In the dynamic commercial real estate market of South Florida—stretching from the bustling warehouses of Doral and Medley to the established industrial zones of Hialeah and Opa-locka—navigating lease agreements can feel like translating a foreign language. One term you will encounter constantly is the NNN lease. Whether you are a business owner searching for a new operational base, a landlord looking to secure a property, or an investor building a portfolio, understanding this structure is vital to your financial success.
A triple net lease is one of the most common agreements used in commercial real estate, especially for freestanding retail buildings and industrial warehouses. It shifts the day-to-day financial responsibilities of property ownership from the landlord to the tenant. Because the stakes are high and operating expenses in South Florida can fluctuate significantly, both parties must understand exactly what they are signing.
This guide breaks down the mechanics of the triple net lease, explores the benefits and risks for both landlords and tenants, and offers real-world examples to help you make informed decisions.
What is a triple net (NNN) lease?
In a standard commercial lease, the tenant pays a flat rent, and the landlord handles the building’s operating expenses. An NNN lease works differently. Under this agreement, the tenant pays a lower base rent to the landlord, but also agrees to pay their pro-rata share of the property’s three primary ongoing operating expenses, known as the “three nets.”
The three nets that define this agreement are:
- Property taxes: The tenant pays the real estate taxes assessed on the property by the local municipality or county.
- Building insurance: The tenant pays the insurance premiums required to protect the building against damage, liability, and regional environmental risks.
- Common Area Maintenance (CAM): The tenant covers the costs associated with maintaining, repairing, and operating the shared spaces of the property. This includes landscaping, parking lot repair, security, trash removal, and exterior lighting.
Because the tenant absorbs these three operating costs directly, the base rent in an NNN agreement is typically lower than in a gross lease. The landlord essentially receives a “clean” rent check that is largely unaffected by rising taxes or insurance rates, while the tenant gains more transparency and control over how the property is maintained.
The benefits of triple net investments
For those looking to build wealth in commercial real estate, triple net investments are highly sought after. They offer a unique combination of stability, predictability, and minimal management responsibilities.
For landlords and investors
The primary appeal of investing in triple net properties is the passive nature of the income stream. Because the tenant is legally responsible for taxes, insurance, and maintenance, the landlord does not have to deal with the daily headaches of property management. This makes NNN properties an ideal vehicle for hands-off investors, family offices, and those executing 1031 tax-deferred exchanges.
Additionally, NNN agreements protect landlords from inflation and rising operational costs. If property taxes spike or insurance premiums climb—as they frequently do in coastal regions like South Florida—the financial burden is passed directly to the tenant. This ensures that the landlord’s net operating income (NOI) remains highly predictable over the life of the lease.
Because NNN leases are typically long-term agreements—often lasting 10 to 15 years with built-in rent escalations—they provide investors with an exceptionally stable source of cash flow.
For tenants
While paying for taxes, insurance, and maintenance might sound disadvantageous to a tenant, the NNN structure offers distinct operational benefits.
First, the base rent is substantially lower than what you would pay under a gross lease. Second, you gain complete transparency. Instead of paying a flat rent where the landlord might overcharge for estimated operating expenses, you pay the actual, documented costs of the property. If you manage your utility usage, keep maintenance costs low, and negotiate fair vendor contracts, you can directly lower your monthly overhead.
Finally, established businesses appreciate the control that NNN leases provide. You can manage the property’s appearance to match your corporate branding, choose your preferred maintenance contractors, and ensure that your operating environment meets your exact standards.

Potential risks of triple net properties
No real estate strategy is entirely without risk. While triple net properties offer incredible advantages, both parties must prepare for potential challenges before signing on the dotted line.
For landlords
The greatest risk for a landlord in an NNN lease is tenant default. Because NNN properties are often occupied by a single tenant, a vacancy means your income drops to zero instantly. Furthermore, when the building is empty, the landlord must assume full responsibility for the property taxes, insurance, and maintenance costs until a new tenant is secured.
Additionally, landlords are typically still responsible for “roof and structure” repairs. If the building requires a brand-new roof, foundation work, or structural utility overhauls, these major capital expenditures (CapEx) cannot usually be passed on to the tenant under a standard NNN agreement, unless specifically negotiated.
