Grounded in the foundational property and contract rights established by the Tennessee Constitution (effective February 6, 1796), commercial real estate in Tennessee operates under a fundamentally different legal framework than residential leasing. In residential Tennessee real estate (especially URLTA counties like Davidson or Shelby), the landlord securely bears the heavy burden of the "implied warranty of habitability." In commercial real estate, this warranty simply does not exist.
If the roof leaks onto a commercial tenant's inventory, or the HVAC fails in July, the responsibility to fix it—and pay for the damage—is determined entirely by the maintenance clauses written into the commercial lease.
The NNN Lease: Tenant Bears the Load
In a standard Triple Net (NNN) lease (the most common structure for retail spaces, restaurants, and single-tenant industrial buildings in Tennessee), the commercial tenant contractually assumes nearly all maintenance responsibilities.
The Tenant's Responsibilities
In an NNN scenario, the tenant must reliably repair, maintain, and replace:
- Interior walls, paint, and flooring.
- Plumbing and electrical systems within the suite.
- The HVAC System: This is a notoriously critical negotiating point. Often, tenants are assigned full responsibility for the HVAC unit servicing their suite, including costly total replacements. (Savvy tenants negotiate absolute caps on their annual HVAC liability, or require the landlord to replace units past their usable lifespan).
- Janitorial services and interior pest control.
The Landlord's Responsibilities (Structural/Exterior)
Even in an NNN lease, the landlord typically retains responsibility for:
- The "structural elements" of the building (foundation, load-bearing walls).
- The roof (both the membrane and structural supports).
- Exterior walls.
- Common Areas (parking lots, landscaping, shared lobbies).
Common Area Maintenance (CAM) Charges
While the landlord performs the maintenance on the common areas and building exterior, the cost of that maintenance is passed directly to the tenants in a NNN lease via CAM charges.
- Each commercial tenant pays a "pro-rata share" based on the square footage they occupy compared to the total leasable area of the building.
- If a strip mall has four identical stores, each tenant pays 25% of the snow removal, parking lot sweeping, landscaping, and exterior lighting costs.
CAM Audits: Commercial tenants should enthusiastically negotiate the right to audit the landlord's CAM expenditures annually to ensure they are not being overcharged or illegally billed for capital improvements (like a completely new roof) that should be amortized or paid solely by the landlord.
The Gross Lease: Landlord Bears the Load
In a full-service Gross lease (common in multi-tenant high-rise office buildings in major Tennessee cities), the paradigm flips entirely. The landlord takes on almost all maintenance responsibilities, including the interior of the tenant's suite.
- The tenant's rent is significantly higher to cover these built-in service costs.
- The tenant is generally only responsible for avoiding negligent damage and perhaps maintaining specialized equipment related to their specific business.
End-of-Lease "Make Good" Clauses
Commercial tenants must review the lease's "surrender" or "restoration" clause. When the lease ends, the tenant is usually required to return the premises in "broom clean" condition, minus normal wear and tear.
- However, the landlord often reserves the right to demand the tenant rip out all tenant improvements (partition walls, custom lighting, specialized plumbing) and manually restore the unit back to a "vanilla shell" at the tenant's expense.

Frequently Asked Questions
▶What are the Tennessee landlord-tenant laws every property owner should know?
Residential landlord-tenant relationships in Tennessee are unique because the state operates on a two-tiered legal system. Understanding which set of laws applies to your property is the first, critical step to ensuring compliance. This guide covers the essential compliance requirements for property owners and landlords.
Read the complete guide▶What is the Tennessee eviction process and how long does it take?
The Tennessee eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Tennessee. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Tennessee security deposit rules and return deadlines?
Tennessee has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Tennessee rent increase laws and caps for landlords?
Tennessee has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Tennessee has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Tennessee?
Tennessee has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable.

Read the complete guide▶What disclosures must Tennessee landlords provide to tenants?
Tennessee landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
Read the complete guide▶What are the Tennessee lease requirements for rental properties?
Tennessee recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Tennessee law.
Read the complete guide▶What are Tennessee landlord maintenance obligations and habitability standards?
Tennessee landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control. Tenants typically have the right to request repairs in writing, and if repairs are not made within a reasonable time, tenants may have legal remedies available.
