The Impact of Triple Net Leases on Tenants

A Triple Net (NNN) lease shifts nearly all property-related expenses to the tenant. In addition to base rent, tenants typically cover property taxes, insurance, maintenance, and direct costs like utilities, HVAC servicing, and janitorial services.

These leases are common for full-building users, life science facilities, and industrial properties—where operating costs can vary widely based on how the space is used. It's critical that the lease clearly defines which expenses fall to the tenant and which remain the landlord’s responsibility. Generally, tenants pay for routine operating costs, while capital improvements remain with the landlord.

Transparency is key. Tenants should carefully review property tax bills, insurance premiums, and maintenance budgets, as these directly affect their total occupancy cost. The upside to taking on these expenses is typically a lower base rent compared to gross or base-year lease structures.

Why Are Triple Net Leases Common in Life Sciences and Industrial/Flex Properties?

These sectors often involve specialized operations with higher utility and maintenance demands. For instance:

• Life science tenants may need robust HVAC systems to maintain precise lab environments.

• Industrial tenants often use heavy-duty equipment that drives up energy use.

In NNN leases, tenants pay for their actual consumption. This structure ensures operating expenses reflect each tenant's unique usage rather than being averaged across multiple occupants.

Advantages for Tenants

• Lower Base Rent: Typically, below full-service lease rates.

• More Control: Tenants can directly manage service contracts, utilities, and maintenance, potentially lowering costs.

• Usage-Based Billing: You're charged for what you use, not someone else’s share.

• Operational Efficiency: Cost-saving measures like energy improvements directly benefit your bottom line.

  
  

Risks and Trade-Offs

• Operating Cost Variability: Taxes, insurance, and maintenance are your responsibility and can change year to year.

• Administrative Burden: Managing multiple service providers and utility accounts requires additional oversight.

• Exposure to Capital Costs: Repairs or replacements, especially for systems like HVAC or roofing. may fall partially or fully on you.

• Unpredictable Cash Flow: Unlike full-service leases, monthly costs can fluctuate with the market or property conditions.

• Maintenance and Replacement Risk: You're typically required to maintain an HVAC service contract (often annual or bi-annual) and may be responsible for replacing units that are no longer operating efficiently. Clarify your obligations for HVAC systems, roofing, parking lots, and major repairs. Ask for detailed service standards and access to cost records.

Final Thoughts

A Triple Net lease can offer lower rent, more transparency, and greater control—but it also brings higher financial risk. Make sure you understand exactly what you’re agreeing to. Define responsibilities clearly, especially around maintenance and capital expenses, and ensure you have visibility into costs.

Whether your business is considering a potential relocation or negotiating a renewal, working with a tenant-only advocate, like WRA, will help to analyze total occupancy costs, secure aggressive terms, and ensure that the lease aligns with the businesses long term goals.
