Leases & Agreements New Brunswick 3 min read · published March 09, 2026 Flag of New Brunswick

If you rent a home or apartment in New Brunswick, understanding how rent increases affect your lease can help you plan and protect your finances. This guide explains when landlords can raise rent, what written notices must include, how lease renewals and fixed-term agreements differ, and what options tenants have if they believe an increase is unfair. You will also find practical steps for documenting communications, filing a complaint with the provincial tenancy tribunal, and examples of forms you may need. The language is plain and focused on tenants rights and responsibilities so you can act confidently whether negotiating with your landlord or preparing to contest an increase.

How rent increases are regulated

In New Brunswick, rent increases are governed by provincial tenancy rules and the Residential Tenancies Act. Landlords must follow the Acts requirements for notice, timing, and any caps or exemptions that apply. Many disputes are resolved through the provincial tribunal that handles tenancy matters, the Residential Tenancies Tribunal[1], which explains procedures for challenging an increase and timelines for hearings.

Tenants often have legal protections about how and when rent can be raised.

What notice must include and timing rules

Before raising rent, a landlord must give proper written notice describing the new amount and the date it takes effect. For tenants on a fixed-term lease, increases usually cannot take effect until the lease ends unless your lease specifically allows an earlier change. For month-to-month tenancies, the Act sets minimum notice periods and timing requirements.

  • Check that any rent increase notice is in writing and dated.
  • Confirm the effective date and whether it respects minimum notice periods.
  • Keep a copy of the notice and any delivery proof for your records.
Save photos or a scanned copy of any notice and the envelope postmark or email timestamp.

When you can challenge an increase

If you believe a rent increase is improper, you can ask the landlord for an explanation, try to negotiate, or file an application with the Residential Tenancies Tribunal[1]. Common grounds to challenge include failure to follow notice rules, increases that violate provincial limits, or increases tied to illegal discrimination or retaliation.

Documenting conversations and keeping dated records strengthens your position in disputes.

Forms tenants may need

Tenants and landlords often use official forms when giving notice, applying to the tribunal, or responding to an application. Typical forms include the Notice to Increase Rent and the Application to the Residential Tenancies Tribunal. For example, a tenant disputing a notice would complete the tribunals application form, attach the written rent increase notice, and submit it according to tribunal instructions.[3]

Practical steps for tenants

Follow these steps to respond to a rent increase you think is incorrect or unfair.

  1. Read the written notice carefully and compare dates to your lease and provincial rules.
  2. Ask the landlord in writing for clarification if anything is unclear, and keep a copy of your message.
  3. Gather evidence: a copy of your lease, photos, rent receipts, and the increase notice.
  4. Contact tenant help services or the tribunal for advice on deadlines and next steps.
  5. File an application with the Residential Tenancies Tribunal if you cannot resolve the issue and believe the increase is not permitted.[1]

Common tenant questions

Can my landlord increase rent during a fixed-term lease?
Generally no, unless the lease explicitly allows an increase or you both agree in writing; increases most often apply at renewal or after the fixed term ends.
How much notice must I get before a rent increase?
Notice periods are set by provincial rules and the Residential Tenancies Act; check the tribunals guidance for exact timelines and whether special rules apply to your situation.
What if the rent increase seems retaliatory?
Retaliatory increases are often prohibited; document the events and consider applying to the tribunal to challenge the increase.
