Tenant Challenge to Rent Increase in New Brunswick: What Landlords Should Expect

The 60-Day Review Window

After receiving a standard rent increase notice, a tenant in New Brunswick has 60 days to submit an Application for Assistance to the Tenant and Landlord Relations Office (TLRO). A mobile home site tenant has 15 days under Section 25.4(3). There's no filing fee for the tenant application.

The tenant doesn't need to prove the increase is illegal to file — the application triggers a formal review regardless. The officer then investigates and decides.

For landlords, the 60-day window is the period of exposure. After it closes without an application, the increase proceeds as served. During it, you should have your documentation ready.

Grounds a Tenant Can Raise

The Act allows tenants to challenge a rent increase on several grounds:

Separate document failure. The notice was combined with a lease renewal, receipt, or other correspondence, violating Section 11.1(2)(b). This is the most effective ground — if proven, the officer must set aside the notice.

Default 12-month frequency limit. For a tenancy governed by Section 11.1, the increase falls in the first consecutive 12-month period or is more than one in another such period, and the parties did not agree otherwise in writing.

Insufficient notice period. The tenant received less than six full calendar months' notice before the effective date.

Over-cap without approval. The proposed increase exceeds 3.0% and the landlord hasn't obtained prior written authorization from an officer.

Retaliatory increase. Under Section 11.2(1), a notice served between the day the tenant makes a complaint and six months after that day is not valid if the tenant tells an officer in writing within 15 days after receiving the notice that they believe it was retaliatory and the landlord does not satisfy the officer that it was not served for that reason.

What the Officer Can Do

A Residential Tenancies Officer has three main powers when reviewing a challenged increase:

Set aside the notice entirely. If the landlord can't prove the notice was served as a separate document, the officer must set it aside under Section 11.1(2.04). This voids the increase completely — the landlord starts over with a fresh notice and a new six-month clock.

Deemed 3% increase. Under Section 11.12(2), a notice proposing more than 3% without approval is deemed to be a 3% notice. This statutory effect does not depend on an officer reducing the amount.

Order reimbursement. If the tenant has already started paying the increased amount and the increase is found unlawful, the officer can order the landlord to reimburse the overpayment or credit it against future rent.

How Landlords Should Prepare

The moment you serve a rent increase notice, assume it might be reviewed. Build your evidence file before service, not after:

Proof the notice was separate. Keep a copy of the notice on its own, with nothing else on the page. If you delivered it alongside other documents, note that each was a separate physical document.

Proof of service. Keep a record of the personal delivery, ordinary-mail date, or electronic transmission to the address given in the lease. The Act deems mail served on the third day after mailing and electronic transmission served on the date sent. The burden of proving service falls on you.

12-month calculation. Document the tenancy agreement's commencement date and any prior rent increase dates. Show whether the default frequency limit in Section 11.1(2.01) applies or the parties agreed otherwise in writing.

Rent calculation. Show the current rent, the percentage increase, and the new rent. If it's a standard increase, the math should show 3% or less. If above-cap, attach the officer's approval letter.

The Officer Investigation

When an application comes in, the officer reviews both sides. Expect to be contacted and asked to provide your documentation. The investigation is administrative, not adversarial — there's no courtroom hearing. The officer examines the evidence, applies the statutory rules, and issues a decision.

Decisions are binding. If you disagree, the only appeal is to the Court of King's Bench under Section 27(1), filed within seven days of the decision. Appeals are limited to questions of law or jurisdiction — the court won't re-examine the facts.

What the Tenant Can Do Instead of Challenging

A tenant who receives a lawful increase notice has three options:

1. Accept and pay the new rent on the effective date
2. Challenge within 60 days via the TLRO for a standard tenancy, or within 15 days for a mobile home site tenancy
3. Terminate the tenancy by giving at least one full month's written notice before the effective date (one full week for week-to-week tenancies)

Termination ends the tenancy on the day before the increase takes effect. This is a right the tenant holds regardless of whether the increase is valid.
