Rent & Deposits New Brunswick 3 min read · published March 09, 2026 Flag of New Brunswick

As a tenant in New Brunswick, understanding your rights concerning rent increases is crucial to managing your housing expenses effectively. In this province, the rules around how and when rent can be increased are specified under local legislation, ensuring that tenants are treated fairly and with advance notice.

Understanding the Legal Framework

In New Brunswick, rent increases are governed by the Residential Tenancies Act1. This legislation outlines the rights and responsibilities of both landlords and tenants when it comes to changing the cost of rent.

Notice of Rent Increase

Your landlord must provide written notice if they intend to increase the rent. The notice must be given at least three months before the increase takes effect, giving you sufficient time to plan financially.

Limitations on Rent Increases

Unlike some other provinces, New Brunswick does not impose a cap on how much rent can be increased; however, it does require that increases must be reasonable and justifiable. Regular market rates, maintenance costs, and other variables often determine these increases.

No cap exists, but increases must be reasonable. Compare the proposed increase to local market rents and documented costs. If the landlord can't justify it with receipts or estimates, seek mediation or a tribunal review.

Steps for Tenants to Manage Rent Increases

  • Review the Notice: Ensure the notice period is adhered to as per legal requirements.
    Keep a dated copy of the notice and verify it states the amount, the exact increase, and the effective date; if the three-month rule isn't followed, you may challenge the increase at the tribunal.
  • Consult the Landlord: Open communication about the increase might provide clarification or negotiation possibilities.
  • Seek Mediation: If negotiations with your landlord do not resolve your concerns, consider contacting the Residential Tenancies Tribunal for mediation options.
If you feel that a rent increase is unjustified, consider reaching out to the Residential Tenancies Tribunal for assistance and mediation services.
