Do You Need a Written Lease in Alberta?
No — verbal tenancy agreements are legally valid in Alberta. However, a written lease is strongly recommended for both parties. It documents agreed-upon terms, reduces disputes, and provides evidence for RTDRS or court proceedings.
What Must Be in an Alberta Lease
While there's no single prescribed form for Alberta residential leases, a valid agreement should include: names of all tenants and the landlord, civic address of the rental unit, start date, rent amount and due date, payment method, deposit amount, lease term (fixed or periodic), and signatures of all parties.
Protective Clauses to Include
- Pet clause: Clearly state whether pets are permitted, what types, and any associated fees or conditions.
- Smoking clause: Prohibit smoking inside the unit and within a specified distance of entrances.
- Subletting clause: Specify whether subletting is permitted and the approval process required.
- Guest policy: Define long-term guest rules to prevent unauthorized occupancy.
- Maintenance request process: Specify how tenants must submit repair requests.
- Tenant insurance requirement: Require proof of tenant insurance with a minimum liability amount.
- Inspection clause: Commit to conducting move-in and move-out inspections together.
Common Lease Mistakes
- Not listing all occupants (creates issues with unauthorized occupants)
- Vague pet policies ("negotiable" opens disputes)
- Missing the deposit amount and trust account info
- Using an outdated or out-of-province template
- Including illegal clauses (e.g., waiving tenant rights under the RTA)
Note: Illegal Lease Clauses Are Void
Any clause that purports to waive a tenant's statutory rights under the Alberta RTA is void — even if signed. For example, a clause stating "tenant waives the right to dispute rent increases" is unenforceable.
