Roommates & Shared Housing Rules for Alberta Tenants

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

Shared housing is a popular choice for many in Alberta, including students, professionals, and anyone seeking affordable living options. Whether you’re finding a roommate for a two-bedroom apartment or moving into an established shared home, it’s essential to understand the laws, agreements, and practical steps unique to Alberta tenants living with roommates.

Shared Housing in Alberta: Basics for Tenants

Shared housing refers to situations where multiple tenants live together, sharing spaces like kitchens and bathrooms. You might each sign your own lease, or there may be one main leaseholder with subtenants or additional occupants. These living arrangements carry both unique benefits and specific legal responsibilities under Alberta’s laws.

  • Roommates: People living together, often on the same lease, sharing rental payments and responsibilities.
  • Subtenants: Tenants renting from another tenant (not directly from the landlord), with the original leaseholder still legally responsible.
  • Occupants: People living in the unit but not named on the lease—may have limited rights.
Always clarify and put roommate agreements in writing before moving in. This helps prevent confusion about rent, bills, chores, and notice requirements.

Your Rights & Responsibilities in Shared Housing

Alberta tenants living with roommates must follow provincial law, usually the Residential Tenancies Act1. Each person’s rights may depend on whether they’re a co-tenant, subtenant, or simply an occupant.

  • If you sign the lease with the landlord, you have full tenant rights and obligations.
  • Co-tenants are each responsible for the full rent and any damages—if one person doesn’t pay, the landlord can pursue others for unpaid rent.
  • If you are a subtenant, your main legal relationship is with the tenant who sublet the room to you, not the landlord directly.

Deposits in Shared Housing

In Alberta, security deposits (damage deposits) must not exceed one month’s rent. Clarify in writing before moving in:

  • Who paid the deposit, and in what amount?
  • How any deductions or refunds will be handled when a roommate moves out?

Ending a Roommate Situation or Sublease

If problems arise, or a roommate decides to leave, know that Alberta law outlines specific procedures for giving notice and ending agreements:

  • If everyone signed the lease, all tenants must agree to end the tenancy or give legal notice.
  • If you’re subletting, ending your subtenancy requires written notice to the original tenant, in line with the Residential Tenancies Act.
If all tenants are on the lease, the landlord generally must approve ending the tenancy for everyone; you can't unilaterally remove a roommate. Consider requesting a lease amendment or a new agreement with landlord consent.

Key Forms for Roommates and Shared Housing

  • Notice to Terminate a Periodic Tenancy (Form C): Use this if you wish to legally end your rental agreement—a common need when a roommate moves out. View official instructions and download
  • Inspection Report (Legal Requirement): Must be completed at the start and end of every tenancy. Vital when roommates change, as it documents the unit's state and helps prevent deposit disputes. Learn more and access the form

If Disputes or Issues Arise

Roommate disagreements, damage, or unpaid rent can quickly get complicated. Try these steps:

  • Start with a direct, written conversation about the issue.
  • Document all communications and agreements.
  • If a resolution isn’t possible, you may bring certain disputes to the RTDRS, Alberta’s official tenancy tribunal, or the Provincial Court.
If disputes persist, keep a careful timeline of events and copies of messages; you can prepare and file with RTDRS if needed and collect evidence for hearings.

Best Practices for Smooth Roommate Living

Prevention is key. Establish ground rules and document who is responsible for:

  • Rent payments and split amounts
  • Paying utility bills
  • Handling chores and cleaning schedules
  • Notifying the landlord of problems or repairs

With clear communication and an upfront agreement, you’ll avoid most problems before they start. For those looking for new accommodations or shared spaces, Find rental homes across Canada on Houseme to compare the latest available units easily.

  1. Can my landlord evict just one roommate if there’s trouble?
    Usually, if you and your roommates are all on the lease, the landlord must deal with everyone as one unit. If only one is causing problems, all roommates could face eviction unless a separate agreement exists. In some cases, you can negotiate a new lease that excludes the problematic roommate, but this requires landlord approval.
  2. Do I have to pay my roommate’s share of rent if they move out?
    If you are a co-tenant (on the lease), you can be held responsible for the full rent if your roommate leaves. Make sure to have a roommate agreement to clarify how shared expenses will be managed if this occurs.
  3. How do we split the security deposit when moving out?
    In Alberta, the landlord must return the deposit to whoever paid it. If multiple roommates contributed, agree in writing beforehand on how to split the deposit at the end of the tenancy and ensure all inspection reports are complete.
  4. Can a roommate sublet their room without my consent?
    In most cases, permission from all tenants and the landlord is required before a roommate can sublet their room. Always check your lease agreement and seek written approvals.
  5. What if I want to bring in a new roommate?
    Get your landlord’s written approval before adding a new tenant or changing roommates. The landlord may require a new application or rental agreement.
  1. How do I end my part of a joint lease if my roommate wants to stay?
    Notify your landlord in writing as soon as possible. All tenants on a joint lease are typically responsible for the full rent unless the landlord allows a lease change.
  2. How can I document the unit’s condition when moving in or out?
    Complete an Inspection Report as required by law. Take photos and have all tenants sign the report.
  3. How do I make a complaint about a roommate who is damaging the property?
    Document the problem, talk to your roommate first, then raise the issue with your landlord if it impacts the tenancy. If unresolved, contact the RTDRS for help.
