Deposit Limits
| Aspect | Commercial | Residential (Business) |
|---|---|---|
| Statutory cap | None | 1 month's rent |
| Market practice | 3–6 months | 1–2 months |
| Governing law | CCC | CCC + OCPB |
Market Practice
- Office/retail typically requires 3–6 months' rent
- Factories/warehouses may require 6–12 months depending on property value
- Long-term leases may involve higher deposits
Allowable Deductions
Landlords may deduct from the deposit for:
- Unpaid rent
- Damage beyond normal wear and tear
- Costs of removing tenant fit-outs or modifications (if specified in the lease)
- Unpaid utilities and service charges
Return Timeline
No specific statute governs the return timeline for commercial deposits — it must be specified in the lease. Standard market practice is 30–60 days after lease termination.
Best Practices for Landlords
- Define deposit terms clearly in the lease — Amount, return conditions, timeline
- Prepare a property condition report before and after occupancy
- Specify a deposit return deadline in the contract
- Keep all receipts for repairs and deductions
