Alberta Rent Increase Rules 2026: No Cap, 3-Month Notice, 12-Month Gap

Unlike Ontario (guideline typically 2.5 percent), British Columbia (annual cap set by regulation), Manitoba, and Nova Scotia (5 percent cap through 2027), Alberta imposes no percentage limit on how much a landlord may raise rent at renewal. The market is the ceiling.

This is a defining feature of Alberta rental law. In hot markets, it means rent-increase surprises can be dramatic. In soft markets, it means many landlords voluntarily keep rents flat or offer decreases to retain good tenants. In practice, most Alberta landlords set renewal increases within the local market rate of change, because a departing tenant costs more in turnover and vacancy than a modest renewal.

Section 6(1) of the Residential Tenancies Act requires the landlord to give the tenant at least three months' written notice of any rent increase. Verbal or texted notices are not sufficient. The notice must specify the new rent amount and the effective date.

What counts as valid notice

• •
  In writing.Paper letter, email, or another documented method the parties have agreed to use.
• •
  Delivered at least 90 days (three months) before the effective date.
• •
  Specifies the new rent amount.Not just a percentage; a dollar figure.
• •
  Specifies the effective date.The first day the new rent applies.
• •
  Signed by the landlord or an authorized agent.

Section 6(2) requires at least 12 months between rent increases on the same tenancy, measured from either the start of the tenancy or the last increase, whichever is later. This means a landlord who signed a tenant last November cannot serve a rent-increase notice until next November at the earliest, and even then the increase does not take effect for another three months.

The 12-month clock does not reset when a new tenant moves in; it resets between tenancies. In other words, a landlord can absolutely raise the rent significantly when signing a new tenant after a previous one moves out. The 12-month rule protects incumbent tenants only.

During a fixed-term lease (typically a one-year lease), the rent cannot be increased. The rent stated in the lease is the rent for the entire term. At the end of the term, the landlord may propose a new lease with a new rent, subject to the three-month notice rule if the tenant would otherwise become periodic.

What happens at end of a fixed-term

• •
  Sign a new fixed-term lease.The rent stated in that lease applies for the new term.
• •
  Roll into a periodic (month-to-month) tenancy.By default under Alberta law. The old rent continues until the landlord serves a valid three-month rent-increase notice.
• •
  End the tenancy.Either party can end at the end of a fixed-term without notice on either side (unless the lease specifies otherwise).

If a landlord attempts to enforce a rent increase that violates any of the above, the tenant can:

1. 1
   Continue paying the old rent.The unlawful increase is not enforceable.
2. 2
   Document the notice.Keep the paper trail of what was served and when.
3. 3
   Apply to RTDRS.If the landlord tries to evict for non-payment of the disputed amount. Filing fee is $75.
4. 4
   Consult a tenant advocacy service.The Centre for Public Legal Education Alberta (CPLEA) provides free plain-language guidance.

The Alberta rental market in 2026 has softened from the tightness of 2022-2024. Purpose-built vacancy in Calgary sits at 5 percent, up from 1.4 percent in 2023, and asking rents dropped 4 percent year over year on new listings. In that environment, most landlords are declining to raise rents at renewal, or are proposing token increases (2-4 percent) to signal good faith.

For landlords: A large increase invites the tenant to shop the market. In a softer market, the tenant often finds a comparable unit elsewhere and moves. Turnover costs (vacancy, cleaning, marketing, screening) typically exceed the extra rent gained. Keeping good tenants at fair renewal rates almost always pencils out better than optimizing headline rent.

For tenants: A properly-served rent increase notice is legal even if the increase is large. Your options are to accept, negotiate, or end the tenancy. Negotiation works better than most tenants expect, especially in a soft market. If the landlord has served notice of a large increase, respond in writing with a counter-offer, cite market comparables from SQRFT listings, and explain that you would prefer to stay if the number is reasonable.
