How deposits work in New Brunswick

Security deposits in New Brunswick are held to protect landlords for unpaid rent or damages beyond normal wear and tear. Landlords may not use a deposit for routine repair nor increase rent by keeping funds without following the law. The Residential Tenancies Act sets out when deposits may be applied to arrears and what notice must be given to the tenant.[1] Keep careful receipts and records of payments to show the deposit's purpose.

In most regions, tenants are entitled to basic habitability standards.

When landlords can use deposits for rent arrears

A landlord can only apply a tenant's security deposit to rent arrears when the action is permitted by the Residential Tenancies Act and after following required notice and accounting steps. If a landlord applies a deposit to unpaid rent, they must provide an itemized statement showing the amount deducted and the remaining balance, and tenants can dispute improper deductions with the Residential Tenancies Tribunal.[2] For an overview of what a deposit should cover, see Understanding Rental Deposits: What Tenants Need to Know.

Required notices, timelines and tenant options

  • Pay the outstanding rent within the notice period to avoid deductions from the deposit.
  • Keep receipts and a rent payment record to challenge any improper deductions.
  • File an application with the Residential Tenancies Tribunal to dispute deductions if the landlord does not respond or the matter is unresolved.
  • Attend any scheduled hearing and bring evidence such as photos, messages and bank statements to prove your case.
Respond to legal notices within deadlines to avoid losing rights.

Official forms and how to use them

There are common official forms used in New Brunswick for non-payment and disputes. Landlords typically serve a "Notice to Terminate Tenancy for Non-Payment of Rent" when rent is overdue; this tells the tenant the amount owed and the period to remedy the default before further action may follow.[3] If you disagree with deductions or a termination, you can file an "Application to the Residential Tenancies Tribunal" to start a formal dispute and request a hearing.[2] Example: if a landlord deducts a full deposit for a single late month without an itemized statement, a tenant can file an application and present rent receipts to the Tribunal to ask for a refund.
