Caulking Replacement in NNN Lease: Who Pays – Tenant or Landlord? A Practical Guide for Tenants and Landlords
In the world of commercial leasing, few agreements shift as much responsibility to the tenant as the triple net (NNN) lease. Under this structure, the tenant covers property taxes, insurance, and all maintenance and repairs—often down to the smallest details. But when it comes to caulking replacement NNN lease obligations, who foots the bill?
The short answer: Usually the tenant. But as with most things in real estate, it depends. Let’s break it down.
Caulking Replacement NNN Lease: Tenant’s Routine Maintenance Duties
In a standard NNN lease, the tenant is on the hook for day-to-day upkeep. That includes caulking replacement NNN lease when it fails due to:
- Normal wear and tear (aging, drying out, or cracking over time)
- Improper cleaning or use
- Aesthetic degradation (peeling, discoloration, or unsightly gaps)
Why This Matters: Preventing Bigger Problems
Caulking isn’t just cosmetic—it’s a first line of defense against water intrusion. A small crack today can become a major leak tomorrow, leading to mold, drywall damage, or compromised insulation.
Pro Tip for Tenants: Pro Tip for Tenants: Don’t wait for a leak to act. Addressing caulking replacement NNN lease early prevents you from being liable for much larger repair bills down the line.
Think of it like changing the oil in your car. Skip it, and you’re not just replacing oil—you’re replacing the engine.
The Landlord’s Responsibility: Structural and Systemic Issues
While tenants handle routine fixes, landlords retain responsibility for structural components. That means caulking replacement falls on the landlord if the failure stems from:
1. Structural Movement
- Foundation settling
- Wall shifting or expansion/contraction
- Roof or framing issues causing gaps
In these cases, the landlord must fix the root cause and the resulting caulking.
2. Pre-Existing Conditions
- If caulking was already failing when the tenant moved in—and the landlord knew (or should have known)—it’s the landlord’s problem.
3. Building Envelope in Multi-Tenant Properties
- In many multi-tenant NNN leases, the landlord maintains the roof and exterior envelope, including structural caulking on outer walls.
- Exception: In a true absolute NNN lease, even exterior envelope maintenance may pass to the tenant. Always check the fine print.
