Alberta Cannabis Home-Grow Plant Limit: Four per Household
Adults-only educational information, not legal advice. Cannabis rules can change. Check the current federal, provincial, municipal, and property rules before acting.
The short answer
In Alberta, the federal personal-cultivation limit is up to four cannabis plants per dwelling-household--not four plants for each adult. Health Canada says adults may grow up to four plants per dwelling-household from legal seeds or seedlings, subject to provincial and territorial restrictions. This is a ceiling, not a guarantee that a particular home or tenancy permits growing.
Check the home before you grow
Before buying seeds or starting a grow, check three things:
- Property terms: Read your lease, rental agreement, and any condominium bylaws. Alberta's tenancy guidance says landlords and condominium corporations may prohibit growing cannabis plants. A medical cannabis document does not automatically exempt a tenant from a growing restriction.
- Local rules: Ask your municipality whether local requirements apply to your address, such as zoning, fire safety, electrical safety, inspection, and remediation requirements. Do not rely on another Alberta city's rules.
- Federal conditions: Confirm the current Cannabis Act guidance, including the household plant limit and prohibition on explosive or highly flammable organic solvents.
If a rule is unclear or a dispute could affect housing, get advice from an Alberta legal service before planting. This guide cannot determine how a lease or bylaw applies to your circumstances.
Keep the household safe
Keep plants and harvested cannabis secured from children, youth, pets, and visitors. Store cannabis in a locked place and do not leave products or growing materials where a child could mistake them for food. Follow applicable fire and electrical safety requirements. Do not use explosive or highly flammable organic solvents, including butane or propane, to make cannabis products at home.
