Rent & Deposits New Brunswick 4 min read · published March 09, 2026 Flag of New Brunswick

Rent increases can be stressful for renters in New Brunswick. This guide explains how provincial rules work, what written notice your landlord must give, timelines you should expect, and the forms and tribunal steps you can use if you disagree. It covers how to check whether an increase follows the Residential Tenancies rules, how to preserve documents such as receipts and emails, and practical steps to respond or apply for a hearing. If you are on a fixed-term lease, a month-to-month agreement, or facing a rent bump because of renovations or utilities, this information helps you understand your rights and options as a tenant in New Brunswick.

How rent increases work in New Brunswick

Rent increases must be given in writing and should follow the province's Residential Tenancies rules. Tenants commonly see increases at the end of a lease term or on a month-to-month tenancy; if you have a fixed-term lease, increases normally cannot take effect until the lease ends unless the agreement says otherwise. If you believe a notice is incorrect or not valid under provincial law, you can gather evidence and ask the Residential Tenancies Tribunal to review it.[1]

Keep all rent receipts and written communications in one place.

Key points to check

  • Whether the landlord gave a clear written notice of the increase and how it was delivered.
  • The timing of the notice compared with your rental period or lease end date.
  • Whether the amount matches what the landlord stated and any promised increases for renovations or utilities.
  • What evidence you have: receipts, emails, photos, or old rent receipts showing past amounts.
Respond to rent increase notices in writing as soon as possible to protect your rights.

Notices, forms and official steps

When a landlord increases rent they should use the appropriate written notice or form identified by the provincial tenancy program. If you disagree with the increase, you can file an application with the Residential Tenancies Tribunal to request a review or hearing. Typical official documents include a notice of rent increase and an application form for tenancy disputes; see the provincial forms page for the exact PDF and filing instructions.[3]

Common forms and how tenants use them

  • Notice of Rent Increase (name varies): used by the landlord to tell you in writing about the new rent and the date it takes effect; keep a dated copy and any delivery receipt.
  • Application to the Residential Tenancies Tribunal (hearing request): used by a tenant to dispute an increase; include copies of receipts, the notice, and a short timeline of events for the tribunal.
Bringing clear, dated evidence to a hearing improves your chances of a quick resolution.

How to respond if you get a rent increase notice

Start by confirming whether your tenancy is month-to-month or fixed-term and check the notice date against your rental period and lease. If you decide to challenge the increase, send a written reply to the landlord explaining why you disagree and ask for supporting documents. If that does not resolve the issue, file the tribunal application and bring copies of all communications and proof of past rent payments to any hearing.

FAQ

How much notice must my landlord give for a rent increase?
Landlords must provide written notice in accordance with provincial rules; check the official Residential Tenancies guidance and the increase notice itself for required timing.[2]
Can my rent be increased during a fixed-term lease?
Normally a fixed-term lease locks in the rent amount until the lease expires unless the signed agreement specifically allows increases; review your lease and get advice if unsure.
What if I miss a tribunal deadline?
Missing a filing or response deadline can affect your options; act quickly, keep copies of everything, and check the tribunal's rules for requests to extend or accept late filings.

How-To

  1. Read the written notice carefully and note the date the increase is supposed to start.
  2. Collect evidence: past rent receipts, the lease, messages from your landlord, and any photos or invoices related to claimed renovations.
  3. Speak to your landlord in writing to ask for clarification or negotiate a different date or amount, and save the reply.
  4. If you can’t resolve it, file an application with the Residential Tenancies Tribunal and attach your documents.[1]
  5. Attend the hearing, present your organized evidence, and follow tribunal directions; bring originals and copies.
