Rent Deposits and Security Deposits in New Brunswick: Tenant Rules

Maintenance & Repairs New Brunswick 4 min read · published March 09, 2026 Flag of New Brunswick

If you're renting in New Brunswick, understanding the differences between security deposits and rent deposits is essential. This guide helps tenants know what deposits landlords can legally request, how those funds are handled, and how to protect your rights under New Brunswick's rental laws.

In NB, landlords may request only a security deposit, not a rent deposit. The security deposit must be held by the Office of Rentalsman and documented with an official receipt.

What Is a Security Deposit in New Brunswick?

In New Brunswick, a security deposit is money paid to the landlord, held as security against potential damages or unpaid rent during your tenancy. It is regulated by the Residential Tenancies Act (New Brunswick)[1] and overseen by the Office of Rentalsman, New Brunswick's official tenancy authority (learn more here).

  • Maximum amount: Landlords can only request up to one week's rent for a week-to-week tenancy or one month's rent for a month-to-month or longer lease.
  • How it’s handled: Landlords must deposit your security deposit with the Office of Rentalsman, not keep it personally.
The security deposit covers things like unpaid rent or damages beyond normal wear and tear. It cannot be used for routine repairs or maintenance.

Are Rent Deposits Allowed?

Unlike security deposits, rent deposits are not permitted in New Brunswick. Landlords cannot require you to pay last month's rent, post-dated cheques, or "hold" deposits as a condition for renting. Only a security deposit may be collected, following the regulations above.

Rent deposits are not permitted in New Brunswick. If a landlord asks for one, refuse and contact the Office of Rentalsman for guidance on compliant deposits.

How Security Deposits Work: From Payment to Return

When you provide your security deposit, your landlord must:

  • Use the official Form 2: Security Deposit – Receipt (download here)
  • Submit the deposit to the Office of Rentalsman within 15 days of receipt
  • Provide you with a receipt and proof of registration

When you move out, you can request your deposit back, including any interest accrued.

Getting Your Deposit Back

At the end of your tenancy, you should:

  • Request return of your deposit using Form 3: Security Deposit – Tenant Request for Refund (access here)
  • Complete a move-out inspection with your landlord if possible
  • Ensure you have provided a forwarding address for deposit return

If there is a dispute—such as the landlord claiming damages—the Rentalsman will review and determine what portion of the deposit, if any, should be returned to you.

Steps to reclaim your deposit: use Form 3, provide a forwarding address, and organize a move-out inspection; keep any receipts and notes. If the landlord withholds funds, contact Rentalsman for guidance.

Your Rights and Protections

New Brunswick's tenancy law provides several protections for deposits:

  • Landlords may only request security deposits – not rent deposits, pet deposits, or other fees.
  • Security deposits must be held by the Office of Rentalsman, not the landlord.
  • You are entitled to interest on your deposit, calculated and paid to you when returned.
  • Any deduction (for example, property damage) must be explained and proven by the landlord.

Steps If You Experience Issues

If your landlord asks for an illegal deposit or refuses to return your deposit, you can:

  • Remind them only security deposits are permitted under NB law
  • Document all communication and keep receipts
  • Contact the Office of Rentalsman for guidance or to file a complaint
