New Brunswick Rent Control Laws Explained for Tenants

Rent & Deposits New Brunswick published June 13, 2025

If you're renting in New Brunswick, understanding your rights around how much your landlord can raise your rent—and when—is essential. New Brunswick has unique rules compared to other provinces, especially because it doesn't have traditional rent control, but does protect tenants from sudden or unreasonable increases. This guide will help you understand how rent changes are regulated, the official processes, and practical steps you can take if you're facing issues.

Who Oversees Tenancy Laws in New Brunswick?

The Residential Tenancies Tribunal of New Brunswick is the official body responsible for handling residential rental disputes, setting out tenant and landlord rights, and ensuring the law is followed.

What Are the Rent Control Rules in New Brunswick?

Unlike provinces with fixed annual rent increase limits, New Brunswick does not regulate the exact percentage a landlord can increase rent by. But, the law under the Residential Tenancies Act (New Brunswick) requires all increases to be reasonable, and gives tenants the right to challenge increases they believe are unfair. This provides some important protections for renters in the province.^[1]

Notice Periods for Rent Increases

Year-to-year or month-to-month leases: Landlords must give at least 3 months' written notice before increasing the rent.
Weekly leases: At least 6 weeks’ written notice is required.

The notice must be given using the official form and must clearly state the amount of the increase and the effective date.

Is There an Official Rent Increase Form?

Form: Notice of Rent Increase (Form 3)
Download the official Form 3: Notice of Rent Increase
When to use: Landlords must use this form to notify tenants of a rent increase. For example, if your landlord wants to raise your rent starting July 1, you must receive this form by April 1 for a month-to-month lease.

If your landlord tries to increase rent without the proper written notice or method, you don't have to pay the higher amount. Keep all paperwork for your records.

Your Right to Dispute a Rent Increase

Tenants can challenge any rent increase they feel is excessive or unfair using the official process through the Residential Tenancies Tribunal. This is an important safeguard for renters concerned about affordability or abrupt changes.

Form: Application to Review a Notice of Rent Increase (Form 4)
Download Form 4: Application to Review Notice of Rent Increase
When to use: Submit this form within 15 days of receiving the Notice of Rent Increase if you believe the amount is unreasonable or did not follow correct procedure.
Practical example: Your landlord raises the rent by $200/month and you feel this is not justified. Fill out Form 4 and send it to the Tribunal before the deadline to have the increase reviewed.

How Rent Increase Reviews Work

Once the Tribunal receives your Form 4 application, they will examine whether the rent increase is reasonable based on market rates, property conditions, and past increases. You and your landlord can submit evidence or comments during the review. Pending the decision, you generally continue paying your previous rent amount unless instructed otherwise by the Tribunal.

If you receive a rent increase you think is unfair, act quickly. Submit your review application within 15 days to protect your rights.

Moving, Renewals, and Your Responsibilities

If rent increases prompt you to consider moving or ending your lease, it's important to notify your landlord correctly. Your rental agreement and rights also affect how these transitions happen.

Tenants must give appropriate notice to end a month-to-month or year-to-year tenancy, typically at least one month's written notice before the end of a rental period.
