If you are a tenant in New Brunswick, you might be wondering whether your landlord can legally require a key deposit when you move into a rental unit. Understanding your rights around deposits is important for a smooth renting experience and to protect your finances. This article explains key deposit rules in New Brunswick, the relevant law, and what you should do if you're asked for any type of deposit beyond what's allowed.

Key deposits are not allowed in New Brunswick. If a landlord asks for one, document the request, keep receipts, and contact the Office of the Rentalsman for guidance on next steps.

Key Deposits in New Brunswick: What the Law Says

In New Brunswick, landlords are not permitted to ask for a key deposit in addition to the security deposit. The Residential Tenancies Act of New Brunswick outlines what types of deposits are legal and caps the total amount landlords can collect at the start of a tenancy.

  • Only one deposit is allowed: Landlords may collect a security deposit before you move in, up to one week’s rent.
  • Key deposits are NOT a separate legal charge: Requiring a key deposit on top of your allowed security deposit is not permitted under New Brunswick legislation.
  • If a landlord includes a key deposit as part of your regular security deposit (not exceeding the one-week cap), it may be allowed but must be returned at the end of your tenancy if no keys are lost.

How Security Deposits Work in New Brunswick

Your landlord can request a security deposit when you sign the lease, but the law is clear: the deposit, including any amount for keys, cannot be more than the equivalent of one week’s rent. This deposit must be placed with the Office of the Rentalsman, who holds it until the end of your tenancy.

  • If you return all your keys and there is no damage beyond normal wear and tear, you should receive your full deposit back after the tenancy ends.
  • If you lose a key, a fee for replacement may be deducted from your deposit when you move out.
Remember: Any deposit (key, security, or otherwise) must not exceed the maximum amount legally allowed, and your landlord can't demand additional separate fees for keys.

Forms and Processes: What Tenants Should Expect

At the start of your tenancy, your landlord should provide a written notice or use the official Security Deposit Form (Form 2), required under New Brunswick law. Here’s how it works:

  • Form 2 – Security Deposit: This form acknowledges the amount of your deposit and that it has been paid to the Office of the Rentalsman. This protects both tenant and landlord.
    Find Form 2 and guidance from the Office of the Rentalsman.

When you move out, request your deposit back through the Office of the Rentalsman if there are no outstanding issues. Having a clear move-in and move-out process also helps. For more moving tips, see Essential Tips for Tenants When Moving Into a New Rental Home.

What If You Paid an Illegal Key Deposit?

If a landlord collects more than the maximum allowed deposit, or charges a separate key deposit improperly, you can file a complaint with the Office of the Rentalsman (the government body handling residential tenancies in New Brunswick). File a Tenant Application for Assistance (Form 3) to dispute improper deposits. Get Form 3 and instructions directly from the government website.

Always get a receipt for any deposit you pay and confirm it was properly filed with the Office of the Rentalsman.
