Security Deposit Rules in Alberta

Under the Alberta Residential Tenancies Act (RTA), a landlord cannot collect more than one month's rent as a security deposit. That cap is a combined ceiling -- it covers the security deposit and any pet deposit together. If your monthly rent is $1,800, the landlord may collect a maximum of $1,800 in total deposits, regardless of how many pets you have or what the lease calls the money.

This rule is frequently misunderstood. Some landlords advertise a "security deposit" of one month plus a separate "damage deposit" or "pet damage deposit." Any amount above one month's rent -- regardless of what it is called -- is a violation of the RTA. You have the right to refuse to pay more than the legal maximum, and paying an excess does not make it legal or enforceable.

If a landlord demands more than one month's rent upfront as a deposit, document the request in writing, decline politely, and consider whether this is a landlord you want to rent from. If you have already paid an excess deposit, you can file a claim with the Residential Tenancy Dispute Resolution Service (RTDRS) to recover the overage.

Once a landlord collects a security deposit, they are legally required to hold it in a trust account at an Alberta financial institution. This means the money must be segregated from the landlord's personal or business funds. The trust account requirement exists to protect tenants -- it ensures the money is still there when the tenancy ends, even if the landlord has cash flow problems or changes ownership of the property.

In practice, many small private landlords are unaware of or do not comply with this requirement. If your landlord cannot demonstrate that your deposit is held in trust, that is a violation of the RTA. It does not mean you will necessarily lose your deposit -- you can still dispute through the RTDRS -- but it is a warning sign about how organized and compliant this landlord is.

Tenants do not need to audit their landlord's banking arrangements, but it is reasonable to ask at the start of the tenancy: "Is the deposit being held in a trust account?" A professional landlord or property management company will answer yes without hesitation.

Alberta law requires landlords to pay interest on security deposits. The rate is set annually by the provincial government. For 2026, the prescribed interest rate is 0%. This means no interest accrues on your deposit this year. For context: the rate was 0.5% in 2025 and 1.6% in 2024, so tenants collecting interest in prior years received a small but real amount.

When your deposit is returned, the landlord is required to account for any interest earned at the prescribed rate for each year the deposit was held. Because the 2026 rate is 0%, a deposit held entirely within 2026 will accrue no interest. A deposit held across multiple years -- say, 2024 through 2026 -- would accrue interest at the rates applicable for each year it was held.

In practical terms, do not expect interest income on a deposit held only in 2026. But if your tenancy spans multiple calendar years, you are entitled to ask for a breakdown of interest when the deposit is returned.

After your tenancy ends, the landlord has 10 days to return your security deposit (plus any applicable interest, minus legitimate deductions) -- but only if they have your forwarding address. This is the most important condition: if you do not provide a forwarding address, the clock does not start. Make sure you give your landlord your new mailing address in writing before or on your move-out date.

If the landlord intends to make deductions, they must provide you with a written statement of account detailing what is being withheld and why. Silence is not acceptable. Vague deductions like "cleaning" or "repairs" without specifics are a red flag. You are entitled to see receipts or estimates for any work claimed against your deposit.

If 10 days pass and you have not received your deposit or a written accounting, that is a violation of the RTA. At this point you should send a written demand (email with read receipt or registered mail) and, if no response follows, file with the RTDRS. The tribunal can order the landlord to return the deposit and may award additional compensation.

This is where most deposit disputes arise. Alberta law is specific: a landlord cannot deduct from your deposit for normal wear and tear. Normal wear and tear is the gradual, unavoidable deterioration that happens with ordinary, reasonable use of a rental unit. Examples of what is not deductible:

• Minor scuffs on walls from furniture or everyday contact
• Small nail holes from hanging pictures
• Faded or lightly worn paint (especially in high-traffic areas)
• Carpet wear from regular foot traffic
• Minor marks on hardwood floors from normal use

Deductions are permitted for damage beyond normal wear. Examples include:

• Large holes punched in walls
• Burns on countertops or carpets
• Broken fixtures (door handles, towel bars) caused by misuse
• Stains that cannot be attributed to normal use
• Excessive filth requiring professional cleaning beyond standard turnover cleaning
• Missing or broken items that were present at move-in

The distinction between wear and tear and damage is tied directly to the move-in inspection report. If an issue was documented at move-in, it cannot be held against you at move-out. If an issue was not documented at move-in and appears at move-out, the landlord can claim it as damage -- which is why the move-in inspection is so critical.

The RTA requires a move-in condition inspection to be completed within one week before or at the start of the tenancy. Both landlord and tenant should sign the completed report. This report is your primary defense against unfair deposit deductions at the end of your tenancy.

Document everything during the move-in inspection: every scuff, stain, chip, and scratch -- no matter how minor. Take date-stamped photos and video walking through every room. If possible, email a copy of the inspection report to yourself immediately after signing so you have a timestamped record.

If your landlord refuses to do a move-in inspection or skips it, make a written note (email the landlord the same day) documenting their refusal. Under the RTA, a landlord who fails to complete a move-in inspection may lose the right to claim against your deposit for damage. However, you should still do your own walkthrough and document conditions regardless.

At move-out, the same inspection process repeats. Comparing the two reports side by side is how legitimate deductions are determined. If the move-in report shows a scuff on the bedroom wall and the same scuff appears at move-out, the landlord cannot charge you for repainting that wall.

If you believe your landlord has wrongfully withheld your deposit or made deductions that are not permitted under the RTA, you can file a claim with the Residential Tenancy Dispute Resolution Service (RTDRS). The RTDRS is an administrative tribunal -- faster and less formal than court -- specifically designed to resolve landlord-tenant disputes in Alberta.

The filing fee for tenants is $75. Hearings are typically scheduled within a few weeks. You will need to bring your lease, the move-in and move-out inspection reports, photos, correspondence with the landlord, and any receipts or estimates you have received. Organize your evidence chronologically before the hearing.

The RTDRS can order the landlord to return your deposit, pay you interest, and in some cases award additional compensation. Orders from the RTDRS are legally binding. If the landlord does not comply, the order can be enforced through the courts. Small claims court (up to $50,000) is an alternative if the RTDRS is not the right fit for your situation.
