Unlike residential tenancies-where the landlord has a non-waivable duty to maintain habitability-commercial maintenance responsibilities in Minnesota are dictated almost entirely by the lease agreement. The allocation of repair duties is a key negotiation point and varies dramatically depending on the lease structure.

Official Law Citation: Commercial maintenance obligations are solely dictated by the commercial lease agreement. The residential covenants of habitability do not apply.

No Implied Warranty of Habitability

The residential implied warranty of habitability (including the 68°F heat rule and pest extermination duty) does not apply to commercial leases in Minnesota. A commercial property is typically leased "as-is," and maintenance duties are allocated entirely by the signed lease agreement.

Maintenance by Lease Type

Triple Net (NNN) Lease

• Landlord: Typically responsible only for structural elements (foundation, exterior walls, structural roof members).
• Tenant: Responsible for essentially everything else-interior repairs, HVAC maintenance, plumbing, electrical, parking lot, landscaping, snow removal, roof membrane, and even some structural repairs depending on the lease.

Gross / Full Service Lease

• Landlord: Maintains the building's exterior, roof, HVAC systems, elevators, common areas, and all base building systems.
• Tenant: Typically responsible only for their interior suite-basic cleaning, cosmetic maintenance, and any tenant-installed fixtures or equipment.

Modified Gross Lease

• A hybrid arrangement where the parties negotiate which specific maintenance items fall to each party.

Common Area Maintenance (CAM)

In multi-tenant commercial properties, the landlord typically arranges and manages maintenance of common areas (parking lots, lobbies, hallways, restrooms, landscaping). The cost is then charged back to tenants as CAM charges, allocated on a pro-rata basis by square footage.

The lease should clearly define:

• What expenses are included in CAM.
• Whether CAM charges have a cap (a "CAM cap").
• The annual reconciliation process.

Minnesota's Cold Climate Considerations

Minnesota's extreme winters create unique commercial maintenance challenges:

• Snow Removal: Who is responsible for plowing parking lots and shoveling sidewalks? This must be clearly defined, as slip-and-fall injuries create significant liability.
• Heating Systems: In a NNN lease, the tenant is typically responsible for maintaining the heating system-a critical and potentially expensive obligation in Minnesota's sub-zero winters.
• Freeze Protection: Pipes, sprinkler systems, and water lines must be properly insulated. Responsibility for damage from frozen/burst pipes should be explicitly addressed.

Best Practices for Minnesota Commercial Landlords

• Be Specific About "Structural": Clearly define which items are "structural" (landlord's responsibility) vs. "non-structural" (tenant's responsibility). Is the roof membrane structural? Is the parking lot surface? Ambiguity leads to disputes.
• Require HVAC Maintenance Contracts: If the tenant is responsible for HVAC, require them to maintain a professional maintenance contract and provide annual proof.
