Smoking and Cannabis Rules in Shared Rentals (Alberta)

Roommates & Shared Housing Alberta 4 min read · published March 29, 2026 Flag of Alberta
Living with roommates in Alberta raises many questions about smoking and cannabis in shared rentals, and tenants and renters need clear, practical guidance. This article explains how provincial rules, lease clauses and building policies can affect where smoking is allowed, what landlords can enforce, and what steps you can take if second-hand smoke creates health or habitability concerns. It covers tenant rights, how to document problems, official complaint and dispute routes, and common forms used in Alberta so you can make informed decisions and protect your health and tenancy in shared housing situations. Read the sections below for quick action steps and links to official resources and forms.

Where smoking and cannabis rules come from

Three sources commonly determine rules in shared rentals: provincial law, the lease or rental agreement, and building or landlord policies. Alberta's Residential Tenancies Act sets baseline tenant and landlord obligations, while individual leases may add specific smoking or cannabis restrictions. When a lease clearly bans smoking or cannabis in units or common areas, tenants are usually required to follow that rule, even if the substance is legal federally or provincially.[1]

Keep a dated log of smoke incidents and communications with roommates or landlords.

Common situations and what they mean

Smoking inside a private room versus common areas

If a lease allows smoking in private rooms but bans it in common areas, tenants should follow those boundaries. Landlords can set reasonable rules about common spaces and may prohibit smoking in common hallways, laundry rooms and entrances to protect other tenants.

Whole-building no-smoking policies

Some landlords adopt whole-building no-smoking or smoke-free policies and include them in leases or add them at renewal. When introduced properly and included in the written rental agreement, these policies are enforceable under Alberta tenancy rules.

Medical cannabis and accommodation requests

Medical use of cannabis raises accommodation questions. Tenants who need cannabis for medical reasons should discuss reasonable accommodations with their landlord; however, accommodation does not automatically override another tenant's serious health concerns from second-hand smoke.

How to address second-hand smoke in shared housing

Follow a stepwise approach: document the issue, review your lease, talk to the smoker, notify the landlord in writing, and request remedies if the problem continues. Evidence such as dated photos, notes of times and smells, and written communications strengthen any request to change behaviour or to enforce lease rules.

  • Document each incident with dates, times and descriptions.
  • Check your lease for explicit smoking or cannabis clauses and note relevant wording.
  • Speak respectfully with the roommate first and try to agree on boundaries or ventilation steps.
  • If a voluntary solution fails, send a clear written complaint to the landlord describing the impact and requested remedy.
Early, calm communication often resolves many shared-housing smoking disputes.

When to involve official dispute resolution

If the landlord does not address a serious smoke problem or refuses to enforce a lease clause, tenants in Alberta can apply to the Residential Tenancy Dispute Resolution Service (RTDRS) or seek other remedies under the Residential Tenancies Act. The RTDRS handles disputes about tenant obligations, landlord responsibilities and certain breaches of tenancy agreements.[2]

Practical examples and forms

Two forms commonly used in Alberta tenancy matters are the written complaint/notice to landlord and the RTDRS application form. Use a written complaint to create a record asking the landlord to enforce the lease or to fix habitability issues caused by smoke. If the issue continues, the RTDRS application is used to request a formal hearing and decision. Find RTDRS forms and instructions on the official RTDRS forms page when you are ready to file.[3]

File official forms carefully and keep copies of everything you submit.

Rights and responsibilities for roommates

In shared rentals, all tenants should follow the signed lease and any building safety rules. Tenants have a responsibility not to unreasonably interfere with others' reasonable enjoyment of the rental unit. Landlords must maintain basic habitability standards and respond to complaints that threaten health or safety.

Resolving disputes without RTDRS

Before applying to RTDRS, try these steps: negotiate with roommates, propose time-limited compromises (e.g., designated outdoor smoking areas), use air purifiers, or agree on written house rules. If informal steps don't work, escalate with written notices to the landlord and document the landlord's responses.

FAQ

Can a roommate stop me from using legal cannabis in my private room?
Not necessarily; if your lease permits smoking in private rooms you may be allowed to use cannabis there, but you must still avoid unreasonably affecting other tenants and follow any building rules that are part of the lease.
Can a landlord impose a no-smoking rule in shared rentals?
Yes. Landlords can include no-smoking or smoke-free clauses in leases and may enforce whole-building policies when they are part of the agreement and applied consistently.
What should I do if smoke from another unit affects my health?
Document incidents, inform your landlord in writing, request remedies, and if necessary apply to the RTDRS for dispute resolution with supporting evidence.

How-To

  1. Document the problem with dates, times and photos or notes.
  2. Review your lease for smoking or cannabis clauses and note exact wording to cite.
  3. Talk to your roommate and propose a written agreement or compromise to reduce smoke exposure.
  4. Send a written complaint to the landlord requesting enforcement or remediation and keep a copy.
  5. If the landlord does not act, prepare and submit an RTDRS application with your documentation.
