Alberta rent increases: no percentage cap, strict timing
Alberta has no general statutory percentage limit on rent increases. The timing and correct notice are still regulated.
Interval and fixed term
The rent normally cannot be increased until 365 days after the start of the tenancy or the most recent rent increase, whichever is later. No rent increase can take effect during a fixed-term rental agreement.
Periodic tenancy notice
- Week-to-week: normally 12 full tenancy weeks written notice.
- Month-to-month: normally three full tenancy months written notice.
- Other periodic tenancy: normally 90 days written notice.
Required contents and complications
For periodic tenancies the written notice must show the date, effective date and landlord signature. Notice periods and tenancy cycles matter: three calendar months is not necessarily the same as three full tenancy months. Some unusual arrangements may need professional review.
How to check if an Alberta rent-increase notice is valid
- Confirm the 365-day rule: the increase cannot take effect until 365 days after the tenancy started or the most recent increase, whichever is later.
- Check whether the tenancy is fixed-term. No rent increase can take effect during a fixed-term agreement.
- The mandatory written notice requirements apply to periodic tenancies. For a month-to-month tenancy, confirm the notice gives three full tenancy months (not three calendar months).
- Check the notice is in writing and includes the date, the effective date, and the landlord’s signature.
- Document the lawful service method, the service date, and the relevant tenancy period. Keep a copy of the notice. The correct calculation of the notice period depends on proper service under the Residential Tenancies Act — do not assume the period starts only when you personally received it.
If any required element is missing or wrong, the increase may not be enforceable. Confirm your specific situation with RTDRS or a qualified Alberta legal professional. See Alberta government — during a tenancy.
