Common Roommate Mistakes to Avoid in Northwest Territories

Roommates & Shared Housing Northwest Territories 5 min read · published March 09, 2026 Flag of Northwest Territories

Living with roommates is a practical way to share costs and build communities—especially in the Northwest Territories where housing can be limited and expensive. However, misunderstandings or simple oversights can quickly turn shared living into a stressful situation. By understanding your rights, responsibilities, and common pitfalls, you can create a positive experience and avoid typical mistakes many tenants make in shared housing.

In the Northwest Territories, rights and responsibilities under tenancy come from being named on the lease. If you’re not listed on the lease, you generally cannot enforce against the landlord directly; ask the landlord to add you to the lease or consult the Rental Officer for options.

Understanding Roommate vs. Tenant Rights in the Northwest Territories

Common Mistake #1: Assuming All Roommates Have Equal Legal Rights

  • Only signed tenants can contact the Rental Office for disputes with the landlord.
  • Informal roommate agreements (verbal or written between roommates) are not covered under tenancy laws.
  • All adults should be named on the lease for maximum protection.
Whenever possible, request all roommates be officially added to the tenancy agreement. This gives everyone equal rights and responsibilities.

Common Mistake #2: Overlooking Financial Arrangements

Financial misunderstandings are a top cause of shared housing conflict. Before moving in together, clearly outline:

  • How rent and utilities will be divided.
  • Payment deadlines and methods.
  • Who will pay the security deposit and hold responsibility for damages.

Landlords in the Northwest Territories may require a security deposit ("damage deposit") not exceeding one month's rent. Only tenants on the lease can expect a deposit return process conducted by the landlord. To avoid issues, consider drafting a written roommate agreement outlining internal repayments and shared responsibilities.

Keep a written roommate agreement and keep copies of receipts, the lease, and any notice or reminders about due dates. This helps prevent arguments over payments and deposits.

Common Mistake #3: Neglecting Safety and Property Conditions

Shared housing often raises concerns about safety, cleanliness, and maintenance. All tenants have the right to a safe and habitable home. The landlord must provide regular repairs and ensure essential services (heat, water, electricity) are functioning.

  • If a roommate causes property damage, all signed tenants can be held jointly responsible by the landlord.
  • If you encounter health or safety issues—such as insufficient heat, mold, or pest infestations—communicate quickly with your landlord and document the problem.

Key Forms and Roommate Scenarios in the Northwest Territories

If problems arise—like a roommate moving out early or refusing to pay their share—signed tenants are responsible for covering the full rent to avoid eviction. If you want to formally change, add, or remove tenants from your agreement, work with your landlord and use official forms. The most important forms include:

Using official forms and following the appropriate notice or filing steps protects your tenancy; keep dated copies of any forms you submit and ask for confirmation from the landlord.
  • Notice to Terminate Tenancy by Tenant (Form NTT): Tenants who wish to leave a tenancy must give the landlord written notice. This form can be found on the Government of Northwest Territories Residential Tenancies Forms page.
    Example: If one roommate wishes to leave, they fill out a Notice to Terminate and provide the required notice period based on their lease.
  • Application to Rental Officer (Form Application): Used when resolving disputes—such as disagreements with the landlord about deposit returns, repairs, or occupancy. The form and instructions are officially available here.
    Example: If your ex-roommate refuses to pay outstanding rent that affects your tenancy, you may use this form to seek a ruling from the Rental Officer.

Tips to Maintain Healthy Roommate Relationships

  • Discuss house rules (quiet hours, shared spaces, pets) early, and put them in writing.
  • Communicate regularly to resolve challenges before they escalate.
  • Conduct an inspection with all roommates present when moving in and out.
  • Keep copies of all agreements, receipts, and correspondence.

If a conflict does arise, tenants should try to resolve issues through dialogue. For serious or persistent problems, you may need to follow the formal complaint or application process via the Rental Officer.

Summary: Avoiding Roommate Pitfalls

  1. Who is responsible for unpaid rent if a roommate leaves? If both roommates are signed tenants, all are "jointly and severally liable"—meaning the landlord can pursue any or all tenants for the full rent amount. If you are not on the lease, your co-tenant is legally responsible to the landlord, but you may be indebted to them via a roommate agreement.
  2. What happens to the security deposit if one roommate moves out? The landlord must return the deposit only to the tenants listed on the lease, less any deductions for damages (see your lease agreement). Roommates should arrange privately how deposits are repaid among themselves.
  3. Can I remove a disruptive roommate? Tenants can only be removed from a lease or rental unit if the landlord agrees and the proper notice is given. Otherwise, roommate removal usually requires mutual agreement or legal proceedings through territorial court if necessary.
  4. Do all roommates need to be present for inspections? It's recommended, but not required. Having all tenants present ensures everyone agrees on the state of the unit at move-in or move-out—protecting everyone from future disputes.
  5. Where can I get help with a roommate or shared housing dispute? Contact the Rental Officer for Northwest Territories or a local tenant advocacy group for guidance or to file a formal complaint.
  1. How to add a new roommate to my lease? 1) Ask your landlord if they permit another tenant. 2) The landlord may require the new roommate to fill out an application or undergo a background check. 3) Once approved, update the written rental agreement.
  2. How to remove your name from a roommate lease? 1) Give proper written notice using the Notice to Terminate Tenancy by Tenant form. 2) Secure the landlord’s acknowledgment in writing. 3) Settle your financial responsibilities before moving out.
  3. How to document the unit’s condition when sharing housing? 1) Take photos of each room at move-in and move-out. 2) Have all inbound roommates sign an inventory or inspection report. 3) Retain copies for your records.
