Leases & Agreements New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

Navigating leases and agreements in New Brunswick can feel overwhelming, but it’s crucial for tenants to avoid common mistakes that could affect their housing security. This guide empowers New Brunswick tenants by outlining the most frequent pitfalls, offering practical tips, and providing provincial resources so you can rent safely and confidently.

Understanding Leases and Agreements in New Brunswick

In New Brunswick, leases—also called rental agreements—outline the rights and responsibilities of both tenants and landlords. These documents are legally binding and governed by the province's Residential Tenancies Act[1].

Types of Leases

  • Fixed-term lease: Lasts for a set period (such as 12 months).
  • Month-to-month: Renews automatically unless notice is given.

Always get your lease in writing, and make sure you understand every clause before signing.

Before you sign, request or attach the Standard Form of Lease (RT-FET-0010E) and any addenda; ensure all negotiated terms are included in writing and signed by both parties. Keep a signed copy for your records.

Common Mistakes Tenants Make—and How to Avoid Them

  • Not Reading the Entire Lease: Some tenants skim the agreement, missing critical details on rent increases, maintenance, or renewal terms.
  • Overlooking Rules about Deposits: In New Brunswick, security deposits are strictly regulated—get a receipt and understand the conditions for its return. For more on this, see Understanding Rental Deposits: What Tenants Need to Know.
  • Missing Move-In Inspection: Not documenting the property’s condition at move-in can lead to disputes when moving out.
  • Ignoring Notice Periods: Many tenants forget to provide proper notice before moving out, risking penalties or lost deposits.
  • Assuming Verbal Agreements Are Enough: Always confirm updates or changes to your agreement in writing.

Knowing these pitfalls helps you protect yourself and avoid unnecessary conflict with your landlord.

Key Protections and Responsibilities for Tenants

New Brunswick’s Residential Tenancies Act[1] outlines your rights and responsibilities.

  • Your landlord must use the Standard Form of Lease (RT-FET-0010E).
    Use this government-issued lease for all tenancies. Always fill it in fully, retain a signed copy, and clarify anything unclear with your landlord.
  • Security deposits must not exceed one month’s rent and must be held in trust by the Office of the Rentalsman.
  • Rent increases require three months’ written notice on a month-to-month lease.

If any lease term seems illegal or unfair, contact the Office of the Rentalsman, New Brunswick’s tenancy board, for guidance.

What to Do Before and After Signing

Before Signing the Lease

  • Read every page (including addendums).
  • Inspect the property and take photos.
  • Clarify rules regarding pets, parking, and utilities.

After Signing the Lease

If you’re unsure about a lease term, ask for clarification in writing or seek advice from the Office of the Rentalsman before signing.

Essential Official Forms for Tenants

  • Standard Form of Lease (RT-FET-0010E): Must be used for most rental agreements.
    Example: If your landlord asks you to sign a handwritten lease, request they use the official standard form. View and download the official Standard Form.
  • Notice of Termination by Tenant (RTB-2T): Used if you wish to move out. Give at least one month’s notice (for monthly tenancies).
    How To: Complete the Notice of Termination by Tenant form, sign, date it, and give it to your landlord.
  • Application for Assistance/Complaint (RT-FET-0060E): Submit this if you’re facing an issue your landlord won’t resolve, such as repairs.
    How To: Fill out the Application for Assistance form and file with the Office of the Rentalsman.

All official forms are available on the Office of the Rentalsman’s website.

Tip: Save digital copies of all forms and note deadlines; the Rentalsman can guide you through forms submission and timelines.

FAQ: Lease Agreements in New Brunswick

    Landlords may increase rent, but only after providing three months’ written notice and only once every 12 months, unless agreed otherwise.

    You must provide written notice using the official form. If you break your lease without proper notice, you could lose your security deposit or be responsible for unpaid rent.
