Adding a Roommate: Notice Requirements in NWT

Roommates & Shared Housing Northwest Territories 3 min read · published June 24, 2026 Flag of Northwest Territories

Adding a roommate affects both tenancy rights and responsibilities. If you rent in the Northwest Territories, you should understand when you must give notice to a landlord, what forms or permissions may be required, and how a new occupant can affect rent, deposits, or applications of the tenancy agreement. This guide explains common scenarios for tenants and renters — from sharing utilities and signing a joint lease to subletting or replacing a name on the lease — and outlines practical steps to protect your interests. Read on to learn deadlines, documentation to keep, how to involve the territorial tribunal if disputes arise, and where to find official forms and help.

When you need to tell your landlord

In many cases adding a roommate means you must tell your landlord in writing. Whether you need permission depends on the lease wording: some agreements explicitly allow additional occupants, others require written consent or a formal lease change. If the landlord must approve new occupants, they should respond within a reasonable time or follow any timelines set out in territorial rules. If your lease forbids subletting or adding names, discuss options so everyone understands the consequences.

Keep a dated copy of any notice you send or receive.

Common scenarios and what to do

  • If you want to add an occupant to your existing lease, ask the landlord for written consent and a signed amendment.
  • If you plan to sublet your unit, confirm whether subletting is allowed and follow any required notice or application procedures.
  • If rent will be shared or the landlord will change who is responsible for payment, get any new rent arrangement in writing.
  • If deposits or keys change hands, document the condition of the unit and provide receipts.
Documented agreements reduce misunderstandings later.

Forms, tribunal and official rules

The territorial Residential Tenancies Office handles disputes and applications in the Northwest Territories. Residential Tenancies Office[1] The governing law is the Residential Tenancies Act; it explains notice rules, subletting, and when an occupant becomes a tenant under the law. Residential Tenancies Act[2]

Common forms and when to use them:

  • Application to the Residential Tenancies Office (used when you need the tribunal to resolve a disagreement) — for example, a tenant asks the tribunal to decide if a landlord unreasonably refused consent to a roommate.
  • Notice to landlord or tenant (used to give written notice of a change, such as adding or removing an occupant) — use this to record the date you informed the landlord and the details of the change.
You should file applications early if deadlines apply to your situation.

Practical steps for tenants

Follow these steps to reduce risk when adding a roommate or change in occupancy:

  • Review your lease to see what it says about additional occupants or subletting.
  • Get all agreements in writing, including who pays rent and how utilities are split.
  • Contact the Residential Tenancies Office early if you anticipate a dispute or need clarity on rights.
Verbal agreements are hard to enforce; always get written confirmation.

Lease changes, deposits and responsibility

If a roommate is added to a lease, they may become a co-tenant and share legal responsibility for rent and damages. If the landlord requires a new security deposit or an updated tenancy agreement, ask for a receipt and keep copies.

FAQ

Do I always need my landlord's permission to add a roommate?
Not always; it depends on your lease terms. If the lease prohibits additional occupants or subletting, you typically need written permission or a formal lease amendment.
Can a roommate become legally responsible for rent?
Yes. If the landlord adds the roommate to the lease or the roommate signs the tenancy agreement, they usually share legal responsibility for rent and damages.
What if a landlord refuses permission without reason?
You can request a written explanation and, if necessary, apply to the Residential Tenancies Office for a resolution.

How-To

  1. Check your lease for clauses about adding occupants or subletting.
  2. Write a clear notice to your landlord describing the proposed roommate and any changes to rent or deposits.
  3. Keep evidence: dated letters, emails, receipts, and photos of the unit condition.
  4. If the landlord refuses or a dispute arises, contact the Residential Tenancies Office for guidance or file an application.
