How rent increases work in New Brunswick

In New Brunswick, rent increases must follow the rules in the Residential Tenancies Act and related regulations; tenants can bring disputes to the Residential Tenancies Tribunal if they believe an increase is improper [1][2]. Tenants should read any written notice carefully: it should state the new rent amount, the date it takes effect, and be delivered according to the method set out in law. For a clear overview of general tenant and landlord responsibilities in this province, see Tenant Rights and Landlord Rights in New Brunswick.

Keep copies of all rent notices and receipts.

When landlords can propose an increase

  • Landlords must give a written notice that clearly states the increase and the effective date.
  • Notice periods and timing matter; check the required deadline on the notice to avoid missing response windows.
  • Increases affect the monthly rent amount and should be reflected in any new rental agreement or renewal.
  • Tenants should keep records of payments, communications, and any promises about rent to support a dispute if needed.

Official forms you may need

Several official documents are commonly used when a rent increase occurs: the written notice of rent increase, application forms to the tribunal, and any prescribed evidence checklists. Below are typical form names and how tenants use them.

  • Notice of Rent Increase (example name): used by a landlord to inform a tenant of the new amount and effective date; a tenant might keep a dated photo or copy and note when it was received as evidence.
  • Application to the Residential Tenancies Tribunal (application form): used when a tenant disputes an increase; for example, file the application if you believe the increase is retaliatory or not authorized under the Act [3].

How to challenge a rent increase

If you plan to challenge a rent increase, follow clear steps: verify the notice meets legal rules, collect supporting documents (photos, receipts, messages), and file an application with the tribunal before the deadline. Try to communicate clearly with your landlord about errors or misunderstandings first, and keep all exchanges in writing.
