Evictions New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

Protecting your safety and privacy is crucial when renting in New Brunswick. Many tenants wonder if they’re allowed to change the locks on their unit—especially if they're worried about unauthorized entry or dealing with eviction or relationship changes within the household. Understanding your rights under New Brunswick law will help you make informed decisions while staying compliant with your lease and provincial regulations.

In New Brunswick, the law requires mutual consent to change locks. Always document any agreement and keep copies of relevant lease clauses about lock changes.

Tenant and Landlord Rights Around Changing Locks in New Brunswick

In New Brunswick, the rules for changing locks are clear. Under the Residential Tenancies Act of New Brunswick, neither the landlord nor the tenant can change the locks on a rental premises without the consent of the other party. This rule promotes safety while ensuring that both parties have reasonable access as outlined in their lease.[1]

  • If you’re a tenant and change the locks without written permission from the landlord, you may be in breach of your lease.
  • A landlord is also prohibited from changing locks to prevent a tenant’s lawful entry—doing so could result in fines or tribunal action.
  • If locks are changed (with mutual consent), both parties must receive a key immediately.

Consent: A Must-Have for Any Lock Change

Consent should always be documented. The safest way is to use written communication (such as email or a signed letter) and keep copies for your records. If your lease contains specific language about locks or allows changes, follow what’s outlined, but make sure to keep your landlord in the loop.

If you feel unsafe or have immediate security concerns, discuss these with your landlord as soon as possible. Mutual agreement often leads to quick solutions and helps protect your rights and property.

What If the Landlord Refuses Permission?

If you believe there’s a valid reason to change the locks (such as lost keys, domestic violence, or a break-in), but your landlord refuses, you can apply for a resolution with the Residential Tenancies Tribunal of New Brunswick.[2] They handle issues related to tenancy, including lock disputes.

If you apply to the Tribunal, be prepared to explain your safety concerns and include supporting documents such as key dates, messages with your landlord, and any police or emergency reports.

Filing a Complaint with the Residential Tenancies Tribunal

If permission is not granted and you feel your safety is at risk, you can submit a Tenant Application Form to the Tribunal. Here’s how:

  • Form Name: Tenant Application Form (Form 6B)
  • When to Use: Use this form to request an order for a lock change or to resolve disputes about landlord access or unsafe situations.
  • How to Access: Download the Tenant Application Form directly from Service New Brunswick.

Complete the form and submit it to the Tribunal, explaining your situation clearly. The Tribunal will review and may contact your landlord for further input.

Before submitting, make copies of the form and gather supporting documents such as timelines, incident notes, and any correspondence with your landlord.

Requirements and Exceptions

  • Changing locks without consent can lead to eviction proceedings or legal actions.
  • If you are evicted, your landlord may change the locks—but only after the eviction order is final and only after giving you the chance to collect your belongings.
  • Special exceptions may apply if your safety is threatened—document all incidents and seek immediate help from local authorities when needed.
