In New Brunswick, governed by the Landlord and Tenant Act and the Property Act (effective 1 July 1973), the handling of commercial security deposits starkly contrasts with residential rules. While residential deposits are capped at one month's rent and heavily regulated by the government, commercial security deposits operate with significant freedom and rely almost entirely on the terms of the lease agreement.
No Statutory Limits or TLRO Mandates
The most critical distinction for commercial landlords in New Brunswick is the lack of provincial caps or remittance requirements for security deposits.
- No Maximum Cap: There is no law limiting a commercial security deposit to one month's rent. Landlords can demand an amount commensurate with the financial risk of the tenant. Common practice dictates requesting 1 to 3 months of gross rent, but longer terms or riskier startups may require 6 to 12 months.
- No Mandated Deposit Remittance: Unlike residential landlords, who must send all deposits to the Tenant and Landlord Relations Office (TLRO) within 15 days, a commercial landlord can securely hold the funds themselves, often in an interest-bearing trust account, or via an irrevocable letter of credit.
The Importance of Lease Documentation
Because the government does not regulate the parameters of commercial deposits, the commercial lease document must thoroughly outline every interaction with those funds to prevent costly litigation.
A well-drafted commercial lease in New Brunswick should explicitly resolve:
- The Exact Amount: Clearly state the total monetary deposit.
- Form of the Deposit: State if the deposit is cash, a wire transfer, or a Letter of Credit from a bank.
- Interest: Specify whether the deposit will earn interest, and if so, who is entitled to receive that interest (often the landlord retains the interest as an administrative fee, but this is negotiable).
- Conditions for Deductions: List exactly what the landlord can draw upon the deposit for. For example: curing unpaid rent, restoring the premises to "base building" condition after unapproved alterations, covering legal fees associated with a default, or repairing damage beyond normal wear.
- Replenishment Clause: If the landlord draws upon the deposit during the lease term (e.g., to cover a missed rent payment), state that the tenant must replenish the requested funds within a specific timeframe (e.g., 5 to 10 days) upon receiving written notice.
- Return Timeline: State precisely when the balance of the deposit will be returned after the lease expires (e.g., "within 30 days after the tenant surrenders the premises reasonably clean and free of damage").
Using Letters of Credit
For substantial commercial spaces (such as a large warehousing facility or significant retail footprint), New Brunswick landlords frequently require an Irrevocable Standby Letter of Credit rather than a cash deposit.
If the tenant declares bankruptcy, a cash deposit held by the landlord might get tied up in insolvency proceedings. Conversely, a Letter of Credit is a guarantee from the tenant's bank. If the tenant defaults, the landlord can draw against the letter of credit independently of the tenant's bankruptcy protections, providing far superior security for the landlord's cash flow.
Return Procedures and Disputes
Because there is no TLRO equivalent for resolving commercial disputes in New Brunswick, disagreements over security deposit deductions often result in civil litigation or arbitration.
To protect your deductions in a potential dispute:
- Baseline Documentation: Conduct a rigorous initial walk-through. Document the pre-tenancy condition of the premises with extensive photography or video.
- Strict Surrender Guidelines: Ensure the lease clarifies exactly what constitutes a valid "surrender" of the premises (e.g., all trade fixtures removed, floors broom-swept, keys returned).
- Itemized Accounting: Always provide the tenant with an itemized breakdown of any deductions, alongside vendor invoices to prove the repair costs.
