Overview of the Alberta Residential Tenancies Act (RTA)

The Residential Tenancies Act (RTA) governs all residential rental relationships in Alberta. As a landlord, understanding your obligations โ€” and your rights โ€” under this legislation is non-negotiable. Here's what you need to know for 2026.

Security Deposits

You may collect a security deposit of up to one month's rent. It must be held in a trust account and returned within 10 days of the tenancy ending (with a written statement of deductions), or 30 days if the tenant disputes deductions. Failure to return the deposit can result in the tenant claiming double the amount.

Rent Increases

Alberta has no rent control. You may increase rent by any amount, but you must provide at least 3 months' written notice before a rent increase takes effect โ€” and only one increase is permitted per 365 days.

Maintenance & Repairs

Landlords must maintain the property in a habitable condition. This includes functional heat (especially critical in Alberta winters), plumbing, electrical systems, and structural soundness. Tenants cannot withhold rent for repairs, but can apply to the RTDRS for relief.

Entry to the Property

You must provide 24 hours' written notice before entering a tenant's unit, except in emergencies. Specify the date, time (between 8amโ€“8pm), and reason for entry.

Evictions (Notice to Vacate)

The notice period depends on the reason: 14 days for substantial breach (e.g., non-payment), 24 hours for immediate safety concerns, and various notice periods for no-fault terminations. Always use the correct prescribed forms from Service Alberta.

Resolving Disputes: The RTDRS

The Residential Tenancy Dispute Resolution Service (RTDRS) is a faster, cheaper alternative to court for resolving tenancy disputes. Applications cost $75 and hearings are typically scheduled within 6โ€“8 weeks. Both landlords and tenants can apply.
