Avoiding Roommate Mistakes in New Brunswick Rentals

Roommates & Shared Housing New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

Living with roommates or sharing housing in New Brunswick can be affordable and rewarding, but it also comes with unique challenges and legal considerations. If you’re a tenant in shared accommodation, understanding your rights and the common pitfalls can help you enjoy a safer, more harmonious living situation. This guide covers practical steps, legal requirements, and expert tips for avoiding common mistakes with roommates and shared housing in New Brunswick, including what to do if problems arise.

Types of Shared Housing Arrangements

Shared housing in New Brunswick usually falls under one of two main types:

  • Co-tenancy (Joint Lease): All roommates sign the same lease. Each tenant is legally responsible for the entire rent and all lease obligations.
  • Individual leases or sublets: Each person may have a separate agreement with the landlord or with another tenant (the “head tenant”).

Knowing your specific arrangement affects your rights and responsibilities, especially when moving in, splitting rent, or ending the tenancy.

Key Legal Protections for Tenants Sharing Housing

In New Brunswick, residential tenancies are governed by the Residential Tenancies Act.[1] The Residential Tenancies Tribunal oversees tenant and landlord issues, including shared accommodation disputes.

As a roommate, your rights can depend on your legal relationship with the landlord, so always clarify if you’re a tenant or a subtenant. If you signed the lease, you’re directly protected by tenancy law—and responsible for your share of the obligations.

Common Mistakes Tenants Make with Roommates

  • Not having a roommate agreement: Without a written agreement, it’s easy for disagreements over chores, expenses, or guests to escalate.
  • Assuming the landlord will mediate roommate disputes: The landlord is not responsible for resolving conflicts between roommates unless it involves the property or the lease.
  • Poor communication around bills or repairs: Not delegating responsibilities for rent payments or maintenance can cause serious disputes if one tenant falls behind.
  • Failing to document damages: Disagreements often arise about who caused damages and who pays for repairs. Always take photos and complete inspections when moving in and out.

Roommate Agreements: Why They Matter in New Brunswick

Roommate agreements help set clear guidelines around:

  • Splitting rent and utility costs
  • Cleaning duties and shared responsibilities
  • Guest and pet policies
  • How to handle a roommate moving out early

While not legally binding under the Residential Tenancies Act, a roommate agreement can help prevent and resolve disputes among tenants.

Tip: Write your roommate agreement down and have everyone sign it. This provides clarity and helps avoid future misunderstandings.

Deposits, Rent, and Shared Responsibility

Most landlords in New Brunswick require a security deposit for a new tenancy. All co-tenants are usually equally responsible for the deposit and rent. If one roommate leaves early, the others may be responsible for covering their share until a replacement is found or the tenancy legally ends.

Dealing with Roommate Conflicts and Maintenance Issues

Disputes in shared housing often relate to cleanliness, noise, property damage, or missed rent payments. Here’s what to do:

  • Talk openly and document communications
  • Refer to your roommate agreement
  • For serious repair or health risks, contact the landlord in writing
  • If the landlord is also your roommate, you remain protected by tenancy legislation

Moving Out or Changing Roommates

Unexpected departures, personality conflicts, or changes in job or school can mean someone needs to move out. In a joint lease, tenants typically remain liable unless everyone, including the landlord, agrees to remove or replace a roommate. When moving out, consult: Tenant Rights and Landlord Rights in New Brunswick for guidance on proper notice and ending your tenancy.

Required Forms and Legal Processes

  • Notice to Quit (Form 3): Used to give written notice when ending your tenancy. You must submit this to the landlord and other co-tenants.
    Find the official form and instructions on the Service New Brunswick Tenancy Forms page.
  • Application to the Residential Tenancies Tribunal (Form 6): If you and your roommates can’t resolve disputes, you may apply for conflict resolution. Learn how to submit this application on the Residential Tenancies Tribunal website.
    For example, use Form 6 if you dispute responsibility for damages or if a co-tenant won’t cooperate when moving out.

Always keep copies of all completed forms and communications.

Keep copies of all forms and communications, and track filing deadlines for the Tribunal or landlord responses. Missing deadlines can affect your rights, so set reminders and save emails or messages.

What to Do Before Moving In Together

This preparation is key to preventing disputes later on. For more options, you can Explore Houseme for nationwide rental listings.

Example: Before moving in, draft a one-page roommate agreement, have everyone sign, and take dated photos of the unit and a move-in checklist to share with the landlord.

FAQ

  1. Can my landlord evict all roommates if one person breaks the lease?
    In a joint tenancy, if the group is found in breach (e.g., unpaid rent), the landlord may take action against all tenants. Try to resolve the issue within your group before it escalates.
  2. Does New Brunswick tenancy law cover disputes between roommates?
    No—tenancy law generally governs landlord-tenant issues, not those between roommates. Roommates must resolve personal conflicts themselves unless the landlord or tenancy agreement is involved.
  3. How can we change a roommate on the lease?
    Request the landlord’s written consent. All parties—including the new roommate—may need to sign an updated lease.
  4. Is a roommate agreement enforceable by law?
    Roommate agreements are not generally enforceable by the Residential Tenancies Tribunal but can be useful evidence in private disputes.
  5. Who gets the damage deposit back at the end of the tenancy?
    The deposit is typically returned to all tenants listed on the original lease. It’s up to the group to divide it if someone left early.

How To Handle Roommate Problems in Shared Housing

  1. How do I give official notice if I want to move out?
    Complete the Notice to Quit (Form 3), provide the required notice period, and serve it to your landlord and co-tenants.
  2. How can I recover unpaid rent from a roommate?
    If your co-tenant owes you money, document communications and, if unresolved, consider small claims court for disputes not covered by the Tribunal.
  3. What steps should I take if my roommate damages the unit?
    Take photos, notify your landlord, and clarify responsibility using your roommate agreement. The group may be jointly responsible if the lease is shared.

Key Takeaways for Tenants in Shared Housing

  • Understand your legal relationship to the landlord—joint lease or sublet arrangements have different rights and responsibilities.
  • Put agreements with roommates in writing to prevent misunderstandings.
  • Use official forms and processes when moving out or resolving disputes.
