In a triple net lease (NNN), which of the following expenses is the tenant typically NOT responsible for paying?

Triple net leases (NNN) represent a fundamental commercial leasing structure where tenants assume responsibility for the three primary operating expenses: property taxes, building insurance, and common area maintenance. This arrangement shifts operational cost burdens from landlords to tenants, making it particularly attractive to property investors seeking predictable income streams. The 'net' terminology indicates expenses beyond base rent that tenants must pay. Understanding NNN leases is crucial for commercial real estate professionals as they're prevalent in retail, office, and industrial properties. The distinction between operating expenses (tenant responsibility) and financing obligations (landlord responsibility) is critical. Mortgage payments remain the landlord's obligation because they represent debt service on the property acquisition, not operational costs. This principle protects tenants from the landlord's financing decisions while ensuring landlords maintain ownership responsibilities. Canadian commercial leasing follows similar principles across provinces, though specific regulations may vary under provincial commercial tenancy acts.
