Alberta Landlord-Tenant Laws 2026

Alberta runs its residential tenancies under one statute, with a dedicated dispute service alongside the courts. The Residential Tenancies Act sets the rights and duties of landlords and tenants, and the Residential Tenancy Dispute Resolution Service (RTDRS) — plus Alberta courts — resolves the disputes. This 2026 overview ties the pieces together for landlords and property managers, and links to the deeper guides for each topic.

The anchors: one Act, one dispute service

For Alberta, anchor every policy to the Residential Tenancies Act and the Residential Tenancy Dispute Resolution Service (RTDRS), with the courts as the alternative forum. The most common failure in multi-province portfolios is treating Alberta like British Columbia or Ontario — the deposit rules, the rent-increase mechanics, and the notice periods are all Alberta-specific, and Alberta notably has no rent-control cap where other provinces do.

Two operating rules carry most of the weight: put the province name at the top of every checklist, and separate business judgment from legal procedure. A landlord may decide an increase is warranted or a tenancy should end, but the action still has to move through the Act's timing and notice, and any order comes from the RTDRS or a court.

The four things that trip operators up

Deposits. A security deposit is capped at one month's rent, must be held in an interest-bearing trust account, and cannot be increased mid-tenancy even if rent later rises. See the Alberta security deposit guide.
Rent increases. No provincial cap on the amount, but only once every 365 days, not in the first year, not mid-term in a fixed-term lease, and with three full months' written notice for periodic tenancies. See the Alberta rent increase guide.
Ending a tenancy. Distinct notices tied to the ground — 24-hour for serious damage or an assault/threat, 14-day for a substantial breach, 14-day for non-payment with mandatory pay-to-cure language — with orders from the RTDRS or a court. See the Alberta eviction guide.
Records. Move-in and move-out inspection reports, the ledger, notices, and proof of service are what make any of the above enforceable.

The records that turn policy into evidence

For a property manager, the file for each unit should show the lease, ledger, notices, delivery proof, move-in and move-out inspection reports, dated photos, correspondence, and a chronology someone outside the company can follow. Alberta's dispute process rewards the party with the cleaner record, so recordkeeping discipline is not overhead — it is the case.

Common mistakes

Reusing another province's deposit or notice rules in Alberta, assuming a rent-increase percentage cap exists (it does not), increasing more than once in 365 days or in the first year, changing rent mid-term in a fixed-term lease, serving the wrong end-of-tenancy notice for the ground, omitting the pay-to-cure language from a non-payment notice, skipping inspections, holding the deposit outside an interest-bearing trust account, or treating a notice as self-executing before an RTDRS or court order is in hand.

Managing this in software

Your system should stamp each property with its province, apply Alberta's one-month deposit cap and interest-bearing trust requirement, enforce the once-per-365-days and three-month notice rules without imposing a nonexistent cap, map each end-of-tenancy ground to the correct Alberta notice and period, and require a second review on every compliance event. The goal is simple: never let a correct business decision become a defective legal step.

How Proprietio helps

Proprietio stamps each property with its jurisdiction and applies the local deposit, rent-increase, notice, and eviction rules automatically, with a second-review step on every compliance event — so a correct business decision never becomes a defective legal step.
