Alberta rent increase notice calculator
Alberta has no rent cap: there is no limit on how much a landlord can raise the rent. There are rules on when: at most once a year (365 days), never during a fixed term, and with written notice for periodic tenancies (3 full months for month-to-month, 12 full weeks for week-to-week, 90 days otherwise). This calculator works out those dates. Everything runs in your browser; nothing you type is sent anywhere.

The rules this calculator uses
From the Government of Alberta page During a tenancy, section "Rent increases" (alberta.ca). Last verified: 2026-11-09.
- Landlords cannot increase the rent under a fixed term or periodic tenancy agreement until a minimum of one year (365 days) has passed since the last rent increase or since the start of the tenancy, whichever is later.
- Landlords cannot increase rent during a fixed term.
- There is no limit on the amount by which the landlord may raise the rent.
- The notice must be in writing and include the date, the effective date of the increase and the landlord's signature. This notice is required for a periodic tenancy only.
- Notice required: 12 full tenancy weeks for a week-to-week periodic tenancy, 3 full tenancy months for a month-to-month periodic tenancy, 90 days for any other periodic tenancy.
How the dates are counted
- Month-to-month: the notice-by date is the day before the same date three months earlier (February 1 → October 31), so three whole rental months fall between the notice and the increase. If that day doesn't exist (for example May 31 → February), the calculator uses the earlier, safer date.
- Week-to-week: 85 days before the effective date, so 12 whole rental weeks fall in between.
- Other periodic: 90 days before the effective date.
- One-year rule: the same date one year later (February 29 → March 1). That is never less than 365 days.
- No extra days are added for how the notice is delivered (mail, posting and so on). Allow for that yourself.
For a specific dispute, contact the Residential Tenancy Dispute Resolution Service or Service Alberta's landlord and tenant information line. This calculator does not decide anything for you.
Is there an official Alberta rent increase notice form?
We found none. The Government of Alberta page Forms and documents for landlords and tenants lists fact sheets, inspection reports, a checklist and cleaning list for tenants, and the legislation, but no rent increase notice form (checked 2026-11-09). What the notice must contain is set out on During a tenancy: the notice "must be in writing and include all of the following: the date, the effective date of the increase, the landlord's signature". That page lists only these three items, so the blank below has only those three. It is not an official form and not legal advice.
Checklist (from alberta.ca)
- ☐ The tenancy is periodic (week-to-week, month-to-month or other). The notice is required for a periodic tenancy only, and rent cannot be increased during a fixed term.
- ☐ At least 365 days have passed since the last rent increase or the start of the tenancy, whichever is later.
- ☐ The notice is in writing.
- ☐ It includes the date.
- ☐ It includes the effective date of the increase.
- ☐ It includes the landlord's signature.
- ☐ The tenant gets it in time: 12 full tenancy weeks (week-to-week), 3 full tenancy months (month-to-month) or 90 days (other periodic). The calculator above gives the date.

Keeping track of renewals and notice dates
If you manage several units, a paid spreadsheet by Kyle Falk (Lease & Renewal Tracker) lists every lease with its renewal and notice dates in one place. The Small Landlord Records Bundle includes it with the other landlord record sheets. This calculator stays free either way.
