The guidance is aimed at renters and first-time tenants who want to protect their rights, understand timelines, and avoid surprises while negotiating or renewing a lease in New Brunswick.

How rent increases apply to new rental builds in New Brunswick

New units sometimes have different considerations than older units, especially during initial leasing or when buildings convert to market rents. In New Brunswick, rent increases and exemptions are governed by provincial legislation and decided by the Residential Tenancies Tribunal; always check the Act and Tribunal guidance for the most up-to-date rules.[1] If a landlord plans a rent increase for a recently built unit, they must follow the notice and filing requirements set out by the province and by Tribunal forms where applicable.[2]

Keep written records of every rent notice and any conversations about rent increases.

Key points tenants should know

  • Landlords must give written notice before any rent increase; check the Tribunal for required timelines and form guidance.[2]
  • Some new-build units may be exempt from provincial rent control or different caps in their first months—confirm whether an exemption applies under the legislation.[1]
  • Document your lease, receipts and any communications; photos and copies help if you file an application with the Tribunal.
  • If you have questions, contact the Tribunal office or an official tenant support line listed below before signing or accepting an increase.

If you receive a rent increase notice you think is improper, it is usually best to respond in writing, keep a copy of the notice, and ask the landlord to explain in writing why the increase is lawful. You can often resolve issues informally, but if not, the Residential Tenancies Tribunal accepts applications to decide whether the increase follows the Act and applicable rules.[2]

Respond to rent increase notices promptly to preserve deadlines for Tribunal applications.

Practical actions to take

  • Read your lease for any clauses about initial rent-setting or increases when moving into a newly built unit.
  • Ask the landlord for written notice explaining the increase and the effective date; keep a dated copy.
  • Compare the new rent to similar units in your area to assess reasonableness before escalating.
  • Contact official tenant advice services if you need help interpreting the notice or finding the right Tribunal form.
