Alberta Security Deposit Rules for Landlords

Maximum Deposit Amount

Under Section 43 of the Residential Tenancies Act (RTA), an Alberta landlord can collect a security deposit (often called a damage deposit) up to the equivalent of one month's rent at the start of the tenancy. That cap is based on the initial rent — if you raise the rent later, you cannot collect an additional deposit to match the new amount.

If the tenancy agreement includes a pet damage deposit, that's a separate matter and comes out of the same one-month maximum. Alberta doesn't authorize a second deposit on top of the one-month cap.

Trust Account Requirements

All security deposit funds must go into an interest-bearing trust account at an Alberta financial institution — a bank, credit union, treasury branch, or trust company — within two banking days of receipt. This is not optional. A landlord who deposits the funds into a personal chequing account or holds cash is breaching Section 44 of the RTA.

The trust account requirement exists so the money is identifiable as the tenant's funds, held in trust, and earning the statutory interest rate. The tenant can ask which institution holds the deposit.

Interest Rates (2024–2026)

The RTA requires landlords to pay interest on security deposits at a rate set annually by regulation. The formula takes the ATB Financial cashable one-year GIC rate on November 1 of the preceding year and subtracts 3.0 percentage points. If the result is zero or negative, no interest is payable.

Interest must be calculated and paid to the tenant annually, unless both parties agree in writing that interest will compound and be paid at the end of the tenancy. In years where the rate is 0.0%, there is nothing to pay or compound.

Returning the Deposit

When the tenancy ends, the landlord has 20 days after the tenant surrenders possession to either return the full deposit plus accrued interest or provide the tenant with a written statement of deductions and return the remaining balance. Deductions must be for actual damages beyond normal wear and tear, unpaid rent, or other amounts the tenant lawfully owes under the RTA.

The 20-day deadline is strict. Missing it does not automatically mean the landlord forfeits the deposit, but it weakens the landlord's position significantly if the tenant files a claim with the RTDRS. Adjudicators expect timely compliance with statutory return obligations.

Move-Out Inspections

A move-out inspection is the landlord's primary evidence for any damage claim. Walk through the unit with the tenant present (or after giving proper notice if the tenant declines), photograph every room, and compare the condition against the move-in inspection report. Date everything.

If you didn't do a move-in inspection, proving damage beyond normal wear and tear becomes much harder. The RTDRS weighs inspection reports heavily — a landlord who can't show the unit's starting condition often loses the damage claim even when the damage is real.

Disputing Deductions at the RTDRS

Either party can file an application with the Residential Tenancy Dispute Resolution Service if they disagree about the deposit. The filing fee is $75, and the RTDRS can order the return of the deposit (or part of it) or confirm that the landlord's deductions were justified.

Common disputes include disagreements over what counts as "normal wear and tear" versus actual damage, deductions for cleaning when the unit was left reasonably clean, and deductions for pre-existing conditions the landlord failed to document at move-in. Photographs, dated inspection reports, and receipts for repair work are the evidence that decides these cases.

The Security Deposit and Tenancy Termination

When you're ending a tenancy — whether for a prescribed reason, substantial breach, or non-payment of rent — the security deposit process runs in parallel with the termination process. Serving a termination notice does not give you early access to the deposit funds, and the deposit cannot be applied as the tenant's last month's rent unless both parties agree in writing.
