors.

How the Triple Net Lease Favors the Tenant

The triple net lease presents a unique advantage for tenants, offering a blend of autonomy and potential cost savings. At its core, this leasing model often results in a lower base rent, as tenants assume the costs of taxes, insurance, and maintenance. This trade-off can be particularly favorable for businesses seeking financial predictability and control over their operating expenses.

Within the scope of NNN leases, savvy negotiation can lead to even more tenant-friendly terms. Landlords, for instance, might be willing to absorb certain expenses, such as specific utility costs or targeted property improvements. This flexibility is a hallmark of the Triple Net Lease, empowering tenants to tailor the agreement to their specific needs.

For those in single-tenant NNN leases, the benefits extend further.

With the responsibility for insurance and maintenance in your hands, you gain the freedom to shop for the best deals and prioritize repairs and upkeep according to your business needs and budget. While the terms of a Triple Net Lease do set some boundaries, they often grant you more say in how to manage and budget for property-related costs, rather than being at the mercy of the landlord’s discretion. This level of control is a significant reason why many tenants find the Triple Net Lease an attractive option in commercial real estate.

What if There Are Multiple Tenants?

When it comes to Triple Net Leases (NNN) involving multiple tenants, the dynamics shift slightly.

In such scenarios, each tenant typically has a proportionate share of the total building expenses, based on their leased square footage or a pre-agreed formula. This means that the costs of taxes, insurance, and maintenance are divided among all tenants, rather than being the sole responsibility of a single tenant.

Managing a multi-tenant NNN lease requires clear communication and precise allocation of expenses to ensure fairness and transparency. Landlords often streamline this process by providing detailed breakdowns of shared costs and ensuring that each tenant understands their financial obligations under the lease terms.

In a multi-tenant setting, negotiation still plays a crucial role. Tenants may collectively or individually negotiate aspects of the lease, particularly around common area maintenance and shared facility upgrades. It’s important for each tenant to understand how their lease terms and the collective lease terms interact, as this can impact their overall costs and responsibilities.

Ultimately, while multi-tenant NNN leases involve additional layers of coordination and calculation, they can still offer the benefits of a predictable cost structure and shared responsibility for property upkeep, making them a viable option for businesses in a shared commercial space.
