Annual Rent Increase Guideline in New Brunswick Explained

Rent & Deposits New Brunswick published June 13, 2025 Flag of New Brunswick

Understanding how much a landlord can increase your rent is crucial for tenants across Canada. In New Brunswick, the rules for rent increases are set out by provincial law, but they differ significantly from some other provinces. This article gives you a clear guide to the annual rent increase guideline in New Brunswick, your rights, steps landlords must follow, and what to do if you receive a notice of rent increase.

Who Regulates Rent Increases in New Brunswick?

Residential tenancy matters, including rent increases, are overseen by the Residential Tenancies Tribunal of New Brunswick. This is the official body responsible for enforcing the Residential Tenancies Act (RTA).[1]

Is There an Annual Rent Increase Guideline?

Unlike provinces with a pre-set annual rent increase guideline (like Ontario or British Columbia), New Brunswick does not have a fixed percentage limit on rent increases. However, the law states that any rent increase must be reasonable. If you believe your landlord’s proposed increase is unfair, you have the right to challenge it through the tribunal.

The Legal Process: Minimum Notice and Frequency

  • Minimum notice: Landlords must provide at least 3 months written notice before increasing rent for most tenancies.
  • How often: Rent cannot be increased more than once in a 12-month period for the same unit while the same tenant is renting.
  • Notice method: Notice must be delivered in writing—personally, by registered mail, or other acceptable delivery methods.

This notice period and limit on frequency is designed to protect tenants from sudden or multiple increases within a year.

How Do Landlords Notify Tenants of a Rent Increase?

Landlords must give tenants a completed official notice form when increasing rent. In New Brunswick, this is the Notice of Rent Increase (Form 3).

  • Form name: Notice of Rent Increase – Form 3
  • When to use: Landlords are required to serve this form with at least three months' notice.
  • Practical example: If your landlord wants to increase rent starting August 1, you must receive Form 3 by April 30.

Can You Challenge a Rent Increase?

Yes. If you feel a rent increase is unreasonable or the notice wasn't given correctly, you can apply to the Residential Tenancies Tribunal for a review. The Tribunal will consider if the increase is justified based on factors like market rents and the condition of your rental unit.

How Tenants Can Challenge a Rent Increase

  • Fill out the Application for Assistance – Form 6
  • Submit the form to the Residential Tenancies Tribunal within 3 months of receiving the rent increase notice.
  • Be prepared to explain why you believe the increase is excessive (e.g., comparable rents, building condition).
If you receive a rent increase notice that you believe is unfair, act quickly—once the notice period passes, it’s harder to dispute the new rate.

Your Rights and Other Key Considerations

  • You cannot be evicted solely for refusing a rent increase. However, you must pay any lawful rent set after proper notice and process.
  • If your landlord tries to increase rent without giving the proper notice or form, the increase is not enforceable.
  • Always keep a copy of any notice, correspondence, and the signed forms—the Tribunal may request these in a dispute.
