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

Living with roommates or sharing a rental in New Brunswick can be a practical and affordable option, but it comes with specific legal considerations. Whether you’re entering a new roommate arrangement, dealing with shared expenses, or facing disputes, understanding your rights and responsibilities is crucial for a positive co-living experience. This guide answers common questions about shared housing and roommate issues under New Brunswick law so you can make informed decisions.

Roommate Arrangements in New Brunswick: An Overview

Roommates can live together under different arrangements: everyone on the lease, subletting, or informal shared-living without all names listed on the agreement. It's important to understand how the law treats each scenario, especially regarding rent payments, security deposits, and legal obligations.

Do All Roommates Have the Same Legal Rights?

Only tenants who have signed the lease or are listed on the official rental agreement are considered legal tenants under New Brunswick’s Residential Tenancies Act. Roommates not on the lease may have fewer protections, and resolving conflicts may be more challenging.

  • If you are listed on the lease, you share full legal responsibility with your co-tenants for paying rent and following the rental rules.
  • Informal roommates or subtenants are not always covered by the Act. Their rights depend on any written agreement between the parties.

What Should Be in a Roommate Agreement?

While a roommate agreement is not required under New Brunswick law, having a written agreement is highly recommended. It can outline:

  • How rent and utility costs are divided
  • Shared responsibilities for cleaning and maintenance
  • What happens if someone wants to move out or bring in a new roommate
  • Rules about guests and shared spaces
Consider having all roommates sign a written agreement. It helps prevent misunderstandings and provides a record if disputes arise later.

Who Is Responsible for the Security Deposit?

In New Brunswick, only tenants named on the lease are legally responsible for the security deposit paid to the landlord. The maximum amount is typically one month's rent. If a roommate moves out, the landlord usually returns the deposit at the end of the tenancy, not to individual roommates. For more information, see Understanding Rental Deposits: What Tenants Need to Know.

What Are the Maintenance and Safety Obligations in Shared Housing?

Maintenance and repair obligations are shared among legal tenants, unless otherwise agreed. All tenants have the right to a safe, healthy living environment. If health or safety issues (like mold or lack of heat) affect your unit, tenants should notify the landlord in writing. To learn more about keeping your rental safe, check Health and Safety Issues Every Tenant Should Know When Renting.

If you notice health or safety problems, document dates and issues in writing and keep copies. Request a written plan and timeline from the landlord for fixes, and follow up in writing if repairs aren't made promptly. If problems worsen, contact local health authorities or a tenant advocacy service for guidance.

Ending a Roommate Arrangement or Moving Out

When a roommate wants to leave, the process depends on your rental agreement. If all roommates are on the lease, you must collectively follow the rules for providing notice.

  • If you wish to end the entire tenancy, use the official Notice of Termination (Form 6) from the New Brunswick Residential Tenancies Tribunal.

  • Tenants normally must give a minimum notice (usually one month), but review your agreement in case different rules apply.
  • If only one roommate leaves, the remaining tenants and landlord should agree on how to handle rent and updates to the lease.

Key tip: Always provide written notice using the correct form and keep a copy as proof. Communication with your landlord and co-tenants is crucial for a smooth move-out process.

What If Disputes Arise Between Roommates?

Disputes between roommates—like issues about cleaning, guests, or shared bills—are usually considered private matters. The landlord or the Residential Tenancies Tribunal generally does not get involved in conflicts between tenants unless the lease, property, or rental payments are affected. If you and your roommate are both on the lease, you are jointly responsible for rent. If one person does not pay, the landlord can pursue any or all co-tenants for the full amount owed.

Frequently Asked Questions

  1. If my roommate moves out, do I have to pay their share of the rent?
    Yes, if you are listed as a tenant on the lease, you are jointly responsible for the entire rent. It's important to discuss how rent will be managed before a roommate leaves.
  2. Can the landlord evict one roommate but not the others?
    Usually, if one tenant violates the lease, the landlord may take action against all tenants named on the lease. Individual removals are rare and depend on lease terms.
  3. What happens to our deposit if a roommate leaves early?
    The security deposit stays with the landlord until all tenants vacate. Roommates can settle their share privately, but the landlord returns the deposit to all tenants at the end of the lease.

    No, roommate-to-roommate issues are generally private matters unless they affect the lease or the landlord's property.
