Alberta Lease Requirements: Mandatory Terms, Prohibited Clauses, and Agreement Rules

Alberta's Residential Tenancies Act (RTA) establishes the framework for tenancy agreements, including what must be included, what cannot be enforced, and how different tenancy types work. Having a properly drafted lease protects both landlords and tenants and reduces the risk of disputes.

Written vs. Oral Lease Agreements

Alberta recognizes both written and oral tenancy agreements. However, a written agreement is strongly recommended because:

• It provides clear documentation of all agreed-upon terms
• It protects the landlord's ability to enforce specific conditions (pet policies, parking rules, etc.)
• The landlord must provide a copy to the tenant within 21 days of signing (RTA, s. 5(2))
• Oral agreements are harder to prove and may default to standard RTA provisions

If there is no written lease, the terms of the tenancy default to the provisions of the Residential Tenancies Act.

Essential Lease Terms

Every tenancy agreement should include the following:

Types of Tenancy

Fixed-Term Tenancy

• Has a specific start and end date
• Ends automatically on the end date — no notice required from either party
• Rent cannot be increased during the term unless the agreement explicitly allows it
• If the tenant stays past the end date without signing a new lease, the tenancy typically becomes periodic (month-to-month)

Periodic Tenancy

• Runs continually (e.g., month-to-month, week-to-week) until terminated by either party
• Requires proper notice to terminate:
• Tenant: 1 month's notice (monthly) or 1 week (weekly)
• Landlord: 3 months' notice (monthly) or 1 week (weekly)

Prohibited Clauses

The RTA renders certain lease clauses void and unenforceable, even if the tenant agrees to them:

1. Waiver of tenant rights — Cannot require tenants to give up protections under the RTA
2. Payment of rent as security deposit — Cannot require a tenant to pay a security deposit greater than one month's rent
3. Automatic rent increases — Fixed-term leases cannot include escalation clauses that bypass the 365-day rule
4. Penalties for normal wear and tear — Cannot make tenants responsible for ordinary depreciation
5. Prohibition on contacting authorities — Cannot restrict tenants from contacting bylaw enforcement, health inspectors, or the RTDRS
6. Limiting the right to sublet — While subletting requires landlord consent, consent cannot be unreasonably withheld

Subletting and Assignment

Subletting

• Requires the landlord's written consent
• Consent cannot be unreasonably withheld
• The original tenant remains responsible for the lease obligations
• The subletter must comply with all terms of the original lease

Assignment

• Transfers the entire tenancy to a new tenant
• Also requires landlord consent
• The original tenant is released from future obligations once the assignment is complete

If a landlord unreasonably refuses to consent to a sublet or assignment, the tenant may apply to the RTDRS for relief.

Early Termination

A tenancy agreement can be ended early in limited circumstances:

1. Mutual agreement — Both landlord and tenant agree in writing to end the tenancy early
2. Substantial breach — Either party can issue a 14-day notice for a substantial breach
3. Domestic violence — Victims of domestic violence may terminate a tenancy early by providing a 28-day notice along with supporting documentation (protective order, emergency protection order, or certificate from a designated authority)
4. Abandoned premises — If a tenant abandons the rental unit, the landlord may retake possession following proper procedures

Renewal and Continuation

• Fixed-term leases do not automatically renew — the tenant either signs a new lease or the tenancy becomes periodic
• Periodic tenancies continue until proper notice is given by either party
• Landlords should discuss renewal terms at least 3-4 months before a fixed-term lease expires to allow for proper notice of any changes

Best Practices for Landlords

1. Always use a written lease — Include all key terms and have both parties sign
2. Provide a copy within 21 days — It's a legal requirement
3. Review the RTA regularly — Ensure your lease does not contain prohibited clauses
4. Use clear language — Avoid legal jargon; tenants should understand their obligations
5. Include a pet addendum — If pets are permitted, specify conditions (type, size, number, extra cleaning expectations)
6. Keep signed copies — Store securely for at least two years after the tenancy ends
7. Consult a lawyer — Have your standard lease template reviewed by a legal professional
