Smoking and Cannabis in an Alberta Lease
What you can ban, when a new rule needs the tenant's written consent, and what to do if a tenant breaks it.
Last updated: October 2026
Short answer
Yes, an Alberta landlord may ban smoking of all substances, including cannabis, and may ban growing cannabis, through the rental agreement. A rule added during a tenancy needs the tenants' written consent, and repeated breaches may be a substantial breach heard by RTDRS or the Court of Justice.
Can you ban smoking and cannabis in an Alberta rental?
Yes. The RTA Handbook says a landlord or condo board may prohibit the smoking of all substances, including cannabis, in their buildings or on their properties. A landlord may also prohibit growing cannabis in the rental agreement.
The ban works because it is a term of the tenancy, not because a provincial law bans smoking inside a unit. No provincial ban on smoking inside a private unit was found, so your lease is what makes it enforceable.
What provincial law already bans
The Tobacco, Smoking and Vaping Reduction Act bans smoking and vaping in a "public place". That term includes the common areas of a multi-unit residential building, such as patios, pools, other recreation areas and enclosed parking garages. The Gaming, Liquor and Cannabis Act bans smoking or vaping cannabis wherever tobacco smoking is banned, so the common-area ban covers cannabis too.
One narrow exception runs the other way. A private residence counts as a workplace, and so is smoke-free, if a home business is run there and the owner has employees who work in the home but do not live there.
Tenants renting a condo must also follow the condo bylaws, whether or not those bylaws appear in the tenancy agreement. Check the bylaws before you write your own clause.
Adding the ban at signing versus mid-tenancy
The easiest time is before the lease is signed. Put the rule in the agreement, point to it, and the tenant agrees to it by signing.
Mid-tenancy is different. The Handbook says landlords can change or add rules during the tenancy only with the tenants' written consent. Without that consent, a new rule cannot be imposed until the tenancy ends. In the same way, the agreement cannot be changed unless both parties agree or the law allows it, and any change should be in writing and signed by both of you.
A periodic tenancy can end only for the prescribed reasons, and a new house rule is not one of them. So if you want a ban added to a running tenancy, ask the tenant for a signed amendment. For fixed terms, the new rule can go into the next agreement.
What to put in the lease clause
A clear clause avoids arguments later. Cover these points:
- Substances: tobacco, cannabis, vaping devices and any other smoking.
- Places: inside the unit, and any balcony, patio, yard or other area you want covered.
- Growing: state whether growing cannabis is allowed. The Handbook confirms you may prohibit it.
- Cleaning: a landlord can deduct cleaning from the deposit only if the tenant agreed to it, so say what the tenant agrees to.
- Required statement: a written lease must still carry the larger-print statement. See the Alberta forms and wording guide.
The Handbook also notes that restrictions on medical cannabis use in rentals have not been addressed in Alberta courts or legislation. If a tenant raises a medical need, get legal advice before you act.
What to do if the tenant breaks the rule
- Document it. Write down dates, what you saw or smelled, and any complaints from neighbours.
- Warn in writing. Point to the lease clause and ask the tenant to stop.
- If it continues, consider a 14 day notice for a substantial breach. The Handbook says that repeated violation of smoking rules may be a substantial breach, and that the landlord may apply to terminate the tenancy.
- Expect an objection. The tenant can object in writing before the 14 days end. Then you must apply to RTDRS or court, and the tenant may stay until there is an order.
One incident may not be enough. See what to do if a tenant violates the lease and how to evict a tenant in Alberta.
Smoke damage and the deposit
Smoke damage is a deposit question, not just a lease one. The Handbook says cigarette burns are not normal wear and tear, and no deduction is allowed for normal wear and tear. You can make deductions only as the tenant agreed in the lease, and damage deductions require that the move-in and move-out inspection reports were done. The Alberta landlord security deposit guide covers the deadlines.
Disputes go to the Residential Tenancy Dispute Resolution Service or the Court of Justice. This guide explains the rules in general terms; for a specific case, ask the tribunal or a licensed legal professional.
Frequently Asked Questions
Can I put a no-smoking clause in my Alberta lease?
Yes. A landlord may prohibit smoking of all substances, including cannabis, in the rental agreement.
Can I ban cannabis smoking and vaping too?
Yes. The Handbook says a landlord may ban smoking of all substances including cannabis, and provincial law already bans cannabis smoking and vaping wherever tobacco smoking is banned, including common areas of multi-unit buildings.
Can I stop a tenant from growing cannabis?
Yes. The Handbook says a landlord may prohibit the growing of cannabis in the rental agreement. Put the ban in the lease.
Can I add a smoking ban to an existing tenancy?
Only with the tenants' written consent. Without it, a new rule cannot be imposed until the tenancy ends.
Is smoking banned in the common areas of an Alberta apartment building?
Yes. Provincial law treats the common areas of a multi-unit residential building as a public place, including patios, pools, recreation areas and enclosed parking garages.
Can I evict a tenant for smoking?
Repeated violation of a smoking rule may be a substantial breach. The landlord may give at least 14 days' notice or apply to RTDRS or court, and the tenant can object in writing, which means the landlord must get an order.
Do condo bylaws apply to a tenant?
Yes. The Handbook says tenants renting a condo must comply with the condo bylaws, whether or not they are written into the tenancy agreement.
What about medical cannabis?
