If you are a tenant in New Brunswick facing a rent increase you believe is unfair or exceeds provincial rules, there are clear steps you can take to protect your rights. New Brunswick’s laws provide unique protections and a formal process if you wish to challenge a rent hike. This article will walk you through your options, the required forms, and how the process works—using up-to-date government information, all in plain language.

Understanding Rent Increases in New Brunswick

In New Brunswick, landlords can legally increase the rent, but must follow specific notice requirements under the Residential Tenancies Act (New Brunswick)[1]. There is currently no provincial limit (rent control) on how much rent can be increased, but tenants must receive proper notice and have the right to dispute any increase they believe is unreasonable.

  • Landlords must give at least 3 months’ written notice before increasing rent.
  • They cannot increase the rent during a fixed-term lease unless your agreement allows it.
  • For month-to-month or year-to-year leases, increases cannot happen more than once every 12 months.

Knowing your obligations as a tenant is essential. For more about general rights and duties, see Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

How to Dispute a Rent Increase: Step-by-Step

If you feel your rent increase is unfair or not properly served, you can file a formal dispute with the provincial authority. This process can help you negotiate with your landlord, or allow an official to decide if the increase is reasonable.

Step 1: Review the Rent Increase Notice

  • Confirm that your landlord gave you a written notice at least three months in advance.
  • Check for details: the new rent amount, the date the new rent starts, and the method of notice delivery.

Make a note of the notice date and keep a copy of the notice; if the notice is missing details (amount, start date) or isn’t the required length, you can ask for clarification or raise concerns. Gather your lease and any related documents to support your position.

Step 2: Prepare and Submit Form 6 – Application for Assistance “Notice of Rent Increase”

To officially dispute the rent increase, you must file Form 6 – Application for Assistance 'Notice of Rent Increase' to the Office of the Rentalsman (New Brunswick’s residential tenancy board).

Example: Let’s say you get a letter stating rent will increase by $150 in three months. If you feel this is unfair, complete and submit Form 6 within 30 days to start the formal dispute.

Step 3: The Dispute Resolution & Hearing Process

Once you submit Form 6, the Office of the Rentalsman will review your application and may arrange a mediation or a formal hearing. They will notify your landlord and consider factors such as:

  • The history of rent at your unit
  • The comparability to similar rentals in your area
  • The condition of your unit and services provided

You and your landlord may have a chance to present your sides, submit relevant documentation, and suggest a compromise. The Rentalsman’s decision is binding.

Mediation can often resolve issues faster and with less cost than a full hearing; prepare your rent history, lease, and repair records to support your position.

Your Rights and Responsibilities

It’s important to pay the current (pre-increase) rent on time and avoid withholding payment during the dispute unless the Rentalsman orders otherwise. Breaching your responsibilities could impact your case. For a deeper guide on paying rent, see Tenant's Guide to Paying Rent: Rights, Responsibilities, and Tips.

What Happens If You Win or Lose the Dispute?

  • If successful, your rent increase may be reduced, delayed, or cancelled.
  • If not successful, you must pay the new rent as decided by the Rentalsman.

If at any point you have questions about your broader tenant rights in the province, see Tenant Rights and Landlord Rights in New Brunswick.

The Rentalsman’s decision is binding, and there is limited formal recourse if you disagree beyond the dispute process described. You may discuss options with the Rentalsman about enforcement and any possible follow-up steps.
