Notice Periods and Rules for Rent Increases in New Brunswick

Affordable Housing & Subsidies New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

If you’re renting in New Brunswick and your landlord wants to raise the rent, it’s important to know your rights and understand the official notice requirements. The law in New Brunswick sets out clear rules that protect both tenants and landlords, providing time to prepare or respond before any rent increase takes effect. Here’s what tenants need to know about notice periods, legal limits, and how to take action if you have concerns.

Who Sets the Rules? The Official Tribunal and Legislation

Residential tenancies in New Brunswick are overseen by the Residential Tenancies Tribunal. The main law is the Residential Tenancies Act (New Brunswick).[1]

How Much Notice Does My Landlord Have to Give for a Rent Hike?

In New Brunswick, landlords must give at least three months’ written notice before increasing the rent. This applies to month-to-month, week-to-week, and year-to-year tenancies, unless you have a fixed-term lease that says otherwise. The notice must include:

Keep a dated copy of the notice and note how it was delivered (hand-delivered, mailbox, or registered mail). If any required detail is missing (the new rent amount, the start date, or three months’ notice), it may be subject to challenge at the Tribunal.
  • The amount of the new rent
  • The date the new rent starts
  • The signature of the landlord or their agent

The notice period gives you, as a tenant, time to plan, budget, or object if necessary. You cannot be forced to pay the higher rent until the full three months’ notice has passed.

Does New Brunswick Limit How Much the Rent Can Go Up?

There is no legislated cap or maximum percentage for rent increases in New Brunswick. However, increases must be reasonable and not intended to force tenants out unfairly. If a tenant feels the increase is excessive, you may apply for a review with the Residential Tenancies Tribunal.

Even without a cap, increases must be in good faith and not aimed at pushing you out. If you think an increase is excessive for your area, gather local rent comparisons and contact the Residential Tenancies Tribunal for guidance before the increase takes effect.

What Does a Legal Rent Increase Notice Look Like?

There’s no official government form required, but the written notice must be clear, state the effective date, and be delivered properly. Notices can be hand-delivered, left in your mailbox, or sent by registered mail.

If you receive a rent increase notice, check that it includes the new rent amount, the start date, and has been given with at least three months’ notice. If it misses any of these, it may not be valid.

What If I Think the Rent Increase Is Unfair?

You have the right to challenge a rent increase if you believe it’s unreasonable, especially if the hike seems intended to pressure you to leave or is vastly higher than typical market increases. File an application with the Residential Tenancies Tribunal for a review.

Common misstep: assume fairness without evidence. Gather market rent comparisons for your unit, keep copies of the notice, and review any lease terms; then file RT Form 9 if you need Tribunal review.

Relevant Form: Request for Assistance (RT Form 9)

  • Form Name and Number: Request for Assistance (RT Form 9)
  • When and How to Use: Use this form to ask the Tribunal to review a rent increase or help resolve a dispute about the notice you received. For example, if your landlord gives you a notice with less than three months or raises your rent by a very large amount, complete RT Form 9.

Important Timing and Renewal Rules

Landlords can only increase your rent once every 12 months for the same unit. Tenants continuing under the same agreement after a 12-month period can be served notice again, but only with three months’ advance notice each time. If you’re signing a new fixed-term agreement, review your contract to see if any increase is already set out for the next term.

Tip: When renewing, check if your fixed-term has any built-in increases and note the renewal date to avoid surprises; always confirm the next terms in writing.

What to Do After Receiving a Rent Increase Notice

  • Verify the notice is properly written and delivered at least three months in advance.
  • Check if the amount or frequency of rent increases seems fair or complies with the law.
  • Ask your landlord questions if anything is unclear.
  • If disputing, file the Request for Assistance (RT Form 9) promptly to the Residential Tenancies Tribunal.

Your Rights and Responsibilities

Tenants must continue to pay the current rent until the new amount is legally due. As always, ensure your rent is paid on time and in full. Read Tenant's Guide to Paying Rent: Rights, Responsibilities, and Tips for more on your obligations.
