Illegal Lease Clauses Tenants Should Watch for in Alberta

Leases & Agreements Alberta published: June 20, 2025 Flag of Alberta

Signing a lease in Alberta is a big step, and it's important for tenants to know their rights. While most landlords use standard, legal forms, some agreements include clauses that are not allowed under Alberta's law. Recognizing illegal lease clauses early helps you protect yourself, avoid disputes, and make confident decisions about your rental home. This article details which lease terms are void or unenforceable in Alberta, what to do if you encounter them, and how to take action if your rights are at risk.

Who Regulates Residential Tenancies in Alberta?

The Residential Tenancy Dispute Resolution Service (RTDRS) is the official tribunal for landlord–tenant disputes in Alberta. If you have questions or need to resolve an issue about your lease agreement, RTDRS provides forms, guidance, and dispute resolution services tailored to Alberta law.

Key Legislation: Residential Tenancies Act (Alberta)

All rental agreements in Alberta must comply with the Residential Tenancies Act and related regulations. Even if you and your landlord sign a lease with certain rules or conditions, the law overrules anything that does not comply. Illegal clauses are simply void — they cannot be enforced.

Examples of Lease Clauses That Are Illegal in Alberta

Some clauses appear in leases but have no legal force. Here are the most common types tenants encounter:

  • No Security of Tenure or Eviction Without Cause: Any clause that says your landlord can evict you without reason before the lease ends, or that tries to take away the notice periods set by law, is illegal.
  • Excessive or Non-Refundable Deposits: Alberta law only allows a security deposit equal to one month's rent and it must be refundable. ‘Non-refundable deposits’ or extra fees for normal wear-and-tear are not permitted. See Understanding Rental Deposits: What Tenants Need to Know for full details.
  • Rent Increases During a Fixed-Term Lease: Any clause claiming rent can be raised before your lease ends (unless you sign a new agreement after the term) is void. Alberta has specific rules about Understanding Rent Increases: What Tenants Need to Know that must be followed.
  • Waiving Your Legal Rights: A lease cannot require a tenant to waive rights under the Residential Tenancies Act, for example, the right to proper notice for entry or eviction, or repair standards to keep your home healthy and safe.
  • Landlord Entry Without Notice: Clauses that allow the landlord to enter your unit without 24 hours’ written notice (except for emergencies) are not valid.
  • No Pets Clauses (with restriction): While landlords in Alberta may restrict pets, a fee described as a ‘pet deposit’ cannot be non-refundable or exceed the one-month maximum for all deposits combined.
  • Unlawful Penalties for Breaking Lease: Fees greater than the landlord's actual loss, or so-called 'penalties' for ending a lease early, are illegal. The landlord may only claim for lost rent and reasonable costs to re-rent.
  • Maintenance and Repairs: Clauses requiring tenants to handle major (landlord's) responsibilities such as furnace repair, window replacement, or structural work are unenforceable. For details, see Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

Landlords cannot include any clause that contradicts Alberta’s tenancy laws. Keep records of your agreement and any illegal clauses you spot.

What Should Tenants Do If Their Lease Includes an Illegal Clause?

Many tenants worry about challenging an illegal clause out of fear of damaging the relationship with their landlord. However, you have important protections under Alberta law. Remember: these clauses are void — you are not legally bound by them.

If you find an illegal clause in your lease, raise your concern in writing to your landlord citing the Residential Tenancies Act. If the dispute continues, you can seek help from Alberta’s RTDRS.

Example: Security Deposit Overcharge

If your landlord asks for two months’ rent as a deposit, politely refer to section 43 of the Residential Tenancies Act, which limits deposits to one month. Repeat your request in writing if needed.

Relevant Official Forms for Alberta Tenants

  • Residential Tenancy Dispute Resolution Service (RTDRS) Application: If your landlord insists on enforcing an illegal lease clause, tenants can submit an Application for Residential Tenancy Dispute Resolution.
    • How it’s used: For example, if you’re being charged illegal penalties or your deposit was not returned properly, this form lets you have your case heard by the RTDRS.

Forms, instructions, and current fees are provided by Alberta RTDRS.

What Happens if an Illegal Clause Was Signed?

Even if you agreed to the clause when signing the lease, it cannot override your statutory rights. Alberta law automatically voids any unlawful section of a residential lease.

Best Practices for Tenants

Before signing, carefully read each section of your lease. If you’re unsure, ask the landlord for clarification or consult Alberta’s tenancy resources. In general:

  • Check for compliance with provincial law
  • Document communication with your landlord
  • Seek advice from tenant support organizations if needed

Being vigilant at lease signing helps you avoid future disputes and settle comfortably into your new home.

  1. Is my lease invalid if it has an illegal clause?
    Generally, your lease is still valid. Only the clause that goes against Alberta law is void; the rest of your agreement stands.
  2. Can a landlord require cleaning/repair fees beyond normal wear and tear?
    No, landlords cannot require you to pay for regular wear and tear. Any clause that says otherwise is unenforceable.
  3. What should I do if my landlord tries to enforce an illegal section of my lease?
    Let your landlord know — in writing — that the clause doesn't comply with the Residential Tenancies Act. If necessary, apply to the RTDRS for a resolution.
  4. Are pet restrictions legal in Alberta?
    Your landlord can decide whether to allow pets, but cannot charge more than the legal deposit maximum or a non-refundable pet fee.
  5. If I already signed a lease with an illegal rule, can I ignore it?
    Yes, unlawful clauses are considered void, even if signed. You don't need to follow them, but keep records in case of a dispute.

Key Takeaways for Alberta Tenants:

  • Illegal lease clauses are void, even if you signed the agreement.
  • Security deposits, rent increases, and landlord entry are strictly regulated.
  • Alberta’s RTDRS can help resolve disputes over lease terms quickly and affordably.

Being informed about your rights under Alberta’s tenancy laws helps you make confident rental decisions and avoid unfair lease conditions.
