BC security deposit law: the framework
Under BC RTA Section 38, a landlord must return the security deposit (less any amount the tenant owes) within 15 days of the tenancy end. If the landlord wants to retain any portion, they must file for dispute resolution within 15 days of tenancy end (or have the tenant's consent). The burden is on the landlord to prove that a deduction is justified. For pest-related deductions, that means proving: (1) there is identifiable damage or cost; (2) the tenant's conduct caused it; and (3) the deduction amount is reasonable.
What landlords can deduct for pest issues
- Cost of professional pest treatment where the landlord has documented evidence of tenant-caused infestation (e.g., undisclosed pets that caused a flea infestation, documented evidence of tenant bringing in confirmed-infested items).
- Cost of replacing items the tenant damaged by pest introduction (e.g., if a tenant's neglect led to mice gnawing structural elements beyond normal wear and tear).
- Professional cleaning costs where tenant-caused pest conditions created measurable contamination beyond normal wear and tear.
- Replacement of items documented in the move-in inspection as present and in good condition, now damaged by pests the tenant demonstrably introduced.
What landlords cannot deduct for pest issues
- Cost of treating a rodent infestation where entry points are structural — this is landlord-scope regardless of tenancy end.
- Cost of treating cockroaches in a multi-unit building where migration from other units is likely — building-wide pest pressure is not tenant fault.
- Cost of bed bug treatment absent specific evidence of tenant introduction — normal travel or secondhand furniture does not constitute fault.
- Preventive pest treatment scheduled regardless of tenant activity (e.g., quarterly service).
- Cost of structural exclusion work (sealing entry points) — this is a landlord capital obligation, not tenant damage.
| Situation | Deduction allowed? | Evidence required |
|---|---|---|
| Flea infestation from undisclosed pet in no-pets unit | Yes | Move-in report (no fleas), pet evidence, flea treatment invoice |
| Mice from structural entry points | No | N/A — landlord scope regardless |
| Bed bugs — no evidence of specific introduction | No | RTB consistently denies without specific fault evidence |
| Cockroaches in multi-unit building | No | Building-wide source; not tenant fault |
| Tenant brought confirmed-infested couch (photographic evidence) | Yes | Photo of infested item entering, treatment invoice |
| Rodent damage to unit (gnaw marks, contaminated insulation) — structural entry | No (treatment) / Partial (repair) | Structural entry = landlord treatment cost; damaged finishes may be disputed |
How RTB handles wrongful deductions: BC case patterns
RTB arbitrators have a consistent approach to contested pest-related deposit deductions: without specific documented evidence of tenant fault, the deduction is reversed. In cases where a landlord makes a pest deduction without proper documentation and the tenant disputes it, the landlord faces the risk of losing the full deposit plus paying the filing fee and, in egregious cases, a penalty under RTA Section 67 for wrongfully withholding the deposit. A landlord who deducts $800 for 'pest treatment' without documentation is typically ordered to repay the $800 plus the tenant's $200 RTB filing fee. In cases where arbitrators find the landlord acted in bad faith, additional compensation can be awarded.
Tenant protection: move-in and move-out inspections
The most effective protection against wrongful pest-related deposit deductions is a thorough move-in condition inspection that documents the state of the unit before tenancy. RTA Section 23 provides that landlords must give tenants a condition inspection report at the start of tenancy. Tenants should: (1) do the inspection personally and note any pre-existing pest evidence (droppings, gnaw marks, pest damage); (2) photograph any evidence found; and (3) ensure the report is signed and dated. If the move-in report is silent on pest evidence, and the landlord later claims tenant-caused pest damage, the tenant can argue the landlord had no prior documentation of the damage.
