Manitoba Commercial Maintenance Obligations & NNN Leases

Unlike residential tenancy, where a landlord is legally forced to guarantee the "habitability" of a property, commercial landlords in Manitoba face no such universal mandate. In commercial real estate, maintenance responsibilities are solely defined by the language constructed within the lease agreement.

Commercial landlord-tenant laws are highly dependent on the specific lease agreement. Always consult a licensed commercial real estate attorney in Manitoba. Information last verified: March 2026.

"As-Is" Commercial Properties

A hallmark of commercial leasing in Manitoba is that the lessee typically accepts the premises in an "as-is, where-is" condition. It is the tenant's responsibility to conduct structural inspections prior to signing, as they cannot hold the landlord responsible for issues discovered post-occupancy unless the defect was fraudulently hidden by the landlord, or unless explicitly guaranteed in the lease.

The Triple Net (NNN) Lease Standard

The most prevalent lease structure in Manitoba commercial real estate—particularly for free-standing buildings, retail plazas, and industrial parks—is the Triple Net (NNN) lease.

In an absolute NNN lease, the tenant is financially responsible for virtually everything:

• Net 1 (Taxes): All property taxes and assessments.
• Net 2 (Insurance): Both the tenant's commercial liability and covering the building's property insurance.
• Net 3 (Maintenance): Complete maintenance of the interior and exterior of the building, including capital repairs like a failing roof or a cracked parking lot.

Often, NNN leases are slightly modified. The most common arrangement leaves the landlord responsible for "structural components" (the foundation, load-bearing walls, and the roof membrane), while the tenant assumes responsibility for everything else, including mechanical systems.

Special Focus: HVAC Obligations

Disputes over Heating, Ventilation, and Air Conditioning (HVAC) systems are notoriously common in commercial leasing.

• Tenant Maintenance: Leases often mandate that the tenant secure a quarterly preventative maintenance contract for the HVAC units with an approved service provider.
• Replacement: If an aging unit dies on a hot summer day, the lease dictates who pays for the $15,000 replacement. Landlords frequently attempt to push full replacement costs onto commercial tenants, while savvy tenants negotiate caps on their liability for capital replacements.

Tracking TMI and CAM Charges

In multi-tenant buildings (like a strip mall or office tower), the landlord directly performs exterior maintenance, snow removal, security, and cleaning of common lobbies.

These costs are grouped as Common Area Maintenance (CAM) or Taxes, Maintenance, and Insurance (TMI). The landlord invoices each tenant for their proportionate share of these expenses, usually requiring monthly estimated prepayments and performing an annual reconciliation audit.

Centralizing Maintenance with Landager

Auditing CAM expenses and verifying that tenants are actively upholding their required HVAC maintenance contracts are heavy administrative burdens. Landager’s commercial platform aggregates all property-level expenses for seamless CAM reconciliations, while simultaneously tracking tenant preventative maintenance obligations, automatically notifying them when their mandated HVAC service reports are due to be uploaded.