For tenants
For tenants, the primary risk of an NNN agreement is the unpredictability of operating expenses. In South Florida, property insurance premiums and real estate taxes can rise rapidly due to climate factors, legislative shifts, and fast-paced commercial valuations. If your insurance costs double in a single year, your total monthly housing cost will spike, regardless of your business’s actual performance.
Furthermore, if the common area equipment—such as an expensive HVAC system—breaks down, the tenant is often responsible for its repair or replacement under CAM terms. A sudden major repair can create unexpected cash flow strain for a growing business.
Real-world examples in the South Florida market
To understand how an NNN lease translates into monthly numbers, let’s look at a typical industrial asset in a popular submarket like Doral or Medley.
Imagine a business owner leasing a +/- 20,000-square-foot warehouse in a modern logistics park. The landlord offers a base rent of +/- $16.00 per square foot NNN. However, the estimated operating expenses (the three nets) for the property are calculated at +/- $5.50 per square foot.
To find the annual base rent, you multiply the square footage by the base rate: +/- 20,000 square feet multiplied by +/- $16.00 equals +/- $320,000 per year (+/- $26,666.67 per month).
To find the annual operating expenses, you multiply the square footage by the NNN rate: +/- 20,000 square feet multiplied by +/- $5.50 equals +/- $110,000 per year (+/- $9,166.67 per month).
Adding these two figures together, the tenant’s total annual commitment is +/- $430,000, resulting in a total monthly payment of +/- $35,833.34. The tenant will write a check to the landlord covering both the base rent and the escrowed NNN charges, which the landlord then uses to pay the taxes, insurance, and maintenance bills.
This dynamic is incredibly common across premier logistics parks. For instance, if you look at the highly active Miami Airport North submarket profile, you will find that tight vacancy rates and a lack of new space keep NNN rates competitive, making it crucial for tenants to understand how these extra charges impact their overall budget before committing to a lease.
Key clauses to watch in an NNN agreement
Because NNN leases shift substantial financial responsibility to the tenant, a well-negotiated contract is essential. Whether you are representing the landlord or the tenant, pay close attention to these critical clauses:
1. Capital expenditures vs. maintenance
The lease must clearly define what constitutes a standard maintenance expense (which the tenant pays) versus a structural capital expenditure (which the landlord pays). For example, if an HVAC unit needs standard servicing, that is a tenant expense. If the entire multi-ton roof-mounted unit dies and needs a full replacement, the cost should ideally be amortized over the unit’s useful life, with the tenant only paying for the portion of life used during their lease term.
2. The CAM cap
Tenants should always negotiate a “CAM Cap” to protect themselves from sudden spikes in maintenance costs. A standard clause limits the annual increase in controllable common area maintenance expenses to a set percentage, such as 5% to 8% per year. This prevents landlords from performing massive, non-essential renovations and passing the bill directly to the tenant in a single year.
3. Audit rights
A fair lease agreement gives the tenant the right to audit the landlord’s operating expense records once a year. This ensures that the taxes, insurance, and CAM fees being charged are accurate, verified, and directly related to the operation of the leased premises.
FAQs
What is the difference between single, double, and triple net leases?
The difference lies in how many of the “nets” are paid by the tenant. In a Single Net (N) lease, the tenant pays rent plus property taxes. In a Double Net (NN) lease, the tenant pays rent, property taxes, and building insurance. In a Triple Net (NNN) lease, the tenant covers all three: taxes, insurance, and common area maintenance.
Who pays for structural repairs, like the foundation or roof, in an NNN lease?
In a standard NNN lease, the landlord remains responsible for major structural repairs, including the foundation, load-bearing walls, and the roof deck. However, some “absolute NNN” leases exist where the tenant assumes responsibility for absolutely all repairs, including structural elements. Always check the specific definitions in your contract.
Why are NNN leases so popular for industrial real estate in South Florida?
Industrial tenants—such as logistics companies, importers, and manufacturers—often require highly specialized setups. They prefer NNN leases because it gives them control over their facility’s maintenance and security. For landlords, the structure offers a predictable, hands-off income stream in a region with rapidly changing tax and insurance costs.
Can CAM charges fluctuate during the lease term?
Yes. Because CAM charges represent the actual costs of maintaining the property, they can rise or fall based on the cost of utilities, landscaping services, security contracts, and unexpected repairs. Tenants should review previous years’ CAM audits to anticipate these fluctuations.
Navigating the nuances of commercial lease structures requires local expertise and a clear understanding of your long-term goals.
