5 Essential Things to Know About Roommates in New Brunswick

Roommates & Shared Housing New Brunswick 6 min read · published March 09, 2026 Flag of New Brunswick

Living with roommates or in shared accommodation is common in New Brunswick. Whether you're splitting costs in a two-bedroom apartment or living in a rooming house, understanding your rights and responsibilities helps you avoid conflicts, protect your deposit, and enjoy a safe home environment. Here are five key points every tenant should know about having roommates or living in shared housing in New Brunswick.

If all tenants are named on the lease, you’re jointly liable for rent and damages. Ask for a written list of everyone’s names on the lease and keep that document with your other rental papers.

1. Who Is Legally Responsible: Joint vs. Individual Tenancy

When renting with others, it's crucial to know whether you're all on one lease or have separate rental agreements. If everyone signs the same lease, you're usually jointly responsible for rent and damages. This means the landlord can ask any one tenant for the full rent if others don't pay.

If you’re only a roommate not named on the lease, you may have fewer rights or protections. Ask the landlord for a copy of the lease or write an addendum that names you and your rights.
  • If you're just a roommate (not named on the lease), you may have fewer rights or protections.
  • Changes in household (roommates leaving) may require landlord approval.

Always ask for a written agreement and clarify with your landlord who is recognized as a tenant. For a full overview, see the Residential Tenancies Act and confirm in writing who is listed as a tenant.

2. Deposits and Payment Rules for Shared Units

Security deposits in New Brunswick are governed by provincial law. Each tenant is typically individually responsible for their part of the deposit, but this can change if your names are all on the same agreement.

Keep receipts for your share of the deposit and document payments. Take photos of the unit when moving in and out to help resolve any later disputes.
  • The total deposit cannot exceed one month's rent for the entire unit.
  • Keep records of your payments—this protects you if a roommate moves out early.
  • Ask for a receipt when paying your share.

3. Division of Responsibilities: Rent, Repairs, and Cleaning

Splitting costs and keeping shared spaces tidy is a major roommate challenge. Clarify early how you'll share rent, utility bills, and cleaning duties. Some useful best practices include:

A written roommate agreement helps prevent disputes about chores and bill payment; document any changes if roommates move in or out.
  • Have a written roommate agreement for household chores and bill payment responsibilities.
  • Agree who will contact the landlord if something breaks.
  • Know that each legal tenant is responsible for meeting all obligations under the lease and law.

4. Health, Safety, and Dispute Resolution in Shared Housing

Everyone in shared housing deserves a safe, healthy home. Issues such as mold, broken appliances, heating, or even pests can be common—especially with several people sharing one space.

Document health concerns in writing and keep copies of correspondence with both landlord and roommates to build a clear timeline if disputes arise.
  • Report health and safety concerns to your landlord as soon as they arise.
  • Keep copies of communication with your roommates and landlord to track concerns and responses.
  • If disputes arise, try to resolve them calmly, in writing when possible, before escalating.

Tip: Always keep copies of any forms and correspondence you submit. Seek help from the Rentalsman for complex disputes or questions about shared leases.

5. Ending Your Part of a Shared Lease: Notices and Moving Out

If you or your roommate want to move out early, laws around notice and subletting apply. In New Brunswick, ending a lease usually requires all tenants’ agreement if everyone is on one contract. If you have a separate agreement, you may be able to give notice on your own.

If you’re on a joint lease, ending your portion may require coordination with others and could affect their deposits or the lease. Check your lease terms and discuss notice with the landlord before moving out.
  • Give proper written notice to the landlord and follow the terms in your lease.
  • If disputes over deposits or damages arise, contact the Rentalsman—the provincial authority for tenant-landlord disputes.

  1. What should I do if my roommate stops paying rent?
    If you both signed the same lease, you're still responsible for ensuring the entire monthly rent is paid. Speak with your roommate and try to resolve the issue in writing. If payment remains unpaid, notify your landlord. For further dispute resolution, you may contact the Rentalsman using Form 1: Application for Assistance.
  2. Can a landlord evict one roommate but not others in New Brunswick?
    Typically, eviction procedures apply to all tenants named on a joint lease. However, for individual leases, the landlord may only end tenancy for the specific person involved. Always check your lease details and seek legal advice if you receive an eviction notice.
  3. How is a security deposit handled when roommates move out at different times?
    If the deposit was paid jointly, the landlord is not required to return partial deposits when just one person leaves. The full deposit is usually returned at the end of the tenancy. It's important for roommates to work out a fair agreement between themselves if someone leaves early.
  4. Are there noise or guest rules for shared rentals?
    All tenants must comply with local bylaws and any quiet hours or guest rules in the lease. Discuss and document house rules with your roommates to avoid disputes.
  5. Is it legal to sublet my room in a shared house?
    Subletting is allowed with landlord approval in most cases. Always get written permission and follow the rules under the New Brunswick Residential Tenancies Act.
  1. How do I file a complaint about my landlord or roommate in shared housing?
    Use Form 1: Application for Assistance from the Rentalsman’s office. Fill out the details of your issue and submit the form online, by mail, or in person.
  2. How can I end my portion of a joint lease if I want to move out?
    Give written notice to your landlord, and discuss with your roommates and landlord whether you will be replaced or if the lease needs to be updated. Use Form 2: Notice to Terminate a Tenancy if required.
  3. How do I divide utilities and cleaning duties fairly with roommates?
    Set up a written roommate agreement outlining payment dates and task splits. Update it as needed if household members change.
