Legal Precedents & Case Summaries New Brunswick 4 min read · published March 09, 2026 Flag of New Brunswick

Tenants in New Brunswick may sometimes be faced with rent increases that exceed the normal standards. Understanding the legal precedents for above-guideline rent increases can help you prepare effectively if you’re involved in a dispute. This article guides tenants through relevant cases, the current rules under provincial law, and practical steps for challenging rent increases effectively.

Understanding Rent Increase Rules in New Brunswick

In New Brunswick, rent increases in existing tenancies are regulated by the Residential Tenancies Act (New Brunswick)1. Landlords can increase rent, but the amount and timing are restricted by law. Since changes in 2022, landlords must give at least three months’ written notice before increasing rent, and tenants have the right to dispute if they believe an increase is unreasonable.

In New Brunswick, rent increases require at least three months' written notice, and you have the right to dispute if the increase seems unreasonable. Gather your current lease, any notices, and cost records to support a dispute, and be ready to file with the Residential Tenancies Tribunal if needed.

Some rent increases might be considered ‘above-guideline’, usually when the landlord claims exceptional expenses (such as major repairs or capital improvements). When this occurs, tenants can file a dispute with the Office of the Residential Tenancies Tribunal of New Brunswick (Residential Tenancies Tribunal).

Above-guideline increases must be supported by specific costs such as repairs or capital improvements; request invoices and cost breakdowns and be prepared to show why the expense qualifies for passing to tenants.

Key Precedents and How Disputes Are Handled

New Brunswick’s tenant-landlord disputes are decided by the Residential Tenancies Tribunal. In recent years, tribunal decisions have clarified several important points regarding above-guideline rent increases:

  • Burden of proof: Landlords must justify why an increase is higher than normal, by showing detailed cost breakdowns or invoices for repairs.
  • Tribunal consideration: The Tribunal reviews if the repairs qualify, their necessity, and whether the cost should be passed to tenants.
  • Tenant right to dispute: Tenants can dispute an increase on grounds that the improvements were not necessary, or costs are excessive.

Although the Tribunal does not publish every decision, summaries highlight the importance of tenants providing clear reasons for disputing and responding quickly to Tribunal notices.

Keep a concise written explanation ready for disputes, and respond quickly to Tribunal notices to avoid missed deadlines.

How to Dispute an Above-Guideline Rent Increase

If you receive a notice of rent increase, and you believe it’s more than what is fair or allowed, you can challenge it. Here is what you need to do:

  • Carefully read the Notice of Rent Increase provided by your landlord.
  • Gather any relevant documentation, such as your current lease and maintenance records.
  • Contact the Tribunal quickly if you wish to object. You have up to 15 days after receiving the notice to file a dispute.

Knowing your rights can give you confidence to challenge increases that seem unfair. For more information about general rent increase rights, see Understanding Rent Increases: What Tenants Need to Know.
