If you live in Alberta and have received a rent increase notice that feels unfair or seems to break the rules, you may be able to challenge it. Alberta’s rental law protects tenants from illegal increases, but it's important to know your rights, what counts as illegal, and how to respond effectively.

When Is a Rent Increase Considered Illegal in Alberta?

Alberta's rent increase rules are set out in the Residential Tenancies Act (RTA). A rent increase may be considered illegal if:

• Your lease is for a fixed term and the rent goes up before the term ends.
• You receive less than three full months’ written notice for a rent increase.
• Your landlord tries to increase the rent more than once a year.
• The rental increase notice isn’t served properly or is missing required details.

If you think your landlord hasn’t followed these rules, you may have a valid challenge.

Your Rights and Responsibilities as a Tenant

Alberta tenants have important rights when it comes to rent increases and changing lease terms. To learn more about general tenant rights and obligations in the province, see Tenant Rights and Landlord Rights in Alberta.

Landlords also have legal obligations when notifying tenants about rent increases. Understanding these protections ensures you take the right steps if a problem arises. For more guidance on your financial rights and routine rent payments, read Tenant's Guide to Paying Rent: Rights, Responsibilities, and Tips.

What Is the Proper Process for a Rent Increase?

Landlords in Alberta must follow these procedures when increasing rent:

• Rent increases are only allowed once every 12 months for all types of tenancies.
• A written notice must be served at least three full tenancy months before the new amount takes effect. For example, a notice served on April 1 can only raise rent starting August 1.
• There is no maximum limit on the amount of the increase, but the process must follow the law.

If you have a fixed-term lease, the landlord cannot raise your rent during the term, unless your agreement specifically allows it and you’ve agreed in writing.

Example: Incorrect Notice

Suppose your monthly lease started January 1, and on March 15 your landlord gives notice of a rent increase starting May 1. This would be illegal, because you must receive three full months’ notice – in this example, the earliest legal increase would start July 1.

How to Challenge an Illegal Rent Increase

If you believe your landlord’s rent increase notice is invalid or was issued incorrectly, here’s what you can do:

• Do not pay the increased rent unless and until the matter is resolved legally.
• Write to your landlord (keep a copy) explaining why the notice is not valid, referring to the applicable law.
• Keep all paperwork: notices, lease agreements, emails, and communication records.
• If the issue isn’t resolved, you may apply to the Residential Tenancy Dispute Resolution Service (RTDRS) – the official tribunal handling tenancy disputes in Alberta.

Act promptly. There are time limits and your documentation will help your case at the RTDRS.

Which Forms Should Alberta Tenants Use?

• Notice of Application – RTDRS (Form 4): Use this to formally dispute any rent increase or request an order from the RTDRS. It’s the primary application form for residential tenancy disputes in Alberta.
  See the latest version and instructions at RTDRS Forms and Publications.

How to use it: If you and your landlord cannot resolve the issue directly, fill out Form 4 to start your claim. Pay the fee and submit your supporting documents (lease, notice, correspondence). The RTDRS will schedule a hearing and notify both sides.

The RTDRS is an alternative to court, often faster and more practical for tenants.

Where to Find Alberta’s Tenancy Law

The Residential Tenancies Act (RTA) is the governing legislation for rental increase rules in Alberta.

To understand how rent increases are governed across Canada, and how Alberta compares, you can learn about Understanding Rent Increases: What Tenants Need to Know.

What Happens Next?

If the RTDRS finds the increase illegal, you may not have to pay the higher rent, and the landlord could face penalties. If the dispute is not resolved in your favour, you may appeal, but must comply with the order in the meantime.

The tenant-landlord relationship can sometimes be challenging, but knowing what to expect and how to act if you’re faced with an unexpected rent increase makes a big difference.
