Basement Suite Rent Increases in Alberta

If you rent out a basement suite in Alberta — whether it's a legal secondary suite with city permits or an unregistered conversion — you might wonder whether the rent increase rules are different. For most landlords, they're exactly the same as any other residential tenancy. But there's one critical exemption that can change everything.

The Standard Rules Apply

A basement suite or secondary suite is a residential tenancy under the Residential Tenancies Act (RTA). That means all the standard rent increase rules are in effect:

• 365-day frequency rule: at least 365 consecutive days must pass between the tenancy start (or last increase) and the effective date of the next increase
• Written notice: the notice must include the date of signing, the effective date, the exact new rent amount, the property address, and your signature
• Notice period: three full tenancy months for monthly periodic tenancies, twelve full tenancy weeks for weekly
• No mid-lease increases: rent cannot be raised during a fixed-term lease
• Lawful service: personal delivery, registered mail, or authorized electronic service only

The suite's registration status with the municipality — legal, non-conforming, or unregistered — does not affect these rules. The RTA applies to the residential tenancy arrangement, not to the building permit status.

The Shared-Living Exemption

Here's where it gets different. If the tenant lives in the same premises as the owner or the owner's immediate family and shares living space such as a kitchen or bathroom, the tenancy is exempt from the RTA under Section 2(2).

In practical terms: if you or a member of your immediate family lives upstairs and rents out a basement room that shares the kitchen, the RTA — including its rent increase rules — does not apply. The terms are governed by the agreement and other applicable law.

But if your basement suite is a self-contained unit with its own kitchen, bathroom, and separate entrance, it's a standard residential tenancy under the RTA. The suite doesn't share living space with you, so the exemption doesn't apply — even though it's in the same building.

The dividing line is shared living space, not shared structure. Two self-contained units in one house are two separate tenancies under the RTA.

Unregistered Suites

Some Alberta municipalities require secondary suites to be registered, inspected, or permitted. Calgary and Edmonton both have secondary suite regulations. If your suite isn't registered, you might face municipal bylaw consequences, but it doesn't affect the tenant's rights under the RTA.

An unregistered suite is still a residential tenancy. The tenant is still entitled to the full protections of the RTA, including the 365-day rule, the notice period, and the void-notice provisions. You cannot skip these requirements because the suite lacks a municipal permit.

Rent Includes Bundled Services

Many basement suite landlords include utilities, internet, or parking in the rent. Under the RTA, "rent" is defined broadly as the total consideration the tenant pays — including mandatory fees, utility charges, and parking.

If you currently charge $1,200 per month inclusive of heat and water, you can't restructure it to $1,200 rent plus $100 for utilities. That restructuring adds $100 to what the tenant pays and is legally treated as a rent increase. It must comply with the 365-day rule and the full notice period.

Any unbundling of previously included services triggers the rent increase rules.

Security Deposit Limits After an Increase

When you raise rent on a basement suite tenant, the security deposit stays capped at the amount collected at the start of the tenancy. Under Section 43(2) of the RTA, you cannot demand a deposit top-up to match the new, higher rent.

If the tenant moved in at $1,100 and you collected a $1,100 deposit, the deposit stays at $1,100 even after you raise rent to $1,300.

Getting It Right

Landlords managing a single basement suite without professional support can miss procedural requirements. The filing fee for a tenant challenge starts at just $75.
