Subletting and Lease Assignment Rules in Alberta

Moving In / Out Alberta 3 min read · published March 09, 2026 Flag of Alberta

If youre renting in Alberta and considering subletting or assigning your lease, it helps to know your rights and the practical steps to follow. Tenants and renters must check their rental agreement for clauses about subletting or assignment, ask for written landlord consent where required, and document any agreements. Alberta has a formal dispute process through the Residential Tenancy Dispute Resolution Service (RTDRS) if consent is unfairly withheld or disputes arise. This article explains the difference between subletting and lease assignment, when landlord permission is needed, the official forms you may use, and how to protect yourself as a tenant when finding a replacement. Practical tips and steps focus on keeping records and meeting notice and filing deadlines.

Understanding subletting and assignment

Subletting lets a tenant rent part or all of their unit to someone else while they remain legally responsible under the original lease. A lease assignment transfers the tenant's legal rights and obligations to a new tenant. Both are affected by the Residential Tenancies Act[1] and can be subject to disputes decided by the RTDRS[2].

When you can sublet or assign

  • Check your lease for any subletting or assignment clause.
  • Ask the landlord in writing for consent or a clear response within any timeline set by the lease.
  • Agree who will pay rent and whether the subtenant pays the original tenant or the landlord directly.
  • Document the sublet or assignment in a signed agreement that includes dates, rent and responsibilities.
Keep a signed copy of any sublet agreement and all rent receipts.

What if a landlord refuses?

If a landlord unreasonably withholds consent, you can apply to the RTDRS for a decision. Before applying, gather your lease, written requests, responses, and any ad or screening evidence for a replacement tenant. You may need official forms such as the Application for Dispute Resolution and tenancy templates available on Alberta government pages[3].

FAQ

Can I sublet without telling my landlord?
No. You should check your lease and get written permission if required; remaining in breach can lead to eviction or legal claims.
Do I stay responsible for damage and rent when I sublet?
Yes. In a sublet the original tenant usually remains responsible to the landlord for rent and damages unless the lease is assigned.
How long does an RTDRS decision take?
Timing varies, but you should file promptly and follow RTDRS directions; check the RTDRS site for current timelines.

How-To

  1. Submit a written request to your landlord asking for permission to sublet or assign the lease.
  2. Screen and vet potential subtenants and keep written records of communications and references.
  3. Create a written sublet or assignment agreement that states rent, dates and who pays utilities.
  4. Get the landlord's written consent or, if refused, collect evidence and consider filing an RTDRS application.
  5. If moving out, follow the notice procedures or see guidance on What to Do If You Need to Leave Your Rental Before the Lease Expires.
  6. If unsure, contact tenant advisory services or the RTDRS for steps and forms.

Key Takeaways

  • Always check your lease and get written permission when required.
  • Document every step: requests, responses, agreements and payments.
  • If disputes arise, the RTDRS can hear cases about withheld consent.

If you need to advertise or find a replacement tenant, consider trusted listing sites to speed the process, for example Find rental homes across Canada on Houseme. For guidance on ending tenancy properly see How to Properly End Your Rental Agreement as a Tenant.
