Multi-tenant office pest control: who pays, who calls, and who's liable in BC commercial leases

How BC commercial leases handle pest management

BC commercial leases do not follow a standardized template for pest management responsibility — terms vary significantly between landlords, building classes, and property types. However, the most common pattern in Metro Vancouver office buildings follows the CAM (Common Area Maintenance) charge framework: the landlord maintains common areas, the building structure, and the perimeter, with costs recovered through CAM charges billed proportionally to tenants. Individual tenant suites are the tenant's maintenance responsibility. Pest management that originates in common areas (a cockroach infestation in a shared utility corridor) is typically the landlord's responsibility; pest management that originates within a tenant suite (a cockroach infestation in a tenant's kitchenette) is typically the tenant's responsibility. In practice, determining origin is difficult and contested when an infestation spans multiple areas.

Reading your lease: the clauses that matter

• Maintenance and repair obligations: look for language specifying tenant obligations to maintain the premises 'in a clean and sanitary condition' — this typically includes pest management in the tenant suite.
• Common area maintenance definitions: what is included in the building's CAM scope? If 'pest control' or 'extermination' appears in the list of CAM services, building-level pest control may be included in your CAM charges.
• Landlord's obligations: does the lease specify the landlord's obligation to maintain the building structure, including pest-exclusion elements (door seals, window screens, structural integrity)? Structural pest management is typically landlord-responsible.
• Notice and remedy provisions: what is the timeline for the landlord to remedy a condition in the common areas after written notice? This governs your ability to require the landlord to address a building-level pest problem.
• Indemnification and liability: if a pest event originating in one tenant's suite causes damage or business interruption to an adjacent tenant, who bears liability? Lease indemnification clauses may allocate this.
• Environmental provisions: some commercial leases include environmental maintenance clauses that encompass pest control as part of maintaining a 'healthy' or 'safe' premises condition.

The property management coordination challenge

German cockroach infestations in multi-tenant office buildings illustrate the coordination challenge perfectly. The source suite may be a food service tenant on the ground floor whose kitchenette void has been infested for years. Cockroaches migrate upward through shared plumbing chases and HVAC connections to office suite kitchenettes on higher floors. The upper-floor tenants receive bills for German cockroach treatment in their suites — but the treatment provides only temporary suppression because the source suite continues to produce cockroaches. Resolving the building-level infestation requires: identifying the source suite, coordinating access across multiple tenant leases, treating the source and the migration pathways simultaneously, and monitoring across affected floors to verify resolution. This is structurally impossible without property management coordination and a building-wide pest management program.
