Quebec Commercial Maintenance Obligations & Liability

In the commercial real estate world, the rules of maintenance and habitability flip entirely. Unlike residential leasing, where the landlord is strictly liable for almost all repairs, commercial leases in Quebec allow the landlord to offload the vast majority of physical maintenance to the tenant.

The Default Rules (Civil Code of Québec)

If a commercial lease is entirely silent on maintenance—a rare scenario—the default rules of the Civil Code of Québec (CCQ) apply. Under Article 1854, the landlord must:

1. Deliver the property in good repair.
2. Provide peaceful enjoyment of the premises.
3. Perform all necessary repairs, except for minor maintenance work which falls to the tenant.

If a commercial lease relies on these default rules, the landlord is still legally stuck replacing the HVAC system, fixing the roof, and paving the parking lot.

Contracting Out of the Default Rules (Triple Net)

The true power of a commercial lease lies in the freedom to draft clauses that completely override the Civil Code's default maintenance rules.

In a standard "Triple Net" (NNN) commercial lease, the tenant is made entirely responsible for the premises. The lease will explicitly state that the property is leased on a "carefree absolute net basis" to the landlord.

Tenant Responsibilities in an NNN Lease

• Routine maintenance (cleaning, light bulbs, minor plumbing).
• HVAC maintenance and replacement.
• Plate glass insurance and replacement.
• Snow removal and landscaping.
• Interior build-outs and aesthetic repairs.

The Structural Exception

Even in a heavily tenant-favorable Triple Net lease, the landlord is typically still responsible for "major structural repairs." This usually encompasses the foundation, load-bearing walls, and the replacement of the roof membrane, though aggressive leases will attempt to categorize even roof replacement as an operating expense to be shared among tenants.

Tenant Improvements (Fixturing)

Commercial tenants nearly always need to customize a raw space to fit their business (e.g., installing a kitchen for a restaurant, erecting walls for medical offices). These are known as tenant improvements or leasehold improvements.

The lease must clearly outline:

• Approval: The landlord must have the right to approve all architectural plans before work begins to ensure structural integrity and code compliance.
• Ownership: Upon the expiration of the lease, do the improvements become the property of the landlord, or must the tenant tear them down and restore the unit "to base building condition"?
• Legal Hypothecs (Construction Liens): If a tenant hires a contractor to build out the space and fails to pay them, the contractor can register a legal hypothec (lien) against the landlord's building under Quebec law. Therefore, commercial landlords usually require tenants to prove they have paid all contractors before releasing any tenant-improvement allowances.

Peaceful Enjoyment in a Commercial Context

Even in a Triple Net lease, a commercial landlord can be found liable for breaching the tenant's right to "peaceful enjoyment."

For example, if the landlord is undertaking major renovations in a neighboring unit that generates extreme, continuous noise and dust—forcing a dental clinic tenant to cancel appointments for a month—the commercial tenant can sue the landlord for damages and lost revenue.

How Landager Helps

Managing commercial maintenance requests and allocating correct vendor costs requires precision. Landager's maintenance portal helps categorize whether a repair ticket falls under a tenant's responsibility or the landlord's structural liabilities, ensuring you aren't paying for repairs your Triple Net lease explicitly assigned to the tenant.
